I have just updated the bios to F10A to use a 1055T and it runs sweetly exept that whem the machine goes to sleep it either reboots ot give a BSOD in Vista Ultimate, The previuos bios version did not do this and sleep mode functioned ok. This is when power managemant is S3. It works ok in S1 but, of course that is not as an efficient power saving state. I want my S3 mode back...can anyone help? Thank you.
