Add a "Don't remind me again" when there is no power management options selected

Normally I don't use power management options,the reason is because that way I can use the NVIDIA card in a VM,if I use bbswitch or PCI power control VFIO drivers can't detect the NVIDIA card.

When I have not power management selected and I switch modes,there is a message telling me that I may have poor battery life.

But for some reason this is false for me.I have a 1050 Ti Mobile and the NVIDIA card in Integrated Mode can be powered off itself without using any tool,and since I have automatic logout this popout is a little annoying because I have to press ok to then logout.

So I propose a little change,a checkbox in the popout saying that don't remind me again would be useful.

This could be useful. I would add this checkbox to the settings too. But I currently running out of time. But feel free to send a PR.
