I'm having a problem with my beloved T60p (4:3)--right now, it's not powering on correctly and does not display the ThinkPad splash right when it starts up. The power, battery, AC indicators are lit but the screen stays black and doesn't do anything. If there is a disc in the optical drive, it'll spin up and spin down. Last night, the laptop was working normally but all of a sudden the screen went black, so I turned it off and turned it back on, but it didn't start (the same as it's doing now). I thought it might be overheating so I waited a bit and tried turning it on again, and it booted into Windows but less than 30 minutes later the screen went black again, and now it hasn't worked since. It might be worthwhile to note that this scenario has happened to me before in the past (maybe within the past 2-3 months) but after waiting awhile it always ended up working again.
Since the screen went black, I thought it might be the LCD, so I hooked up the VGA to an external monitor and did Fn+F7, but it didn't do anything (and I'm not sure if you can switch to an external output while it's booting?). After doing some research it looks like it could be the CPU, or the entire motherboard? I also pulled my RAM and it did give me the intermittent 3 beeps, and when I put the RAM back in there were no beeps but still no POST.
Do you guys have any thoughts on what might be causing this? Maybe it'll work for a little tomorrow, I managed to get PC Doctor on a CD and will try to run some diagnostics if I can, but I appreciate any inputs! Thanks
