[PLUG-TALK] Hardware power supplies

   When I bought the ThinkPad X200 it came with no power supply so I did a
web search and saw that replacement supplies were available in both 65W and
90W flavors. Not finding specific requirements for the X200 I bought a 90W
supply. Am I correct in assuming that since the tablet cam run with a 65W
supply that's all it will draw from the 90W unit?

   Another external accessory has the power supply socket labeled for 12v and
I have a wall wart marked 19v. Will this power supply run the accessory's
power supply too hot and shorten its life?

   It's been so long that I did anything with electronic power supplies I've
forgotten all the electrical knowledge I knew way back then.

TIA,

Rich
