I purchased my XPS L701X (Windows 7 Pro x64, i7 Q840@1.87GHz 12GB ram, Nvidia Geforce gt 445m) in January and since about March I've had this persistent problem of my monitor screen shutting off. I've been on the phone with various Dell technicians and no one has been able to help solve this issue. Every time I've been told to run the start-up systems diagnostic and have been told that this is not a hardware problem. I'm tired of reinstalling my various software programs and clean-installing windows to no avail. I've done so at least 4 times and yet the problem still persists.
My problem: I updated to Firefox 4 and noticed that when using the browser, my monitor screen would go black (like it was off) while the computer still remained on. I would have to force shutdown by pressing the power button. I was able to solve this issue by reverting to Firefox 3.6. I thought this was the end of the problem but it still continues.
The monitor screen continues to go black when I do the following:
What I've done:
Last night when my monitor blacked out, I left the computer on rather than forcing shut down. I was curious as to whether it would go into sleep mode and I could get it to turn back on the same way I would normally pull my computer out of sleep. However, instead, the computer remained on and running until it ran out of battery.
If anyone can offer any solutions on how to address this issue, I would really appreciate it.
