I seem to have a missing driver on my new laptop a Dell Studio 1745 If I look under Device Manager, Other Devices is showing an! . Under Other Devices it shows an Unknown Device, this has a downward pointing arrow on it. I tried update but it seemed unable to find a driver for my mysterious device.
The computer seems to work perfectly well so it is a case of “ if it isn’t broke etc....”
Any help or information on this would be much appreciated.
The device is some kind of motion detector.
I didn't have any trouble finding a driver. It was in the list of available drivers for my model when I entered the service tag.
However, you should be able to find the driver by searching Dell's site for:
ST Microelectronics DE351DL Motion Sensor
Hope this helps!!
you need this ST Microelectronics DE351DL Motion Sensor
This is the free fall sensor that prevents the laptop hard drive from losing data if it senses that it is being dropped.
Get Driver from Dell here:
ST Microelectronics Free Fall Sensor
When you're in the device manager, right click on the other devices and left click properties. What do you see under device description?
What is a Dell Service Tag and how do I locate it?

Welcome to Dell Community!
try driver max,it may help to find what the device is&find a driver for it.
Hi guys thanks for trying to help.
If I click on properties of my unknown device I get a General tab with unknown device on it, that is it. If I click on the unknown device and go to properties I get, under Details, Hardware lds. value ACPI/SMO 8800 and then under that *8800.
I think I should mention that the device is disabled at the moment.
Sorry, this is my first Dell and I am still finding my feet with everything, what is driver Max ?
Once again thanks for the help.
I had a similar problem and using windows update helped me fix this. Look in optional updates. For me it was some sort of infrared device. Hope this helps.
@dbdwyer that link doesn't work.
I think I have found the correct link:
Hey guys, this was the driver version that worked for me (and apparently a lot of other people). Hope it helps!
