Precision 3510 powers off instead of sleeps

My Precision 3510 will not sleep or hibernate regardless of how I attempt it.  If I click start, power, sleep, it just powers off.  I've set the Lid Close mode to sleep when on battery and it just powers off.  I've set it to go to sleep after 20 minutes when on batter, and it just powers off.  I've looked at the BIOs and sleep mode, or whatever it's called, is enabled.  I've run throught the FN diagnostics and they show no issues.  This is running Windows 10 that is fully up to date on patches, and the firmware/BIOS on the laptop is completely up to date.

How do I get this thing to sleep?

RE: Precision 3510 powers off instead of sleeps


When did the issue start? Were there any bluescreens / system crashes? Does hibernation / shutdown and restart work fine? Does this happen with or without the adapter connected? Did the issue start after any recent updates?

If the system was working fine earlier, then perform a system restore to restore the machine to an earlier point where it was working fine -

Restart the system and check in safe mode - 

Create a new local admin account and check -

Manually reinstall the chipset drivers and check -

If the issue is still not resolved, uninstall the video driver - restart the system and check if it works. If yes, then reinstall the video driver from the vendor site - or as required. If you are unable to find the drivers from the vendor site, then send me a screenshot of the device manager with display adapters expanded and I shall provide the driver links required.

Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Let us know if you have any other queries.
