Dell has identified several products (4 million in all) that may contain batteries manufactured by Sony that are defective. The affected products are as follows: Latitude: D410, D500, D505, D510, D520, D600, D610, D620, D800, D810 Inspiron: 500M, 510M, 600M, 700M, 710M, 6000, 6400, 8500, 8600, 9100, 9200, 9300, 9400, E1505, E1705 Precision: M20, M60, M70, M90 XPS: XPS, XPS Gen2, XPS M170, XPS M1710 If you own one of these products, Dell has set up a specific website where you can check your battery serial number and learn what to do next. Is this just one more problem for Sony? They had the rootkit problem; the delay to the PS3 ; Blu Ray vs. HD , with a delay and the first models not being able to play movies -- what's next? Oh yeah -- they are struggling in their launch of a music service for their PSP due to DRM issues .
