Still haven't found a bios manual, but anyway. I found a combination of drivers for graphics that does work and allows sleep function without a glitch. amd-catalyst-15.7-without-dotnet45-win8.1-64bit Intel_Iris_15.36.21.64.4222 Uninstalled amd (complete), reboot, intall iris, reboot, install latest amd. Ati probably fixed the issue that did not allow wake from sleep. I downloaded them using amdautodetect utility and intel driver update utility.  
So, I got a Inspiron 3537 i5. Nice laptop for it's price. Downloaded all the manuals, made my recovery DVDs. All was well in my world. First thing I noticed is that there is no info in the manuals for tweaking the BIOS and since it is my first experience with a UEFI bios I was a bit disappointed. Is there a manual available for it? Next I upgraded ATI Drivers to 13.12. I am an old user who always knew that updates were usually a good thing to do. Got in the same problem as many others with PC screen not waking up from sleep. Thought I would do a recovery from the disk, but after trying various combinations (Ctl+F11, F8, F12 etc) I couldn't find a way to boot in the Recovery console. I did the recovery from my DVD and the laptop works fine. Does anybody know how to add in UEFI bios a boot option to the Recovery partition? I undersstand that I have to create a new boot option using "Add boot option" and the two options available are to boot to the 1st (windows EFI) or 2nd (recovery partition), but the path for the recovery efi file to be loaded is unknown (+ you can't have access to the recovery partition to see the contents of it from windows). Any suggestions?
