Yesterday at 6:30 A.M. I tried to boot up my laptop and all I was greeted to was a black screen. I don't know the model number of my laptop, but I know it is a HP Elitebook and it looks similar to this:
. The lights on the bottom and top light up when I try to boot up, but it stays on a black screen and doesn't go to the user log-in screen. My laptop is a used Windows 7 laptop running Windows 10, so maybe that is the problem? Can anyone help me?
If you are not getting any signal on the screen, most probably this is not a Windows related issue. I would suggest you to shut down the PC, disconnect power cable and battery and hold down the power button for 20 seconds. Reconnect the power cable and try to boot. If there is no change, you may be facing a power related issue. If the laptop is under warranty, I would suggest you to call the seller.
