I have solved my laptop wakeup problem!! DELL 5737 17R I'll try to explain what's happened. After upgrading to Win8.1, windows update try to update the Inter HD Graphics driver preinstalled into dell systems. This video driver is *CRUCIAL* for suspend/Hibernate/LidClose mode to operate properly. This is the signature of the update Win8.1 suggest to apply:  - Intel Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3 - Intel(R) HD Graphics Family  *** DO NOT APPLY THIS UPDATE *** !!! If you do, this will conflict with AMD graphic adapter and result into nasty problems, including: * Unable to restore from black screen if you close lid then reopen* Unable to properly hibernate* Unable to restore from LCD monitor switchoff for powersave IF you see DELL site support, you can notice that the LATEST Intel HD video available is OLDER than the liveupdate installed (from microsoft). Solution: 1. Remove/Uninstall all the AMD stuffs2. Reboot3. Remove the Intel HD Video driver and reinstall the older driver from DELL site4. Reboot (disconnect lan/network... *IMPORTANT*)5. Disable automatic LiveUpdate6. Reattach LAN/network7. Look for available update package, hide "Graphics Adapter WDDM1.1 xxxx" You want now, after a final reboot, to say NO, NO, THANKS, to LiveUpdate of Intel Video Driver. You have now a dell with working sleep/hibernate mode.When i close lid than reopen it, finally the LCD switch back on.Dont allow liveupdate to install that nasty update again. Of course, the AMD accelerated graphics wont work, because all AMD drivers are now missing.I dont really care for now, i will try to reinstall AMD/Catalyst *ONLY* when a newer release will come up from DELL support site. They are stuck at 2013 drivers, these are pretty old, and i am scared they can cause other problems with Win8.1 too. Please DELL, give us a better experience, not let us to waste all the time trying to fix your buggy drivers! Hope this helps anyone, Paolo Marani, Italy
