Smaller AC adapter

Had look at the latest T60 and X60 on the pc stores here.
and observed the ac adapter is smaller with the output of 3.5A instead of 4.5A as my T43.

does that mean, that T60 has less power consumption and thus less heat

any idea?

It might be a 3.5A, but I read that it is now a 20V instead of 16V.

but the adapter looks much more smaller than the old T4x series.

3.5A at 20V = ~70W. Since the new AC adapter that ships with the T60 is a 90W and is larger than the standard T4x adapter, you must have been looking at this adapter.

Is anyone here using the 65W adapter?

I am thinking of buying one, for two reasons:
1) it's smaller
2) I don't need it to "fast charge" as it will be plugged in most of the time.

Is 2) the only benefit of the 90W adapter?

It is possible to overheat the adapter and undervolt the laptop except, (and only except) if the laptop is turned off. These questions keep coming up.

The ONLY practical recommendation on adapaters is to use ONLY the adapter specified by IBM. It is not worth having a problem or a failure.

EDIT: Figured it out. It is only compatible with the 945GM models. By this I think it means "Integrated Graphics".

I have tried the 65W Adapter and it works just fine. That 65W adapter comes with the lower-end T60's like the 1951-C2U

I have plugged that adapter into my T60p 2623-D8U (top of the line with 256MB Video & 7200RPM HD) and it seems to work just fine. The adapter did not get very hot either and I had it on and using the machine for 2 hours or so.

Tommorow I will order another 65W for travel
