Hi,

When the laptop uses Wireless, the fan spins more. I suppose the laptop needs more power to make the wireless adaptor work. Is the power consumption affected by the following factors:

- Encryption: does WPA2 consume more?

- Complexity of password: would a 64 characters long password require more power than a 10 chars pwd?

- Distance from Wireless router: would weaker signal strength need more processing from the laptop?

Thanks for any advice.
