UX31 power management

[andycai]

I installed fresh Windows 7 professional and Power Wiz, Power4Gear Hybrid and PWR option. I'm not able to set power management. It's always fully charged. I was told this will shorten my battery life? On Lenovo Thinkpad, I had option to specify when to charge and to what level. Any thoughts? Thanks.

There is no programmable charge limit on any ASUS I have seen. It is hard limited at 95% to prevent overcharging.

How can it be hard limited at 95% if the battery meter always reads 100%?

From the manual of the UX31E, English edition, P.30:

The battery starts charging when the charge remaining in
the battery drops below 95%. This prevents the battery from
charging frequently. Minimizing the recharge cycles helps
prolong battery life.

From the manual of the UX31E, English edition, P.30:

Just wondering is it bad to charge the battery til it reaches 100%? Or should we unplug it when it reach 95% (in my case 97% when it turns green) Ive been waiting for it to reach 100 before unpluggin it from the charger

From the manual of the UX31E, English edition, P.30:

Well then my ux21 isn't functioning properly. I've never seen the battery drop below 100% when plugged in. It does drop a few percent per day if unplugged though.

This is a standard feature of Asus notebooks, but maybe the UX series is different and the user manual is wrong. Before you assume there is a problem see what other owners say.

When battery level reaches 100%, does the charger keep charging? Or is it smart enough to stop right there?

I cannot say for the UX31 in particular, but all other Asus notebook are smart enough to stop. If i leave my N50 plugged in for a day, it will read something like 98% Not Charging on the Windows 7 battery indicator.

The 95% is to prevent battery deterioration arising from such a scenario:

Unplug laptop to move it from room to kitchen... 100% to 99%... plug it back in, 99% back to 100%.
