I have a problem with my secondary battery. Just ago, I closed my notebook (a HP Probook 6450b) and when i opened it again, it didn't wake up from standby mode because my first battery was running low. However, i had/have a fully charged secondary battery connected to the notebook. Why didn't Ubuntu recognize that the secondary battery had plenty of charge (under Windows 7 this wasn't a problem)? (Also, before closing the notebook, Ubuntu showed me a remaining charge of 2% for about 20 minutes)
As a second question, is there a way that i can make Ubuntu decharge my secondary battery first (is usually decharges the "internal" battery first, but i want the other one to get decharged first)?
