Inspiron 1100 AC adaptor connected, not recognized
Hi, I recently updated BIOS of my Inspiron 1100 from A06 to A32 and I start to have all sorts of power management problems.
First, coming back from "standby" mode to normal operation. HDD runs, and fans runs, but no display. Someone suggested I should disable USB hub power management, which I did today, and hoping it fixed.
The second problem is the topic of this thread. When I work with AC adaptor connected, it shows the icon indicating it's main-powered. If I unplug the adaptor, the icon changes to the battery icon. Normal so far.
Here, when I re-plug the adaptor, it still shows the battery icon, no AC power icon. How many times I tried, same. When I reboot, it show AC power icon though. So it's not the problem of intermittent connector etc.
It's very annoying and I wish I could go back to the earlier BIOS.. Anyone with similar problem? Cheers,

- Well, I believe, it's not working as I observed yesterday. Booted from the battery and later plugged in the adaptor, for the last 5 minutes XP doesn't recognise the adaptor and keeps discharging the battery.
It appears that the old versions of bios release note seem to contain the same issues and claim this symptom has been resolved. It is sadly never true in my case.
To examine any difference an earlier bios makes, I managed to downgrade to A31 from A32. This happened to be a simple task with the help of bay-wolf CD image. Sadly the same problem still persists.

I figured perhaps the bios only occasionally checks whether ac source exists. So I rebooted from xp and checked how long it presistently shows the battery icon and keeps discharging the battery after re-plugging the adaptor in. About 1 minute, it eventually found the adaptor. It is not an instant reaction that I enjoyed with previous bios (ver. A06) but at least it works. The case resolved.
