    mbp i brought since dec 09 has been doing some wierd beeping sound recently most notably when i just tilt the laptop a bit sidewards.

    it has also frozen twice and with the beeping sound on constant in 3-5 sec bursts.

    the origin on the beep i think is on the bottom right of the mbp which i assume is the hdd?!

    any help would be appreciated thanks

    Sounds like the sudden motion sensor. Did you change the drive? If not there is a firmware update you may be able to do. You can also disable the sensor on your mac.

    I swapped my 320 gig for a 500 and mine beeps from time to time. I cant do the firmware update, when I tried to run it my laptop said I don't need to. I was going to try and disable the sensor on my mac to see if it works (my drive has its own sensor) but I have been to busy.....

    open terminal and type
    sudo pmset -a sms 0
    this will disable the Sudden Motion Sensor.

    what about the random freeze with the constant beep which only leads me into doing a hard restart for it to work again. is it something to do wiv my hdd? its happened twice already
