->   I found out later that she was running the laptop on line
->  voltage nearly all the time.I told her that a rechargable
->  battery should be discharged or it would SET at a high
->  voltage point.I told her to run WITHOUT the battery.
->  Since her rechargable loses about 1 % voltage per day,
->  I suggest she leave the battery out and recharge it about
->  once a month or before she needs to go off house voltage. 

 Be very carefull of running a Laptop withouth the Battery using hte
External Power Adapter. Some require the Battery to Stabilize the
Extreemly Cheap AC adapters adapters used.
 And NaMH and Li-ion Batteries DO NOT need discharge cycles like the
NiCads did so they will not go bad. 
The point about the Self discharge is a good one though. I usualy Top
Off batteries every 4 months or so on Seldom used equipment.
