T400: Battery indicator light blinking orange light

[msandeep9]

I am using T400 laptop, recently a month back I had a problem with battery charging, which when contacted lenovo support they asked me to perform the battery re-set, which I did and now my battery is charing well, but now the problem is battery indicator light beside the wireless, caps-lock indicator is blinking orange even thought my battery is well charged and when cursor is placed on the power manager it is showing battery remaining status which is fine, but along with that it is also showing Battery 2: Error detected. And when opened power manager, even there I am seeing Main battery condition as good and second battery condition as error.

Can anyone please let me know why would this error come and how to resolve it? By any chance would T400 will have 2 batteries?

Please let me know if you need any thing else.

update to version 3.31 should help http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-70601

Yes, it can have two, UltraBay battery is "Battery 2", and it's installed in place of optical drive. Try resetting your UltraBay battery through Power Manager.
