I'm just wondering if anyone else has had or heard of this problem.
I got my T410 (full specs in my sig) new in July, 2010, so I've had it a while and to this point had no problems with it. As I typically do, I set a power-on password (pop) in the BIOS (no other passwords) shortly after initailly setting it up last year. All was fine until this morning when I powered it on. I use the T410 just about daily and everything was fine yesterday right up to when I powered it off last night.
I entered the password this morning as usual and got an "x" displayed indicating the password was wrong. I entered it again figuring I fat-fingered it the first time. Nope, still wrong.
After a few unsuccessful power cycles and re-tries, I figured it was time to try and clear the password and start over.
I followed the steps in the HMM to unplug the coin backup battery and cleared the pop.The T410 now booted into Windows normally (after setting date/time in the BIOS). Several reboots worked fine, as well. I went back into the BIOS and re-entered the same pop and rebooted. I was prompted for the pop, entered it, got the expected "OK" acknowledgement and Windows booted normally.
I'm back up and running normally now (I'm typing this post on it) but since I've never seen this problem before, I'm curious if anyone else has? Should I just write it off as a glitch, or am I looking at an initial symptom of bigger problems yet to come?
