I put together a system for my dad at christmas and there's an issue I don't understand.
It's running Windows 8 (clean install) on on an Intel DH61DL motherboard, latest bios (2/26/2013 - 0113), i5-2400, crucial dimms, atheros ar9280 wifi card, crucial m4 ssd, liteon bluray.
When the system goes to sleep after the automatic sleep timeout it will not wake up. The only way to get the system to come back is to pull the power cable, wait 20 minutes and power up again.
My guess (likely nonsense) as to what is happening here is that there is something stopping the system coming out of sleep and there is a capacitor on the board that is keeping the system state for 20 minutes.
I've disabled the automatic sleep mode in windows and everything works fine (has done since Christmas). I can live with this as it's a desktop system and so sleep isn't really mandatory (though it would be good if it worked as it should!). The thing that bugs me though is that if Window 8 enters sleep though Setting->Power->Sleep then the system wakes up just fine.
Anyone got any ideas what is going on here?
Thanks,
Dave
