I have a nearly 3 yr old IBM X41 laptop (1.6 GHz processor, 1 gig RAM) running WinXP Pro/SP2, Office 2003. It is in warranty until Aug 2008. So far this year, I've had the hard drive replaced and then a new motherboard (soley to fix the AC adapter connection). Since the motherboard replacement, my laptop freezes up -- can't shut down with the power button, can't reach Task Manager, must take it off AC power and remove battery...thereby crashing all open documents and killing my efficiency. This only happens at work (hospital) when I am working through the hospital network. Happens both on and off the docking station. Doesn't happen when I'm at home on wireless cable modem. My IT people are stumped -- they say there are no errors that appear in the event log when it crashes. I can't imagine it's a problem covered by the warranty. :4-dontkno Any ideas?
