Laptop switching on and running the battery down from Hibernate
I'm still new to Windows 10 (home), from XP and recently bought a new HP laptop. I always leave the laptop with a full battery and hibernate overnight, with mains power turned off and the lid open. In the past week I noticed twice that the battery was about 80% in the morning so researched and made the changes to try and prevent wake states. Devices don't allow wake, task scheduler, deleting HP bloat, power saving options etc. Since then on Monday morning, the laptop battery was only 1% which I was furious about as I always avoid running a battery down as it causes damage. The battery is also 10.5 hours, and it was only left about that long or less, so it must have been on full power. There was nothing in the event viewer for the time it should have been off. I checked and amended the settings again and made a few more changes. (Including registry settingfor WindowsUpdate AU to 0. Last night I left it plugged in to the mains with a wattage meter. It did not switch on. Maximum watts used remained <1 watt. I have checked the battery and it is fine and works correctly in normal use.
So maybe I already fixed it but just checking if there is anything I might have missed. With an old netbook on XP, although it was never a problem, if I closed the lid or even temporarily turned off the power after hibernating, it would NEVER switch itself back on. It seems the HP with 10 does not do this, although I have not tried closing the lid??? If I have to shutdown rather than hibernate and/or close the lid, I'll have to but surely that shouldn't matter?
If it happens again, I'll know to use powercfg to see what waked it, although I expect it will be undetermined.
Of course, I have no idea why it did not shut down after doing its thing even until the battery was totally flat?
Any ideas? Obviously I'll leave it plugged into the mains until I can trust it. My fear is that it will be ok for a few days then do it again when I turn the mains power off and continue to kill the battery. (I gather 10 likes to reset settings during updates too) Surely it shouldn't be difficult to say switch off and remain off without having to remove the battery!!??
EDIT: One thing not tried yet is turning off "fast boot". I just found where that setting is, so turned it off. Don't know if relevent to this?
