I'm not sure I'd trust XBattery too much. If the computer is forced into sleep sooner than you'd like, buy a new battery. Batteries tend to have a good usable life of 1-3 years, depending on your use, and how soon you want to replace them. If you buy a *new* battery and it repeatedly dies at 80% or after 30 minutes of use, there might be something wrong with your computer. Much more often, however, the problem is related only to the battery. wp <dtpoperator at wp.pl> writes: > ive bought DVI_666 with old battery (6xxx) > and the 65W power supply and ... > > the xbattery app has shown the battery capacity (raw battery info > window) > about 1.48Ah > but after few recharging this amount dropped down to les than 1Ah > well ok ... ive replaced it with A1012 battery model (used too) with > capacity 3.7Ah > > the bad scenario has repeated few times but with less change; now it > has > little bit more than 3.3Ah (in few days) - ive pressed this magic > button in > top-right corner (under the keyboard) - doesnt stop it > > i think that its the matter of power suply (65W and should be 45W) > or the PMU unit in the PB isn't ok > or may be its not right to start recharging (plugging power supply) in > sleep > mode Kynan Shook kshook at mac.com http://homepage.mac.com/kshook/index.html
