When I have problems in study and work, I want to open the computer to check the data, but I find that the computer doesn't respond when I turn on the computer. What's the matter? Here are the solutions I sorted out for you. I hope I can help you!
Solution of no response when starting notebook computer
Step 1: first, analyze according to the specific situation. If there is no power response directly, check whether there are problems such as power supply, poor contact and hardware, and go to step 2. If it is unable to enter the system, it may be an operating system or software problem, and go to step 3.
Step 2: check whether there is a power problem. First, check whether the power is not plugged in properly or there is a problem with the plug. If the battery is used, plug in the power and try again. You can go to a friend or go to a computer repair shop or sales shop to find a power supply of the same model and try it. After re plugging in the power, press the start button again. If it still can't be turned on, press it for a while. If someone else's power supply can be turned on, there is a problem with the power supply. If it is proved that there is no problem with the power supply, it may be due to the hardware. Go to step 5.
Step 3: enter the last correct configuration for adjustment, turn on and long press F8 to enter the advanced options page, select "last correct configuration", and then enter. If you can enter the system, it may be caused by virus infection, incompatibility between hardware driver and system, operating system, etc. After entering the system, run the anti-virus software to check and kill the virus. If there is a virus, restart the computer after anti-virus. If it is not normal, it may be caused by the incompatibility between the device driver and the program. Delete the driver such as graphics card and network card, restart it after deleting the driver. If there is still a problem, go to the next step.
Step 4: repair and install or reinstall the system, set "CD-ROM drive as the first boot device" in BIOS, then insert the system disk, and press R key to "repair and install". If the fault persists, just at the beginning of entering the system, select "one click gost restore the system" or use the system disk to reinstall the system.
