missing driver for mysterious device?

This question is answered

Hi all

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.

Many thanks

Perky

  • 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.

  • Perky,

     

    When you're in the device manager, right click on the other devices and left click properties. What do you see under device description?

  • 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.
