I have a problem in my DELL laptop. It is turning on and then the screen is going black.Than can not showing the windows logo. My laptop wasn't running well and suddenly this problem occurred. I turned off the laptop forcefully, and from then I am facing this problem. I have some important documents in my C drive where the windows is installed. Please help me and give me any solution from which I can turn my laptop properly again and do the works again properly. Thank you,
What happened before the laptop screen goes completely black? You mentioned something about forcefully restart. I would like to know was there any error code before the black screen?
Currently, when you plug the charger into the jack, can you see the light blinking or just everything remains calm and nothing can be heard from the fan or the hard drive?
If you can't and the warranty of your laptop has expired I suggest you to take out the hard drive and try to connect it to another computer through SATA-USB cable. If the HDD doesn't spin at all, anywhere, then it has failed mechanically and needs replacement.
If your hard drive spins up on a different computer and it is recognized there, but cannot power up on your laptop, then the problem is hiding probably in the power supply unit on your motherboard. You could bring your laptop to a technician to make a test of the power connector and/or the power jack center because they might have got damaged.
