    Apple Macbooks use what they call Sudden Motion Sensor and Lenovo Laptops use what they call Active Protection Service.What theses services are suppose to do is to protect from shock or sudden vibration or even rapid movement.

    Basically a sensor inside is suppose to trigger when the above conditions occur and put a break on a parking break so to speak. This disengages the drive disk heads from the hard disk platter preventing data lose and drive damage from disk head crash.

    I don't see this service mentioned in most other laptops and wonder what value it actual serves,unless you drop your laptop often or live in a area prone to earth quakes.

    In some cases the service needs to be disabled for example a music recording studio subject to vibrations or perhaps a night club.So in this case what stops data lose or disk damage.

    FYI. Active hard-drive protection (See Implementation).

    My HP laptop came with ProtectSmart Hard Drive Protection and it's one of the reasons why I bought it.

    Thanks JR for the link.Good to know.

    One article i read if the information Is accurate or not but was said that If a laptop with this service was dropped,this service would kick in before the laptop even touches the ground.If thats true,thats pretty cool.

    Dark Shadow,

    Many other laptop manufacturers have similar technology, off the top of my head:

    HP use "HP 3D Driveguard".
    Toshiba laptops use "HDD Protection".

    I bet a google search shows up more.

    I have APS on my Thinkpad.
    Sensitivity can be turned down and can be turned on/off from the UI.

    Its use is for people who pick their laptops up and move around rooms (meetings, which I do every day) or travelling to protect the HDD heads crashing mainly.

    Cheers, Nick
