Why Won't My Dell Laptop Go To Sleep?

[Doofus]

Inspiron 7548. 3 or 4 years old, running Windows 10.

No matter what I do with the power settings (its currently in 'balanced' default), the screen won't turn off and the laptop won't go to sleep. It's plugged in.

I've fked about with advanced settings over the past three days and nothing makes any difference. It works fine and as expected on battery.

It's getting on my tits. What's wrong with the piece of crap?

Been into the additional power settings?

Has it ever worked?

I’d maybe start with a bios update and chipset drivers

I think so.

Caffeine running?

Have you unchecked the wake from sleep box on mouse settings and on your network adapter settings.?

My work E6430 has just started doing the same. Close the lid and it keeps running. I'm giving it to the tech and work today to sort so if its an update of some sort I'll post here.

Me no understandy. If Caffeine is a piece of software, then I don't think so, as I've never heard of it.

Not that I know of. I'll try that.

Would that stop the screen switching off? The settings are screen off after 10 minutes, sleep after 30. It does neither.

Incidentally, I don't know if it's related, but if I have a screensaver active, it doesn't kick in (yo).

I don't have this problem but a quick browse of the web suggests you are not alone and the screen saver not working is related.

You can go to WIN+X , run Command Prompt (Admin) from there, and enter: powercfg -requests

This should tell you what's keeping the system online.

Within the same command prompt try running System File Checker (SFC /scannow) to see if there are any file issues.

You could also unplug all peripherals to see if something is keeping it online?

One final suggestion, create a new user account and login with that account to see if you get the same issue?

Thank you for that. I'll try this.

Also perhaps unrelated; when I plug in a Logitech 'unified' mouse, the built-in touch pad stops working, even though it's been set to 'not disable'

Yes. Any signal from the mouse or lan will reset the sleep timers back to zero and so it never gets to 10 minutes.

I have a setting called 'Sleep on WoWLAN Disconnect' which was Enabled, so I've Disabled it. Going to have some lunch, then I'll see what happens.

Should I do anything with "Wake On Magic Packet" or "Wake On Pattern Match"?

Sorry caffeine is software yes.
Typically used to keep the work computer ‘awake’ while cutting the grass etc

Still no understandy

It's not a work computer, and it's not on a network.

powercfg -requests

DISPLAY: None
SYSTEM: None
AWAYMODE: None
EXECUTION:None
PERFBOOST: None
ACTIVELOCKSCREEN: None


System File Check running now....

[Doofus]

Windows Resource Protection did not find any integrity violations.

The only peripheral plugged in is a unified mouse, so I'll unplug that and see...
