The laptop graphics card is broken and won t turn on

Your machine model or graphics card model, this repair technology is very related, and the graphics card chip must be replaced with an improved graphics card if it is a graphics card door, otherwise it will be a waste of money. Next time, find someone to fix on the spot, there must be something wrong with the technology so fast.

BGA is not easy to replace, if a motherboard has been replaced with a graphics card, bridge, the performance of the motherboard may become unstable, especially the level of general maintenance institutions to replace BGA is not necessarily enough. It is recommended to find a repair point to take a look again, it is best to warrant it, and it is better to change a motherboard if it doesn't work.

If it breaks down again in less than a week, you should go to the maintenance office at that time to repair it for free, and they need to be insured for at least 1 month after repair.

As for desoldering, it may be that the soldering after desoldering is not successful, and the problem is not completely solved.

If you don't understand something, please ask, it helps, thank you

Of course, the book of a single graphics card can't be turned on! And the machine with dual graphics cards can be turned on.,Of course, if the core graphics are broken, maybe you will also be broken.,Then it can't be turned on.。

If the graphics card is broken, it is better to replace the board, how expensive it will be to repair it, and it will be broken again after a short time.

I suggest you change a board so as not to get into trouble.

It depends. If the CPU has an integrated graphics card, it can boot normally; If the CPU does not have an integrated graphics card, it will not boot properly. The discrete graphics card is a separate circuit board for the graphics chip, video memory and related circuits, which are self-contained and exist as an independent board, which occupies the expansion slot of the motherboard and can be upgraded according to needs.

The graphics card is not broken, but the fault analysis and elimination of the machine cannot be turned on are as follows:

1.Causes of computer dust: The computer has too much dust, which causes the computer to have abnormal heat dissipation and cannot be turned on normally. Disassemble the host and clean the ash, blow the ash with a hair dryer or hair dryer, remove the graphics card and memory stick, wipe the gold finger with an eraser, reinstall it and restart it.

2.Faulty monitor or cable: The best way to do this is to use another cable to connect another working monitor to troubleshoot.

3.Graphics card or graphics card contact failure: After removing the connection cable, connect to the onboard graphics card of the computer, if the display is on, it may be a contact fault of the graphics card or graphics card, it is recommended to remove the graphics card, wipe the gold finger of the graphics card with an eraser, and then plug it back in and boot it again.

4.Problems with memory modules: If the memory module is not plugged in or malfunctioning, also remove the memory module or change it, wipe the gold finger of the memory module with an eraser, and then plug it back in and boot it again.

Note: If conditions permit, you can use the diagnostic card, which can be directly inserted into the motherboard of the computer host, and the fault displayed by the diagnostic card can be specifically instructed which computer ** hardware has a problem, and the problem can be quickly solved. If not, you can only troubleshoot them one by one.
