ACPI\SMO8800 Dell [SOLVED]
Q. Hello, I have a Dell laptop and I just reinstalled Windows 7 Ultimate x64 on it. Now I have an unknown device ‘ACPI\SMO8800′ in device manager. What driver can I download to fix it?
A. Here is the download link for the driver that should solve your ACPI\SMO8800 Unknown Device issue:
local mirror, Dell dl link
NOTE: The driver is for your Dell laptop’s ST Microelectronics Free Fall Sensor, it is what shows up as Unknown Device ACPI\SMO8800
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.
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!
