My laptop has a black screen after turning it on, and I have been changing the graphics card for 10

It seems that the landlord's is a unique graphics card,In fact, it is not technically difficult to change the graphics card,It's because the installation is more complicated, such as IBM,It's very responsible to change,Something else is very simple,This problem of replacing your parts is a very realistic problem,This kind of problem will not occur in the after-sales service of large manufacturers,If you are complained,His job is over,It's also difficult to find a job,If it's your own search,It's not sure,But it's not very easy to accompany a part similar to your model., It is recommended that the landlord go to a relatively large regular maintenance station to repair it. Safe, it may be a little slow, but rest assured. I hope the landlord will solve the problem as soon as possible.

If you meet a profiteer, you will be warned back, and if you can't fix it, you will sue ......

I don't know what concept you mean by "black screen". There is no screen display, if there is no large number is a problem with the graphics card. Try changing your graphics card or fixing it.

1. You can directly plug it into the monitor to see the original configuration, and the external output will not be affected.

2 is the screen, it stands to reason that the screen is good You just mentioned that there is a problem with the graphics card You can ask him to test the screen on the spot to show you Then the screen is not lit is the screen is blacked If the screen can be lit, it is OK The screen is crushed Otherwise, it is difficult to have a problem

3 Ask him to disassemble the computer and show you the accessories inside, the old and the new can be distinguished, and you can also look at the model of the hardware (this is a bit difficult).

Can the graphics card of the laptop also be changed? Let me tell you, the vast majority of notebook graphics cards are soldered to the motherboard (those high-end notebooks are more than 10,000 yuan, and there are desktops that can be replaced), and if you want to change the graphics card, you have to change it with the motherboard. The cost is better to add some money to buy a new one (if you want to replace it, you can only replace it with the same model of motherboard, and replace it with something else, which is very likely to lead to slow boot, poor compatibility, unstable system operation, and frequent crashes).

What I want to ask is "My laptop has a black screen after changing the screen" Have you changed the LCD of your laptop ? Or do you mean change the wallpaper when you change the screen?

And the cost of this maintenance How much did it cost 500 to 2000 If the repair shop is reputable, it should be replaced (as for what you said about using Master Lu to detect or that graphics card, this is normal, because the replacement is still the original motherboard of the same model, so the graphics card is also the original model).

If you really want to know, you can put the model of your computer, such as how much is the motherboard of the xx notebook, you ask, and compare it with the maintenance cost you spent, and look at the difference, the difference is not big.

If you have been deceived, please also want to open some After all, it has been repaired, and then it is meaningless to pursue it, and next time you go to a repair shop that talks about reputation.

1. Check whether the monitor cable is firmly and reliably inserted into the host interface, and then check whether the contact between the graphics card and the IO slot of the motherboard is good.

2. If the computer can start normally if you change to another monitor, then the original monitor may be damaged, please replace it with a new monitor.

3. Check whether the CPU fan is running.

4. You can remove all components except CPU, graphics card, and memory stick, and then start the computer; If there is a fault in the memory, there should be an alarm sound; If there is no alarm sound, then re-detect after changing the CPU; If the computer screen is still black, it is recommended to replace the motherboard.

5. Whether the system installs software and update patches, if so, please uninstall the update file.

6. After installing the software, the computer restarts the update and causes a black screen, just wait for the update to complete.

7. You can enter the safe mode to repair the computer, if you can't enter the safe mode, please reinstall the system.
