This driver provides support for the accelerometer found in various HP laptops

"HP 3D DriveGuard". It detect automatically laptops with this sensor. Known models

(for now the HP 2133, nc6420, nc2510, nc8510, nc84x0, nw9440 and nx9420) will

calibrate - read: values (x, y, z) that are used as the base for input class device operation.

If your laptop model is not recognized (cf "dmesg"), you can send an email to the

authors to add it to the database.  When reporting a new laptop, please include

the output of "dmidecode" plus the value of /sys/devices/platform/lis3lv02d/position
