IT Queries: Computer problems answered

 Toshiba laptop  using Windows XP home edition.  My system was working fine with battery.  

After running low  I charged it up but the battery icon on toolbar has disappeared and I cannot take out the power cord or computer shuts down.  

When I look on power options in control panel it says the battery isn’t there and says power status is AC  and battery status is unkown.  I did have a new battery put in about 18months ago.

That new battery has failed. You may want to contact the dealer and see what they can do for a replacement but warranties are notoriously tricky with batteries.

Lithium Ion batteries prefer to be partially run down rather than fully discharged. The older Nickle Cadmium had a “memory effect” where it was best for you to fully run them down all the time, but modern batteries don’t like that.

You may also want to make sure you are using brand name batteries and the proper, brand name, recharger. Cheap generic replacements can cause problems.
