M4800 Won't turn on

My m4800 worked for a day. Now when I push the power button, the screen doesn't turn on but the power button glows. Then a few moments later, the fan whirs very loudly and then the power button light shuts off. There are still random lights like the battery and wifi lights on either way.

What are some things you would try?

The MB must have failed. Return the laptop for a replacement or call support. You can also try re-seating the RAM if possible and resetting out the CMOS.

Please post in the M4800 owner's thread for faster responses.
