Lenovo p780 does not turn on, red light is on

Many owners of a Lenovo P780 smartphone running Android are faced with problems in which the phone does not turn on. This happens both after certain actions and during normal operation of the device. During our article, we will talk about the main causes of the problem and several troubleshooting methods.

Lenovo P780 won't turn on

This article is aimed primarily at users using Lenovo IdeaPhone P780 with official firmware without any third-party modifications. If you are not one of these people, our methods may not be useful to you. It is also worth considering that there are many reasons, including mechanical damage, that can affect the inclusion of a smartphone, but require an individual approach.

Method 1: Charging the battery

The most obvious reason for the Lenovo P780 not responding to pressing the power button is low or no battery charge. Unfortunately, if the battery is completely discharged, you won’t be able to check this, but even so, you can connect the charger and wait a while. Depending on the degree of discharge, it will take up to several hours.

If there is no reaction to charging, you should check the battery for functionality using a multimeter or another similar smartphone. Alternatively, you can replace the battery with a working one and try turning on the device.

If the described steps do not bring results, you still need to make sure that the battery is working, since for further actions the phone must be charged to the maximum.

Method 2: Reset settings

By default, the Lenovo P780 phone allows you to clear the internal memory through the recovery menu without any hassle, thereby deleting all user files and resetting the settings. Usually this will be enough to solve the inclusion difficulties. However, if the smartphone boot process does not start at all, the only option is to flash the firmware from the following method.

On the phone body, simultaneously hold down the volume up and down buttons. Add to this combination pressing the power button and hold the device in this state until vibration and the Lenovo logo appear.

Once on the start page of the recovery menu, find and click on the line “Wipe data/factory reset”. To navigate, use the volume buttons and the power button to select sections.

At the next stage, use the “Yes – delete all user data” item in the same way and wait until formatting is completed. The deletion status will be visible at the bottom of the screen under the Android logo.

When you return to the home screen, select "Reboot system". Ideally, after this the smartphone should boot without problems.

There is no point in describing the following steps, since if successful, the phone will be reset to its factory state. If this does not happen, you can move on to the last method.

Method 3: Phone firmware

Most often, due to an unsuccessful attempt to update the firmware, and sometimes without any preliminary manipulations, the software on the Lenovo P780 becomes unusable. Here, as a rule, the actions from the previous section of the article will not bring any result, since the software responsible for loading Android is damaged on the device. To troubleshoot problems, you will have to replace the firmware using official Lenovo tools.

You can familiarize yourself in detail with the flashing procedure at the link provided above, where methods for all possible options were covered. Please note that in order to flash the device’s firmware in order to fix the problem in question, the computer must easily detect the phone’s USB software to access the internal memory. If this does not happen, most likely the problem is with the battery or mechanical damage.

Battery won't charge

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.

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.

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.

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:

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

Option #2. Hard Reset

If a simple reboot does not help, and Lenovo a319 still does not turn on or does not load beyond the splash screen, you need to resort to more radical measures. The best option is to reset all settings, or, in other words, Hard Reset the phone. This is quite simple to do - you just need to go into Recovery mode.

To make it easier for you to complete this procedure, we offer a simple algorithm:

Turn off the phone by holding down the power key for 10-15 seconds.
Press the Power and Volume Down keys at the same time. You can do this with one hand, but we recommend using both. There have been cases when, through negligence, people dropped the device while trying to press both buttons with the fingers of one hand.
We wait for the manufacturer’s logo to appear, and after a few seconds we find ourselves in Recovery mode.
Using the volume down and up buttons, select the “Wipe Data” item. It involves deleting all data and settings from the phone. This way, whatever the software problem is, you will most likely fix it.
The system will ask if you really agree to delete all data. Confirm your actions and wait about a minute. Next, agree to reboot the device and wait for the updated software to download.

If all systems start normally and the phone functions the same as it did before the problems arose, then congratulations - you have found a relatively simple and painless way to resolve the issue. If the phone still does not turn on, or the download does not go beyond the screen saver, you can only resort to the third method.

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.

What can be done

First of all, you need to turn the laptop on and off several times, the system can recover without repair;
Press the F8 key and, without releasing it, wait until a special window opens with additional boot options, designated as Advanced Boot Options;
Select the item using the arrows on the keyboard - troubleshooting computer problems, like Repair Your Computer. This option can only be used with a backup copy of the operating system in a hidden partition on the HDD. The latest models definitely have this function. Various windows will open containing information on how to restore the system startup.
There may be a problem in the hard drive - drive C, which needs to be cleaned. To do this, you need to enter the system in safe mode and move some files to drive D. This action will make it easier to load data and free up space for the normal functioning of the system;
In Safe Mode, you can roll back to a reliable restore point. After this, you need to run the antivirus.

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.

Flashing Lenovo p780

Lenovo is a major supplier of modern gadgets. With prolonged use of this technique, various shortcomings may appear. Unfortunately, no one is immune from this. The competent specialists of our Lenovo phone repair service center will help you fix any problem.

You may be able to fix the simplest problems yourself.

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.

Battery and/or charger

What to do if Lenovo p780 turns off and won’t turn on? If your charger and charging connector are in good working order and have no mechanical damage, inspect the battery itself. It shouldn't be swollen. If everything is normal, then there is such a thing as a deep discharge of the battery. Modern phones that are in long-term use are not recommended to be completely discharged - this leads to a deep discharge of the battery and it takes a lot of time to restore their energy capacity. So plug your phone into charge and wait a few hours.

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.

Moisture ingress

A very common reason that the Lenovo p780 does not turn on, and may glow red, for example, is moisture getting into the device itself. Here are the recommendations: Turn off your phone. Under no circumstances should you turn it on to avoid a short circuit. You need to remove the battery and try to dry the product.

Do not use a hair dryer for this, as hot air may cause internal parts to melt. Experts suggest using a regular household vacuum cleaner for at least 25 minutes. Just don't lean it too close to avoid damaging your device.

To eliminate residual moisture, there is another simple and affordable way - place the device in a container with rice for several hours. Rice absorbs moisture very well.

If, after all the steps taken, the phone still does not turn on after getting wet, then oxidation and contact closure have probably already occurred and only a technician can restore it.

Software failure

If your phone does not boot or freezes, you can try to solve the problem by resetting it to factory settings. In this case, all information in it will be deleted.

Due to a failure, it is possible that your Lenovo p780 does not turn on after flashing the firmware. For example, during the update, the phone was discharged or there was no contact in connecting to the PC via a USB cable while flashing the firmware using the FlashTool program. It is recommended to reflash the device again.

In order to do a Reset (reset to factory settings), you can press and hold the power and volume buttons simultaneously. Or next to the SIM card slot there is the Reset button itself, which you need to press. If this does not help, then try to reflash the product. It is better to turn to professionals, but if you want to do it yourself, then below are brief instructions.

To flash your Lenovo p780 phone yourself, you need to install the FlashTool program on your computer with a set of drivers that optimize the interaction between the device and the PC. Prepare a working USB cable. The phone itself must be turned off, with the battery removed, which must have at least 50% charge.

Next, connect your phone via the cord and reset the settings. Your phone is detected in the device manager - by clicking on it with the cursor, we start automatic downloading or updating of drivers.

You need to disconnect the phone and launch FlashTool. In the program that opens, you need to find the firmware itself. To do this, click Scatter loading and select Scatter-file. The DA DL All With Check Sum checkbox is required. Then you need to click Upgrade.

Connect your phone again and the firmware installation will begin automatically. Wait for the process to complete. After turning off your phone, start setting it up. If everything went well, the phone will start without problems.

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.

Mechanical damage

If your phone does not turn on after any mechanical impact, such as a shock, fall, excessive pressure, etc., then you cannot do without the help of a specialist. The cable may need to be corrected. To do this, the phone must be disassembled and it is better to entrust this 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.

Option #3. Flashing

The third method is the most radical, but it is definitely worth using if the phone suddenly turns off, does not turn on, or freezes. We act according to simple logic - if the system cannot be restored, then it should be replaced. In the case of computers and laptops, we usually reinstall the operating system, and for phones, changing the firmware works.

First, download the firmware to your computer, and then transfer it to the memory card installed in the phone. The firmware is downloaded as an archive, and there is no need to extract files from it. We throw it on the map exactly in this form.

Now we go to Recovery in exactly the same way as in the previous case, that is, by holding down the power and volume buttons. If there are installation files on the memory card, the system will recognize them and offer you the following option: install zip from sdcard. This is exactly what we need if the phone turns off and we need to change the firmware. We confirm the actions by starting to download the file.

Typically flashing takes a few minutes. Don't be alarmed if your phone turns off during this process - this is quite normal. It can reboot, and repeatedly. And this is not a cause for concern.

After several reboots, the system will turn on, and, most likely, you will no longer see freezes and slowdowns. This means that the problem is a thing of the past, and now you know how to turn on a phone that has started to slow down or does not turn on.

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.
