Makes me wonder if the vaio pocket has this kind of hidden menu somewhere???
Disclaimer. I take no responsibility for any consequences caused by this. Using service menu is inherently dangerous, difficulties during the process could cause the device to stop functioning and irreparably damage the product. If you do damage the product in this way, your supplier will charge for repair. (As said in the avforums thread)
