Hi, I have a Toshiba Satellite notebook having a problem with shutdown due to overheating. I am trying to monitor CPU temperature of this Celeron M 340 (1.5 GHz). I am hoping eventually to find the source of the overheat. FYI, this laptop has been to the warranty shop 3 times already and the source of the problem obvious has not been located. In order to determine the CPU temperautre, I have used MMobile, Intel Thermal Analysis Tester, Notebook Hardware Control and none of the program gave me a temperature nor votlage reading of the CPU. In all cases, the HDD temperature seems CONSTANT under all conditions!? I am NOT sure if it is monitoring at all. After these failures, I tried Everest and got some CPU read out (at least for the voltage of the CPU). It is suppose to be 1.8V but it shows 1.4V!? Anyways, I am trying to figure out HOW to read the temperature and the voltage of the CPU so I know truly what the internal temperature are for the Celeron M processor. Here is a partial output from EVEREST HOME EDITION: *************** CPU Properties: CPU Type Mobile Intel Celeron M 340, 1500 MHz (15 x 100) CPU Alias Banias-512 CPU Stepping B1 Instruction Set x86, MMX, SSE, SSE2 Original Clock 1500 MHz Engineering Sample No L1 Code Cache 32 KB L1 Data Cache 32 KB L2 Cache 512 KB (On-Die, ATC, Full-Speed) CPU Physical Info: Package Type 479 Ball uFCBGA / 478 Pin uFCPGA Transistors 77 million Process Technology 6M, 0.13 um, CMOS, Cu, Low-K Die Size 83 mm2 Core Voltage 1.356 V (?!?!?!

Sigh...

If your CPU was running at 1.8v, then it WOULD overheat...it might even fry! Your M 340 is designed to run at 1.356v. See page #28: http://download.intel.com/design/mo... Check for: - improperly installed or dust clogged heatsink - failed or dust clogged cooling fan - dust clogged intake/exhaust grilles - overvolting (your CPU appears to be at the correct voltage though)

>> Check for: - improperly installed or dust clogged heatsink - failed or dust clogged cooling fan - dust clogged intake/exhaust grilles - overvolting (your CPU appears to be at the correct voltage though) << Yeah you are correct in the voltage of the CPU. Maybe I should undervoltage it?! But I can't seem to SEE the CPU voltage or the temperature. Is there another software in addition from the ones that I have used thus far? I have used MMobile, NHC, Intel Thermal Analysis Tester and Everest and NONE of them gave me a real-time temperature reading. Or is the laptop that I am analyzing simply lack the utility for it?

Try mobile meter, use a google search. This will monitor cpu temps as well as hard drive temp. This program will only run under win xp and will not fully work on desktops. This program was designed for laptops, you can also change the translucency so you can leave it open and still see and use your work and watch your temps.

I have found this to monitor my Toshiba: http://www.hmonitor.net/ Try it out - It's the only one I found that works. I had a problem due to overheating, and it seems like vacuuming my computers heat sinks did the job.
