 | Idle temps 68C on Toshiba laptop Looking at a 5 yr old Toshiba Satellite A-45 Laptop with an Intel Pentium 4 2.4 Ghz processor. I have vacuumed the rear exhaust openings, and even popped opened the access panel to the heatsink/cpu, and vacuumed the heatsink visibly free of crud.
The bottom exhaust fan spins OK. Not sure if the RPM is correct or adequate to keep it normal temp? This brings me to my question of : Is 68C a normal temp reading for a laptop with NO load or idle?
I am basing this temp reading from CPUID`s Hardware Monitor. Under ACPI: THRM: I get the 68C reading. The Laptop does NOT Bluescreen or crash, and it doesn't seem hot when feeling around the exhaust ports, but it does tend to freeze when multi-tasking. Of course 512MB RAM doesn't help in that regard either.
However, after doing a recovery install back to factory default status, I now get a persistent System Warning: "A problem with the cooling system has been detected. Please turn off the computer immediately, and return it for service".
After ignoring this warning and completely finishing the installation (*all* those Windows Updates including 3 Service Packs etc.) without any problems other than being super slow compared to my rigs, and of course that damn Warning pop up!
I determined rightly or wrongly that the laptop wasn't actually overheating? Maybe just a bad Motherboard sensor causing the alarm? Anyway, I ended up just renaming the culprit file in Windows/System32... just to turn off the Warning! After all, it didn't display any such warning prior to reinstalling back to default with Toshiba`s "Recovery" disc
I have since, loaded many Programs and data leaving the laptop on and running for many hours at a stretch, with NO BSOD`s or crashes.
Any thoughts or insight here Any recommendations or corrections?
Thanks,
Matt |

 | "but it does tend to freeze when multi-tasking."
Based on the other things you said this means that it is sluggish and not that it completely locks up and has to be rebooted? In this case I would agree that the ram limitation could be the culprit.
If it otherwise runs ok and given its age and that there isn't much point in having it serviced I wouldn't worry too much about the warning. If it does start having major problems it would be more sensible to just replace it with a low end new laptop than spend money trying to fix it. |

 | First off, thanks for your reply to my post.
I agree with you in your assessment of the warning error message I am getting, and also that this laptop isn't worth the expense of any service/diagnosis fee.
I wonder if you could possibly give me an idea as to what temp range would be considered normal for this 5 yr. laptop ?
Thanks again

 VegasManAre We There Yet?Premium join:2002-11-17 Schaumburg, IL | reply to mattrixx I have the same CPU in my 7yo laptop and my no load is around 49c. It used to run high 50's to 60 but last time ripped it apart to clean the heat sink I reapplied it with AS5. I also installed Speedfan and changed the fan settings. That might be something you look into if you want to bring the temps down. -- In need of a Vegas vacation.

| I agree with VegasMan. Although asd has a point, really, 512mb ram on an XP system should be adequate, even multi-tasking, though you might consider going to 1gb.
I suspect that you are running hot enough that the CPU is throttling down to a lower speed, which is part of it's built in thermal protection, especially based on the temps that you are describing, as that is right on the cusp of where the CPU should throttle-down.
Since you already did the correct things, such as blowing out the vents and insuring that the CPU fan was properly operating, then the next step is to remove the heatsink/fan from the cpu, thoroughly clean off the old material, and reapply a quality heat sink grease, such as AS5.
I would never let any of my notebooks run at that high a temp. The good thing is that there really is nothing mysterious to fix. If the vents are clear, and the cpu fan runs correctly, then the only culprit at that point is the interface between the heatsink and the cpu. -- Deeds, not words |

I'm not sure but I would think something like the low 60s under reasonable load would be the max I would want to see. I don't like 68 idle. As you say, though, the reading could be inaccurate. I would just keep good backups if there are important things on the machine and use it, as is, until it becomes a pita and you want to trash it. |

 | Thanks to ALL for your comments and insight.
I have installed the latest "Speed Fan", but I`m afraid it isn't that helpful other than as information. This laptop`s MB apparently has meager sensors. There are no fan, voltages, etc. entries listed to monitor or manage.
The more I run this thing the more I doubt the accuracy of the actual temp reading (at least the cpu reading). When under a load, I can hear the fan power up to spin faster RPM but the temp reading never moves from usual 68C. When first turned on the temp reading is ~ 61C
Anyway, I'm not going to risk pulling the heatsink off and reapplying heat paste but take my chances, hoping its just a "bad" sensor. I will continue to watch and run this "hand me down" until it eventually dies.
Thanks again Matt |
