I have a laptop whose screen stopped working after being in sleep mode. It worked on an external monitor via display port but I made the mistake of switching to the microsoft basic display adapter while trying to fix the issue. It now doesn't work on the external monitor either...

I have tried a hard reset with the battery out, reseating the RAM, reset the bios and CMOS. I can access the shared drives on the laptop so have recovered docs, etc but there is no remote control set up so can't do anything else. It does have a VGA port but i don't have a cable so haven't been able to test that yet.

I am happy to remove the HDD, format it and then try to reinstall windows from USB or something like that but if there are more options to try I'd like to. It could also just be that the screen is poked I guess lol.

Any ideas?

Do you get any image on the screen like a logo and/or can you get into the bios?

You'll be able to see the BIOS with a DisplayPort monitor connected. In any case, have a go at logging in blind, wait a minite, and use the WIN-P to try and blindly set it back to Clone Displays or similar so even if the internal display is faulty you can use an external screen.

Hopefully a Windows reinstall helps, but it sounds like a hardware fault if you can't see the BIOS screen.

Is it a case of the backlight giving up? If you shine a light on the screen from various angles while the laptop is on, you might be able to see something, albeit very dimly. Might be enough to help you log on and change the display settings.

This ended up being the case :/ Thanks for the tip. Now time to get back in there and see if I can fix it. I don't like my chances but gotta try right?
