Neodymium magnet slammed onto Laptop?

Hi, I have this 1inch cube Neodymium magnet that has a pull force of about 100lbs. I only have one of them so I assume that the pull force will be much weaker on other objects.
Now when my mom was using the laptop she placed the laptop under the bed as usual( to allow for more space for an additional mattress). Without knowing I had my magnet down there, there was a loud bang on the laptop and then it suddenly blacks out. My mom isn’t kind of alert so she just left it and stowed it down there.
The next morning when I woke up, found the magnet stuck under the laptop, about slightly left from the center of it. Immediately I realized something must have happened and when I turned it on, it boots perfectly but now has a loud humming/buzzing sound when in operation. Is there a way to fix it?

IN SUMMARY: My Neodymium magnet slammed onto the laptop from under, the lap still boots fine but has a humming/buzzing sound when turned on. I still have yet to check for any functionality issues. I understand that powerful magnets can screw hard drives. How can I fix the noise? Thanks!
The CD drive is empty.
I would appreciate if anyone can tell me a few ways to check for any damages to the laptop.
*Bah, screw the magnet, I knew something bad would happen :/ *
-The laptop now shuts down without warning with a soft cluck(same sound when I hold the power button to force shut down)
-The laptop fails to start up, blacks out after showing ‘windows failed to start’/

-The laptop is only about 6 months old, Vaio
