Stand-by mode gone from Dell Latitude E5550
Hi all,
I have a Dell Latitude E5550 Windows 8.1 computer. I bought it in 2015, worked perfectly fine. A few months ago, the sleep mode disappeared from all menu's (start, power management, etc.). I looked for a solution on several fora, but I haven't found one yet.
When I type "powercfg -a" in command, here is the result:
"The following sleep states are available on this system:
Hibernate
Fast Startup
The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
The following sleep states are not available on this system:
Standby (S2)
The system firmware does not support this standby state.
The following sleep states are not available on this system:
Standby (S3)
The system firmware does not support this standby state.
The following sleep states are not available on this system:
Standby (Connected)
The system firmware does not support this standby state.
Hybrid Sleep
Standby (S3) is not available."
It looks like it's a driver issue, but updating all my drivers with Dell Utility and Intel Driver Update Utility didn't fix the problem.
Can anyone please help me?
Thx

Have you updated your video driver lately. Sleep seems to be involved with that driver so perhaps checking to see if an update is available or uninstall and let the system reinstall.
If you go all the way back to a Basic Microsoft video driver, it will not have sleep options either.
Do you have alternate power schemes available you could try?

Thanks for your quick reply.
I have uninstalled and reinstalled the Intel HD Graphics 5500 driver, but this doesn't fix the problem. Still no sleep mode available.
Choosing other power schemes does not affect available sleep modes either.
What else can I do?
