I recently replaced the CPU fan in my laptop. Now when it boots the screen appears long enough for me to type in my Windows password & then it goes dark. If I look very closely, the display is still there, it's just so dark that it's barely visible.
I have checked all my brightness & power settings. The brightness is set to its highest setting & there are no power settings that are shutting anything down.
I have an external monitor connected now & can use the laptop for hours this way, so nothing is wrong with anything else. When I use F4 to switch back & forth between displays, the laptop screen will actually display for a few seconds & then go dark again.
I checked & all of my drivers are up to date.
Any help appreciated. Thanks!
