My lenovo x61 is 15 months old and the 8 cell battery on it was giving me around 4hrs battery life.. and then couple of weeks ago the system update software updated the bios and whole other bunch of software and after that the battery light started to blink when AC charger was plugged in and it would not charge the battery. The battery information says only around 320 cycles. and that battery cannot be charged.
I dont think a bettery can just die.. some firmware on the battery chip is causing this. lenovo refused to exchange it as it was just out of warranty. Is there a solution to get that battery fixed by some kind of firware reset? All this problem started after the bios and other updates done by the system update software.
Any advise to get the battery working would be appreciated.
Lenovo X61 type 7764-cto

Same problem, same computer here. I bought mine in September of 2007... so about the same age. Today... I came home to a blinking battery light and some warning from Lenovo's Message Center saying that I need to replace my battery.
Is this some hoax? How can it be working perfectly from day one and then just stop working all of a sudden?

i have the very same problem with a X61s bought around april last year.
Battery neither charges nor discharges.
Some details the windows battery application (Energy Manager?) says:
Remaining capacity: 84%
# of Cycles: 51
Production date: March, 12th 2008
FRU-Part #: 42T5266
The problem seems to be the very same as in the following URL:
Unfortunately the tool says that my battery is not eligible for replacement.
This is pretty odd as i am usually used to the fact that batteries keep loosing capacity over time but do not completely refuse to work as in this case.

I met the same problem.
I bought my X61 on Sept. 2007.
6 weeks ago, when I was using the laptop, suddenly I noticed the battery indicator light was blinking very quickly. It's abnormal. Then I found the battery neither charged nor discharged. Now I have to use my AC adaptor always.
My battery's FRU P/N is 42T4505, I checked the recent recall:
But my FRU number is not listed on that page.
I downloaded the "Battery Verification Tool" from this page and run, then the tool direct to a webpage which said I couldn't replace the battery from Lenovo. And I found they will only change battery for free for those user who satisfied their 3 terms simultaneously
I checked by the windows battery manager, there isn't any warning message like "Irreparable damage" or "Battery cannot be charged" described on the above recall page. It only said the battery status is poor.
Does anyone know any other solution on this issue?
