(used) T420 QuadCore FrankenPad ~ To Buy or Not To Buy ???

#1 Post by Annecy » Sat Apr 07, 2018 2:17 am

I've come across a used/2nd-Hand T420 QuadCore FrankenPad for sale ...
I've read some TPF T420 QuadCore ForumThreads; e.g.,
SOLD: T420 i7-3610QM ...
SOLD: $40 -- T420 MB 63Y1989 w/ Coreboot -- accepts Ivy Bridge CPU

I'd like to ask/know ...
How would/should I proceed to assess making the purchase ???

Seemingly (imo) ...
the T420, T520 & W520 were the final "classic" ThinkPads ... (nicht wahr :?:)
before Lenovo changed/ruined the TP KeyBoard:

TeamLiquid: Lenovo and the Thinkpad keyboard change

Last month I "tried out" ... for the first time ever ...
a "PostClassic" TP ~ X230 ...
I still can't fathom ... why ...
the PrtSc key was/is so "prominently" placed ???
& ...
When did the AppsKey start disappearing ... from keyboards ?!?!?! :shock:
I (also) couldn't believe :-o
when I asked the X230 owner,
"Where's the AppsKey ???
the reply was, "The what ??? :eek: :roll:

no

buying t420 over t430 is an idiotic decision no matter who recommends you that

with some effort, the t430 can have 7-row keyboard just like the T420, but have the advantage of usb3/better chassis/better chipset.

it will accept 2133mhz memory (g.skill cl11) with factory bios


I recommend you visit the /r/thinkpad discord in my signature, there are much more people with the knowledge willing to help you (one in particular is very experienced with the T430).

That's not a quad-core, but a dual-core i7 with Hyper-Threading enabled, which exposes a "virtual core" for every physical CPU core. A quad-core i7 would show up as 8 cores in Device Manager.

Laptop Core i7 models with Q in the model number are quad-cores, like i7-3612QM.
Daily driver: X220 4291-C91 i7-2620M

Backup: X220 4291-P79 i5-2520M
Toy: X60F Core Solo U1300
In pieces: two retired but working X61Ts
RIP: 760XD 9546-U9E; X61 7676-A24; and a BOE-Hydis HV121P01-100 in failed SXGA+ mod

Thanks for the link!
Modified T470 to look like TP Anniversary Edition; TP 25; E550; T540p; wants a T420 or P1 to see what's good.
