Apparently Apple isn't the only company in the hot seat over its laptop batteries. HP has just announced a recall on 135,000 batteries in HP and Compaq laptops sold between March 2004 and May 2005. The company has received 16 reports of overheating. Unlike Apple's previous battery problems, however, none of the HP batteries have burst into flames. Yet. Affected batteries have barcode labels starting with GC, IA, L0 or L1.
