Well, i've gotten my Thinkpad back after two additional repairs, and now all the hardware actually works (physically at least.)  I've been doing some research on the Core Duo (not Core 2 Duo), and it seems that the processor is closer to the Prescott than it is to the Pentium M.  I'm not a microprocessor architect, so i'm really relying on other people's opinions here.  The issue, as i understand it, is that Prescott favors the sse3 (aka pni as seen in /proc/cpuinfo) for floating point operations as opposed to the older Pentium instructions.  Both will work, but the Pentium-m doesn't have sse3/pni, so some floating point operations will take longer.  This has larger implications on the compiler optimizations than it does the kernel, but appearantly Pentium-4 would be a bit better than Pentium-M for the kernel, and prescott for the compiler.  I'm going to change the wiki to reflect this new information.  If you happen to have any more information, or you believe this to be innaccurate, feel free to make modifications.  Also if you have more info about the core duo and it's kernel optimizations please post it on this talk page.  What it boils down to, i think, is that nobody really knows yet what the correct informations is for sure.  There's definitely a lot of conflicting information out there.

Revision as of 23:08, 21 December 2006

My intention is to finish this page to the point that i have my own notebook to when i can find time in the next couple weeks. Although most of the information here can be found in other places in Thinkwiki, some of it has been a process of trial and error. Getting this notebook operating smoothly has been quite challenging simply due to the lack of comprehensive information in one place for the Slackware distro. After i finish the full guide, i intend to HOPEFULLY start moving things out of the Non-Working column and explain how the fix was achieved. If you find errors in grammer, facts, or methodology, by all means. . .

It looks like i may be without my Thinkpad for a while. . . i've run into a problem with which i don't have a solution: When i have headphones plugged in i get horid static if i play anything over ~64kbps (no idea why), but this is unacceptable to me, so i'm going to have to have it repaired. Anyway, enough about my problems, i'm going to try to continue adding to the page from some notes that i have, but i may hit a roadblock, futher updates as events warrent.

ARRRGGGHH!!! I got my Thinkpad back from being repaired, only to find that they broke more than they fixed. Although the headphone jack now works, the external speakers don't work at all, there's a bunch of wadded up tape in the PCMCIA slot, and the fingerprint scanner doesn't work. These people are a bunch of yo-yo's. As much as i hate to believe it, it seems that Lenovo has already destroyed what IBM had built. I'm very sad to have to say that i would neot recommend that anyone purchase this machine. Drop the extra money and get the T43p, at least that has a system board that isn't 75% faulty. Also note, when they repair your machine they replace the new part with a referbished part, so once everything faulty is replaced you end up with a completely refurbished laptop. If i had wanted one that was refurbished for the price of a new one i would have bought it on e-bay. Buyer beware.

I know this is really beyond the scope of the purpose of the discussion, but i needed to vent.
