Laptop Battery problem
I am running XFCE 4.8 on debian wheezy on my laptop and since about two
weeks the xfce Power Manager gets the battery charge percentage wrong,
the most critical problem being that the machine shuts off without any
I wonder where the problem might be.
Indeed this battery is getting old (3 years now) and less efficient,
but I can't explain why suddenly Xfce Power Manager is getting it so
wrong given that it was working like a charm (even giving a pretty
accurate esteem of remaining time). I imagine Power Manager is relying
on some lower level (software, kernel?)features, maybe in the kernel?
Of course I imagine this could also be a hardware problem, as I guess
there must be some electronics communicating the battery charge?
I am a little confused by the many, somewhat mixed and not-so-clear
sources on the net addressing 'battery calibration' in various ways. Let
alone 'battery revitalising' by putting it in the fridge etc. The
current focus would be about getting an - at least reliable - estimate,
and what's more warning, about battery power left avoiding the machine
to abruptly shut off.
Any suggestion etc. appreciated.
