Windows 7: Keyboard doesn't work after waking up my machine.

Ok, To be quite honest I never really use the sleep feature on my computer, possibly the only time I ever did was to test it was working, But anyway the problem is that whenever I'd have My machine asleep whether it be pressing the button by accident or doing it intentionally, when I tell it to wake it up, It does everything normally (Brings back Desktop etc.) but the keyboard (And sometimes the mouse) are practically dead, No lights on and stuff, and doesn't come back unless I restart and on some occasions completely unplug the power cables for about half an hour.

I did some research around and I couldn't find anything helpful, Some suggested upgrading the Bios (Done) and some said turning off the respective settings in "Power options" and the "Device manager" (Did that too) and still no result, I'm using windows 7 SP1 and all the latest drivers and updates, My motherboard is an Intel DH67CLB3 with latest bios.



The real problem for me is that I don't know how long it has been going on for and whether or not I had anything to do with it, because like I said I rarely use the sleep button, But whenever I do It always does this on wakeup.

Can Anyone help?

Method 1
Verify if the keyboard is enabled to wake the computer out of sleep mode.

a) Open the Keyboard control panel item, as described in Method 1.
b) Click the Hardware tab, and then click Properties.
c) Click the Change Settings button

Note This step requires Administrator access
d) Click the Power Management tab, and then verify that Allow this device to wake the computer is enabled.
e) Click OK, and then click OK again.


Method 2
If the above step fails then make sure that you have updated the drivers for the keyboard from the manufacturer website.
Update a driver for hardware that isn't working properly

Hope that helps, got it from microsoft answers

Thanks for the suggestions but unfortunately I came to find that I already have the Allow this device to wake the computer feature enabled, And I didn't have much luck with Method 2 either.


Thanks for your help anyway, Any other suggestions?
