With my first battery, I could run it down to where the machine forced sleep, then wake up in the morning, plug it in, and resume. This even on my lazy sleep days that approach 10-12 hours.
With the new battery I bought recently, it's not making it through the night. Not sure when it powers off, but it's always dead when I wake back up. Anyone know where this is controlled, and a way to possibly have the machine go into sleep a tad bit earlier?
