This page documents configuration and troubleshooting of the IBM ThinkPad T42. The [http://www.thinkwiki.org/wiki/Category: T42 ThinkWiki page] is an indispensable and easy reference.
See the [[Beginners' Guide]] for installation instructions.
Add '''thinkpad_acpi''' to your MODULES array in {{Ic|/etc/rc.conf}}
See [[acpid]] and [[laptop]] for more information.
See http://www.thinkwiki.org/wiki/How_to_make_ACPI_work for more thinkpad specific information.
==CPU frequency scaling==
See [[cpufrequtils]].
==Suspend and hibernate==
See [[pm-utils]].
The MiniPCI slot on the T42 usually comes with 1 of 6 wireless cards, 3 by IBM and 3 by Intel.
===The IBM Cards===
* IBM 11b/g Wireless LAN Mini PCI Adapter (use [[Wireless_Setup#madwifi|madwifi]])
* IBM 11a/b/g Wireless LAN Mini PCI Adapter (use [[Wireless_Setup#madwifi|madwifi]])
* IBM 11a/b/g Wireless LAN Mini PCI Adapter II (use [[Wireless_Setup#madwifi|madwifi]])
You can use the atheros madwifi's ath_pci module (Package: '''madwifi'''). or the newer ath5k module (since kernel 2.6.27). However I used the former since at that time it was the most stable and had fully functional wpa encryption. For the ath5k modlule, please read [https://wiki.archlinux.org/index.php/Wireless_Setup#ath5k this]. Otherwise to load the madwifi driver, type:
{{bc|# modprobe ath_pci}}
If using ath_pci, you may need to blacklist ath5k by adding it to the MODULES= array in /etc/rc.conf, and subsequently prefixing it with a bang (!):
MODULES=(ath_pci !ath5k forcedeth snd_intel8x0 ... ...)
{{Box Note|If despite trying everything the wireless still doesn't work, try a reboot!|}}
Installing these madwifi drivers is common; consult the main [[Wireless Setup]] document for detailed instructions, and the ThinkWiki pages[http://www.thinkwiki.org/wiki/Category:T42] for Thinkpad specific instructions.
===The Intel Cards===
To configure the Intel cards see [https://wiki.archlinux.org/index.php/Wireless_Setup#ipw2100_and_ipw2200 here].
If an Archer has experience with a T42 that uses the Intel PRO wireless card, please modify this document to include information about:
* Intel PRO/Wireless LAN 2100 3B Mini PCI Adapter (use [[Wireless_Setup#ipw2100_and_ipw2200|ipw2100]])
* Intel PRO/Wireless 2200BG Mini-PCI Adapter (use [[Wireless_Setup#ipw2100_and_ipw2200|ipw2200]])
* Intel PRO/Wireless 2915ABG Mini-PCI Adapter (use [[Wireless_Setup#ipw2100_and_ipw2200|ipw2200]])
