"I've been hearing a strange noise from my laptop recently. It seems to be coming from the rear-right corner, where the power supply connects. It's quite quiet, and sounds like a cross between a 1990's modem and an old HDD working hard. When I disconnect the power supply, the sound stops for a few seconds, and then starts again." This is a citation from another user who posted here and resolved this issue with an update for the chipset driver. I've updated but it dosen't work. The sound is still there. What can I do more?
