The problem is the Laptop is faling to charge the battery (state the obvious!)1) Either the charging circuit has failed, or the connection to the battery or2) The battery has failedHow old is the laptop? if still under warranty return it to the vendor or better take it and get them to try a replacement battery in it. Or take it somewhere 'friendly' where the same laptop is sold and get them to check it outHas the battery any charge indicators on it if you remove if from the laptop? Do they light up if the battery is totally flat they won'tHas anyone you know with a laptop got the same battery in it, swap the batteries if so and see if it charges.
