Re: x201 random shutdown...

i have another question...

Why i dont have temperature information in any sensor in tpfc?

I have in other programs like cpuz but in tpfc i dont have temperatures i need use in manual mode.

Thanks

Re: x201 random shutdown...

Sorry for being late in your thread. Unfortunately it doesn't look so good, I'm afraid the motherboard may have an issue, nevertheless there are a couple of things I would like you to try:

 

  • Try booting your X201 from a Linux live distro out of a USB drive (or CD drive if you have an external optical drive or a docking station with opticak drive. See if the problem persists in Linux
  • Are all drivers installed? You're positive that the temperatures are low? How hot does it feel around the top left corner? 
  • Which BIOS version do you have?

Re: x201 random shutdown...

Dear Sir,

 

I have sure the low temperature.

I tried the linux with the same problem.

i have all drivers installed.

My Bios version is 1.40

Why i can see the temperatures in the Hardware Monitor and i cant see in tpfancontrol?

Thanks a lot.

Regards,

Re: x201 random shutdown...

I don't recall having issues with Tpfancontrol in my X201 with Windows. I'll need to check again... Nevertheless, if all drivers and BIOS are up to date and your ThinkPad is switching off at 40°C I guess something may be wrong with the motherboard.

Re: x201 random shutdown...

I think if you vacuum clean the computer it is safest to turn it off and block the fan rotation with a paperclip or similar. The fan is a permanent magnet motor and it will run as an alternator and may fry some electronics.

 

I noticed in the emergency application "TPFanControl", in the ini file, the default setting highest fan speed value is 128. This value has a special meaning and hands speed control to the BIOS. We already know BIOS is not handling the fan properly so handing over should really only be made if fan control is not working at all.

 

In my 201X TPFanControl is started at system boot with the following values in the  TPFanControl.ini

 

Level=22 0
Level=45 1
Level=50 2
Level=53 3
Level=55 5
Level=65 7
Level=75 64

 

Valus can be fine tuned in manual mode watching the CPU temperature at each speed level 1, 2, 3, 5, 7 set. All done while computer is idle.

 

Each temperature threshold is set some degrees above final temperatures so you know the assigned speed is capable of cooling down below the assigned threshold. Have the highest speed 64, kick in at a level where a sudden high load is met early.

 

Notice fan speed is NOT a linear scale {0..7}. In my case only values {0, 1, 2, 3, 4, 7, 64 and 128} make a distinct change. 

 

Since TPFanControl is run by the OS it can be held back by some runaway application and unable to control the fan. Having the 128 value turn over to BIOS is no guarantee as it requires the TPFanControl to be executing. And if it is executing it may just as well handle the fan. The only occasion is if it is somehow executing but unable to control the fan. Not sure if that can ever happen??

 

Best would have been if Lenovo had interest in their product and have fixed the BIOS ten years ago.

 

For fun - I have been thinking of installing a tiny Arduino board into the laptop and have it read the sensor and spin the fan. The unused PCEXPRESS 2.0 slot has plenty of room for something like this: https://www.tindie.com/products/imrehg/pcieduino/
