If your phone does not turn on, this can make any user nervous, but in any case, before taking the device to a service center, you can try to provide first aid to resuscitate the smartphone. Problems due to which the phone does not turn on can be either software, for example, a problem with the firmware due to an unsuccessful update, or hardware, for example, due to a failed battery.
Below we have tried to put together a lot of tips that will help you figure out why your phone won't turn on. If none of the tips helped you, please describe your problem in the comments.
The phone does not turn on after repair.
If you decide to disassemble the phone yourself, and after assembly it does not turn on, then the problem may be that you simply forgot to connect power to the motherboard of your device. You must disassemble it again and make sure that the power supply circuit from the battery to the motherboard is not broken and all cables are in place. If you have a multimeter, try checking the voltage on the battery, or after assembling the phone, try putting it on charge. Almost all phones notify you when charging starts, even if the device is turned off.
What is Root
Root (from the English root - root; read "root"), or superuser - a special account in UNIX-like systems with an identifier (UID, User IDentifier) 0, the owner of which has the right to perform all operations without exception. By having access to the main administrator account, you automatically have not only full control over the operating system with the ability to customize your device according to your preferences, but also a loophole for uninvited guests.
What to do if water gets into your smartphone
Let's look at the hardware reasons why the smartphone won't turn on. One of the reasons may be falling into water. What to do if your phone falls into water? First, remove the battery, you need to do this as quickly as possible, then dry your smartphone with a hairdryer. Control the air; it should not be hot, otherwise the touch glass and some other components will simply begin to peel off. Then, without inserting the battery into the smartphone, put it in a warm place. It is worth noting that you do not have much chance of salvation and it may not be possible without losses. In particular, the buttons on the device may stop working. If you have dried your smartphone, but it does not turn on, it needs repair at a service center. The worst thing that can happen is replacing the motherboard, which, by the way, costs as much as the smartphone itself.
Option #1. Reboot
We are all accustomed to the fact that if some equipment does not work, then it needs to be rebooted. And it is not at all necessary to find out why exactly it does not start or starts to turn on, but does not load completely. There are a huge number of reasons for failures, and even experts cannot always name the problem you encountered in a particular case.
So if Lenovo A319 does not boot or freezes when turned on, the best and easiest way to resolve the issue is to reboot the phone.
Have you tried rebooting your device but that didn't help? Then repeat it five more times. Getting the system to boot normally is not so easy, but repeated reboots are successful in the vast majority of cases.
The smartphone does not turn on after being completely discharged.
This problem is observed in some modern smartphones. In particular, Sony phones. Some Sony phones had such a feature that it was impossible to turn them on after being completely discharged if the phone was in this state for a long time. One thing helps - long-term charging of the battery with a current of 2A. And these are almost all chargers.
In any case, as I already wrote above, you need to put your smartphone on charge for several hours. Usually the problem goes away on its own. You can try a charger with a higher amperage, for example, 1.5 or 2 Amps.
Also try doing a hard reset of your smartphone.
Check the battery. The phone may not turn on due to a faulty battery.
This is a must. If you have a removable battery and can install another one, do so. Sometimes, although not often, the problem that prevents your smartphone from turning on may be the battery. By the way, is your battery fully charged? Maybe this is the case?
With some phones, especially if the phone is several years old, the actual battery charge may not match what your phone shows. If your phone won't turn on, try charging it for a few hours. It is possible that the battery will charge and the phone will turn on.
The battery wears out very quickly. Many mobile phone manufacturers provide a one-year warranty on the device itself, and half a year on the battery. The reason for battery failure is quite simple - a very heavy load on it. We constantly charge our phone, and as you know, batteries lose their charge with each charge-discharge cycle. For example, standard lithium-ion batteries installed in our phones work properly under load for no more than two and a half years.
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 could have made a fatal mistake, 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 functions, but without the necessary program - it simply does not understand what to do when you press the start button. Correcting such an oversight is also quite simple.
Check the charger.
If your smartphone is dead and it won’t turn on again, maybe it’s a problem with charging? Try charging your device from your computer. If within half an hour the phone shows no signs of life, the problem is not with the charger. If the phone seems to be charging, but cannot charge, check the charger on another phone. It is quite possible that it will need to be replaced with a new one.
Installing the firmware mode driver
For Windows 7/XP, right-click on the “My Computer” shortcut. Select “Management” - “Device Manager”.
Then we remove the battery from the gadget and connect it to the computer. An unidentified device will appear in Device Manager for about a couple of seconds.
Then, until it disappears, right-click on it and select “Update Driver”. In the window that opens, tap on the item “Search for drivers on this computer.”
Now we just have to indicate the path where we unpacked the driver (for me this is the desktop). Click the “Browse” button. Select our driver and click “Ok”.
In the window that opens, confirm by clicking on the “Next” button. The driver installation process will begin. Click the “Close” button.
If everything was done correctly, the following device should appear in the device manager for a couple of seconds.
The phone does not turn on after being dropped. Mechanical damage.
Smartphone manufacturers like to say that their phones cannot be scratched, drowned or broken. Manufacturers give their phones Gorilla Glass screen protection, IP67 water resistance, shockproof casing, and so on. Despite all the phone protection measures taken by companies, it often happens that the phone does not turn on after being dropped. For example, on asphalt or falling into water. Unfortunately, all that can be done at home after a fall is to see if the battery, power cable or display cable has come loose, if there is a sound or vibration signal to turn it on.
It’s unlikely that you can do anything more with a dropped phone at home. To do this, you need to check the voltage on the battery and on the system board. If your phone is dropped and won’t turn on, and you don’t have the necessary tools at home, you will have to take the phone to a service center.
