My sister has a Dell laptop with Vista OS. The screen suddenly went almost totally black yesterday for a while. Moved it and rebooted to see what would happen. It booted up fine and worked most of the day. Then it went dark again. Have tried booting it, moving & cursing it to no avail. It does seem to be working okay, just can't see it. Does she have a big problem? Any ideas of what can be wrong and/or how to repair it?
Thanks for any input.
