NO he is VERY WRONG !
Average PC now has a 300W or higher PSU, OK that's the MAX it produces, but assume if PC is on at all it'll using a minimum of 100W, so that's 1KW Hour every 10 Hrs, and you are on average home for 90+ Hours per wkk (home = not in office) so that's 9KW Hours wasted.
If you turn it OFF it uses approximately NIL.
Yes when ou turn on a PC it uses more power to spin the hard drives up, but even allowing for that, it's cheaper to turn it off for 5 minutes than leave it on (apart from allowing for the cost of your time waiting for windows to load again)

While it is true that turning your computer on and off every 2 minutes would use more power than keeping it on, this is only true in the context of short periods of time. Turning it off at night certainly uses less power than keeping it on.

No he is wrong.
A computer off uses very little power, the PSU (power supply) alone that is spinning the fan uses way more power than it off.
Even on suspend mode, the computer uses more power than it off...to prove this, suspend a laptop for a few days with only the battery. The battery will be totally dead.
If you leave a laptop off and only battery in...you'll still have battery power.

Of course not. But he may have been referring to wear and tear. Rebooting from a cold shutdown often does put a stain on a computers life span. The act of turning on any switch can cause huge voltage fluxes, granted in the milli secs but just like erosion they add up over time.

Nope it uses the almost the same.
This myth was busted on the show mythbusters on discovery channel.
It proved that there is no measurable electro surge in meter indicators when you turn it on then off or leave it on.
However, they did conclude the processor lifespan over time, is less, when the PC is left on. This is because of the constant heat produced when left on.

He is wrong.
Most computers use 100-300 watts while ON
30 watts on stanby. Just move the mouse and will wake up.
10 on hibernation
3 watts when off.

no, it costs slightly more to leave it in hibernating mode then it does turning it off. it costs alot more to leave it on.
