No sleep option  

AllanP said:

On a friends HP Pavilion Model p7-1256c I formatted and did a fresh install of W10 Home. All works fine except there is no sleep option.

This sometimes happens to my HP after Repair Installs and version Upgrades. Usually, it's one of two things - disable Fast Startup ( cmd prompt admin/ powercfg -h off / Enter ). May not work but unless you use Hibernation, can't hurt and saves space.
More likely, in my case, at least- If Sleep still doesn't appear, roll back the display driver which Windows Update may have updated to an incompatible newer one- go to
Device Manager/ Display adapters/ r-click driver/ Update driver/ Browse my computer for driver hardware/ Let me pick from a list of available drivers on my computer / select oldest version listed (or use MS Basic) / Next and finish install/ reboot
Sleep should appear now. Test for a few days to see if all is OK with older driver, as far as Display goes, block Windows update from updating that driver or repeat process, if it occurs again. - Prevent Windows Update from Updating Specific Device Driver
Good Luck

I'll be connecting with Barrie's computer shortly and will try all these suggestions out; just want to say thank you all for your help.

Allan,

The HP utility would only find updated drivers if HP had certified them for Windows 10 & that is not the case for your model [you said HP only supported the computer as far as Win8]. Device manager update checks would not be as limited.

Perhaps, in the HP user forums, some other users of the model have reported success in upgrading to Windows 10 & have provided details of the drivers they used.

I think I mentioned before that sleep worked fine on his W10 upgrade from 8. It just hasn't worked since I installled a fresh W10.

Allan,

That reinforces my belief that it is a driver issue.

I always think of the display driver when it comes to sleep problems but I have also seen comments like those you referred to about the chipset drivers being involved as well. That's why a report in the HP user forums about having upgraded to Windows 10 might be your most useful source of advice.

Best of luck,
Denis

Just waiting on Barrie to connect. I may not have disable hibernation; do you think I should do that first?
Just checked the HP forum and sleep mode is a common problem in W10

Allan,

Well done.

Do I now need to nag about making a system image? Macrium Reflect Free is often recommended in this forum and there is plenty of help available here for it, including -
Backup and Restore with Macrium Reflect - TenForumsTutorials
Macrium Software Macrium Reflect Free
Macrium USB - TenForums
Macrium Reflect KnowledgeBase - user guide [version-independent link]

I have always used Acronis TI and am only now studying Macrium Reflect, having finally been convinced of its benefits by another TenForums user only a couple of days ago.

Denis

Thanks Denis. I use Acronis TI but don't up their anual updates and being mostly a Linux user; I use the iso boot to TI and that works for me. Seeing that all the help gotten here is for my friend's PC I'll have to take my TI USB to his place and make an image for him. I feel that I may be about 40% up the geek ladder where my friend is about a 2. I feel lucky to have gotten in in the DOS days messing with autoexec.bat for more memory etc., and feel for the more recent users where graphical is all they know. I don't think I can get Barrie to try Macrum, but will give it a shot.
