>The major exceptions to this are notebooks – MacBook Pro, MacBook Air, and MacBook – as their internal batteries provide their own backup power. As a result, if you do connect one of those to a UPS, it won’t be compatible with its USB connection that would otherwise be used to trigger shutdown when the mains supply is lost. Notebooks still benefit greatly from the filtered mains supply from a UPS, though.
This doesn't sound right, is this the case? Wont a Mac laptop be powered through a UPS backup power?
[edit] Ah, I think he just means the Mac laptop wont be getting the special over-USB signal a UPS can send that tells it "please shutdown, as the power wont last much longer".
That's OK though, since if I have my laptop on UPS, I'm either there using it (so I can do that myself, if mains power is lost and before the UPS runs out) or it's configured to sleep after some inactivity anyway.
