Lenovo tab a10 does not turn on. Lenovo tablet contacts are dirty. Why does the Lenovo tablet not turn on?

Tablets have already become common gadgets. They are essentially compact computers who are able to solve various tasks. This article will talk about how to turn on the tablet if it does not turn on, the power button is broken, etc.

Problem solving

It would seem that turning on the Lenovo tablet is not difficult, because you just need to hold down the power button and after a few seconds the familiar manufacturer logo should appear on the screen. But if the device is damaged or programs were previously installed incorrectly, the gadget may not turn on. Below we will describe ways to solve problems with your tablet. Perhaps one of them will help restore normal work devices.

Power button broken

The power button on tablets usually performs several functions: turning off the device, as well as unlocking it. If it fails, then you can try to turn on the gadget in several ways.

The simplest solution is to connect a charger. Lenovo tablet should turn on automatically. If the power button is broken, then you should disable the screen lock, since the gadget cannot be unlocked and you will have to constantly connect the charger to it.
If the power button is stuck inside the case, you need to remove it. back panel and try to put the key in its place. It is worth noting that you should only do this if you are confident that you can cope with this task.
If you were unable to repair the button yourself, you must take the tablet to service center. Qualified specialists will solve the problem in short time. The cost of replacing or repairing a button should not be too high, since the repair is essentially simple.

Tablet won't turn on

A Lenovo gadget may not turn on for a number of reasons. You can try connecting the charger; if charging occurs, then perhaps the battery was simply completely discharged. Two more possible solutions– boot the tablet in safe mode and reset the settings (described in more detail in the paragraph below).

If all attempts to restore the device’s operation are in vain, then you need to use the services of a service center technician.

Endless tablet loading

The reason for this in most cases is software glitch. When you turn on the gadget, the download usually stops at Android logo. You can try to correct the situation by resetting the settings.

Hard Reset on different devices may vary, so the instructions below may not apply to any tablet. Resetting the settings deletes all data and files.

How to reset settings:

Turn off the tablet, remove the memory card and SIM card.
Press the volume down or up button and the power key for 5-10 seconds.
Should appear special menu, where you need to select “Settings” – “Format System” – “ Reset Android" You need to switch between items using the volume buttons.
The Lenovo tablet will reboot and with any luck it will work normally.

You can write your questions in the comments. Also, if you know other methods for solving problems with tablets, be sure to share this information, as it will be useful to other users.

None of the tablet manufacturers Samsung Galaxy Tab 2, Tab 3, Tab 4, Note, Lenovo Yoga, Prestige, Asus Zenpad, Irbis, Digma Optima, explay, Huawei, Acer, texet, Megafon, oysters, Sony, nexus, ousters, explay, dns, dexp, supra, tesla, wexler, turbokids princess, iconbit and others do not hide the fact that they can freeze.

A simple reboot usually solves the problem. You need to turn it off and on again (before turning it on, it doesn’t hurt to take out the battery if it’s removable).

Who doesn’t know how to turn off the tablet when it freezes when turned on on the screensaver and does not respond to anything?

Sometimes the tablet hangs due to program bugs, for example, when there are too many of them running at once, but most often the memory is to blame. In general, the following reasons can be identified:

lack of free memory;
damage to board contacts;
connecting incompatible equipment.
Installing applications not intended for this device;
virus attack;
a mistake in system files operating system;
factory settings failure.

When eliminating freezes, you first need to identify the cause - make a diagnosis:

this happens all the time;
started freezing after the update;
The Internet picture, application, or inscription freezes when loading, in games, videos, for example, on YouTube or when watching movies;
the sensor or system freezes;
Freezes while charging or at any time;
it gets stuck and freezes after 10 minutes, or if it works, it doesn’t slow down;
Freezes in sleep mode or always.

Having found out at least the reasons above, it will be much easier for you to determine what to do to correct them.

Here I will give only basic recommendations on what to do, but there may also be rare individual ones in certain Android phones, such as Lenovo a3000, Irbis tz60, Prestige multipad 7.0, dixon g750, Samsung Galaxy note n8000, texet tm 9720, megafon login 2, Huawei media pad 10, Onda v811, pocketbook a10 and any Chinese.

The first thing to do if your Android tablet keeps freezing

As I wrote above, it usually solves the problem simple reboot(manufacturers recommend doing this at least once a week and have even integrated a tool for doing it yourself automatic reboot, even daily).

If your tablet is Lenovo yoga, Samsung galaxy tab,asus, prestigio multipad, huawei, asus zenpad, dns, Irbis or digma began to freeze constantly, then the first thing I recommend doing is to start it in safe mode. Who doesn't know how

Safe mode Very few tablet owners use Android because they don’t know about it. Even on the Internet there are few reminders about it.

How can he help you? You will determine whether the reason is software or hardware, since only built-in applications and functions will work in it. If the freezes stop, then the problem is in the applications that you installed yourself.

What to do if the tablet freezes using built-in applications

If there are many applications or processes running at once, then there may be a shortage random access memory. This is especially true for inexpensive tablets.

They usually have very little memory, both RAM and internal system memory - it may not even be enough to store one movie.

Tablet owners often install a lot various applications and games, but remember that everything has its limits.

If we cram too many games or programs onto our device, it may start to run slowly, even after overclocking the processor and regularly freeing up memory.

Don't forget to systematically remove Not required applications, many of whom always work in background and aimlessly consume CPU and battery resources at a surprisingly fast pace.

Therefore, try, as far as possible, to remove everything that is unnecessary and see what happens.

What to do if the tablet freezes and does not respond to the screen

If on a tablet touch screen does not respond to anything, this does not necessarily mean that it is frozen.

The reason for the lack of response to touches may be damage to the screen itself. This mostly happens through impacts.

Less often through errors software systems. If you haven't mechanically damaged your screen, there are a few things you can try.

Try restarting or rebooting your device. If you have connected peripherals, check if they are blocking the screen.

You can also calibrate the screen (some models have a built-in tool for this).

If your tablet stops responding while in use specific application, try to remove it.

If your tablet still freezes even after all the methods in this article, you will most likely need to perform a factory reset.

Reset the device to initial settings: In settings, click " Backup and reset" > "Factory settings" > "Reset tablet" > "Erase everything".

However, do not forget to back up all important data in your internal memory devices.

ATTENTION: you may have security protection enabled, then when you try to restore factory settings you will be prompted to enter your username and password Google account, which you used to enable protection.

The tablet slows down and freezes - speed it up

Try to clear your data cache from time to time. For this you can use applications, for example - Task Manager ES, which offers a small desktop widget.

You can also use the application - Task Killer which makes it easy to complete everything running processes in the background.

You can also overclock the processor - for this there is also special programs, but AT YOUR OWN RISK (you can increase the frequency from 1 GHz to 1.2 GHz, which has positive influence speed, but unfortunately has a negative impact on battery life.

REMEMBER!!! If you want to overclock your processor, you need to do it gradually and not immediately set the available maximum value, because you may damage the device.

You can also set the lowest acceptable clock frequency processor and its operating mode.

Conclusion

Freezes more often Chinese fakes or little-known manufacturers. This is not a disaster and most freezes can be fixed on your own.

There are, of course, cases when you can’t do without a specialist - it all depends on the reason: hardware or system.

Fixing hardware problems is much more difficult than software problems, which are usually fixed at home.

If the tablet is already old, then take a closer look to see if the battery is accidentally swollen - perhaps it’s time to change it.

If the tablet worked stably and suddenly began to freeze, then remember what you did with it in Lately and try to reverse the device.

Perhaps your tablet needs to be reflashed or updated, and do not forget about viruses that can “load” the processor to 100%, then it will definitely start to freeze. Good luck.

Modern electronics require both hardware power and appropriate software. If the most powerful Android tablet It’s impossible to launch - there’s no point in it. However, in most cases, a device caught in such a bind can be saved.

Nature of the problem

Why do problems arise when the tablet turns on, but does not load beyond the logo (as do smartphones), or does not turn on at all?

Flashing error. Similar incidents happen if you (or a would-be repairman from a service center) try to install firmware intended for another device on your tablet. Perhaps during the installation process there was a sudden power failure and the computer from which you were installing the firmware turned off.
Full discharge batteries. Enough rare reason, however, does occur (particularly with Lenovo tablets).
Memory clogged. When downloading to anyone modern device needed free memory(). If there are problems with it, the tablet may take an unbearably long time to load and may never load completely.
Mechanical damage. As a rule, they manifest themselves in the complete refusal of the device to turn on, but there are exceptions.

When the tablet is turned off, we are unlikely to be able to carry out an accurate diagnosis (except in cases mechanical damage, traces of which remained on the body). But the recovery methods are general in any case.

How to solve the problem?

Recovery Mode

Modern Android devices are equipped with by special means recovery. Mode Recovery Mode designed to work with the system “at a low level”. Through this mode you can set new firmware or a program deeply embedded in the system (for example, Google Apps). But the easiest way is to enter Recovery Mode and reset the system.

For different models Logging into recovery is done in different ways. As a rule, to do this, you need to turn off the device, and turn it on again, hold down the power button together with the volume up (or down) key that has already been pressed. However, some manufacturers show imagination and use own solution(for example, with a “Home” button – like Apple’s). Therefore, before the procedure, search the Internet for instructions on how to enter recovery mode specifically on your model.

In the menu that appears touchscreen won't work. You need to move up and down its items using the volume buttons, and confirm with the power button. Select Wipe Data Factory(factory reset), apply it. After that, select Reset and reboot the tablet in normal mode.

Of course, if you didn't backup copies, then your applications and personal data will be reset. But they are not difficult to restore, especially if you have enabled permanent .

Flashing via computer

If you enter Recovery mode If it doesn’t work, then try restoring the tablet via your computer. There are many utilities for this purpose, but for each specific model(or chipset) you need to select the right application.

So, for tablets on NVidia processors developer released special application with the name NVFlash. To flash models on RockChip, there is the RockChip RK Batch Tool application. Other manufacturers also release their own flashing utilities. It is important to study the characteristics of your tablet and find the appropriate software.

Important: find the firmware version that exactly matches the hardware properties of your tablet. Otherwise, the gadget can be completely destroyed.

Hardware solution

Sometimes using software methods It is not possible to save the device at all. Then the only solution is to completely change the main board with all the chips. As a rule, it can be ordered in online stores (most often in Chinese). If you are confident in the straightness of your hands and have necessary equipment(you’re unlikely to be able to do this with a simple soldering iron with a wide tip and a screwdriver), then you can carry out the procedure yourself. It will cost much less than buying a new tablet.

Users who are not confident in their abilities can contact service centers. Yes, the procedure there will be somewhat more expensive. But you will have to wait less, and the repairs will be carried out efficiently. And also cheaper than buying a new similar tablet.

Yes, your personal data and settings will inevitably be lost. But (see above) they can be restored through cloud services or just manually.

It’s important to know how to prevent such problems from occurring.

If you want to be ready for similar problems and get out of a difficult situation without losses, we advise you to do the following things:

Enable data synchronization in all accounts you trust: first of all Google. Activate backup photo uploads to Google+ or Facebook. By default, photos are saved in hidden albums, available only to you. If something goes wrong with your device, you can restore all your data after restoring it (or buying a new one).
Make regular backup copies of applications, preferably to a memory card or even to cloud storage. We recommend the application Titanium Backup, which can save not only the applications themselves, but also their settings and data, and also send copies of them to the Dropbox server. Moreover, we advise you to buy licensed copy this application: in case of problems it will pay off.
Don't clog up your tablet's memory. Try to install only the applications and games you need most, and if possible, install them on a memory card. When choosing a card, pay attention to at least class 10, and preferably UHS-I. Only such cards will provide you with decent operating speed. We categorically do not recommend saving on small things and buying class 4 cards.
Protect your device from physical damage. The advice is no longer new, but never superfluous.

Lenovo TAB 2 X30L factory reset

Attention!

To perform a hard reset correctly, the battery must be charged to approximately 80%.
Videos and images for some operations may not exactly match your tablet model.
Once the factory reset is completed, all personal data and applications installed in the memory will be deleted.

Android tablets have already replaced desktop PCs and TVs for many, becoming part of our Everyday life. With Lenovo Tab you can re-read your favorite novel or call your friends wherever they are. Therefore, the unexpected shutdown of the device and lack of response to any of your actions comes as a shock. The owners of these devices immediately run to the service center and pay for imaginary services that actually take no more than an hour of work.

But what then should you do if the tablet goes down, and is it possible to revive it without aggravating the problem? And why did Android turn off even though the battery was not dead?

Diagnostics

Have you noticed that your tablet won't turn on or charge? Preliminary disassembly of the device, with the search for a broken part or fallen wiring, is not The best decision. It is much more effective to conduct an initial diagnosis and find out the reasons why the accessory does not turn on or charge.

The problem is that why the device turns off by itself is not so easy to find out, because even flagship models It only takes a couple of months of work to start to freeze. And now the gadget just turns off and doesn’t turn on, and doesn’t respond to charging. What to do if this happens?

Have you spilled water on your tablet or dropped it, but your Android just turned off and won’t turn on and doesn’t respond to charging? The problem most likely lies in the software.

The reason that the tablet passed out and in best case scenario The logo lights up at startup, and then the device suddenly turns off - there may be an OS update.

If it does not turn on at all, then it is worth checking the health of the battery and charger. It is possible that the device simply suddenly discharged. If it does not turn on, there may simply be no power. How to fix such a breakdown and what not to do?

Problems with the power supply

If the tablet charges but does not turn on, the OS is to blame. But if the gadget refuses to even charge, what is the reason for the breakdown? Here, the Lenovo Yoga Tablet may have problems with the power supply, which can easily fail if used incorrectly.

Your tablet won't turn on? Remember the last time it was charging and whether the indicator was on then. After that, take the power supply and test it on other accessories. Gadgets not responding at all? This means that the main reason that the tablet does not start is a faulty power supply.

And if the devices are charging smoothly, but the Lenovo device still does not start, then it’s worth checking the other two possible breakdown– battery and power connector. A device with such symptoms does not start due to a dead and completely discharged battery.

The guess is checked in the same way as with the power supply - just move the battery to another device, and then connect the device to the network. If the battery starts to charge, the tablet does not work due to a broken connector. I ignored all your actions and the other gadget did not start - the battery needs to be changed.

Hardware failures

Not only an unexpected system update causes the tablet to turn off, but also various hardware failures. This could be either a manufacturing defect or the consequences of improper use of the tablet.

Due to excessive humidity or low temperatures Condensation can lead to board corrosion. Extreme temperatures also cause battery degradation. Therefore, you should not immediately complain about the update if the accessory is switched off. This may be a consequence of improper use. Hardware failures are much more serious than a software failure, so you shouldn’t fix them yourself.

When disassembling the gadget, you can additionally damage several tracks and only aggravate the situation. Not to mention, when cleaning a board from rust, never pour alcohol into it. The permissible maximum is to wipe the damaged area with soaked cotton wool, after which remove the remaining dangerous solution with a regular damp cloth.

And if you have something more serious than rust on parts and it’s wrong installed update– you should contact a professional service center.

OS errors

Most often, accessories turn into “bricks” due to errors in the OS. The reason for this is an update or incorrect installation of pirated firmware by the user, after which the Lenovo tablet stopped starting.

This is a common problem and it’s quite easy to fix; the main thing is not to panic and not to use methods that are dangerous to the device when disassembling. Do not close any contacts and preferably do not touch the inside of the device at all. This will void the warranty until you find out the cause of the problem.

We reset the system

If you didn’t reflash anything, and the harbinger that the Lenovo tablet turned off and the screen went dark was an ill-fated update, then the only solution is to reset the system. You need to use factory or user backups to remove all manipulations with the OS. This will also delete all information with media files stored on the device. However, the SD card will not be affected.

You need to hold down the Volume Down and Power buttons so you can launch Recovery. This is an application built into the board's memory. It shows all the basic information about the accessory and allows you to perform basic manipulations with the device’s memory.

There, find the file management button and “factory reset”, after which a reboot will occur. In just a minute you will again have complete control at your disposal. working device without any hint of previous damage.

If Recovery does not start, try repeating the steps described above after complete discharge gadget. To do this, leave it for several days so that the residual battery charge evaporates, and then connect it to power again for 10-20 minutes.

Have you done everything according to the instructions, but the tablet does not start or constantly reboots? Then a simple system rollback will no longer help the device and you will need to completely reflash the accessory.

Flashing

If during the installation of the firmware the screen goes out and the tablet switches off (shows no signs of life and does not respond to button presses), but the battery is not discharged and is full of energy, we will prepare for the worst.

When installing a pirated OS, you may have allowed fatal error, which led to the complete erasure of the previous system and the incorrect functioning of the new one. The accessory itself is fine and the hardware is functional, but without the desired program– she just doesn’t understand what to do when you press the start button. Correcting such an oversight is also quite simple.

After complete discharge, connect the device to the PC and wait until it is somehow recognized by the system. The computer will not want to perceive the device correctly, because it does not have digital signature. But if he is at least somehow recognized, that will already be enough.

Download the firmware reinstallation application for Android and latest version OS from the official website. Choose a system for your needs specific device, if you don't want the screen to go dark again. Wait a couple of minutes to half an hour for the firmware to install, then start the device.

Conclusion

The device breaks down when incorrect installation systems or failed update from the developers. The main thing is not to panic, because any software errors fixable! Try to apply the tips described above. We analyzed each of them in detail possible reasons breakdowns, and also outlined ways to correct them.
