Computer intermittently wakes itself up from sleep mode on its own!

[Moises2018]

My computer intermittently wakes itself up from sleep mode on its own. This is an intermittent issue I have noticed.

Sometimes after a few moments after being put to sleep my computer wakes up by itself, after that happens usually I can put it back to sleep and it will stay asleep but sometimes I have to do it 2 times before it stays asleep.

Does anyone have any ideas or suggestions as to why this could be happening or what I can do to remedy this??

Thanks!

Usual culprit is a USB device...mouse mainly (or so I've found). If you want to test the theory, set your power button to set the computer to sleep (via power options in Win7). Disconnect mouse, hit button, computer should sleep.

What I've tried so far was to power off the USB mouse (has a power button on bottom) and then with keyboard selected sleep... Would this be the same or do I need to actually disconnect the mouse from my computer to test?

The switch should usually do, hmm. What other USB devices are there? USB devices would be my first concern, second would be programs/scheduled wake-up programs such as set defragmentations, etc.

Do you have an external 2.0 USB Hub in the mix? Have always found that isolating the USB 2.0 Luney's away from the same hub as an active USB 3 component, helps with the False Sleep problems.

Intel Smart Connect ?

If your computer is on a Windows Network with other PC's running, that may interrupt sleep too.

In Administrative mode of a command prompt run "powercfg -energy"

It will create a report which will indicate problems with sleep mode in html format.

Also check event viewer for times when computer wakes up to see what started it.

The one which i found in tthe same situation was to disable all wake on lan features including magic packet (from device manager). That fixed it for me.

Hello,

Thanks for the replies… I don’t have a USB Hub. I do have a Logitech G700 Mouse and G510 Keyboard (both USB). I have a Cyberpower UPS with has a USB connection… that’s it…

I don’t have Intel Smart connect installed…

I do have another computer on my home network but its turned off most the time when I have noticed this…

I will try POWERCFG –ENERGY for the report and will also try to disable the LAN wake up option with Magic Packet.

Thanks again everyone for the suggestion, will give it a try and report back once I have a solution.

Sometimes there are programs that like to check for updates in the middle of the night. I had that problem a while back. And there is a way to see what is waking the system up...

One way to find out what is causing a wake-up problem is provided by the command line. Open a command prompt with elevated privileges and enter this command:

powercfg –lastwake

The last device that woke up the system will be shown

To find out which devices are enabled to wake up the PC, enter this command

powercfg -devicequery wake_armed
