How are you measuring the 150-300W?
My PC also read 150W+ on a plug-in power meter, but a proper power
reading (using a scope) revealed that the plug-in power meter was
overreading by a factor of 2.

300W is very, very unlikely, unless you have a multiprocessor PC
with terabytes of storage, or you use a projector for your monitor.

Err, yes that may be a bit misleading since it includes the monitor,
Sorry about that.
I measured the voltage across a shunt resistor with a true-RMS Fluke
DMM. I *think* I did the maths properly.
Hmm...maybe I should measure it again.

For the laptop I just measured the DC input current - can't get that
wrong
