Hello Everyone! About 1 month ago, my laptop began random shutdowns when on battery power only. The battery could be at 30% or 99%. Shutdowns were so few I thought perhaps the battery clip on the bottom was getting pulled back and the battery temporarily removed, causing the shutdown. Nope! The event log gives no information to anything prior to shutdown, unless there is something 40 mins or hours before showing as a warning that I do not reconize? I think it happened most times when coming out of hibernation...but NOT always! Now twice it has happened that the laptop is closed, and when opened back up it is shut down. I'm not sure if it was plugged in first then cover shut, or of the cover was shut then it was plugged in (it wasn't me, and my husband is at work). I would guess the second, because that would make sense if it shut down after the cover was shut, then plugged in (as the problem is notably when NOT plugged). I used to be a network admin, so I know a bit about computers, but I just can't figure it out? Does anyone have a clue based on that description? I did my laptop diagnostics last weekend, and everything appeared fine. I installed an extra 1Gb ram a few months ago (adding to my 512mb), but that was long before this prob (and the ram was bought directly from dell). everything else seems fine on here. I dont ever travel anywhere with it, we just move it about the condo? Here is the HTJ log just incase... Please help! I am a student and teaching assistant and I am afraid I will be working on my thesis and have it shutdown on me! And I'm even more afraid I will have to call Dell and have a nice phone chat with them for 6 hours before they decide they need to ship away my computer!
