Unibody Macbook Pro battery cover?

[whitefang]

If I take out the battery and use AC power, is there a battery cover for the battery slot in the laptop?

Why would you do that? It's going to run slower...unless you already know that

Wait what? It's going to run slower on AC power than battery power??

Didn't you know that? If you remove the battery and just run on AC power the processor speed reduces by about 50%.

It gets asked so often here im not going to explain why but you can search to find out more.

What? That makes no sense. I know that Intel processors has SpeedStep which reduces the clock when the processor isn't been used, this happens regardless of power source. However, automatically reducing the clock because the battery is removed, that doesn't make sense.

EDIT: Ah ok, the magsafe connector only provides 85 watts so if the macbook needs more power, it has to draw from the battery. If there is no battery, it has to reduce it's clock.
