yeah, i read about changes from 16V to 20V.

not necessary, since my dc-dc-converter lets me set the desired output
voltage (from 15V up to 24V). my main problem is that i have troubles
finding the correct plug. i only found it as part of the thinkpad power
supply and i don't want to buy another psu just for the plug. it seems,
that this design is only used by lenovo products, which is a bit
annoying. i understand the idea of making the new plug deliberately not
fitting anymore to older thinkpads (in order to not fry them), but was
it necessary to use something completely new?

for my part, i'll get some standardized neutrik (or whatsoever) female
and male plugs and insert them into the cable, so that i can easily
switch between the original thinkpad psu and the dc-dc-converter. 

thanks for all the answers
