Does a notebook computer use power when shut off?

[kspeed55]

Toshiba says it does and that is why my Portege battery loses charge when in the computer is not used for a few days but stays fully charged when I remove the batter for the same length of time. For instance, the battery was completely dead (computer wouldn’t turn on) when not used for 9 days but after 3 1/2 days with the battery out of the computer, it showed 99% after booting. Both times the battery had a full charge at the beginning.

Hello,

I feel your pain. My Dell XPS 18 loses 7% of charge every 24 hours, i.e., it is dead in 14 days. It is completely, fully, properly SHUT DOWN. No power to USB ports. No wake on LAN. Nothing! And Dell says "it is normal," which I believe is balderdash.

PS. The battery is brand new. Old battery (before replaced under warranty) drained 9% in 24 hours.

I believe all those instances of power drain are not normal. Because what is shut down is shut down. The term itself implies that nothing consumes power.
