Recently acquired a refurb 6910p (incl docking station EN489AA) from HP. Great laptop overall, but I had these mysterious freezes once or twice a day. Had to hard reboot when it happened.
Figured out (from proc explorer) that the freezes were spikes in the HW Interrupts. Updated all drivers, BIOS, etc... disabled a few devices. no help.
Finally figured out that hibernating on docking station followed by undocking was definitely a problem. So I stopped doing that.
Now, I usally go standby -> undock (seems to be okay). But last night I did an undock while laptop was on. Problem re-occurred.
NOTE: UNDOCK = push blue button on docking station. There is no "Eject PC" in my Start menu. Niether are there 2 hardware profiles as many web-postings claim there should be.
Q: Doesn't hot-dock support mean that I should be able to undock while on standby or "ON"? What am I doing wrong? Is this problem an indicator of a separate HW issue?
I need to decide fast if I want to ship it back to HP for a full refund (10 days left where i can do that). I'm reluctant to send it back if this is a resolvable issue. I need the hot-dock to work.
If this is a HW issue, I want to send it back.
