This one isn’t for the faint of heart, so BE CAUTIOUS! Alex was having noise issues with the fan inside his Toshiba M400, so he did what any good mobile geek would do: he hacked apart his Tablet PC and fixed the problem! The write-up isn’t step-by-detailed-step, but the gist of the concept and order of operation is all there. Alex is using the RightMark Clock Utility to monitor his internal CPU temperature as our standard, Notebook Hardware Control, apparently doesn’t support CPU fan control on the M400. Speaking of support: you won’t get any from Toshiba if you attempt this repair as your warranty will be null and void; not null OR void…null AND void. Apparently, there’s a difference between and & or.
