I have not noticed timing changes BUT...

I have read about and confirmed S3 sleep bug where if you go to S3 sleep, resume, then re-enter S3 sleep, unit will not wake up. After hard power down, and unplug, attempts to re-start fail with Blue LED, Force RESET, CMOS clear, PWR/RST flashing. (BIOS G25\P06)

Unfortunately system went to sleep today twice as I hadn't changed appropriate settings until after this mess occurred.

Any idea what this error mode is? I performed CMOS clear with jumper, but still no boot until one of the times I switched PS off and the Force RESET light went steady so I powered on PS immediately (before Caps discharged) and powered on unit OK. Subsequent power off of PS resulted in same state, now only restarts after shutdown if PS switch left on. (so far)

Bad PS or on board power? Does my CMOS Battery need recharge time?

Any helpful comments appreciated.
