I have an Acer Travelmate 2200 (from october-ish 2005) which, I have to admit was/is a pretty good laptop, however, this laptop has come across a problem. When I turned it on after being off through the night I noticed a "critical battery" pop up balloon in the bottom right of the screen, though I found this strange, as the laptop was plugged into the mains. I tried another power adapter I have for this particular laptop, as me and my brother bought the same laptop at the same time... I found the same problem "critical battery". I also had the "critical battery" problem when I used my brothers battery, whilst plugged into the mains with either adapter.
What I tried next was taking OUT the battery and leaving the laptop plugged into the mains, then running it. After cutting out a few times (on both power adapters) it booted into windows, it was fine for a few minutes, I thought I had overcome the problem, and that I needed a new battery. This was when I had the "critical battery" balloon again, WITH NO BATTERY IN, only plugged in the mains, by this point I was extremely puzzled. The laptop is repeatedly cutting out, I would send it back, but I have no warranty remaining, if there is nothing simple I can do I will send it back to Acer to get it fixed.
Thankyou in advance for any help. Please redirect me if I put this question in the wrong forum, it was a guess between Windows and Hardware (I will not double post).
