recharing and batteries

[mtran@dolphin.upenn.edu (Mark Tran)]

Hi all,

I have a 755Cs and I only take it out once in a while.  Now, my question is,
is it okay for me to leave my battery inside the computer so that it is
always recharging or should I take it out and just power my TP with the 
AC adapter when at home?  Another problem I'm having is my battery seems 
to drain itself out when it is not in use.  Is this normal or is my 
battery defective?  I've tried discharging it in hopes of solving the 
problem once but it didn't work.  Thanks.

Mark
