And here I thought I could score a free laptop battery (brand new!).
HP is recalling laptop batteries from a couple of brands because it just might go KABLOOEY on you (via Chris Null). So if you have a HP Compaq, HP Pavilion, Compaq Presario or HP, you need to validate your battery. If it's one of the models they are recalling, congratulations, you get a new battery for free!
In the meantime, suit up.
