MAJOR PROBLEM WITH PUPPY LINUX!!!!!!

[KG4RUL]

I was setting up FLDIGI under Puppy LINUX when my laptop shutdown on an over-temperature condition. I had noticed that the body of the unit had seemed rather warm and was waiting for the cooling fan to come on. Apparently Puppy does not know how to control the fan at all!

I rebooted it as a WIN XP Pro machine and noted that the cooling fan came on and ran for over a 1/2 hour before the unit cooled down. I don't know if this will be a problem on other laptops but, it is something to be aware of.

Here is a link the the distribution called


Digipup (http://www.w1hkj.com/flpuppy.html). It has fldigi preinstalled on it. I have this running on my laptop. Perhaps I will eventually set up the laptop with a wireless card for networking. However, I do intend to use it with my Alinco DJ-S41 for psk31 operation in the near future. I sincerely hope this helps and I am sorry that my previous was in error.

I have not yet had an overheating problem with digipup and it already has fldigi preinstalled on it. That is the only reason I suggested it. Other than that, I am uncertain if the pupget/dotpup package system can provide a solution to your overheating problem. Wish I could be of more help. Sorry.

Did some testing on a couple of live distros I have in-house. So far:

Puppy Linux - No Fan Control
Mandriva - No Fan Control*
KUBUNTU - Controls Fan
KNOPPIX - Controls Fan
PSKLIVE - No Fan Control (Mandriva based)*

* Two Mandriva based systems - one controls fan and one doesn't! http://www.qrz.com/iB_html/non-cgi/emoticons/rock.gif

Out of curiosity, can't you somehow get control through a BIOS setting of some sort? - Seems like an all to important thing to leave just to the O/S.

Hello.

I have read about this before.
The Intel chips have CPU temp shutdown, AMD chips do not.
There have been cases where the OS has crashed on AMD laptops and the motherboard smoked.
Remember, powerdown is a soft key function and on a loptop simply removing power does not deenergize it, the battery is still providing power and if the thing is very hot removing the battery may not be an option.

Yes, the first generation of a particular line of AMD CPUs had thermal protection problems (AMD K6? it's been awhile). But that was back in the days of the original 'Pentium' class chips and has been long fixed by AMD.

One of the hardware review sites back when (Anandtech? Tom's Hardware?) had a video showing the removal of the CPU heatsink from running systems using Intel and AMD CPUs of the time. At that time the AMD CPU literally destroyed itself before it would shutdown. The Intel system just locked up. There was so much hoo-hah over that, AMD not only fixed it in that CPU line, but replaced some CPUs. It hasn't been an issue for quite some time now (years).

I repair laptops as part of my 'day job'. One of the more common failures is the CPU heatsink assembly. Either the 'thermal pad' separates creating an air gap between the CPU and the heatsink or the fans fail. Almost every 'pad' equipped laptop that's had heat issues has benefited from a simple clean up and proper application of a good heat sink compound. You'd likely be surprised at how many fans simply die. Loss of lubrication, dirt build up, seized bearings, etc. For such a critical component, many manufacturers really cheap out on their CPU fans. I won't even go into the 'felt' blankets that 'grow' in many heatsink fins - ugh. I'd be way more likely to suspect that kind of failure before I suspected any particular OS or *nix distro of not running a CPU fan.

CPU fan control is OS independent on every laptop I've ever dinked around with. I've never seen or heard of a laptop that was dependant on an OS feature/component to run the CPU fan. Can't say there aren't any out there - but in my 7 some odd years working on 'em, I ain't seen (recognized?) one yet.

No idea at all. From Google:
One problem and fix (http://www.murga-linux.com/puppy/viewtopic.php?t=16816&sid=def371bc60b169d331de08202403414f).
