If Your Sage Box Starts Forgetting To Wake Up From S3 Hibernation

[hmca]

For a year my Sage box woke from S3 to record then went back to sleep. Then I started having problems with it not waking for recording events and I could not figure out why. Eventually I traced the problem to an unstable 5V rail in the PSU when I could not even start the computer manually. Sent the Zalman back under warrenty and in the mean time purchased a Fortron 400W Silent PS. This unit restored the Toaster like reliability I had enjoyed before.
However it only lasted about 2 months. Slowly a recording event was missed, then two, then a complete weekend. I figured it had to be the software, what with all the upgrades and tinkering I had done. I reinstalled Sage. Didn't help. Reinstalled Sage with out saving the properties file. Still nothing. I next exercised the nuclear option and Level one formated the windows partition. This cured the problem, or so I thought. Less than two weeks later the problem was back, with theSage box missing events.
By this time the warrenty Zalman 300W was back so I swapped out the Fortron. Immediately my toaster was back. Everything was back to normal. Apparently the 5V rail is not stable 100% of the time on this Fortron. While the Fortron may be good enough for a standard computer where you manually start it up, it is not good enough to power up from S3 hibernation.
So if anybody else has a Sage Box that sometimes forgets to wake for a recording event, consider the power supply (PSU). It worked for me.
