My laptop battery died a few days ago, so i decided to see if i could locate the problem. I charged the batteries (the were QUITE low) with an external Li-ion charger. That didnt didnt help. So i grabbed my trusty Fluke, and started to meassure voltages.. the output ground and positive were reading 0.
So my guess is that one (or more) of the protection circuits have been tripped, and then doesnt want to go back to enable. The laptop can see the battery just fine, and read all its info, but it doesnt want to charge it.
Inside the battery are two different SMD IC's:
- BQ29330 http://focus.ti.com/docs/prod/folders/print/bq29330.html#technicaldocuments
- BQ8030DBT
I cant find any specs on the BQ8030DBT tho.
Anyone got an idea on how to enable the battery again?
Thanks in advance!
