    Thinkpad Power Savings

So here is the deal.

I have a X1 Carbon 5th G with a 6300U in it. I can get about 5 to 6 
hours with apmd and obsdfreqd enabled. Works good.

I have a X1 Yoga 4th G with a 8365U in it. Can get about 4 hours out of 
it with just apmd enabled. Enabling both causes issues. I end up 
draining the battery quicker. Between the two there is something either 
causing drain or it's the cpu arch.


Does anyone have experience with thinkpads?
