I have downloaded tp_smapi module for my Thinkpad T500 using the steps in ThinkWiki and ran make. it encountered no errors

root@Forge:/storage/Repository/git/tp_smapi# make install HDAPS=1 FORCE_IO=1

But when i tried to view the status of the battery using tlp, it shows as not loaded/installed:

root@Forge:/storage/Repository/git/tp_smapi# tlp-stat -b
--- TLP 0.7 --------------------------------------------

+++ ThinkPad Extended Battery Functions
tp-smapi   = inactive (kernel module 'tp_smapi' load error)

/sys/class/power_supply/BAT0/status                         = Full

I have followed the steps provided on the sites to the best of my knowledge, but am unsure as to why the module is not installed.

  • OS: Xubuntu 15.04 LTS
  • Module code: tp_smapi-GitHub
  • Kernel: 3.19.0-18-generic (x86-64)

Reset to default

Many instructions at thinkwiki.org are very outdated.

Just install the package from the Ubuntu repos:

sudo apt-get install tp-smapi-dkms

(as described in TLP's docs too)

  • i have tried to do so & restarted, system says "tp-smapi-dkms is already the newest version."and tlp-stat shows the same error message about tp_smapi load error.

  • Lets see what happens if you load by hand: sudo modprobe -v tp_smapi force_io=1 and don't reboot afterwards, just check with sudo tlp-stat -b

  • I am getting a the following error message: sol@Forge:~$ sudo modprobe -v tp_smapi force_io=1 insmod /lib/modules/3.19.0-18-generic/extra/thinkpad_ec.ko modprobe: ERROR: could not insert 'tp_smapi': No such device or address

  • I have found the issue - there is no current conf file /etc/modprobe.conf, I have found that we need to create a new conf file in /etc/modprobe.d folder which i did & added the load with options for both modules. options thinkpad_ec force_io=1 \n options tp_smapi hdaps=1 force_io=1
