Is the electrical noise a high pitched whine? Coil whine? Every Intel laptop I've used has it. It's supposedly due to power saving going on and off. At least on my ThinkPad, disabling power saving (ie running the CPU at full power all the time) made it go away. I think I may have developed tinnitus from it. It's unbelievably unprofessional. 'Course, disabling CPU power saving modes kill battery, but my T440p never got much life to begin with (I get maybe 70 minutes max now, down from around 2 hours. But I'm running VMware for everything, so perhaps that hurts.)

My laptop (a Toshiba Satellite) has an annoying level of coil whine. If it's from power saving, it's GPU power-saving state related, not CPU. It's not noticeably affected by turning off CPU power saving modes, at the very least. It's most noticeable when scrolling image-heavy webpages, or with pretty much anything that ends up with framerates in audio frequencies. Older versions of Dwarf Fortress on the menu screen, for instance.
