It is recommended that you disconnect the power supply and battery in the case of not turning on, and press and hold the on/off key several times repeatedly, each time for about seconds!! If the fault is solved, it is recommended that you contact the service station to detect what is the reason for the failure to turn on, and we apologize for the inconvenience caused by the failure of the machine.

Lenovo dealer, service station inquiry:

In order to help you more conveniently, you can fill in the details below**, and the staff of Beijing headquarters will contact you, and we will do our best to help you.

If the laptop presses the power button and does not respond, and this situation occurs, you can try the following ways to solve it:

1. In this case, you can replace the power adapter to see if it is because the laptop is out of power and cannot be turned on, if there is electricity, it cannot be turned on, it is recommended to discharge electrostatic electricity.

Hello friends:

There are four reasons why the notebook computer can't turn on and the indicator light doesn't light up:

First of all, try the following operations: remove the battery and power adapter, press and hold the switch button for 30 seconds to discharge the static electricity, wait for about 15 minutes, and then connect the power adapter separately to power on; If it can't be turned on yet, it is the following reasons.

The first reason: This is the memory and graphics card of the notebook are oxidized, resulting in poor contact with the memory slot or graphics card slot, resulting in the inability to turn on, and the black screen, the probability of it appearing black screen accounts for 60%, processing method:

It is to remove the power supply, open the back cover of the notebook, take out the card slot of the memory, if it is not a separate graphics card soldered to the motherboard, also take out the card slot, align the part of the memory and the gold finger of the graphics card (that is, where there is a copper sheet) and rub it back and forth with an eraser, wait for the copper sheet to shine, and then blow the ash and then insert it back, cover the back cover, and the boot is generally OK.

The second reason: is that the video memory of the notebook graphics card is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, because the graphics card is broken, the screen will naturally be black, and the treatment method: Jianyi repairs the graphics card, or replaces the graphics card.

The third reason: the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to boot, black screen, i o problems, unable to start the computer, black screen, etc., treatment method: send after-sales or repair shop to repair the motherboard, the fourth reason is that the screen line of the notebook is broken or poorly contacted, resulting in no image signal transmitted to the screen display, that is, the black screen, treatment method: let the person who repairs the notebook replug the screen cable, Or replace the screen cable.

Hope it helps you and I wish you happiness

AnswerIf you encounter a situation where your laptop won't turn on (you can't turn it on without turning it on), the problem may be caused by static electricity on the motherboard. For this case, follow the steps below.

1) Please plug and unplug the adapter and battery. (If the battery is not removable, just plug and unplug the adapter).

2) Please press and hold the power button for about 10 seconds, this will clear the static electricity on the motherboard.

Laptops with tablets and CPU platforms such as Cherry Trail (e.g., T100, T101, etc.).

Press and hold the power button for 30 seconds to do EC RESET (the charging light turns off first and then on). *Note: Please plug in the power supply to operate a laptop (including SkyLake) with the CPU platform set to Skylake

Press and hold the power button for 12 seconds to do EC RESET (the charging light turns off first and then on). *Note: Please operate after plugging in the power supply.

3) After that, please plug the battery and adapter into the laptop and press the power button to power on.

Well, that's basically these 4 reasons, you can take a look.

So how do you say that? Because there are many reasons for him, and you can only take a look at this. Just try it out at once for each of your checks.

This check should be.

If the power light does not light up, it means that the power supply is faulty, and it can be repaired by replacing and repairing the power supply.

Is the battery charged? Turn on the power to see if the indicator light of the power supply is on, if there is still no response, you can disassemble the machine and wipe it with alcohol. Try it on the installation.

It may be that there is a problem with the motherboard of the notebook, and it is recommended to take it to the official store for overhaul to find out what is wrong so that it can be repaired.

It means that there is a problem with the power supply of this notebook, and it is recommended that you repair it.

The laptop doesn't respond when you press the power button, and the indicator light doesn't light up when the power is plugged in, what's going on? How to deal with it?

1. If the indicator light on the laptop power adapter is not lit, first of all, we check whether the power adapter is connected to the socket and whether there is electricity at the socket. We can try to plug and unplug it again, if the indicator light still does not light up, it should be that the power adapter is broken. 2. If the battery is used as the power supply, check whether the battery is installed correctly, whether the battery model is the original battery, whether the battery is fully charged, etc.

3. After eliminating the first two situations, it is possible that there is a problem with the power module of the notebook motherboard, please carefully check whether the DC board is normal. 4. You can use a multimeter to measure whether the output voltage of the power box is normal, whether the socket on the laptop is loose, whether the switch is effective, or whether the light is not lit when it is turned on, if so, it is probably because the lamp is aging. 5. If the power indicator of the notebook is not lit, first remove the battery to see if it can start the notebook when the power is on, if it can, then the LED power indicator is broken.

If it doesn't work, it may be that your computer's adapter is broken. Try to see if you can charge the battery, if you can, then the LED power indicator is broken.
