Fix Wireless Connection Problems

Wireless cards in the T410 frequently drop active connections due to issues with power management functions in Ubuntu. Resolve this issue by automatically turning off wlan power management at startup with the following command in the Terminal:

sudo nano /etc/rc.local

Add the following two lines before the exit 0 line and then save the file:

sleep 10
iwconfig wlan0 power off
exit 0

Restart the computer.



Configure Thinkfan

1. Open the Terminal and enter the following command

sudo bash

2. Install lm-sensors with the following command

apt-get install lm-sensors

3. Install Thinkfan with the following command

apt-get install thinkfan

4. Enable fan control with these commands:

echo "options thinkpad_acpi fan_control=1" > /etc/modprobe.d/thinkfan.conf
modprobe thinkpad_acpi

5. Set thinkfan to run at startup by changing START=no to START=yes in /etc/defaults/thinkfan. Edit this file by entering this command:

nano -w /etc/default/thinkfan

6. If you are running Ubuntu 15.04 Vivid Vervet, enable the systemd daemon thinkfan with the following command (this step is unnecessary in Ubuntu 14.04):

systemctl enable thinkfan

7. To customize the temperature ranges and fan speeds that thinkfan uses, edit /etc/thinkfan.conf by entering the following command:

nano -w /etc/thinkfan.conf

8. Scroll to the bottom of this file and change the temperature settings as desired. The defaults are very conservative. The settings I use are:

(0, 0,  65) 
(1, 58, 70) 
(2, 60, 71) 
(3, 62, 73) 
(4, 66, 75) 
(5, 69, 76) 
(7, 73, 32767)

Restart and confirm Thinkfan is running by entering the following command:

service --status-all
