Hello,

I have a dell laptop, the vostro 2521 with 2 graphics (intel and amd) and since 2 months I'm having this sleep and wake up from sleep problems. I really use sleep mode a LOT and this problem makes me loosing so much time.
I've tried many solutions but I do have this problem even today.
When I shut the computer down with the sleep option or when I close the lid, sometimes the pc even refuses to sleep, when it sleeps it won't wake up unless I hard turn off it using the on/off button.
When it refuses to sleep, it turns of the screen, and HDD activity seems to stop, the fan stays turning. But it never actually sleeps.
I've just checked some similar problems and I get to this http://www.tomshardware.com/forum/63288-63-windows-refuses-sleep

This solution is about an HP printer, but I don't have an HP printer, just have an MC reader.

I already uninstall and reinstall the video card driver from Dell website, but still not ok.

Thanks!
