[DO NOT MERGE YET] Laptop MultiFix

Bugfix 1 - Fixes #5570
Also de-copypasted charger code, as i had the opportunity.
<hr>
Bugfix 2 - Fixes #5553
Also added ability to create "hidden" files which won't show in program/file list of NTOS.
<hr>
I intend to fix all four reported laptop issues. Remaining: #5569 #5572
Well, it can always be changed. I think it's better hidden, as certain channels (Entertainment channel) are probably suposed to be some kind of TV, kinda weird to watch TV via program named "camera viewer" (or whatever is that thing called).
