I've just replaced the failed Toshiba hard drive in a Vaio VGN-S4XP/B with a Seagate ST9160821AS 160GB SATA drive, which I felt quite competent in achieving, observing ESD precautions. When I reassembled the laptop and attempted to boot - nothing. No POST, no lights, no activity at all. Not even a charging light for the battery. I have checked the obvious i.e. the power adapter and my multimeter reads +19.5V on the input socket. Am I missing something here? Need I reset CMOS, and if so where is the darn battery located on this model? I refuse to believe the board is nuked as I have observed every precaution. Any help here would be greatly appreciated.
