ibook g4 battery

[juan123]

Well.....my ibook's battery holds 16% of its capacity according to coconut battery and other utilities. What annoys the heck out of me is not the fact it only lasts 30 mins when run with the battery , but the fact that the laptop just shuts off and doesnt even sleep when the battery gets below 30% charge. How can I get it to at least sleep when it gets low rather than just shut off completely?

Resetting the PMU should fix the problem
