Toshiba laptop overheating

I have a Toshiba Satellite L455D laptop that has suddenly decided to overheat. It hasn't been used in a long time, so figure the heat-conducting paste under the cooling tower (or towers) has dried out. I ran Speedfan on it and it gets up to 178 degrees F and shuts itself off. I know how to clean out computers and how to reapply paste between the cooling tower and the CPU, etc.--I even have the paste. Speedfan also shows NO fans working, but you can hear the main fan (the only one?) turn on and feel the hot air come out of the vents on the left side of the computer. The problem is I can't get the silly thing apart. I've taken out every screw I can find; under where the battery was, inside the removable plastic covers, etc. There must be some screws hiding that I can't see, but where? Anybody have any experience with this brand and model?

Go to Toshiba's website under support and see if there is a downloadable PDF service manual. There may be some screws underneath the keyboard that need to be removed.

Hope this helps.

 

Toshiba didn't have a service manual for this computer on their website, but your post got me thinking. I did a search on "how to disassemble a toshiba satellite L455D" and got this URL:

Sure enough, instructions. Hopefully I'll be able to put it back together now!
Thanks for getting the thought process started.

I got my Toshiba Satellite L455D back together, and it now runs cool... at least it runs cool if 114-116 degrees F is cool (I got a blue checkmark in SpeedFan)...but now it won't boot at all. So, you're wondering, how did I get SpeedFan to work if it won't boot?

When I first started it back up after reassembly it would still boot in safe mode (which is when I ran SpeedFan) but not in normal mode. Black screen OR background screen with no icons. In any case, I decided to do the "computer repair" routine. Selected that option during boot and started the process only to have it crash and tell me there was an error. OK, I figured I'd just start it over. Oops. Now it starts to boot then crashes with an error that says "Bootmgr missing. Ctrl-Alt-Del to restart." Ctrl-alt-Del just gives me the same error over and over. The boot manager must be important, eh? Duh. So, now what? Looks to me like an OS re-install, only of course this computer, like all computers these days, didn't come with an OS CD. At least I didn't get one with the computer, which is used. Also, the previous owner either didn't do the boot CDs or didn't give them to me and there is no contact there anymore, so, what to do? Buy Win7 and re-install or is there another way?
