Updated from Windows 8 to 10, sleep mode is no longer available

A few days ago I updated my HP Envy laptop from Windows 8 to Windows 10. I used to be able to close the lid and the computer would enter sleep mode, and come out of it when I opened the lid. After updating, it now goes into hibernation mode when I close the lid. In the Sleep and Power Settings, the only options available for me to choose for when I close the laptop lid are "Do Nothing," "Hibernate," and "Shut Down."


Following recommendations for similar issues, I updated the driver for my display adapter. Unfortunately, this hasn't changed anything. I've noticed, however, that in the Device Manager, the symbol next to the Intel(R) HD Graphics Family has a little exclamation point in a yellow triangle. Under the display adapter Device status it reads "Windows has stopped this device because it has reported problems. (Code 43)"

In addition to finding no mention of sleep mode anywhere on my computer, I'm now unable to change the screen brightness by any means.


I read somewhere that I can allow sleep mode by changing something related to the BIOS? This sounds complicated. Has anyone else experienced these symptoms? What do you recommend I do?
Thanks!

Go to the advanced settings where you usually change the setting for when the lid is closed, sleep is maybe greyed out? Above that there is a link about showing options that are not available, click it and the option may be made available to you.

I clicked the link I believe you were referring to. Unfortunately it didn't make sleep available.
