Having problems with your Acer Extensa 5420-5687 Notebook ?
Acer extensa 5420 black screen turned on but cant hear or nothing ok i turn on the laptop and its working fine and then just it goes to a black screen i tried to turn it off but it wont go off the screen now its just on a black screen with the button on! WHAT DO I DO??
I found that the IRA causes the black screen while installing drivers for it during the installation of Windows 7. You can uninstall the drivers for the IRA but when you boot the machine, it will find it and reinstall. I went to the bios and disabled it there. Solved the problem. No more black screen. Hope this helps.
If you have another monitor you can hook that up to the blue connector( VGA) This is usually on the side or on the back. If you get a picture then your internal video might be bad.
