I had a similar problem before - to stop this from happening Exertis advised me the following:
Devices powering themselves on, discharging when shut down or not holding a charge and/or experiencing difficulties with powering on is a now-known Windows 10 issue. Please follow the steps below to resolve the issue;
Go to 'Control Panel'. (In the search box on the taskbar, type Control Panel, and then select Control Panel)
Select ‘Hardware and Sound’.
Select 'Power Options'.
Select 'Choose what the power buttons do' (found on the left-hand pane)
Select 'Change settings that are currently unavailable' (written in blue above the Power and Sleep button options)
Uncheck 'Turn on fast startup (recommended)'.
Hope this helps
