Mac made wierd sound, slower now

[-mattias-]

Just got home after having rode on my bicycle with my Mac in a bag. Last time I used it, it was drained for battery, but when I got home and plugged the power in and turned it on, it said this weird sound. So I turned it off. Even after it was turned off, it made the sound. Then I unplugged the power and the sound lasted another 5 seconds before it stopped. Then I turned my Mac back on, the sound was gone, but now it seems run a bit slower.

I don't know if my Mac has gotten any knocks when it was in my bag.

Took this video of the sound just when I had unplugged the power:

Anyone know what this can be? Thanks!

Sounds like the optical drive misbehaving a bit. Got a disc in there?
I honestly doubt it could have any impact on the performance of your machine post-restart.

Thanks for the answer!
But no, I don't.
I think it could be the trackpad not responding all the time actually. Is there any way to test, if it's not working 100%?

That sounds very much like the optical drive "spinning up" and then "spinning back down".

Are you -sure- there's no disc in it?

I'm sure there's no disc in it. Have tried the eject button and have checked with Disk Utility.

After having used it for 2 days now, I've noticed the following:
The trackpad doesn't always respond when I click on it, though if I tap, it works all the time.
The bootup time have increased significantly.

It takes my Mac about 30 seconds from the startup sound to the Apple logo appearing and then an additional extra time for the loading bar to complete. Is that normal?

Also just took the extended Apple Hardware Test. It said there was no problems...
