T40 vs T41 vs T42 ??

[kstuart]

Hello,

Well, from various comments on the subject of T23 vs T40, I'm getting the impression that IBM made a number of improvements in the T4x line aside from the usual cpu speed, and memory speed.

So, I'm now looking at getting a T4x - although that is stretching my budget somewhat.

While scanning ebay auctions, as well as stores' used T4x offerings, I'm finding that while there is an overall and general increase of price with increase in model number , in many instances that is not true, and I've seen some T41's and T42's sell for less than some T40's.

I've also seen T41's and T42's offered with the same speed of CPU, same amount of memory, same HD and same screen size and resolution as many T40's.

SO, is there anything implicit in the T41 and T42 models that are improved over the T40 - aside from CPU speed and memory speed - frankly, I will probably be running at 600mhz to conserve battery life more often than I will be coming close to taxing even at 1.3 Ghz CPU.

The only one I am aware of is the HD Protection (and opinions of whether that is worth spending more $$ are welcom).

Thanks!

If im not wrong i think you got like four open topics for the same thing.

The other ones all involved T23 vs T40.

For "historical" reasons, there was one on screens, one on wireless, and one overall differences.

( If PhPBB ever allowed searching on "topic subjects only" then one could easily find all the previous discussions about it. )

The T40 model configurations top out at 100Mbps wired Ethernet capability, while all the later T4x models support 1Gbps wired Ethernet.

Cheers,

Thanks.

It's good for products to keep up with new standards, but outside of corporation/university environment (which admittedly includes a lot on this Forum, but not myself), I can't see that havnig a practical impact.

But it's interesting to hear about.

Not true ... my T40 (2373-72U) came new with 1GB ethernet.

I believe the motherboards are more reliable in the later series than in the T40. This is based on what I have read over the months on this forum. If anyone feels this is in error, please pipe up.

Generally speaking, the WiFi cards are more up-to-date in the T42's, and include G. But you would want to double-check this on any model that you purchase.

Battery MaxiMiser has more features on the T42 than in the previous models.

The older models use HPA or PARTIES for the service partition. The newer models use WinPE, which is easier to deal with. Of course some people do not care about the service partition.

I believe I read that the Recovery CD's could be made by the user from the T42 onward. The user can only make one set unless he restores factory contents. Likely you will not be able to make a set yourself unless the original user never made a set, or unless he restored factory contents before selling it. You could have the seller check for you if this option is still available. If the service partition is still intact on a T42, you may be able to restore factory contents and then make a set yourself.

EDIT: One additional note. If Rescue and Recovery has been updated from the original version that came with the ThinkPad, and you restore factory contents, you might not be able to boot into Rescue and Recovery again. You need to check the README for Rescue and Recovery to see if you can fix this.

T40: Banias processor, PC2100 memory
T41: Banias processor, PC2700 memory
T42: Dothan processor, PC2700 memory
T43: Dothan processor, PC2-4200 memory

They all are good. Spec's were close on all. Some T40's have larger drives, faster cpu's, more features (BlueTooth, big batteries, high res. LCD), and longer warranties than even T41's or T42's. The only thing that certain is that the highest end of each model does trump the prior models.

So, a T40p with 60GB 7200rpm drive, 1GB of RAM, BlueTooth, 1.6 cpu, high res. LCD, 3 year warranty with some remaining will probably sell for more than a T42 with 30GB 4200rpm drive, 256MB of RAM, no BT, 1.5 cpu, standard LCD, and nothing left of 1 year warranty.

Some T42's didn't even have a Dothan processor! Take a look at these models - 2373-1UU, 2373-1YU, 2373-1WU - they have basic T40 specs. w/Banias CPU's.

Make sense?

One major speed increase was the GPU. While all three series were available with the standard Radeon 7500, the T40 topped out with a Radeon 9000, the T42 and T42p topped out with the T41p offering Radeon 9600 and FireGl T2. The 7500 performs about a third of what the 9600/T2 does in 3d apps and don't offer DX8 features.
