Thinkpad T450s error: thinkpad ec_read_row: failed requesting row

#1 Post by Dobob » Fri Apr 14, 2017 3:17 pm

I have researched the error but can't find any solutions.

I have linuxmint Cinnamon 64-bits 18.

I get the below errors every time I shut down my Thinkpad T450s:

Code: Select all

[13.463404] thinkpad_ec: thinkpad_ec_read_row: failed requesting row: (0x01:0x00)->0xfffffffb
[13.463404] thinkpad_ec: initial ec test failed
[13.512358] thinkpad_ec: thinkpad_ec_read_row: failed requesting row: (0x01:0x00)->0xfffffffb
[13.512358] thinkpad_ec: initial ec test failed
Apparently it has something to do with tp_smapi or something, does that mean I should uninstall it? I read someone got more errors after uninstalling it. Anyone know how to fix this?

HI I am new

I use Mint on my T500 and I do not have that module installed. The module in question is a optional one and is not installed by default. Yes that error is from tp_smapi module not all Thinkpads will support it. Lets see what the output of this command is...

Code: Select all

sudo tlp stat -b  
If the output is not compatible remove it
