Unless you regularly don a Nomex jumpsuit while using your HP notebook, you should probably look into the company's latest recall update. Around this time last year, the computer maker recalled 70,000 laptop batteries after a few reported incidents of units overheating, rupturing, and ultimately catching fire.
The company has now added 54,000 batteries to that list, which were sold with notebooks nationwide from August 2007 through July 2008 for between $500 and $3,000. The expansion was prompted after HP received 38 additional reports of the batteries overheating, causing 11 minor injuries.
The following models were included in the recall dating back to May 14, 2009: HP Pavilion dv2000, dv2500, dv2700, dv6000, dv6500, dv6700, dx6000, dx6500, dx6700, dv9000, dv9500, dv9700, Compaq Presario, A900, C700, F500, F700, V3000, V3500, V3700, V6000, V6500, V6700, HP G6000, and G7000. The following models were added this May 19: HP Compaq 6510b, 6515b, 6710b, 6710s, 6715b, 6715s and 6720s.
