ACPI SMO8800 driver missing for Dell E6410/E6420/E6510/E6520 – unknown device ACPI SMO8800 65

We received a bunch of new Dell E6420’s at work, and needed to get them prepped for drivers and our image deployment. We run a deployment process through Landesk OSD, with HII (Hardware Independent Imaging), which basically means that we have 1 image for multiple model computers.

I installed our basic Windows 7 Pro x32 image on the new machine, and was going through drivers that needed to be installed, and ran into one tricky one. In Device Manager, right-click the device and click Properties. Under the details tab, choose Hardware ID from the drop box. You’ll see something like ACPI\SMO8800 (that’s what the unknown device was on mine). Google that hardware ID and you’ll find that it’s an accelerometer, a device that detects when your laptop may be falling and instantly stops the hard disk so it isn’t damaged on impact.

I went through and extracted the drivers for it in Windows 7 x86/x64, Vista x86/x64, and XP x86/x64. The zip file is 2.79 MB (2,926,227 bytes). You can download the drivers here : LINK IS DEAD

All you have to do is extract it (I use 7zip), and navigate your update drivers to your respective OS version and x86/x64 version. If you want a more detailed write up on how to do it, with pictures, let me know.

Hopefully this helps :).

    If someone needs the driver for ACPI\SMO8800 just search for “ST Microelectronics Free Fall Sensor Driver”.
