Ok, I've been working on this problem for at least 3 weeks now. My laptop, which was built by a compaly in Fargo N.D. (bytespeed) is acting really strange. When running off of the battery, everything is just fine, no problems whatsoever. But, then when I plug in the power adapter, it acts like it's possessed, most of the time not getting past the BIOS in post, then the power cycles and it starts all over again. Sometimes it will make it as far as the login screen for WIN2k, but then it starts cycling again. So far I've WIPE'd the harddrive, flashed he BIOS and re-installed the OS. Now I'm at a complete loss. All of the fans are working like normal, so I'm pretty sure it's not a heat issue. Any help on this will be GREATly appreciated.
