Battery won't charge past 9%?

Just when I thought my G73 woes were over with it seems my battery has decided to pull a fast one on me and refuses to charge beyond 9%. I plug the AC adapter in, Windows Power Management does its thing and says charging and about 30 seconds later the build-up animation stops and it just says 9% (plugged-in, charging) but it's quite obvious the battery is not holding the charge as it never moves past 9%.

Does Asus happen to have a battery calibration utility by chance like Apple does? Wouldn't mind performing some checks on it to see just what the heck is going on now.

 

I am assuming you have not had the Batt for a long time. It sounds (without knowing any details) as the batt is faulty. As you say Apple do a Batt diag and there are other (for Mac's) you can download of off the net.

I had to replace mine recently in my MAC after 150 cycles, which was about 2 years. Same issue, would not charge past 10%.

 

Are you sure it's not 90%- only 9? I know that in order to lengthen battery life it won't push it past like 95% unless it's already below that.

Sounds like you have a bad battery though.

 

you might also want to check your power brick. It may be the case that it is charging, but maybe the power brick is faulty and charges slower rather than the regular rate it should be charging at.

 

Try resetting the battery calibration, no programs, just a nearly complete discharge (run the laptop on battery until it shuts down). You can either do it in windows while browsing/killing time or via the BIOS. Also make sure no plastic or dust is stuck in the battery connectors or battery itself. If those fail you have an RMA :/

 

Download HWMonitor from here:

CPUID HWMonitor

and see what your battery wear level is. This will give you an additional info about battery health or will confirm that it's faulty.
