Screen went dark on T60

OK, so this is a very strange coincidence because I just ordered a new higher res screen for my T60 yesterday. But anyways, I came back to my laptop a while ago and the screen was very dark and difficult to see. I tried increasing the brightness, but to no avail. I checked the power management and everything was maxed out on the brightness settings. I rebooted the laptop and the same deal. So I powered it off and left it a while. I booted it back up and now its working.

Is this the screen going bad or something else? If it is going bad, it's pretty freaky timing.

 

probably either the inverter that is gone or the ccfl backlight that is gone. Talk about a timely purchase.

 

I've noticed the problem happens whenever I let the laptop sit for a while. I went in to my power management and saw that its set to dim to 30% after 20 minutes. But what I find really interesting is the brightness increase/decrease OSD ceases to come up after the dimming problem. I'm starting to think there's some buggy software behind this.

Just a few days ago I erased my Win7 32bit and installed Win7 64bit. Perhaps that has something to do with it?

 

what if you boot into your bios, does the screen stay on?

 

Hmmm... I think it was dim in the BIOS after the reboot, but I can't remember if it was dim after the full power off.

 

if it is dim in bios, then it is not a software problem, but rather a hardware problem.

 

I reloaded 32bit version of Windows 7 and the problem hasn't reoccurred. Maybe just coincidence? Very weird.
