Lenovo Thinkpad t430s - what Ac to get ? 65W AC Adapter or 90 ?

There are two options from a drop down menu.

One is lighter that the other?
One may charge the laptop quicker but both give the screen the same brightness?

The 65W may work under most circumstances, but it may not be powerful enough under all circumstances: e.g. if you're running CPU/GPU intensive work while watching a DVD and charging the battery, all at the same time.

90W is intended if you are using a port replicator with external monitors, etc.  65W is intended for traveling user who needs it to just charge the battery and not using any external monitors, etc.

The only practical difference is, as you've already noted, the 95w unit can charge the battery quicker.    Otherwise, everything else works exactly the same.    If weight's an issue, I'd get the 65w unit;  if not get the 95w.

I have a ThinkPad X230 that came with a 65-watt adapter. It is the same as a T430 except it has no DVD device on board and has a slightly smaller screen. All this is well within the scope of a 65-watt supply.

It works great and charge the battery from 1 hour remaining to full charge in about an hour, maybe a bit more. So that is from about 20% charge to full in about an hour or a bit more (while the machine is running).

The 65-watt adapter runs very cool. So I would definitely recommend it.
