Does this have any validity, or is Apple doing a CYA? It kind of makes
sense that an AC adapter might not be able to provide the same kind of
power as a battery that's designed for the full power demanded by the
processor/processes. I'm not an electrical engineer. Please elaborate.
Does this affect PCs? Or is it BS?

MacBook and MacBookPro suffer performance anxiety once the battery is
removed

Are you one of those thrifty-types who's always looking for an angle,
always trying to stretch every last penny? You know who we're talking
about: Montel Williams bases whole episodes around you, the kind of
person who reuses tea bags and separates sheets of triple-ply paper
towels. Unfortunately, it now looks like you now have one less trick at
your disposal. According to Zach Honig over at Gearlog, running your
MacBook or MacBookPro without its battery (trying to squeeze out an
extra month or two of battery life) will cause a significant performance
decrease: we're talking upwards of 40 percent. When he checked Apple's
knowledgebase, it turns out that this is by design -- processor speed is
reduced when the machine detects that its relying solely on A/C to
prevent it from demanding more power than the adapter alone can provide
(and any nasty shutdowns that would result). We don't know if we buy
this line of reasoning, but one thing is certain: if you know what's
good for you, you'll leave that battery where it belongs.
