On the Dell Precision M6800/OXD1M5, BIOS A26 06/13/2029, Linux prints the warning below. i801_smbus 0000:00:1f.4: Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration Following the same suggestions by Wolfram Sang as for the Dell Precision 3540 [1], the accelerometer can be successfully found on I2C bus 0 at address 0x29. $ echo lis3lv02d 0x29 | sudo tee /sys/bus/i2c/devices/i2c-0/new_device lis3lv02d 0x29 $ dmesg | tail -5 [1185.385204] lis3lv02d_i2c 0-0029: supply Vdd not found, using dummy regulator [1185.385235] lis3lv02d_i2c 0-0029: supply Vdd_IO not found, using dummy regulator [1185.399689] lis3lv02d: 8 bits 3DC sensor found [1185.449391] input: ST LIS3LV02DL Accelerometer as /devices/platform/lis3lv02d/input/input371 [1185.449577] i2c i2c-0: new_device: Instantiated device lis3lv02d at 0x29 So, the device has that accelerometer. Add the I2C address to the mapping list, and test it successfully on the device.
