I have a Dell XPS M1210 that just turned two years old.
After one year, my 6-cell battery started to falter, so I purchased a new 9-cell Dell battery. This worked fine until a couple of months ago when I noticed that my 65W adaptor was frayed. I bought a new 65W Dell adaptor and it worked well for about a week until I noticed that my battery wasn’t charging at times. If I was patient, or unplugged the adaptor and plugged it back in, the battery began charging and all was saved.
This lasted only a short time until my battery wouldn’t charge at all for long periods of time, and sometimes the computer wouldn’t turn on, even if plugged into the wall. I thought it might still be the adaptor, so I borrowed a fully functioning 90W Dell adaptor from a family member to test the system. This worked better, but still not great. When I removed the battery and started only from AC power, the functionality was also intermittent. Usually, if the computer actually started, I received the start-up error “The AC Adaptor Type could not be determined, etc. etc. etc.” After pressing F1, the computer booted, but if the battery wasn’t in, the computer didn’t usually last long before shutting off. Unsure if maybe the battery was the problem, I put the 6-cell battery back in, and it too wouldn’t charge, although (together with the 90W adaptor) my computer would at least start more consistently if plugged in. The error remained however, and sometimes the system stops recognizing power and switches to my ever dwindling battery power until the adaptor is recognized again.
I called Dell. No help. I checked Dell forums. No help.
I perused Google and it was far more helpful than Dell, yet yielded no results (beyond the usual, buy a new adaptor, buy a new battery [check, check]) except to flash the BIOS. So, I updated my BIOS from its A05 version to the A08, and anxiously awaited the reboot... when I received the adaptor error once again. I have run all fathomable diagnostics and everything comes back squeaky clean (except the battery/adaptor test, naturally).
Clearly, the battery isn’t the issue, the adaptor isn’t the issue, the BIOS is fine, and there isn’t any visible damage to the power jack on the system itself. Everything is intact and fully functioning. Just not as a single unit. The only other thing I can think of is the motherboard ... but the diagnostics come back clean, so ... I’m confused.
In sum:
Dell XPS M120
OS: Windows XP Media Center (latest SP ... 3, I think)
6-cell & 9-cell battery
65W adaptor (x 2) & 90W adaptor
BIOS A08
Any input, thoughts, ideas, additional confusion? I’ll take what I can get.
Thanks!!
