ThinkPad T520, Win7 Pro 64.
TVSU updates Power Manager to V. 6.38. Immediately on reboot notification area shows 0% power and a message stating that a battery error has occurred. The battery LED is now blinking orange and the battery will not charge. Considering that the battery was fully charged and had only 31 cycles on it (although it dates to October 2011) I can only assume that the software has killed the battery. Again, prior to the update there were no indications that the battery was malfunctioning or even losing capacity.
Uninstalling Power Manaager did not help. Re-installing Power Manager did not help.
Is there a way to reset the battery? Am I locked in to buying a Lenovo battery to avoid task bar notifications of a non-genuine battery? Any other ideas would be greatly appreciated. Here in Mexico these batteries are very, very expensive.

Hey there mixz1,
Have you seen this article on how to perform a battery guage reset? Additionally, it may be wise to remove the battery and AC, then press and hold the power button several times to clear residual capacitance and then re-attach them and restart. I hope this helps.

Can you tell me if the battery gauge grayed out by chance?

No. It's black, displaying 0% in white text. Hovering over the icon produces a popup that says "0 minutes remaining. A battery error has occurred. The battery cannot be charged. Replace the battery."
And I repeat, the battery only had 13 cycles on it and was functioning perfectly at 100% capacity before the upgrade.
