Battery Drain

I have a cheap Linx 10 Notebook, quite pleased with it generally but when I first got it about a year ago the battery would drain to nothing over night. I altered some of the power settings and solved the problem, or though I had, but after this latest Windows 10 update the problem has recurred, trouble is I can't remember what I did last time!
I have done some Googling and it has been suggested that it might be the Fast Startup option causing the problem. I have disabled this ans will try later to see how it goes.

Solved the problem by disabling "Fast Start Up".

Glad to hear it Purwell , always interesting to learn in case we ever need to do the same.

I spoke too soon, it's done it again, very frustrating because it means I have to carry the charger with me.

Just found this so will give that a try.

 
settings -> system -> Power & Sleep, click on 'additional power settings'

on the left click 'choose what the power buttons do'

untick 'turn on fast start'.


however,


on mine I simply turned off the wifi when asleep, that seems to have prevented the battery drain.

settings -> system -> Power & Sleep, under network connection  untick 'on battery power, stay connected to network while asleep'


sometimes I have to turn on the wifi again when I wake it, by clicking on the icon then wifi button.

Finally got this sorted after lots of Googling. 
It seemed to be a common problem with Linx machines but they blamed Windows 10 and to be fair it happened to me after the latest update.
I downloaded and installed the latest Intel driver updates and also ran a fix that I found on the Linx site, had to reboot several times and eventually it was sorted but I don't really know exactly what the problem was!

I'm still using this lap top but thinking about another new one.
