    Just bought an HP ProBook 4421s and did a clean format to XP.

    Issue: during daily usage, the fan can suddenly goes very high out of nowhere and at the same time the system freezes, have to power off manually to shut it down.
    The very high spinning sound makes it seems like it's working in a very maximum force. I can be sure it's not in high temp and I'm not doing anything with high processes. The freezing is random, sometimes only minutes after I turn it on, sometimes half day, sometimes when multi-tasking, sometimes just leave it on doing nothing, ...

    This notebook is for office purposes. Strange thing is, it always only occurs when I use it in my office, but when I try it at home, no such issue happening. I'm at home now, been leaving the notebook on for almost a day and nothing happened until now.

    Do you guys think it might has something to do with power jack in my office? Anything power-related?
    I suspect there must be something to do with power, since it's only happening at my office and not in my home.

    I have tried several possible ways, but to no avail.
    Clean reformat, update every drivers from HP website, down/upgrade BIOS, running with/without battery, etc...

    Similar problem plagued the first batch of 8740w machines. It's a hardware issue with a hardware fix. You should contact HP and request a resolution (replacement).
