Palmrests are designed to raise your palms, reduce muscle activity and to keep your wrists in a neutral (straight) position. One of the major factors determining the selection of Palm rests is the type of your system, as it needs to be compatible with its design and structure. It is also important to note accessories included with the product as some of the Palmrests come with Touchpad, CMOS battery, Speakers, Touch Pad/Track Stick Button, LEDs, antennas. We recommend that you use the System Drill Down or the Service Tag look up functionality to buy the correct Palmrest for your system.
