"dmesg" and /var/log/messages will give you all the gobbledygook you would ever want. > 2) I looked at the service manual for my T61 and cannot figure out the > drawings.

You do not have the connector or the tools, and replacing the whole motherboard is a complicated job. However, chances are your problem is a bit of junk on the connector or a little corrosion, and you do not need to do nearly as much disassembly to open up the machine and expose the connector for cleaning. The IBM HMM service manual describes the steps. I will defer to Galen or others for the best way to clean a connector. I usually use a pencil eraser, Q-tips, isopropyl alcohol, and a paint brush. Someone more skilled than I might do this just by reaching six inches into the drive bay of the intact machine. An even easier approach is to buy a USB2 DVD drive, and use USB flash drives for stuff you want to move fast. I bought a used USB2 DVD drive for $25 at ecoBinary in Beaverton. They may have them at Free Geek, Green Century, and other Portland places. New is easy, but where's the adventure in that? You do not need to buy a new computer. You can buy a used T61 for $100 to $200 on eBay or Craigslist. There are two for sale on Portland Craigslist as I write. Even more will come out of the woodwork on Craigslist if you post a "wanted" request, especially with people scrambling for money to pay taxes, or who have imprudently pre-spent their anticipated refund. When you buy a Craigslist machine, bring an Ubuntu Live CD for testing, and run a minute or two of the memory test, first. Most of the newer Thinkpads, even the business-class machines, are not as sturdy as the old ones. I like to keep a couple of backup spares of the laptops I use, along with spare keyboards (which I wear out), a spare hard drive, and plenty of AC adapters and docking stations. All this stuff is way cheaper for 5 year old designs, and it will last practically forever on a shelf. The best part of keeping identical spare laptops with Linux is that moving hard drives takes minutes. If the hardware and graphics drivers are the same, this Just Works, unlike the mother-may-I mac and windoze serial-number-sensitive crap. It takes me longer to modify the MAC ethernet hardware address in my DHCP server tables. If you do backups properly, you can even clone a new hard-drive from them, so you can clone a whole machine from last night's backup and be up to speed in a few hours at most, after the complete loss of your working machine. Fixing a hardware problem in Linux is much easier than proprietary OSes, and mastery of your own hardware brings the same satisfaction as mastering your OS does. If you can fix a house, you can learn to fix a laptop.
