GX640 possibly stuck in sleep mode?

I got a GX640 back in late April. Since then, I've had to RMA it twice due to display issues. I got it back a few days ago, and it again seems to be having problems. This time, though, I think it may be stuck in sleep mode. I flashed the BIOS and VBIOS and installed Catalyst 10.7 after I got it back the second time, and since it was okay for a couple days after that, I don't think I bricked it. Currently, if I turn it on the display doesn't power up, and the moon LED on the front turns on a solid blue.

If I am indeed stuck in sleep mode, anyone know how to wake it up? I've tried leaving it unplugged with the battery out, and that hasn't made a difference. If that isn't the problem, any idea what might be wrong?

Thanks in advance for any help.

 

Try draining the battery out first. If that does not work report back

 

When the laptop is on, the "moon" LED really stays on. It blinks when put to sleep. Are you sure you flashed the vbios properly? The stock vbios had an issue wherein shutting down the laptop in battery mode causes the laptop screen to turn black after the starting windows screen when you next boot up. The only fix is to enter safe mode, uninstall the video drivers via device manager and restart. Then reinstall the drivers. The vbios update fixed this.

 

I had the same symptoms after a failed vBios flash. I bricked my card. Happily enough got it replaced in warranty service ^^.
For me it was like: I press the power button, HDD spins up, HDD symbol lights for about 2-3 secs, then gets down, moon symbol is on, battery charge indicator also works correctly, even caps lock and num lock works, touch panel button works (wireless, bluetooth). However, nothing is visible on screen.

Or if you are lucky, a "Blind flash" can help you out.

 

Draining the battery didn't help. Left it on before I went to work, came back, plugged it back in, nothing's changed.

I definitely thought the vBIOS flash had succeeded, because I did it on Friday, had it on, sleeping, and hibernating a couple different times over the next three days, and even hibernated it once on battery Monday night. That said, my symptoms definitely seem to match what Molius described.

*sigh*

Any other suggestions? If not, guess I'll just try RMAing it. Again.

 

I had this problem on my GX 730, turned out my Mobo was fried. Got it replaced and it booted up nicely... although, vista and or my computer has been freezing like a b**** lately
