Z11-FHX Screen Shake Problem

I have a rather unusual issue with my Signature Z.

My screen shakes.

I don't mean the physical apparatus being wobbly; rather, that is quite secure. I have no issues with the physical build. It is very solid.

I notice, when I come out of sleep mode and am on battery, my screen will "shake" from side to side. I really don't know how else to describe this. It will happen several times, usually with Firefox open.

Has anyone encountered this phenomenon? I really don't know how to fix it, or what to even try to do. It seems to be a temporary issue (it hasn't done it in the last few minutes), but it's enough to tick me off. I really don't have a set protocol to try to replicate the problem, other than to put it in sleep mode.

Does anyone have any thoughts here? I'm curious to see if someone can relate, and if so, what steps were taken to alleviate this small headache.

Thanks,
John

 

I get some very minor shakes in the corners of the screen when I move thecomputer slightly. I don't think its the same as what you are saying but if i move the lid forward and back I will see diagonal lines only in the corners.
I don't think this is the same problem but I have an issue too.

 

Same here. I also have this problems after wake up from sleep mode.
stamina mode 60hz refresh rate -> shake
stamina mode 40hz -> no problem
speed mode -> no problem
It will be fine after reboot
