Recently I switched from buying off the shelf machines to building at work (Building AMD FX-6100 or FX-8100, older ones are A8 series or Phenom II, with Windows 7 Pro). Without going in to the details of that, everything has been great, except that some of the machines are having an issue where they will not 'wake up' from sleep mode.
The machines run fine all day as long as they are not set to sleep (or are in use). They are also 100% if shut down (not put to sleep).
However, if the user puts the machine to sleep, or it goes to sleep, many times they are unable to wake it up. Pressing keys, moving mouse, etc. no help. In fact, worse is that the machine will no longer boot! It goes through the bios screen, then you have no video (black screen) when Windows starts to load.
Even if you hard power off the machine, that usually does not fix it! I found if you press the reset button while windows starts to load, that sometimes does the trick. It's as if Windows is in some kind of strange state.
Just wondering if anyone else has seen this or has any ideas?
The motherboards are all Gigabyte, GA-A75M-S2V - and I think it may be related to this board, since I have some newer Gigabyte boards that so far do not have this issue. I have updated the bios on all of them, so that should be ok.
