Sleep cmd not recognized on new motherboard

bobland · 13 May 2014

I built a new computer for my wife. The motherboard is an Asrock FM2A75M Pro4+, with an AMD A6-5400k CPU. Everything works fine, except for one thing. The CPU is an A series which means it has built in graphics similar to a 7870 or the like. This means that I didn't have to buy another graphics card thus bringing down the overall price.

The gotcha in this case is there is no "Sleep" option. Windows "requires" a graphics card for use of the sleep option. I use the sleep option to put the computer to sleep when she forgets (which is most of the time) and wake it past midnight to backup her work files (Macrium) then put it back to sleep.

On the old system I used this with success:
Rundll32.exe Powrprof.dll,SetSuspendState Sleep

For hibernation, I found variants on this such as Rundll32.exe Powrprof.dll,SetSuspendState 0,1,0 which works at the command line but not via Task Scheduler.

If anyone has an idea how to get this working, I'd appreciate reading about it.

Thanks,
Burt

Well; the biggest problem with this is; if your motherboard does not have the option/support for "sleep" mode via the motherboard bios in power management; then there is a chance you might not be able to get it to sleep at all. Now; Ive never heard of any motherboard not having a sleep mode option(via windows even) so you might have to do without it. Best thing i can think of is to check the motherboard manufacturers site for any bios updates that might add sleep to it. Either that or contact the motherboard manufacturer and see what they have to say about it.
