I'm helping a friend install XP on Sony VAIO VGN-T16RLP. Actually windows xp was successfully installed. However, can't find any driver. Infact, I can't even locate the model on sony web site. I was referred to Asia Pacific sony web site when I performed a search. I went to this recommended site and yet the model does not exist. This notebook looks like a netwbook. very frustrating. can't get to internet on it because no driver for wireless. no video and other drivers.
See if the wireless adapter is showing up at all in Device Manager (Control Panel, System, Hardware, Device Manager) there may be a clue to the chipset maker (Broadcom, Intel etc) and if the chip model number is there look for a driver on the chip maker's site. Ditto video (always assuming you can see anything on the screen to start with).
Otherwise throw yourself on the mercy of Sony -- somewhere in the organisation, somewhere in the world, there must be drivers for the damned thing.
