Glenn,

My laptop is _never_ off. It's a real work horse (I do almost all of my development work on it). Every night there are several cron jobs that do various things from backing up to testing code. So there is really never a down time. Other than the intermittent power issue it has no problems!

My case is much more similar to kf_man's problem in that it does not happen very often. It also never happens while the power supply is plugged in and everything is happy. Only _after_ I have disconnected the power supply and then plugged back in does it every go into this strange mode of rejecting power from the side jack. So typically I check and make sure the LED in front goes on. If so all is fine. If not then I hibernate the machine and come back up right away (takes maybe 3 minutes) and all is fine again. However, it has happend two times in the past that I was in a hurry and plugged in the AC supply on the side jack and did not check the LED. When I came back the machine had run out of battery.

I still think the root of our problem is the same and I could see either the BIOS or the power chip being the cause here. Just that what you are seeing is much worse than what we experience.

Right, and it seems that once the power circuit thinks that something's bad about the power coming in it disables the jack. From there it takes a complete shut down to reset the circuit.

Thanks for the machine details. So upgrading to F.55 does not seem to fix this for you. Luckily hibernation is working for me, so it's not to bad dealing with this (as long as I catch it).

I am chatting with an HP technician about this right now in the other window. She claims HP does not know of this issue but suggests a BIOS upgrade (of course). I am running Linux and they only support upgrading from Windows. Do you run Windows or Linux? What BIOS version do you use? Thanks,

Hey, I have the exact same issue that kf_man is describing with my X1230US except that I am not using a replicator. It just happens when I unplug the power supply on the side of the laptop and operate it without power supply for a while. Then when I come back and plug the supply back into the side jack the laptop LED does _not_ indicate that the battery is being charged. In fact the battery will run dry after a while. On the software side, however, the indicator in the system tray does change to indicate that the power supply was plugged back in.

The LED I am talking about is the one with the little flash symbol. During normal operation (i.e. when not in the faulty mode) this LED will only be on when the battery is installed. I can take the battery out and the LED will turn off, indicating that no battery is present and not being charged. So I figured that the problem may be with a battery that is going bad. To test this theory I went ahead and removed the battery from the laptop while it was in the faulty mode described above, expecting that the laptop should keep running fine, power being supplied by the external power supply. BUT instead the laptop turned off as if I had cut it off any power supply!!! So there goes this theory...

Has anybody received an official statement from HP about what could be the cause of this issue. It is really the only complaint I have with the X1000 but it sure is very annoying, especailly since it seems to happen more and more frequently.

Thanks,
