I have a Sony Vaio PCG-F690 that I really need to get inside I have looked everywhere for any kind of info, but have found nothing. I know that I have a bad solder on mypower adaptor I can feel the very "loose" wiggle" feeling in it. I went to Electronic Parts Outlet and had my cord tested it was not my cord the technician as well said that the adaptor connection was my problem (90%) sure he said. If it's not to much trouble could someone help me find some info on how to open this laptop and get to the problem area. any help would be greatly appreciated. Thanks in Advance. Sony Vaio PCG-F690.
