Does this gadget stop the fan on your computer when it is in standby mode ?

Q: What kind of sleep mode does ecobutton™ actually engage, is it just the normal Standby mode?
A: No, ecobutton™ does not employ the normal Standby mode (although you may get the on screen message 'Preparing to Standby' when you use your ecobutton™). The mode that ecobutton™ engages is a deeper energy saving mode than the regular Standby mode you usually find as default on a Windows PC.
On most PCs there are 4 inbuilt sleep states - S1, S2, S3 and S4. With each successive sleep state, from S1 to S4 (hibernate), more of the computer is shut down. However, the majority of PCs are actually supplied with S2 and S3 disabled leaving just the most shallow sleep state (S1) and the deepest (S4 hibernate) available to most users. Most people tend not to use hibernate due to the length of time the PC takes to wake up leaving just S1 as the only convenient option.
The sleep states built into most PCs are as follows:
S1 = Basic Standby (Shallow sleep). Typically wakes up in no more than two seconds
S2 = Less power consumption than S1 and greater than in S3. Wake up is usually two seconds or slightly more.
S3 = Less power consumption than in S2. Wake up time is the same as S2.
S4 (hibernate) = The lowest power state but with a long wake up time - sometimes a few minutes or more.
ecobutton™ re-educates your PC to use S3 when the ecobutton™ is pressed. - confused? In essence the answer is yes, but it depends on a number of variables
