Hello everyone. A friend of mine gave me her HP ze2000 to try and fix. It powers on but seems to be continuously rebooting. What happens is a few seconds after pushing the power button the scroll lock and caps lock LEDs flash simultaneously once every one or two seconds. This flashing just continues indefinitely. So far I've broken the computer down completely to just the motherboard and removed the RTC battery to reset the CMOS but the problem is still there. Most of the motherboards I've worked on had a thermal management IC that will shut the comp down if it overheats. Judging from past experience of working on another friend’s laptop, I think that IC might be bad and causing the continual reboot. Does anyone have a description or a list of the different motherboard components? It would save me a lot of effort. If I can't find detailed info on the motherboard components and layout, I'll have to track down datasheets on the parts one by one (very tedious). Anyway, if anyone has any info they think might be helpful or if you have any suggestions about how I should be attacking this problem, please let me know. Your help is greatly appreciated. Thanks.
