1. Possible reasons why the machine cannot be turned on:

The reason is nothing more than two problems: hardware or software, and systems. If there is an external force, such as being dropped, pressed, flooded, overheated, etc., it must be a hardware problem.

2. The solution is as follows.

1.Check your phone's battery first. The reaction when the phone is turned on proves that the battery is still working, and in addition to the aging of the battery and water ingress, the battery problem can be ruled out.

If the battery is aging, you can try it with the same type of battery, and if it can be turned on normally, then replace it with a battery; If it is water, turn on the device when the water has not yet dried, it will cause a short circuit in the battery, and the phone will only run for a while, and the battery will be damaged due to a short circuit, you can wait for a day or two for the phone to completely dry and change the battery.

2.Check your phone screen. Under the destruction of external forces, the screen fails, especially some mobile phones themselves are soldered, which is particularly prone to "fake not booting" caused by the screen.

Although only a slight fall, but the mobile phone screen is no longer responsive due to the disconnection of the line, then you can tap the mobile phone, such as the screen will flash from time to time, proving the problem of a certain line, you can find the broken solder joint after disassembling the machine and re-weld it, or go to the maintenance point for maintenance. Especially when the phone vibrates and sounds normally when it is turned on, but the screen does not respond. This is especially the case for consideration.

3.Check if you can enter the recovery, consider flashing. Both of the above are hardware problems, but the phone can't be turned on completely normally, because there are many software or system problems.

If the phone is just stuck in the logo screen or can not be operated when booted into the interface, then check whether the phone can enter recovery, press and hold the power button + volume down key, if the phone enters the following screen, and can move the cursor by moving the volume + and - keys of the mobile phone, then the phone can be solved by flashing.

Dear users, hello!

It is recommended that you go to the BIOS and select Startup-Boot- to find your system hard disk, use Shift+ (plus key) to put it in the first place, and then F10 to save and exit. If you have any other questions, you are advised to call our service ****** for inquiries.

Coincidentally, mine is pressed F11, I checked, it seems to be set in the BIOS, and in the end I didn't get it done, so I had to send it for repair.

What is the boot sequence in your BIOS? Change it to boot from the hard disk to try it, if it doesn't work, is there a problem with the built-in keyboard you see? I guess there should be something stuck in some key.

Hello, you can go to our Dell technical forum to check the information, the content here is very comprehensive.

Meaning: Please install del and f2 into the udfi BIOS settings, that is to say, your computer is likely to be the first boot item is not an optical drive and a hard disk, but a floppy drive, so this dialog box appears, prompting you to enter the BIOS to set up, so that your first boot item becomes a disc drive or hard disk.

Solution steps: First of all, when this English appears on the screen, make sure that your computer has been connected to the keyboard, and then select the del key, different keyboards may be different in English, but they all start with del, press this key, if you miss it, you need to restart the computer and press this delete button.

The first is to click on the language in the top right corner and select Chinese. Then select Advanced Mode in the bottom left corner of the diagram.

Click on the boot option in the diagram, and then in the boot item 1, note that the hard disk selected here is sata this one.

Once set, press F10 on the keyboard to select OK or OK.

Restart, press the del key as soon as you restart, enter the BIOS, reload the factory default value of the BIOS, and then press F10 to save, after entering the system, you look at the time right, if the time is not right, the difference is far, that is the motherboard battery is out of power, replace a motherboard battery.

It is expected to be a BIOS setting problem, press the delete key when booting up, enter the BIOS If you will not be recommended to find someone who understands, there are many possible reasons, just set up the BIOS, if the situation is not good, it may be a motherboard problem.

There is also a possibility that the button battery of the motherboard is dead (old computer) EFI is a boot mode, have you plugged in the boot USB flash drive and did not pull it out, or adjusted the boot disk order?

This is the shortcut to boot into the BIOS.

The F12 key generally needs to be used with the FN key to take effect, and it is recommended to restart and hold FN+F12 at the same time to enter when this page appears.

I've also encountered this situation, nothing has been responded to, and after a minute you can enter the system, how to solve this? I hope the master helps.

Press the DEL key to enter the BIOS, then F10 save to exit.

"Advanced Settings" appears after pressing F10

After that there are three options.

The first one (the one I picked the first time) doesn't save the changes and pushes out 2, saves the changes and exits.

3.Advanced settings.

Select item 2.

It's a pity that I'm just a computer black, not even a little white, and I don't know a single English word, hahaha. I'm proud.

I'm also a little white.,But my method is to pull out the plug.,Reboot.,After the display of the button, you can enter the BIOS.,Then I selected F5.,Default the original settings.,It's good to boot.。 I don't know why, but that's how I opened it myself, and I hope it will be useful to you.

Like me, what should I do if I have this problem?

Power on 1Please check whether the battery is charged, or it is recommended to remove the battery.

Reinstall it and try to see if it can be turned on. Or remove the battery for 5 minutes and connect the charger for 30 minutes to try whether it can be turned on, if it still doesn't work, please plug it in and try whether it can be turned on. 2, or if possible, it is recommended to replace a battery, try it.

3. Still doesn't work, please (connect the charger) press and hold the power button and the volume button to try whether you can enter recovery mode, enter the back three clear data, and try whether to turn on the computer. 3.If it still doesn't work, go to a nearby repair point to have it tested.
