    my laptop battery has no charge and will not recharge when plugged in . . . does this mean that i have to buy a new battery? or is there something else that could be causing this problem?

    It is most likely the battery. The charging system could have a problem, but in 99% of cases, it is a bad cell in the battery.

    If you are handy, you may be able to open the battery case and test for the bad cell and replace just that. But it would involve cutting and somehow putting it all back together, and depending on the age of the battery and how well it was treated (cycling full discharges, for example, to "condition" the battery), repeating it all again when the next cell goes bad.

    Its not a "good idea" to mess with the battery by replacing cells yourself if it is Lithium Ion type, as they are very fussy as to cell type and charger specifications.

    They tend to get hot and emit flames otherwise.

    In addition, you'll find that it's close to impossible to buy individual Lithium Ion cells, precisely because of the point that kiwiguy makes. :)
