It is recommended to send it for repair.

The battery is generally replaced for one year, and if the screen flashes, go to replace one, and then repair it.

You make a system first, wow. It may be caused by software conflicts or viruses.

If it doesn't work, it is estimated that it is caused by hardware such as the graphics card, CPU fan, and high temperature. I took it to repair.

Notebooks you have to buy in a serious place. Don't buy refurbished. Fake. js especially a lot now.

What brand of notebook. You can fix it if you buy a computer!

1. The reason why the laptop boots up with a black screen.

There are many reasons why the note is black, and the common reasons for the black screen are:

1. Poor contact of display data line BAI;

2. Poor contact of the graphics card or;

3. Poor CPU contact and overheating;

4. Poor contact of memory modules;

5. Poor power supply performance;

6. The machine is infected with CIH virus, and the BIOS is destructively refreshed or;

2. How to fix the black screen of the laptop.

1. The boot display screen is black, only the indicator light is on, and the host does not have any reaction. I can't feel the fan spinning behind my hand behind the main unit. None of the voltages are measured. Remove it and find that the power adjustment tube is broken, and replace it with normal.

2. The power supply and CPU fan are normal, but the screen has no reflection, and there is no self-test sound. This machine adopts SLOT1 structure, and the CPU is easy to contact poorly, so it is sent to the after-sales service for inspection and maintenance.

3. Do not self-check when you turn on the machine, and check that the power supply of the noisy liquid is normal. Using the minimal system method, the machine can start normally when the optical drive is unplugged. Then install the fault recurrence. It means that there is a problem with the optical drive, and the machine cannot be started. It should be sent to the after-sales service immediately for disposal.

If the screen of the laptop is turned on, it may be that the computer system has been damaged or poisoned, the memory module is loose, and the electrical chip is aging.

If the computer system is damaged or poisoned, you can try unplugging the power and battery, and then restart it to see if the boot is normal. If the memory module is loose or there is a problem with the memory module itself, you can disassemble the back cover of the laptop, reinsert or replace the memory module.

Tong Brigade; You can reconnect to the power supply and wait for the energy voltage to stabilize before using it.

The failure of the display switch circuit is the main cause of the black screen failure of the monitor, and the computer can be sent to a repair shop for repair.
