Opinions on these Thinkpads

I'am wanting to know youe thoughts.On these thinkpad notebooks?
1.)T30

2.)A31

3.)T23

4.)R40

 

what specifically do you want to know? They're all about 4 years old, I used the T23 for a while and was happy with it until I used a T40 series notebook. If you can find a good used T23 for under $500 and lots of memory it'd be an okay machine. Same with the T30 I would assume, but never used that model.

 

If you are going to go older, I like the T23. Otherwise I'd take the newer R40.

 

T23. The T30 used P4 cpus, which makes it crap.

 

Agreed.

The T23 uses a Pentium III-M. That's good.

The A31 and T30 use Pentium 4-Ms. Seeing as you own an Inspiron 1150, you've probably seen the bad side of a P4-M.

The R40... Some use P4-Ms, others use Pentium Ms. Go for a P-M one if you're going for the R40.

 

Cool,yeah I hate this 1150

 

T30s had memory slot problems as well.

 

What's bad with a P4-M? It's not like it's a P4-HT. I have a 1.8GHz P4-M in my older laptop. It performs nicely and heats up moderately.

 

They're better than P4-HTs, or regular desktop P4s, yes, but they're still hotter running, and more power consuming than P-Ms. The 1.8GHz P4-M, for example, pulls 30W at full speed. Higher-clocked P4-Ms pull as much as 35W. Compare that to 21W for a 1.8GHz P-M which will downright murder the 1.8 P4-M (or, for that matter, a 2.6GHz P4-M).

Also, a 1.13 P3-M can give a 1.6 P4-M (which a lot of T30s have) one heck of a run for it's money, and it only pulls 21.8W, versus 30W.

I've heard stories of T30s that could easily melt candy bars, and had paint burning off of them.

Besides, sidestepping... who wants something with RAM slot problems?

 

I guess I didn't make my point clear enough. Of course, that the P4-Ms cannot match the current P-Ms, neither in the power saving area, nor in the performance department. And if one is considering which second hand laptop to buy now, of course I'd go for P-M, or even C-M before I go to P4-M. However, in their time, they were good CPUs with adequate performance and no serious issues due to heat or power consumption.

 

In their time, I'd have looked at a P3-M LONG before a P4-M. Besides, if I knew then what I know now, I'd have been all over an X30.

(Yes, I know, my last laptop was a desktop P4 2.2GHz. However, I had no say in that, and I'd have asked for a P-M if I could have. (they had been out for a little while at that point))

 

X30's are pricey aren't they?

 

I'd have been all over an X30 instead of the Dell Inspiron 1100 that they got me - two years ago...
