The Apple laptop won’t turn on, there is no response when turned on, the indicator light is on, and the screen has no display, what’s going on?

The Apple laptop does not turn on, there is no response when it is turned on, the indicator light is on, and there is no display on the screen. What's going on?

If the Apple laptop cannot be turned on, you can troubleshoot according to the following methods.

1) First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug in the power to see if it can turn on. If it still cannot turn on, continue with the following steps.

4) Cover the cover in reverse according to the disassembly method, install the battery, and turn on the power button to restart the phone. How to solve the problem that the laptop does not turn on, does not respond when turned on, has the indicator light on, and has no display on the screen?

This case is nothing to an experienced person. But for me, it was a great encouragement. Would love to share with newbies. I have repaired such a machine before, but it was done in a haphazard way (I put small squares of paper on the motherboard) and it has been more than half a year now.

Another one was collected for repair yesterday. There was plenty of time to research this time. I read through this forum first, and I probably know that this fault is related to the virtual soldering of the network card. ——I like this forum, it makes people improve, thank you. ——

Machine model: DELL D600

Symptom: No response when plugged in and turned on. The power indicator light is on, and other indicator lights flash weakly and quickly. After a few seconds all lights go out.

Maintenance process: Carefully disassemble the machine and clean the dust. Because the goal is very clear, we go straight to the topic. Press the network card chip directly with our hands, and the notebook can boot normally and run code. Therefore, the network card chip is soldered. It's normal after booting it up several times. troubleshooting. SONYC22H notebook does not turn on, no response when turned on, the indicator light is on, the screen has no display, the power-on self-test is stuck, what is the problem?

I don’t know much about notebooks. If it is a desktop computer, it should be due to loose memory. , you can try to remove the memory and use a rubber and gold finger to remove the graphics card. The laptop won’t turn on, the indicator light is on, and the screen is not on. What’s going on?

Lenovo laptop won’t turn on, and the instructions There are four reasons why the light is on and the screen is black:

The first reason: This is because the notebook's memory and graphics card are oxidized, resulting in poor contact with the memory slot or graphics card slot. The computer cannot be turned on and the screen is black. The probability of a black screen is 60%. The solution is: unplug the power, open the back cover of the notebook, and take out the memory card slot. If it is not The independent graphics card welded to the motherboard is also taken out of the card slot. Aim at the gold finger of the memory and graphics card (that is, the place with the copper piece) and rub it back and forth with an eraser at least 6 times, blow away the dust, and then insert it back , cover the back cover, and booting is usually OK.

The second reason is that the video memory of the notebook display card has a weak solder, the performance of the main chip is reduced, the display card BIOS is messed up, and there is a problem with the control power IC, all of which will cause the display card to fail to work properly. The display card is broken. Because the display card is broken, the screen will naturally be black. Solution: Jianyi repairs the display card, or replaces the display card.

The third reason: There is a fault in the startup circuit of the notebook motherboard, such as clock, reset, power supply, MOS tube, etc., which may cause failure to boot, black screen, I/O problems, etc. Unable to start the computer, black screen, wait, solution: send to after-sales service or repair shop to repair the motherboard.

The fourth reason is that the screen cable of the notebook is broken or has poor contact, resulting in no image signal transmission. When the screen displays, that is, a black screen, the solution is: ask the Weili Notebook person to reconnect the screen cable, or replace the screen cable.

I hope the above reply will be helpful to you.

Brother, coincidentally, my v3240 has had the same problem as you twice.

The following are some of my experiences in discovering problems and fixing them:

1. The computer could not be turned on at that time, and even the word "Compaq" did not appear. The hard drive and CD-ROM drive stopped spinning after a few spins, and the screen remained black;

2. I finished World of Warcraft in bed. I found it the next day;

3. I later took it to HP Gold Service Hongkou for repair (I was in Shanghai);

4. When I repaired it, they said it was the motherboard. A certain part is burned out (probably the seal is blocked while playing games);

5. When you go to HP Gold Medal for repair, you don’t need to bring any invoice or warranty form. Send it to the laptop engineer directly It was turned on and inspected;

6, and then it will take 7 working days to get it back, and they will return the motherboard to the factory;

Brother, go to Gold Medal Repair, service attitude Super good.

The following are the addresses and contact information of gold medal service providers in various places that I have posted. I hope it is useful to you, brother, I wish you good luck.

Hope you can reply to the above can be helpful to you. HP notebook V3432 has no response when starting up, the indicator light is on and the screen has no display, and there will be a sudden shutdown.

Does that mean it can still start?

Is there any movement from the hard disk and fan when the power is not reflected? ?

Is the screen not powered on?

If so, there may be a problem with the memory, or there may be a problem with the power management chip on the main board. Go to the after-sales service to check it again. Decide.
