New Macbooks performance suffers with only AC Power

Posted by: Michael on Nov 24, 2008

Gearlog reported this weekend that while they were testing a Macbook Pro they found that the machines performance took a nose dive while it was running on only AC power, with the battery completely removed.

TUAW did a little research and found a Support Document that claims this is done to prevent “the computer from shutting down if it demands more power than the A/C adapter alone can provide.”

Gearlog is reporting a 36% lower processor benchmark with the battery removed. Obviously its not hard to prevent this…just keep the battery in…but it’s interesting to note.

What a ridiculous explanation! The AC is supposed to be able to supply enough power to both run the computer and charge the battery at the same time.
