Yeah, I know my battery is probably hosed, but every time I reach 5%, my MacBook shuts down, as it expects the battery to be able to run down to 1% before hibernating.
However I would like it to hibernate and not shutdown, when I run out of power, so is it possible to make my MacBook hibernate at like 5-10%?
My MacBook is over 2 years old and I'm not going to buy a new battery. The battery only lasts 1-2 hours.
I have tried calibrating the battery, resetting the SMC etc., without any noticeable effect.
