Acer 5742g instead of waking from sleep, shuts down when on battery

[fc bayern]

I have a solid hackintosh laptop , Acer 5742g , almost 95% functional, one big problem that boders me is when i put the laptop to sleep.

When on AC power no issues at all, the laptop sleeps and wakes up without problems.

But when on battery, when I put the lappy to sleep and leave it to sleep, lets say for 1 or 2 hours, then when waking from sleep, instead of waking up - it shuts down. When I try to wake up after 5 -10 min after sleep - no problem.

I think that the problem is that Mac OSX doesnt manage or see the battery power correctrly.

I have installed voodobattery 1.3.3 - no KP everyting woks OK, i have the battery icon and the battery power, that part is ok. Also I have calibrated my battery, according to a litle app caleed Watts.

This is so important to me because it is a laptop, it is handy to sleep the lappy and the wake up - instead of turning the system on and off everytime, cuz I'm a heavy user of the sleep.

Here the info from system profiler:
