Whoops, I forgot to remove the email out of your post. Silly me.
Thanks for doing it for me.
If the laptop is under a year old, I would use the warranty now.
Anything you do to the laptop now to try and fix it may void the warranty.
Basically take the laptop and all the papers that came with it to the store.
Explain the problem (maybe show them as well) and ask them to fix it.
If you want to keep whatever is on the hard drive (all your data and/or personal files), tell them to help you back them up.
With the warranty, they should get it fixed for free.
