Did my battery die or is my TX770p defective?

So about a day ago, while contemplating whether or not to purchase an extended battery, I tried remove the battery while the computer was on (to check what mA my battery was). Once I finally got it off and put it back on, I decided to use BattStat to check the wear level. To my surprise, the battery did not show up (not recognized nor charging).

I thought this was a fluke, so I just removed the battery again, and reseated again.... nothing. So as the ultimate test, I just unplugged the AC. Dead.

When plugged back in, the battery indicator does not blink or show any charging when the computer is off and in windows... does not even detect the battery.

The last time I unplugged the AC adapter was probably a couple weeks ago and when I checked the wear level then, it was only @ 1%.

I've tried the "battery in the freezer" trick with no results along with holding the power button to reset the capacitor trick, also with no results.
Is it possible that there is something faulty within my computer - or is it likely that it is just the battery?

I am really hoping it is the latter (as I decided to buy the extended battery in light of this), but found it surprising, as the laptop was working fine two weeks ago and in tip top shape.

Any help would be appreciated. Thanks.

 

I think it might be your battery.
On my SZ after 2 weeks of use - sent it to sleep, unpluggeed AC, went to another place, plugged in computer started, wondered why it fully booted, then found the battery was shown as havin 100% charge but didn't give off any charge.
A little while later my SZ decided to claim it wasn't a Sony battery...
Discharge Mainboard didn't do anything - and Sony's suggestion of a System Restore (microsoft) mesed up a few settings (in the end I used my recovery discs).
But I got a new battery under warranty, and ever since its been running fine.
Your battery probably died.

One difference in my case the battery indicator was falshing rapidly, Sony support didn't know what it meant.

Ah well, doesn't matter, they were nice and friendly and solved my problem.

My suggestion - get your battery changed.

 

thanks for the reply.. turns out it was just the battery

I went out on a limb and bought a new extended battery and it is cruising along happily now.

 

Did you get a replacement battery under warranty, or was it out of warranty already??

 

I didn't even bother to check the warranty on the battery. I just assumed it was out since I've had the laptop/battery for over a year.

Sad to see it go. Lesson learned - don't leave battery in while leaving computer on for a week at a time.
