I'm Greg, an installation specialist and 9 year Windows MVP, here to help you. What else can I look for or try? I see many other people with the same issue, but haven't found anything that solves the problem. It has only been recently that this problem has come about which makes me think it might be related to a Windows Update that occurred. Nothing has really changed on this laptop in terms of hardware, software, etc and sleep mode always functioned perfectly fine. I only have sleep and hibernate options as shown in the picture (no hybrid versions) : Nothing significant has been changed on this laptop that corresponds to when this problem started. using hibernation works perfectly fine - only sleep mode has a problem tested with all external usb unplugged just for sake of testing and nothing changed graphics is running the latest driver (has not changed in years so this cannot be the issue) bios is most current, default, etc (it has not changed in years so this cannot be the issue) This happens when the it is plugged in - not running on battery - and even then I just purchased a new battery within the last year so I can't believe this to be power related. Kernel-Power with event id 41 which just means it shut down unexpectedly. The only thing of any relevance I am noticing in the event viewer is : and when I resume or 'wake up' the computer it just shuts down.

I have been running Windows 10 for some time I have to believe this is coming from a recent Windows Update. Seeing as how this never happened before and Within the last few months the laptop can no longer resume from sleep mode and shuts down unexpectedly. Have had this laptop for many years now and installed Windows 10 (from Win 7) when it was made available.

Windows 10 shuts down after sleep
