er, hibernate IS powering down. S3 powers off everything (Disks, CPU, |
16 |
fans) but leaves a minimal amount of power to the solid-state |
17 |
no-moveable-parts RAM. S4 writes a bunch of stuff to disks and then |
18 |
powers down just like a normal shut down (S5). You can even take out |
19 |
the battery (I even stripped an old laptop, removed the cpu, disks, heat |
20 |
pipes, fans, and put it all back together on S4 and then resumed). S4 |
21 |
can leave some bios function and power for WOL and other devices, but |
22 |
it's not essential. |

In fact S5 which every modern ATX computer does STILL leaves power to |
25 |
USB, WOL, modems & keyboards, if required. |

So when I say 12 day uptimes, this is calculated by the kernel since I |
28 |
last rebooted, not since I last hibernated. I'm not actually running |
29 |
the laptop for 12 days continuously. Although, IMHO, there's no |
30 |
difference to a laptop or desktop in this regard. |

Push it to the limits I say ;) |
