Asking because I have recently installed two 19'' screens on boats. One was TFT the other was LCD. One used 1.5A the other 0.5A.
I have also found that some USB HDs will nor run off one port - they need more energy than one USB port provides. And it provides a lot.
Screens and HDs are indeed major juice consumers, also video cards. All this talk of processors is only half the story. The smaller the screen
the less energy. I don't have any numbers at hand, and not going to be anal and go testing every component, but I know I have the lowest power drive in my "big" (12" screen) laptop, its a WD Scorpio Blue 320gb
. I get the 320gb because its the largest capacity you can get with only a single
platter. It's extremely efficient. On my netbook i use an SSD drive, can't get any more energy efficient than that these days...
I use the same 320gb scorpio blue for my USB backup drives and it only needs a single
USB connection. Even to play movies directly off it or run massive transfers, like full system backups...
High end graphics processors will cost quite a bit of energy. My thinkpad uses the standard GMA950 controller, and the netbook uses the 945GME, both are shared memory solid state processors and extremely energy efficient when compared to the bigger nVidia and ATA processors. Both can handle HD playback with plenty power to spare.
There's no question the newer computers are more energy efficient than older ones, but they still don't have to cost $1000+
Also note that thinkpads are standard built with spill resistant keyboards
and hard drive 'drop' protection (even most of the older ones). Plus the built in drop protection on the hard
drive mentioned above. Its a non-issue with the SSD in the netbook.
Another plus for the thinkpad is that they all look alike
you can't tell if its a $2000 computer or a $300 one, which is a big plus if you're going to be taking into cafe's in questionable regions.
