What to do if your Lenovo laptop won't turn on? Lenovo P780 smartphone does not turn on - repair or replacement

For many users, how to troubleshoot problems with a personal computer is a real mystery. Sometimes it can be quite difficult to predict that a particular device will work normally over a long period of time. No one is immune from problems and failures. What should you do if your Lenovo laptop does not turn on? Why might such a situation arise? The following will provide the best tips and tricks to resolve this issue. In fact, it is not at all difficult to deal with this problem; you just need to use the method of elimination. Users quite often rush to take their laptop to a service center. But don't rush right away. It is likely that the problem can be solved without outside help. So what options are possible?

Battery missing

Why might a Lenovo laptop not turn on? It is quite possible that the device simply does not have a battery inserted. This situation is especially relevant when we are talking about working with a device without connecting it via a wire to the network. In this case, fixing the problem can be easy and simple. You just need to insert the battery into the bottom of the laptop. There is a special niche on the bottom panel for this. Then you need to insert the missing part of the laptop into it. After this, you can resume using your device. If this action does not bring results, then do not despair. There are many more options to solve the problem.

Battery charge

A Lenovo laptop may not turn on even if the battery is installed in its rightful place. Here it is possible that the battery simply does not have a charge. In this case, you will not be able to work on the laptop without an additional connection to the power supply. It will be enough to simply connect a special power cable to the machine, and then plug it into a power outlet. Now you just need to wait a little. The light on the back of the laptop should light up to indicate battery charge. Charging the battery will take time, usually several hours. And after that, you will again be able to work with your Lenovo laptop without additional wires. But only until the battery runs out again. Practice shows that the charge lasts for 4 hours on average.

Nutrition

There is another reason why a Lenovo laptop may refuse to turn on. It is somewhat similar to the situation associated with a laptop battery. It cannot be ruled out that there is no connection to a power source. For what reason is this alignment highlighted as a separate item? The fact is that some laptops from the manufacturer Lenovo are equipped with a built-in battery. It is located under the bottom panel, and removing it is not so easy. In this case, it is recommended to find the power cable and plug it into the network, and then connect it to the device. If the problem was a lack of power, the machine will turn on and function. But what to do if this action does not bring a positive result? What other options might there be to solve the problem?

The wire

The problem with your Lenovo laptop refusing to turn on may be a damaged power cord. Such situations are especially relevant for older laptops, when the power cord is often pinched and exposed to various external influences. A problem like this can be quite difficult to diagnose. If you have a similar power cord available, you can try connecting it to the laptop, and then try turning on the device again. If this does not help, then it is better to take the device to a Lenovo service center. They will definitely help you fix the problem. Another alternative solution to the problem would be to purchase a new cable to supply power to the laptop. The new component will work 100%. The computer should turn on accordingly. But what if there is no progress after replacing the wire?

Connectors

What to do if your Lenovo laptop does not turn on? Once you have ruled out all the previously listed options, you need to pay attention to other features. For example, on a connector for connecting to a power device. The thing is that these sockets on laptops sometimes get damaged. On new computers this reason is practically excluded. It is more likely to occur in cases where we are talking about older devices. You can fix the problem by contacting a Lenovo service center. They will help you determine whether the problem is really with the connector, and they will also be able to fix them. Only in some cases will users have to buy a new laptop.

Problems with the video card

What other options might there be? All of the previously listed scenarios are fairly common occurrences. However, they can be easily and quickly eliminated. What to do if a Lenovo laptop displays a black screen? It is important to pay attention to how the device works as a whole. For example, how a cooler works. It can work completely normally, make a low noise and perform its functions. But there is no image on the laptop screen. How then? You need to check your video card. It may be faulty. A black screen instead of a laptop or computer being turned on is a fairly common occurrence when problems arise with the operation of the video card. Inexperienced users would be better off using the services of a Lenovo service center to check this problem. After all, if you interfere, you can easily damage the laptop components. After replacing or repairing the video card, the problem should disappear.

RAM

What to do if your Lenovo laptop still won’t turn on? A similar problem can arise due to a hardware conflict, for example, RAM and video card. The RAM may simply break. This is true for old laptops, or for devices that have been modified to one degree or another. This is especially true in cases where the user independently handled the hardware components of the device. If the problem is in the RAM, then when you turn on the laptop will emit a certain signal. You will definitely hear it. The problem can be solved either by repairing the device at a service center or by purchasing a new device.

What other circumstances can affect the performance of a Lenovo laptop? There are many reasons for this, but identifying them on your own is not as easy as it might seem at first glance. What to do if a Lenovo laptop refuses to work? What should you do if the screen does not turn on, although at first glance everything is in order with the hardware components of the device, all connectors are in working order, the power cord is not damaged, and the battery is also normal? Why is the problem not eliminated? Perhaps it's all about the design of the computer system. A damaged or faulty BIOS quite often brings a lot of problems to users. In this case, the computer may not turn on, often reboot or turn off on its own and may not save everything that was done while working with the device. In this case, only reinstalling or reconfiguring the BIOS will help. This is usually done by service center employees or system administrators. It is not recommended for the average user to work with the BIOS on their own. A poorly executed installation can easily turn a Lenovo laptop into a pile of useless metal. This happens, fortunately, quite rarely.

Hard drive problems

There are also situations when, despite the fact that a laptop from the Lenovo manufacturer turns on normally, it does not boot or the operating system constantly reboots. In this case, you need to make sure that the hard drive is in working condition. If it is in a faulty condition or is missing altogether, then there is absolutely nothing to be surprised about. The gadget actually works, but there is nowhere for it to load the OS. This phenomenon occurs extremely rarely. But it can be easily diagnosed at a service center. In this situation, you will need to supplement the laptop with a hard drive that functions normally. You will need to install the operating system on the hard drive, and then try to work with the device again. If this procedure leads to a positive result, then you don’t have to worry about the integrity of the laptop and its further operation. If this procedure does not bring a positive result and the Lenovo laptop still does not turn on, then the cause of the problem lies elsewhere. What exactly? What else should users pay attention to?

Turns on and off

Sometimes situations arise when a laptop or computer turns on and then turns off. Also, the device may constantly reboot. There is no need to be afraid of such circumstances. In this case, it is recommended to pay attention to the operation of the cooler. Is it functioning normally? If the laptop starts to shut down spontaneously or constantly reboots, then we can come to the conclusion that the culprit is simply overheating of the equipment. It can occur for various reasons. One of them is a clogged cooler. Every laptop needs to be cleaned from time to time. Including the cooler of the device. To eliminate overheating, all possible actions must be taken. You can even replace the fan completely. It is also recommended to pay attention to the position of the cooler. The laptop must be installed at the workplace in such a way that access to oxygen is not blocked in the cooler area. All these recommendations will help restore the functionality of the gadget.

Screen

The problem sometimes lies in the display being faulty. It will theoretically work, but the user will not see the image. If we are talking about damage to the display, then you will need to install a new one on the Lenovo laptop. This can only be done at a service center. However, replacing the display in some cases is not possible. If the display malfunctions, you often have to buy a new laptop. It doesn’t matter at all what manufacturer’s device you are using – Lenovo, ASUS or someone else. The main thing is that the reasons for the malfunction are the same for all laptops. Now it becomes clear why a Lenovo laptop may not work. This article examined various situations. It is worth noting that in such situations the intervention of service center specialists is not always required.

When choosing a phone, each of us pays special attention to its reliability. We read user reviews, study the technical characteristics of the device, etc. And in this regard, gadgets from Lenovo look like one of the best options.

But in any case, sooner or later the smartphone will stop working. There are many reasons for this, and only a specialist can understand exactly why the phone stopped functioning.

But in general terms, it is quite possible to determine why you cannot start your smartphone, if you take into account some of the features of its functioning. In this article, we will tell you why Lenovo phone usually does not boot.

If the phone stops turning on, it is very likely that its battery is faulty. Over time, the battery capacity decreases, and it no longer allows the device to be sufficiently autonomous. This problem is well known to owners of all mobile devices from any manufacturer.

It is quite possible that the reason is that the charger or the connector for connecting it to the smartphone is faulty. As a rule, replacing the battery usually helps in this situation.

Lenovo won't boot due to software failure

Sometimes a Lenovo phone does not turn on due to a software problem. How to distinguish a software malfunction from a hardware one? There is a proven method: if the LED blinks when turned on, then the problem is in the software part.

There are many reasons for software failures. Most often, they result from the user installing software from unverified sources, various applications containing viruses, etc.

If your phone worked fine, and then repeatedly rebooted on its own, and after rebooting does not start, then there are exactly two options:

  1. Contact specialists to determine why your Lenovo phone does not turn on;
  2. Perform a factory reset, in other words, do a Hard Reset;
  3. Reflash your mobile device.

The last two methods actually work even at home if your Lenovo phone does not turn on, and you can easily implement them on your own. But remember: if you did a flashing or Hard Reset, this will automatically delete all data from the smartphone. Therefore, it is recommended to periodically save them on an alternative medium so as not to get into an unpleasant situation. This applies not only to photos and videos, but even to SMS and contacts in the phone book.

But if the phone runs on the Android platform (and Lenovo smartphones operate on it), then everything is much simpler. Most models support data synchronization with a cloud resource. All you need to do is ensure that your contacts and media files are regularly saved to the cloud on the Internet. Then, even if you don’t boot into your phone and you have to reflash it or reset it, all important information will be available from any other gadget after authorization in the system. Well, after repairing or changing the firmware, go back to your own profile from your phone.

Preventing software failures

In order not to wonder “the phone won’t turn on - what to do,” it is best to know how to prevent such a situation. It's not difficult at all and won't require any effort on your part.

It is quite logical that the beginning of the end of a particular operating system is the installation of various applications that in one way or another interfere with normal functioning.

In order for the phone to boot normally, stop installing and using “heavy” applications. When buying a gadget, you get acquainted with its technical characteristics. And if, for example, it is not intended for games and is not equipped with the most powerful video accelerator, it is irrational to install the latest games on such a gadget. Even at medium settings, they will lead to the hardware platform slipping, which will negatively affect the performance and durability of the mobile device.

At least once every couple of months, clean your phone of unnecessary files. They appear regardless of your desire while the phone is working with applications. To do this, use the “Application Manager”, available in the options of any smartphone, or a third-party program. For example, it could be CleanMaster.

If you keep your phone clean, the chances of seeing your phone not turning on will be minimized.

Mechanical breakdowns

Often the problem with phones that won't turn on is mechanical damage or water getting inside the case. Most often, mobile devices do not start due to damage to the processor or matrix.

In such a situation, it is necessary to establish the cause of the breakdown. If you can do this yourself, then take care of timely repair of the gadget. But it’s better to immediately give your smartphone to specialists for diagnostics so that they can fix the problem and you will get a working gadget again.

The phone fell into the water: what to do?

Many people are concerned about what to do if their mobile device does not turn on after falling into water. As you know, the aquatic environment is dangerous for the internal elements of smartphones, so you need to react as quickly as possible.

First, remove the back cover and remove the battery. Use a hairdryer to dry your phone. Place the device in some container with rice - it absorbs moisture perfectly. After a couple of hours, insert the battery back and try to turn on the gadget. If the phone does not turn on even after this, we recommend that you contact a specialist.

The cause of the breakdown is unclear

If you have done everything stated above, but cannot figure out how to turn on the phone, there is only one way out - contact a repairman. If you are not a specialist and try to fix a mobile gadget yourself, you can harm it if you incorrectly determine the cause of the breakdown. There are many reasons why a smartphone may not turn on. And only specialists with sufficient qualifications and experience can find out what happened to your phone.

So take care of your mobile devices, and if you notice any irregularities in their operation, try to prevent the problem so as not to deal with it in the future. Well, if the phone no longer turns on, and it is difficult to visually determine the cause of the problem, we advise you to immediately go to a repair specialist.

If problems arise with a wet gadget, do not connect it to the mains and stop pressing the buttons. as soon as possible and only then follow the advice in this article.

If you are sure that the inside of the smartphone is dry, feel free to continue.

1. Force restart your device

Your phone may be turned on but just frozen. In this case, the screen may be dark and not respond to any actions. So first try restarting your device using the hardware keys.

How to Force Restart iPhone

On iPhone SE, iPhone 6s, iPhone 6s Plus, and older models, hold the Home key and the top (or side) button for 10 seconds or more until the Apple logo appears.

On an iPhone 7 or iPhone 7 Plus, hold down the Side key and the Volume Down button for 10 seconds or more until you see the Apple logo.

On an iPhone 8 or iPhone 8 Plus, hold and immediately release the volume up key and then the volume down key. After that, press and hold the Side button until the Apple logo appears.

How to force restart your Android smartphone

Press the Power button and Volume Down key at the same time and hold them for 10-15 seconds. If successful, the device will reboot automatically or display a menu on the screen in which you will need to select the restart command.

Some Android smartphones can reboot using other buttons. If the device does not respond, search the Internet for a key combination to restart your particular model.

2. Take out the battery and put it back

If your phone has a removable battery, remove the cover and remove the battery from the device. Wait at least 30 seconds and put the battery back. Then try to turn on the phone in the usual way - using the power button.

3. Put your phone on charge

Connect your phone to a power outlet using the original charger. If within an hour the charging indicator does not appear on the display and you cannot turn on the device, check the integrity and cleanliness of the connector, as well as the condition of the power cable and adapter. If possible, try different outlets, replace the cable and/or adapter.

4. Reset the device to factory settings

If after trying to turn on the screen the screen lights up, but the device does not boot properly, try restoring the factory settings using the hardware buttons.

During a system reset, you may lose personal data that was not synchronized with the server. Don't do this if you're afraid of erasing important information.

How to restore original settings on iPhone

Connect your phone to your computer using a cable and launch iTunes. Then force restart your iPhone (see step 1). When you see the Apple logo, continue to hold the buttons until recovery mode appears on the smartphone screen.

After this, a window with further instructions should appear on your computer monitor. Click "Update" and follow the system prompts.

iTunes will download the necessary software for your phone. If this process takes more than 15 minutes, the iPhone may exit recovery mode. In this case, press the forced restart buttons again and hold them until the device returns to this mode.

If the update works, the phone can turn on without resetting the system. If not, then in the iTunes window, click "Restore" to restore the factory settings.

How to restore original settings on an Android smartphone

Make sure your smartphone is turned off and try the following combinations to reset:

  • Volume up key + power button;
  • Volume down key + power button;
  • Volume down key + Volume up key + Power button;
  • Volume Down key + Power button + Home key.

You need to press all the keys at the same time and hold them for about 10–15 seconds. After this, a special menu will appear on the screen, in which you should select the Recovery item, and then the Wipe data / factory reset command. If you don’t see this command in Recovery mode, hold down the power button and momentarily press the volume up key.

After these steps, the smartphone should return to its original settings within a few minutes. If none of the key combinations work or you do not find the necessary commands in the service menu, look for reset instructions for your device model.

Some users are faced with the fact that their Lenovo laptop does not start. This can happen for a number of reasons. Let's look at the most common of them.

What to do first:

  • make sure the outlet is working properly by connecting another electrical appliance;
  • check the functionality of the charger and power cord;
  • If possible, remove the battery and try to turn on the computer.

Due to a malfunction of one of the components, the system may not start. Check the charge indicator near the power input. If it lights up, most likely there is a short circuit in one of the system elements. To determine which one, disconnect as many devices as possible from the motherboard: flash drives, floppy drive, hard drive, RAM, etc.

If after this the computer begins to respond to the power button, connect one device to it after each reboot. This will help identify the faulty component. Once you have identified the problem, check again. If the result is confirmed, replace the faulty device.

Problems with BIOS initialization

Problems with BIOS initialization are indicated by failures during the startup test (POST). Usually the computer tries to start, but due to failures it constantly reboots. In some cases, we see a black screen and the POST check does not run.

This can happen for several reasons:

  • The battery is shorting. Due to a faulty battery, the laptop may restart at the very first boot stage. To solve the problem, try removing the battery and turning on the computer without it.
  • CPU overheating. This may be indicated by the computer turning off at various boot stages. To resolve the problem, replace the thermal paste and remove dust and debris from the cooling system.
  • BIOS malfunction. One of the most common reasons why a Lenovo laptop may not turn on is a malfunction. In some cases, the microcircuit fails and needs to be replaced, in others you can get by with flashing it. Download the firmware from the official Lenovo website and try to restore the chip's functionality. Use the latest firmware versions, which can be found here: https://support.lenovo.com
  • Breakdown of the south bridge. If the cooling system is not cleaned on time, the south bridge of the motherboard may fail. Take the computer to a service center to find out more details about the problem. You may need to replace the motherboard or, if repair is not practical, purchase a new laptop.

Errors while loading Windows

The operating system may not start for a number of reasons:

  • North bridge failure. This kind of malfunction can only be repaired at a service center.
  • The RAM board has failed. Replace the faulty chip.
  • Errors when reading the hard disk. Check the disk for errors from one of the diagnostic programs.
  • The operating system loader is faulty. Use a disk or flash drive for recovery.
  • Windows crashes due to a virus attack. Reinstall the operating system using the image disk. Save your data before surgery.

There is no image on the Lenovo laptop display

If your computer appears to start but there is no image on the display, this could indicate several possible problems:

  • Video card malfunction. In some cases, the display may show single-color fills, artifacts, etc.
  • The display or backlight is faulty. Connect an external display to your laptop. If the image appears, it pinpoints the problem mentioned.
  • Loop fault. In this case, the image may sometimes appear, especially if you try to open/close the lid or press on the top part above the keyboard.
  • Problems with drivers or BIOS. You can try updating the drivers and BIOS firmware to the latest versions.

Most owners of modern gadgets have more than once encountered situations where the device malfunctioned or did not respond to commands. Unfortunately, almost all smartphones fail from time to time, regardless of manufacturer and price.

Today we will look at the problem when a Lenovo phone does not turn on, and we will look at the reasons for this.

Lenovo cell phones often suffer from problems in software and hardware components, especially if we are talking about budget models. One of the most common is spontaneous shutdown and lack of subsequent response to various user actions. Although the situation seems scary at first glance, only in extreme cases will you need service repairs or replacement of your smartphone. There are three types of sources of these breakdowns:

  • Hardware - a problem in the hardware after falls, temperature changes, tests by the sun, moisture and sand.
  • Software – directly concerns the operating system, viruses and crashes.
  • External – most often, a breakdown of the charger is mistaken for a problem in the smartphone itself.

Let's take a closer look at the reasons why your Lenovo phone won't turn on and how to solve them.

Trouble-shooting

In this section, we will look at the most common faults that cause Lenovo to not turn on:

  • Completely discharged battery and other related battery problems.
  • Firmware update failures.
  • Software problems.
  • Virus attack.
  • Mechanical damage to internal parts.

Battery completely discharged

Battery problems can be temporary or permanent, and they have different solutions:


Incorrect system update

From time to time, the Android OS firmware and its shell are updated, but glitches may occur during the process. Often, after installing a new version of the system, equipment turns into a non-working “brick”. However, do not rush to replace it with another model; this can be solved by rolling back to factory settings.

It is done using Recovery Mode. Three buttons are pressed simultaneously in the following sequence:

  • Volume rocker.
  • Without releasing the previous one, return to the Desktop key.
  • In parallel with them there is a power on and off button.

A menu will appear on the screen. The pointer moves with the volume rocker up and down respectively. You must select Factory Reset, confirm your choice and wait for the process to complete.

If after this the smart device does not work, then you need to contact a specialist, and he will do the flashing of the system himself.

Software glitches

Even more often, Android-based cell phones do not start due to various kinds of software glitches. The manufacturer and system developers have provided for such scenarios, so they recommend resetting the settings in such cases. We have already discussed how to do it above.

Please note that on some models, pressing the keys sequentially will not work to launch the recovery mode. It is started by a special button on the end of the case, which looks like a small hole, using a needle or a special pin that comes with the kit.

Viruses

Viruses are another popular reason for difficulties with Android technology. They arrive by downloading files and applications from unknown sources, and can seriously damage system data necessary for startup. Most likely, a flashing will be required, which will completely delete the information. But in some cases, service center specialists still undertake manual cleaning of the system storage from viruses and malware.

You can avoid this outcome by first downloading anti-virus software, for example, Dr.Web or ESET.

Mechanical damage and moisture ingress

Let's look at the most popular types of mechanical damage that prevent switching on:

  • Screen failure (malfunction of the cable, display, or moisture ingress through the seams).
  • The charging socket is dirty. Dust, fabric threads from clothes or crumbs get into it. you need to be careful, using a regular needle.
  • Damage to gadget contacts with batteries. This can be either oxidation or mechanical stress that led to deformation.
  • Damaged power button. If the device is new, then most likely it is a factory defect.
  • The worst option is a burnt-out power controller that controls charging.
