> Do you mean a fully charged battery only lasts 4 ~ 6 hours?

I will do some other tests next days but if a suspend my laptop at 1:00 with a battery loaded about 40%, when I try to resume at 7:00, the laptop refuse to resume (battery empty). I have to plug in the charger in order to resume (normal boot because a halt was certainly requested by the system on battery low).

With :
$ sudo sh -c 'echo mem > /sys/power/state'
$ sudo sh -c 'echo deep > /sys/power/mem_sleep'
the problem disappears.
