Getting a T43, a few questions

#1 Post by Intergalactic Captain » Mon Mar 25, 2013 9:16 am

Been a while since I've posted here, but long story short the past couple years have sucked... Finally at the point where I'm able to replace my failing POS T40 and try and get back into the fix and sell game. So after getting all my ebay and paypal stuff straightened out, I'm the soon to be new owner of a T43, T42, and R40 - Complete systems, No OS, T42 is the only one with HDD - but it's bios locked... Grand total $90, I figure I can work with that...

I plan on swapping the HDD from the 42 to the 43 and using the latter as my new machine. Is there anything I need to worry about here with the bios lock? Not sure what level it is, or if it even matters, but IDE drives are worth their weight in gold now and if it works it's essentially a free laptop for the cost of the drive.

Second, have there been any developments in the last few years in regards to maxing out T4x cpu power? My T43's coming in at 1.83 Dothan, how far can I go with that platform? I'm assuming dual-core isn't happening.

Third, how reliable is the SATA mod? The last time I was active here it wall still all speculation - Now it seems to be a possibility. I'm confident that I could perform it, but I'm concerned with stability - I've got an SATA ultrabay sled for my t40, but having the ultrabay free for optical drives is preferable. On the same hand, what's the largest HDD that would be recognized? A 500gig SATA is going to be about the same price as a 40gig IDE, and for dollars of difference I'd rather go big...

Finally, I'm looking for a feeling on going prices. Last time I paid attention, T4x's with NO issues in stock configuration with OS were selling at $150-250... Now, cursory ebay looks more like $80-150. Is this a good ballpark to work with? I know T4x's are freaking old and about to be left in the dust with this whole tablet game, but I need to get back into business and they're the last thing I've really worked with - The R40's a fluke, ten dollar HDD and I double my investment on return...

...Thanks for any suggestions, been a while but I'll probably be active here again in short order...

Max. CPU in a T43/T43p/R52 is a 2.26GHz Pentium M 780 (SL7VB).
It runs rather hot, the 1.86 it comes with is much more civil.
Intel and ATI graphics require a different fan.
Swapping HD from T42 to T43 is no problem, but you will need to freshly install your OS.
I have done probably 50 SATA mods on T43 machines by now, all of them are still running, some of them as long as nearly 2 years.
There's a new BIOS out for T43 made by TTAV134, which eliminates Error 2010 (HD) and 1802 (wifi).
Max. IDE laptop drive is 320GB
Max. SATA laptop drive is currently at 1TB, maybe even more.
I've also put an UXGA screen with LED backlight in a T43: http://forum.thinkpads.com/viewtopic.php?f=2&t=107018
Check the Marketforum (and eBay) for prices.

Short and sweet - Thank you... HDD swaps are a piece of cake, what I was worried about is the fact that the 42 is bios locked - As I said, it's not in my hands yet... I've cleared SVP's before, but only on stripped machines - I want the HDD out of this one, and I'm curious as to whether being bios-locked will complicate its usability - Never dealt with this so I'm not sure if it's an issue or not...

If only the BIOS is locked, then there's no problem.
If the HD also has a password, you have a doorstopper.

I can vouch for the SATA Mod!!! It is AWESOME. My daughters T43p with the mod from RBS is a totally new machine now. Fast fast fast!

You can always take the locked HDD apart, and hang the platter from your rear-view. :mrgreen:

OP:
The ThinkPad will display a symbol when it starts up. If it shows a padlock, then it is a system board PW. If it looks like a cylinder, then it is a HDD PW. Either one can be a user or supervisor PW. It COULD have BOTH types.

Waiting for the fedex guy always sucks... T43 should be here today, have the r40 up and running (main machine ATM)... T42 ships tomorrow...

Still researching the SATA mod, looks like I've got the intel GPU which will complicate it a bit - Already have everything I need from past projects so the hardware at least is taken care of - Have a 60gig drive for testing and looking at a couple of 500gig drives when its up and running.

...So my next question regards the 400->533fsb pinmod, which I haven't found much information on here. From what I have found, anything with a 915 chipset (all t43's) can take it... I've got a 1.5 banias from my last t40 which I plan on testing for proof of concept, if it works it'll run just shy of 2GHz... Question is, why has everyone stopped w/ 1.7 (735)? Sure, the fastest 533 was the 2.26 780, and a T43 will take it, but what about a 1.8 745 running at 2.39, or a 755 at 2.66? Stability issues aside, will a T43 run over 2.26 at all? 735, 745, and 755 are all under $20 right now, so if it's simply the matter that it hasn't been tried I'd be willing to give it a shot.

Well the cooling would also be a problem. The 780 and the 765 are both incredibly hot cpu's. There was a reason they didn't clock the PM series higher. Just go with the 765/755 for the 400 fbs boards and 780/770 for the 533 boards. Not worth the effort IMHO.
