Information: Update BIOS and Battery Firmware to ensure full charge capacity

2010-08-18, 15:19 PM

Is your system’s BIOS and battery firmware updated to the latest level?

 

If not, you may not be getting the maximum capacity and run time from your battery!

Lenovo’s engineering team released updated BIOS and battery firmware in July that is applicable to customers who have ThinkPad models:

X100e, L410/L510, L412/L512, SL410/SL510, T410/T410i, T510,T510i, W510 or ThinkPad Edge, 13, 14, or 15 inch units. 

 

Customers who use Lenovo ThinkVantage Toolbox would have received a notification and opportunity to apply this update, and Lenovo’s ThinkVantage System Update tool would also identify and apply these updates

If you aren’t using either of these tools, and have one of the systems above, please follow this link to our support site.  You can learn more there, and download and install the updates specific to your system.

Probably also worth mentioning, is an earlier tip applicable to X200t and X201t tablet users who have 8 cell extended batteries.  This technical tip and related BIOS updates ensure these batteries properly charge to their full capacities, and resolves a particular symptom where the battery would stop charging at less than 50%.

Recommendation before updating bios:

 

- detach all devices from you system

- undock your system, if docked

- start from a cold boot. (shutting down the system completely, wait 15 min, start up again)

- if possible, upgrade with a cd-rom drive

 

Edit: Recommendation added.
