Hello,

I have a new PC build and it spuriously wakes from sleep. I have disabled allow wake up on network which has greatly reduced the frequency of wakeups but it still happens.

Yesterday during waken hours it was happy sleeping for more that 5 hours but again this morning is was alive and bright eyed

powercfg -lastwake gives me the results below

Wake History Count - 1

Wake History [0]

Wake Source Count - 1

Wake Source [0] 

***Type: Device*** 

***Instance Path: USB\VID\_046D&PID\_C517\6&24d8e55e&0&2*** 

***Friendly Name:*** 

***Description: USB Composite Device*** 

***Manufacturer: (Standard USB Host Controller)***

After waking it this morning with the keyboard I did the same powercfg -lastwake and the Instance Path was exactly the same so it that a reliable indication that the wakeup call came from the USB keyboard?

Also I checked the powercfg help but is there a way to discover what time the wakeup occurred?

TIA

    VID_046D&PID_C517 tells me that your wake-up event is being caused by a Logitech (Vendor ID 046D) model LX710 Cordless Desktop Laser Mouse (Device ID C517). These identifiers exist in all devices, both PCI and USB, and are unique to that device for the purpose of automated device identification by device driver installers.

    Laser mouse HIDs are extremely sensitive. They detect micro-movements, caused by sounds you might not even hear from passing automobiles, loud music in other rooms or from outside, and even just from vibrations, such as when you get up and jostle the tabletop, or when you walk across the room and vibrations are conducted through the table and into the mouse pad or into the device.

    Laser mice also have a lot of trouble with porous mousepad surfaces, any mousepad color that isn't non-reflective matte black, and the list goes on.

    Cordless HIDs also typically "ping" the USB dongle which contains a radio transceiver, even if they don't detect any user-input at all, and the activity on the USB dongle might be interpreted as a wake-up signal by your OS.

    Hi Jompra,

    Welcome to Microsoft Community.

    I'm Hahn and I'm here to help you with your concern.

    Yes, it looks like the information you obtained from powercfg -lastwake is indicating that the USB Composite Device with the Instance Path USB\VID_046D&PID_C517\6&24d8e55e&0&2 was the last device that caused your PC to wake up.

    Regarding your question about finding out what time the wakeup occurred, you can use the Event Viewer to check the system logs for power events. Here's how you can do it:

    1. Press Win + X and select "Event Viewer" from the menu.
    2. In the Event Viewer, navigate to "Windows Logs" > "System."
    3. Look for events with the source named "Kernel-Power." You can filter the logs by clicking on "Filter Current Log..." in the right-hand panel and selecting "Kernel-Power" as the event source.
    4. Look for events with an Event ID of 1, which indicates a system startup or wake event.
    5. Check the "General" tab of the event to find the timestamp and details about the wakeup event.

    This should provide you with information about the time the last wakeup occurred.

    You can try to disable the wake feature for your keyboard by following these steps:

    • Press Win+X on your keyboard and select Device Manager.
    • Expand Keyboards and right-click on your USB keyboard.
    • Click on Properties and go to the Power Management tab.
    • Uncheck the box saying Allow this device to wake the computer.
    • Click OK and close the Device Manager.

    This should prevent your keyboard from waking up your PC from sleep mode. If you have other USB devices connected to your PC, you may also want to disable the wake feature for them as well.

    If the issue persists and you suspect the USB keyboard is causing the problem, you may want to try a different USB port or even a different keyboard to see if the behavior continues. Additionally, make sure your keyboard drivers are up-to-date.

    Safe mode starts Windows in a basic state, using a limited set of files and drivers. If a problem doesn't happen in safe mode, this means that default settings and basic device drivers aren't causing the issue. Observing Windows in safe mode enables you to narrow down the source of a problem, and can help you troubleshoot problems on your PC. Start your PC in safe mode in Windows - Microsoft Support

    I hope this helps.  If there is anything not clear, please do not hesitate to let me know.

    Your Sincerely

    Andrew,

    Thank you for that additional data, I had used a Logitech EX110 cordless keyboard/mouse combination although I never used the supplied mouse.

    As quirk would have it the keyboard started to play up even with new batteries so now replaced with an MK345. I started to get the odd wakeup from a Realtek device but now have wakeup disables in Device Manager and I appear to have reliable uninterrupted sleep wake up from the keyboard as intended.

    Thank you for taking time to reply and help.

    I don't get the codes you indicated but I am much more well informed, the computer did not wake spuriously this morning and I don't have a cat (-:

    Using the Event Viewer yesterday with a manual sleep and wake up gave me the following;

    Information 13/01/2024 17:44:32 Kernel-Power 130 (33)

    Information 13/01/2024 17:44:32 Kernel-Power 131 (33)

    Information 13/01/2024 17:44:03 Kernel-Power 107 (102)

    Information 13/01/2024 17:43:55 Kernel-Power 42 (64)

    Information 13/01/2024 17:43:50 Kernel-Power 187 (243)

    EventID 107 was (The system has resumed from sleep.)

    EventID 42 was (The system is entering sleep.)

    I'm posting this to save confusion of others, with your help I can now see exactly when the wakeup occurred and hopefully get to the bottom of this sporadic issue.

    Thank you for your detailed reply, it was very helpful and I learned something today.

    I actually want the keyboard to be a wake up device but now with your tuition I can find the problem and overcome it.
