Sony Hibernation Crashes
If you have a Sony Vaio that repeatedly blue screens going into hibernation or standby and you are at your wit’s end try disabling the HDAUDIO SoftV92 Data Fax Modem with SmartCP device. After applying all of the special-request patches from Microsoft and all of the latest drivers from Sony, this was the only step that resolved the issue for me on a VGN-SZ491N.
This was the last straw with Sony for me. First it was their horrible tech support, then their dismantling of the direct EDU sales division. Add in all the evidence of horrible driver and hardware interaction, experienced in this instance and a multitude of others over the course of 2 years, and I can’t in good conscience advocate a purchase of their product.
