I'm running HP 530 laptop and Ubuntu 10.04. My old battery is died some times ago, so I have got the new one.
I'd like to get possibility to change the limits when the charger starts to charge battery (e.g. <50%) and finished (e.g. >80%). It should sufficiently extend the battery life. See How to Prolong Lithum-based Batteries.
I know that Lenovo users are luckily provided with a solution because of the
tp_smapi kernel module.
Is there a solution that helps?
