Default Laptop waking up when closing the lid

Use a Toshiba Satellite L750, upgraded from windows 7 to windows 10 several weeks ago.

Having a problem where when the lid is closed the computer will go to sleep, like all the power settings are set to, but after several seconds will wake up again.

Tried with deactivated touchpad, no mouse attached, and no internet connection, and still does it.

Looked on the powercfg -lastwake, and says the last device to wake it up was the power button.

Any help please?

Does it say that it is ACPI power button or just power button? I'm pretty sure that they are different.

The ACPI interface can start your systems so check your BIOS/UEFI settings, e.g. turn off Wake on LAN.

Check what can wake your computer. I normally just have keyboards (as use a docking station) and mouse:
powercfg /devicequery wake_armed

Check that automatic maintenance is turned off.
Control Panel\System and Security\Security and Maintenance\Automatic Maintenance

As you didn't upgrade from Windows 8.1 or have up-to-date drivers from Toshiba then I'd also suspect a driver issue if nothing obvious turns up.

I had a look to see if I could get more specific information about the difference between power button messages. I didn't find anything definitive.

Anyway, the power button reported can represent system initiated events other than the user pressing the power button.

I found a number of people with similar problems having older systems that they've upgraded so the driver issue is a real possibility.

You can also check that you don't have any wake timers or programs (e.g. a print spooler) requesting that your computer not go to sleep automatically:
powercfg /waketimers
powercfg /requests

Your waketimers are generally set by scheduling so go the Task Manager or the application to turn them off.

If there are any requests then there is a command to override them. See the powercfg reference or ask for more help if you need it.
