Worth a try to solve your Asus Battery Problem

Well... I tried and didnt solve my problem but it seems some people might find it useful... I put some info and the link and hope will work with you...

Is Your Notebook Battery Losing Life Fast? It Might Not Be a Battery Problem, ubmitted by MysticGolem


Battery Problems with Asus Laptops
Recently there have been a lot of complaints by Asus notebook owners finding that the battery life of their newly purchased notebooks was deteriorating rapidly. Battery life would drop 35% after just a couple of months of usage. I decided to provide as much real proof as possible in this review showing that the problem is not the battery per se, but rather a firmware coding issue with the notebook that causes it to grossly under estimate actual battery life left and shut down prematurely. In other words, the notebook thinks there is 0 - 5% battery life left when in actual fact there might be up to 30% -- or an hour's worth of life. This may also be a problem for other notebook users outside of the Asus brand and is therefore worth anyone reading to understand what causes a notebook to shut down when it thinks battery life has become critical.....

During the conversation in the very active thread discussing this topic, people suggested these as possible solutions for "fixing" the battery:
Restart the computer multiple times
Ignore third party programs and just use Windows Battery Miser (battery level indicator program within Windows)
Delete all third party programs
Complete a Battery Calibration
Do a guided Battery Calibration written by jsis.
Use the recovery discs to get back to Asus default condition on the laptop
Format the laptop and start from scratch
Remove battery from laptop and restart, then place it back in
Continuously replace your battery when wear percentages appear abnormal..........

Conclusion
Hence, the battery wear and battery life problem can be attributed to the ACPI being badly coded, thus yielding a lower amount of battery life than anticipated. The ACPI is the source information for Windows Battery Miser, all third party programs, and is also correlated to the BIOS when conducting the calibration tool, which did not solve this problem either. The only workaround right now is it to uncheck the critical alarm, turning it off, so that you get the entire length of your battery life, but there are implications for doing so (such as not actually knowing when your battery will give out and losing work). The ACPI is the problem; companies need to test their products and coding to ensure problems like this do not happen!
