Hibernate mode

I often don't shut my laptop down at the end of the day and have used hibernate mode instead. It has worked great for years until a month or two ago. I would turn off wi-fi and put it into airplane mode before putting it into hibernate mode. All of a sudden when I would put it into hibernate I came out in the morning and the fan was running and was definitely not in hibernate. The next day I paid more attention and when I put it into hibernate mode within a few seconds the login screen would appear. Sometimes after trying it a few times it would go into the hibernate mode but often it wouldn't. Shortly after this started Microsoft did an update and then hibernate once again worked as it did before but then within a couple of weeks the problem returned. I'm not sure if it was a result of another Microsoft update or not but would like to find a solution to the problem.

Thank you

    Hello D Myr,

    It sounds like something may be waking the laptop immediately after it enters hibernation.

    After it returns to the sign-in screen, right-click Start, open Command Prompt (Admin) or Windows PowerShell (Admin), and run:

    powercfg /lastwake

    This may identify the device responsible. You can also run:

    powercfg /waketimers

    If a device is listed, open Device Manager, find that device, select Properties > Power Management, and clear Allow this device to wake the computer. Common causes include the Wi-Fi adapter, mouse, keyboard, Bluetooth, or a USB device. You can also temporarily disconnect USB accessories and test hibernation again.

    Also, check the laptop manufacturer’s support page for the latest BIOS, chipset, and power-management drivers. Manufacturer drivers may work better than generic drivers delivered through Windows Update. Restart the laptop after installation, then test Hibernate again.

    Let me know how it goes!
