Instructions
Step 1
If your mobile computer does not turn on, check the voltage at the power supply connector. Try connecting the battery to the laptop if it has been disconnected. Try turning on your computer again. Make sure the power button is working properly.
Step 2
Much more often, the following picture can be observed: the mobile computer turns on, but the download does not proceed as expected. Usually this malfunction is accompanied by various text messages or blue screens. Carefully study the text of the error and find its description on the website of the manufacturer of this laptop model.
Step 3
Try replacing the RAM cards. If that doesn't work and the laptop still won't boot, the problem is most likely with the video card, processor, or motherboard. Find out the type of video adapter you are using.
Step 4
If your laptop has a full-fledged discrete graphics card, replace it with a similar model. If you are dealing with an integrated video chip, contact the service center for troubleshooting.
Step 5
If the image on the laptop disappears, then there is a problem with the video card or display. Sometimes the cause of this malfunction may be a loop going to the matrix. Try closing the cover of the mobile computer and reopening it. Turn on the laptop several times, constantly changing the display position.
Step 6
Press lightly on the die. If you see streaks near the point of pressing, then the problem is in the cable or video card. Reset BIOS menu options. Try turning on the mobile computer again.
Step 7
If some devices on your laptop are not working, try updating your drivers. Download the necessary files from the official website of the company that developed this laptop. Keep in mind that most of the time it is the drivers or the operating system that is causing the problem.
