ACPI\SMO8810 Dell driver [SOLVED!]

Q. Hi, I just bought a Dell laptop and resinstalled Windows 7 on it. Now I have an unknown device ‘ACPI/SMO8810’. What driver can I download to fix it?

A.Here is the download link to solve your ACPI/SMO8810 Unknown Device issue:

NOTE: That is the accelerometer that is built into your laptop.

More details about free fall sensors:

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.

NOTE: The driver is specifically for your Dell laptop’s ST Microelectronics Free Fall Sensor that shows up as Unknown Device ACPI\SMO8810 🙂

The driver installation process:

It is very easy to install and only takes a few clicks once you have downloaded the correct driver  🙂

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. You have a nice laptop!
