Lenovo P780 smartphone does not turn on - repair or replacement?

Lenovo is a Chinese popular company. Although its equipment is manufactured in China, Lenovo is one of the few companies that produces truly high-quality products. Many products can be found much cheaper than competitors, while they are of better quality. Of course, not everything is so smooth for this company either. Some smartphones, computers, and laptops have shortcomings that become apparent during long-term use.

Now we will look at the rather popular Lenovo P780 device. For many users, after a year of use, the phone begins to perform worse. How does this manifest itself? When loading, the Lenovo P780 does not turn on or simply hangs at boot. Of course, this is not the only problem that users face. For example, due to carelessness, the phone is filled with water. What to do in this case? Let's figure it out.

The smartphone freezes and does not boot

If your phone stops turning on, then the best option to fix it is to reflash it. In order not to completely ruin your phone, it is recommended to take it to professionals who can bring your smartphone back to life in a few hours. This procedure costs from 500 rubles. Of course, this is a lot, but this way you will get a guarantee that it will work after flashing.

If you do not want to take the device to a service center, then you can try to do everything yourself. Let's find out how to do this.

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 is worth checking two other possible breakdowns - the battery and the 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.

Flashing the phone

Remove the cover from the smartphone and connect it to the computer via a USB port. On the laptop, open the device manager. Let's go back to the phone. Near the SIM card slot there is a Reseat button that must be pressed.

After completing the steps on your computer, your smartphone will appear in the device manager. Click on it and update the drivers (they can be downloaded or updated via the Internet).

If you have completed everything, then you can move on to the next step. Now you need to disconnect the phone from the computer and run the Flash Tool program.

To fix the problem that prevents your Lenovo P780 from turning on, you need to flash the device. First, in the program, click on the Scatter loading button. In the window that opens, select the location where the firmware is located. Click on the file and the utility opens it. All files must have a check mark. Check the box where it says DA DL All With Check Sum and click on the Upgrade button.

In a few minutes the program will prepare for firmware. We take the phone and connect it to the computer. When the device is identified, the firmware will be installed. After 10 minutes, the green circle should light up, indicating the successful completion of the process.

Turn off the phone and start it. If everything went well, the smartphone will boot and you can reinstall all applications.

Reset to factory settings

After the actions described above, several scenarios are possible. In addition to the usual reboot and turn on, the phone may turn off again or freeze on the screen saver. You shouldn’t be too upset about this, because the manipulations done helped ensure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor glitches that resolved themselves. If the violation in the operating system is much more serious (for example, after flashing firmware with errors), then you will have to perform a reset to factory settings. It is important to note: such actions delete all files from the device’s memory, including photos, videos and music.

1. Open Recovery as in the instructions discussed above.
2. Select the item “Wipe data/factory reset”..

The device should reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Lenovo P780 does not turn on after falling into water

If your phone has recently fallen into water, you need to quickly pull it out. Under no circumstances try to turn it on right away, as you will only reduce the chances of recovery. If it doesn't turn itself off, then do it yourself. After all, a short circuit will occur due to water, and you will have to change the memory, battery and other elements in the Lenovo P780. You must understand that through various USB ports, charging, and microphone holes, water will quickly reach significant parts, which, in turn, will disrupt the operation of the device.

There is no need to replace your Lenovo P780 until you are completely sure that the phone is not working. Remember that even if you wash your device in a washing machine, there is still a chance to save it. The main thing is to follow the instructions.

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 running 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.

Basic Rules

So, what should you do if your Lenovo P780 won't turn on after falling into water?

1. As we have already found out, we turn off the phone. If the device was connected to a charger, you should very carefully disconnect it from the network. Remember that water is a good conductor of electricity, so you may get an electric shock. In this case, it is better to disconnect the apartment or house from electricity and then take out and turn off the phone.
2. After you turn off the phone, you need to remove the battery. Then take paper towels and wipe the device dry. You also need to make sure that all additional devices are turned off (headphones, SIM card, memory card, etc.).
3. In order to completely get rid of water, you can try to disassemble the phone a little and wipe it from the inside. Remember that if even one drop remains inside, it will cause corrosion or short circuit.
4. You can dry your phone with a vacuum cleaner, but you don’t need to place the device too close to the hose. After 25 minutes of drying there will be no moisture left. This method is perfect if the smartphone is quickly taken out of the water. Do not use a hairdryer for this, as it can melt some elements with warm air, this will only cause harm.
5. Remaining moisture can be extracted using rice. If you leave your smartphone in a bowl of rice overnight, you can turn it on in the morning. Rice absorbs moisture well, but the gadget must be double-checked before turning it on.

6. Before turning it on, check all ports on your phone. If it looks completely dry and clean, you can turn on the device. You may experience strange sounds when you turn on your smartphone, which means that it is damaged. Also, if the phone does not start to turn on, but appears completely dry, then the Lenovo P780 battery may be damaged or discharged.
7. If complete drying does not help, then you should take the phone to a service center, where it will be checked for serviceability and, possibly, brought back to life. Of course, it will be quite expensive, but it is cheaper than buying a new smartphone.

Reasons for smartphone freezing

Not a single owner of the device faces such a problem as the Lenovo p780 phone does not turn on. When you turn it on, the screensaver just freezes, nothing happens and the smartphone does not boot. In this case, removing the battery and pressing the red “Reset” button does not help, with which you can hard reboot the device, that is, it is completely cleaned. The phone restarts and the screensaver freezes again.

In this state, the phone is called a “brick”. Most often, “bricking” occurs after the user tried to flash the kernel and gain root rights or, as it is also called, super user. Lenovo p780 does not turn on after flashing for the following reasons:

• While manipulating the phone, the user performed the actions incorrectly;
• Illiterate - crooked firmware that does not correspond to the version suitable for this model.
• Carrying out any actions when the battery is low. Before using your smartphone, be sure to carefully read the instructions. It is in it that it is written that any manipulations with a discharged battery cannot be performed.

Also, the phone can turn into a “brick” due to a technical breakdown of the processor, board or other important elements of the mobile device. A completely reasonable question arises about how to restore a Lenovo p780 brick.

Some smartphone owners decide to update the firmware themselves by reading the instructions or watching a video. They believe that with the help of such an operation the performance of the device will increase, and it will simply “fly”. But not everyone can do the firmware correctly on their own. This requires specific knowledge and skills. And if it is done incorrectly, it will turn out that the Lenovo p780 after the firmware is a brick. Therefore, experts do not advise opening the device without understanding, knowledge and skills. For this purpose, there are services staffed by professionals.

Conclusion

You need to approach device repair based on your problem. If it stops turning on itself, then you should try to reflash the device. All the necessary software is available on the manufacturer’s website Lenovo P780 4pda. If the phone stops turning on due to your negligence, then you need to follow the instructions above. There is no need to immediately think about replacing the device, since you can return it to its former life with your own efforts. Remember that all actions must be performed carefully so as not to further damage the device.

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.

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.

You can also try holding down the Home button, as well as the Power and Volume keys at the same time. Some Lenovo models, including the A 319, respond to such an impact and stop hanging.

The main advantage of these methods of solving the problem is the absence of any risk to the phone and the data stored on it. This is their main difference from the methods of bringing the phone back to life, which we will consider further.

How else can you fix the problem?

If the charging block, USB cable, connector of the Lenovo A6010 smartphone and its battery do not raise suspicions, you need to move on to software troubleshooting. Charging problems arise due to a malfunction in the Android operating system. The only way out of this situation is by resetting to factory settings:

1. Open your phone settings.
2. Go to the "Backup and Reset" section.
3. Click the "Reset Settings" button.

Performing this operation deletes all files from the device memory. To avoid losing important information, it is recommended to first make a backup copy through the settings.

Faulty touch screen

A faulty touchscreen, or touch screen, is one of the rarest reasons why Lenovo tablets do not turn on. As a rule, in such cases the device responds to the power button, but the owner can no longer see the result of the work.

The touch screen itself fails quite rarely. To do this, it is necessary to inflict strong mechanical damage. This problem cannot be solved at home. Only specialists from the service center can replace the matrix on the tablet.

Charger fault

To diagnose the functionality of the charger, just connect it to another device. If the charge indicator lights up, it means that the cause should not be looked for in this element.

If the other device does not respond to connection to the power supply, you need to replace one of two parts - the cable or the power supply. It happens that over time the plug changes shape, and in this case the problem will be obvious: being in the phone socket, it will wobble or will not be inserted at all. To replace it, it is best to contact a specialist, since doing it yourself is problematic.

If the unit is faulty, the indicator will not light up when connected to the network, and then you need to purchase a new one and leave the old cord. If the cable and the unit are the same, you will have to buy a completely new charger.

How to restore your device

To restore unsuccessful firmware, you need to prepare a laptop or PC, a USB cable, and take the following steps:

• You need to launch Device Manager. Press the red “Reset” button on your smartphone to restart the device. After this, a new device will appear in the manager. You need to right-click on it and update the drivers.

• Next, you need to select a manual search for drivers and find them after downloading them to your PC or laptop. They are usually located on the C drive. Click – “Install”.
• You should click on “Reset” again and a confirmation will appear in the task manager that they are installed. The smartphone can be disconnected from the computer.
• Now you need to install a special program called “FlashTool” and run it. All firmware files will appear on the screen; each of them should have a checkmark.
• Next, you need to click on the inscription “Press the Download button.”
• Using a USB cable, you need to connect your smartphone to your PC, having first removed the battery. As soon as it is determined, the firmware process will begin.
• The installation is complete when a green circle appears on the monitor.

For Lenovo p780, brick restoration has been completed. Now you can close the program on your PC, disconnect the device from the USB cable and check the operation of your smartphone. If the successive steps are performed correctly, the device should start, as the owner expected from it. That’s it – you can use your mobile device. But, if it does not turn on after flashing the Lenovo p780 firmware, it means that not everything was done correctly. In this case, it is better to contact a service center and entrust your smartphone to professionals.

Hardware problem

Nothing lasts forever, including technology, no matter how modern it is. If your Lenovo p780 does not turn on, or the Lenovo p780 does not turn on and the red indicator is on, and all of the above is after basic diagnostics and comparison of facts (there was no flooding, there was no fall either) - then the problem is in the hardware of your product, and here it is possible both memory and power controller, processor, and other components. Contact an authorized service center for high-quality replacement of spare parts.
