I recently had this issue as well on my 770T NAS box. I ordered some video cards and once I replaced the video card, it boots in the time it should every time. Before that, I tried memtest, checking the CPU was seated properly and not running hot, checked temps with a IR thingy of both bridge chips and several other things. I also replaced the battery and reset the settings to defaults and then adjusted to my way. The only thing that changed the long POST time, changing the video card. I might add, I've booted that thing a lot since I changed the video card and it boots right up each time. If you have a built in video system, you stuck. The only option I can think of, clean the heat sink/cooler for the CPU and such and see if that helps any. If you doing a cold start, couldn't imagine heat being a issue tho. If you have a video card that can be changed, might want to try that. I've never seen a laptop with one of those tho. I hope someone else has a better suggestion. Dale :-) :-)
