I have an Acer Travelmate and Windows 7 and have used it for years without. However, a problem that crops up a couple of times is that, while I am working, the screen will flicker and go dark. Actually, it's more of a light-ish dark. However, when I plug the computer into an external monitor or TV (via HDMI), the screen comes back on and works for a while. Also, if I hit fn+F4, and reboot, it temporarily solves the problem, but it recurs.
The last time this happened, I fixed it by doing a system restore to a previous version on windows 7. I tried that but the problem still persists.
Any suggestions would be appreciated.
