Brand new Spectre X360. Battery drains 0.8% per hour while Spectre is shutdown. There is ZERO battery drain of spouse's Surface notebook. I have disabled fast start up. USB ports are not in use. This is a serious problem as I leave my notebook off for several days and could drain to zero possibly damaging battery.
Welcome to HP Forums @pvbgolfer,
Thanks for the post. I understand that the battery is loosing power even when the computer is shutdown, is that correct? I would like to provide some suggestions.
Recommend you to install and run HP Support assistant to check for driver updates and BIOS. Refer http://hp.care/2fvNQNc
Run battery test and calibrate the battery if the battery test passes, refer http://hp.care/2fTWp2I
You can also change the power options on the computer to check if it helps, refer http://hp.care/2fU0vbn
Let me know if this helped.

I finally sent my PC back to HP for repair under warranty. It arrived yesterday and the issue appears to be resolved. They indicated the issue was a Firmware and driver update. Based on the number of posts of people with similar issues and the fact that reviewers are now starting to notice the issue, can you raise it within HP. I believe they need to address the issue - perhaps a recall or public posting of what to do to correct the issue.
