<hr />
<div>[[:Category:T21]]<br />
== Wake On Lan with Ubuntu 9.04 (Jaunty Jackalope) ==<br />
Finally Wake On Lan (WoL) works on my old T21 Thinkpad. I spent a few days with Google and here are my results for Ubuntu 9.04 (maybe working with other versions).<br />
<br />
==Wake On LAN from shutdown ==<br />
There are a lot of tutorials what to do:<br />
* Enable Wake On LAN in the BIOS<br />
* edit /etc/default/acpi-support<br />
* edit /etc/pm/config.d/00sleep_module<br />
* enable in /proc/acpi/wakeup the devices<br />
<br />
==Wake On LAN from suspend==<br />
This was the hardest step to get this activated. Sometimes it worked on my T21, but after changing the haddisk Wake On LAN didn't work anymore. This surprised me a lot, because I didn't change any configuration files. The solution worked for me is:<br />
<br />
lspci -nn | grep Ethernet<br />
00:03.0 Ethernet controller [0200]: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 [8086:1229] (rev 09)<br />
<br />
shows on which PCI bus the ethernet card is working. In my case (first two digits 00) PCI bus 0 and the identifier number is 8086:1229.<br />
Now with the command (replace the zero with your PCI bus):<br />
<br />
sudo pci-config -B 0<br />
Device #1 at bus 0 device/function 0/0, 71908086.<br />
Device #2 at bus 0 device/function 1/0, 71918086.<br />
Device #3 at bus 0 device/function 2/0, ac1b104c.<br />
Device #4 at bus 0 device/function 2/1, ac1b104c.<br />
Device #5 at bus 0 device/function 3/0, 12298086.<br />
Device #6 at bus 0 device/function 3/1, 000c115d.<br />
Device #7 at bus 0 device/function 5/0, 60031013.<br />
Device #8 at bus 0 device/function 7/0, 71108086.<br />
Device #9 at bus 0 device/function 7/1, 71118086.<br />
Device #10 at bus 0 device/function 7/2, 71128086.<br />
Device #11 at bus 0 device/function 7/3, 71138086.<br />
<br />
I found my network card as device #5, the last number is the identifier number in different order (8086:1229 becomes 12298086)<br />
Now put the device to Sleep when changing the power state to S3.<br />
sudo pci-config -B 0 -#5 -S<br />
<br />
And now run <br />
sudo pm-suspend<br />
and try to wake up your T21 with Wake On Lan from a different machine.<br />
<br />
If it is nor working try <br />
sudo pci-config -B 0 -#5 -S<br />
sudo pci-config -B 0 -#5 -W<br />
before sending the machine to suspend. This workaround works fine for me and now I am able to wake up the T21 from suspend over LAN.<br />
<br />
{{HINT|Add your model to the category if this workaround works for you.}}</div>Dider
