are you able to enter the bios without the external monitor? what is the full model number of the laptop
I have an older laptop that I would like to continue to use and not buy a new one. A while ago the screen stopped working however today I got it working. What I did was I was able to connect the laptop to an external monitor. Then I uninstalled the display adapter from the device manager list, the computer restarted and then the laptop screen turned on and worked normally without the external monitor and I used it. Later when I tried to turn the laptop back on it was having the same black screen problem. I tried to repeat the same process by using the external monitor and uninstalling the display adapter but no luck.
