Z580 with windows 8: very poor battery life

Hi,

 

I have a Z580 ideapad (i3), since I upgraded my computer with windows 8 pro, the battery life is about 2 hours only:  Power saver mode + brightness 50% + Nvidia card is off (instead of + than 4h  with Win 7). And since that time, the fan is always on and the fan control button is not working.


All the driver are up to date, i have the last "lenovo battery manager" installed. Do you know if a fix or a bios update is available for this computer? 

 

Thanks in advance!

Hi sika95
Actually the lenovo battery manager of windows 8 is bugged and doesn't allow some features to work. This is being discussed here

The temporary fix is to use the windows 7 lenovo power manager. You can download it from the driver page.
