Thank you Laurent, that is good to know and sorry for the late reaction, I have been out of town. Another bad influence appears to be the temperature. When the laptop is attached to the power adaptor and folding 24 hours a day the rear bottom part stays rather hot. Temperature seems to be a negative influence on the life of the battery. IMO there are only two choices; stop folding or remove the battery when the PB is used in desktop mode. Here is the lowdown I found on Lithium based batteries; http://www.batteryuniversity.com/parttwo-34.htm Greetings, Andre. -- G-Books is sponsored by http://lowendmac.com/ and...

Battery Query.
Hello All, I'm using my 17 PB 3/4 of the time as a desktop machine connected to the power adaptor. I read somewhere that it would prolong battery life if you removed the battery when connected to the adaptor. The battery would not be continuously charged. Any advice?
