blow up lately. Even a seemingly minor fizzle turned out to be a false alarm. While it's not laptop batteries this time, it seems that Sony has run into a bit of trouble with some of the AC adapters used for its VAIO all-in-one desktops and docking stations. Specifically, the insulation used in adapters for the company's VGC-LT and VGC-JS2 series desktops and VGP-PRBX1 and VGP-PRFE1 docking stations can apparently fail over time and pose an electrical shock hazard for users, although there have been no reports of injuries to date (and only four reports of any short circuiting). Still, it's probably a good idea to take Sony up on its offer for a free replacement. Hit up the link below for all the necessary details.
