X220s?

#1 Post by Thinkpad4by3 » Sat Sep 16, 2017 9:05 am

Why was there no X220s or 'proper' X230s? Did they ever exist?

No, AFAIK. The closest thing to an X220s is the regular X220 chassis with a ULV processor and the single heatpipe heatsink (04W0436) that weighs only 34 grams IIRC.
Daily driver: X220 4291-P79 i5-2520M

In reserve: X61 T7500, X60 T2300
In pieces: X60s CS U1300 [board only], two retired but working X61Ts
RIP: 760XD 9546-U9E

As to "why": my guess is that the battery life was the biggest thing. The second Core generation (Sandy Bridge) that X220 is based on brought much improved power efficiency, which allowed the mainstream full-voltage CPUs to achieve comparable battery life to low-voltage CPUs of previous generations. Thus it was deemed unnecessary to have a whole parallel product just for the ULV CPU, although as axur-delmeria pointed out: customized-to-order X220 units with ULV CPUs and a lighter heatsink were, in fact, made.

I knew about that, but isnt truly a xx30 series. In my mind, that is an X240, as is the T430u a T440.
