New MacBooks Take Big Performance Hit With Battery Removed
Wired: Gadget Lab —
Apple's new MacBooks are mighty speedy, but they suffer from a huge performance drop if you remove the battery and use the AC adapter as the sole source of power.
Gearlog's Zach Honig discovered that the MacBook sees a 37-percent drop in speed when running without a battery.
Honig benchmarked a 2.53 GHz MacBook Pro using a multiprocessor test called Cinebench R10. With the battery present, the MacBook Pro turned in a score of 5,549. Without the battery, it scored 3,504.
While this may appear to be a minor issue -- since most ...

They contacted Apple to find out what's going on, and Apple admitted that the performance difference is intentional, explaining that it "prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide." Sounds a little fishy to me, but it doesn't really matter: Apple took a lot of care with that battery, and if you know what's good for you, you'll leave it be. [Gearlog] ...
