Question:
The Windows ACPI driver, Acpi.sys, is an inbox component of the Windows operating system. The responsibilities of Acpi.sys include support for power management and Plug and Play (PnP) device enumeration. On hardware platforms that have an ACPI BIOS, the HAL causes Acpi.sys to be loaded during system startup at the base of the device tree. Re: acpismo88001 Jump to solution Sorry for resurrecting this old thread but for anyone experiencing this issue the device in question is most likely an 'STMicroelectronics 3-Axis Digital Accelerometer' also known as a 'Free Fall Sensor'.

More details:
That free-fall sensor is an accelerometer which can detect movement (i.e. downward acceleration or falling) and using that sensor your laptop can take steps to protect itself by parking the hard drive heads or other measure.
IBM pioneered this technology in their ThinkPad line way back in 2003 and Dell has implemented it as well. Of course, it has applications beyond protection as even the Apple iPad/iPad 2/iPhones have an accelerometer which developers can use for games and other purposes!
PS I would like to thank you for your question, as I am a bit fan of the Latitude E series (and also the Dell Precision line). You have a nice laptop!
