Unknown Driver

This question is not answered

I recently bought a Dell Studio 1558 laptop (which I've been very happy with), but updating my drivers today I noticed there was an "Unknown device" in the "Other devices" menu. I formatted my hard drive (leaving the reserved OEM partition) after receiving the laptop and turning it on to check it booted etc. - I didn't want any of the bloat software. I re-installed the OS (Windows 7 x64), all the drivers from the disc and Dell support in the correct order, and updated windows.

The Manufacturer is "Unknown", the Location is "on Microsoft ACPI-Compliant System and there is a Code 2 error (The drivers for this device are not installed. There is no driver selected for the device information set or element.

When updating, it can't find anything, obviously. There is no Driver Provider, Date, Version or Signer.

The Hardware Ids is: ACPI\SMO8800    (next line)     *SMO8800

ConfigFlags: 00000040     (next line)   CONFIGFLAG_FAILEDINSTALL

Object Name: \Device\00000046

 

I'm fairly computer-literate, however I've no idea what this is (something to do with the power?). Any and all help will be greatly appreciated.

Thanks, 

Robin

P.S. There seems to be nothing wrong with my laptop without this driver running, however I hate having things like this on my PC!

  • From what I found when  I had the same problem today is that it has to do with the Accelerometer driver. Found info here: http://www.drivershq.com/Drivers/VistaDevices/Dell-STM-Free-Fall-Sensor-Driver/169003/Drivers.aspx

    While I downloaded the driver and double-clicked on it...it did not actually install. The solution is to go to the /dell/drivers/ accelerometer folder and double click on the Setup icon in there. That will actually install the driver. Restart.

    First of all thanks for this comment. I have this same problem, but when I went to the link you show, it was for 64 bit W7. I have 32 bit W7. Does that matter.

    BUT... in seraching for the driver at the location you suggested in dell/drivers..., I discoved how to finally open and install the driver for my bluetotth 365. After a clean install, the bluetooth module did not even show in in Device manager! You solved that probelm for me accidentally.

    Now.. how to I solve the unknown device problem mentioned in thee iniial post.

    Thanks, Bill

  • You need the ST Micro Free Fall Sensor Driver found here http://support.us.dell.com/support/downloads/download.aspx?c=us&cs=RC1084719&l=en&s=k12&releaseid=R291999&formatcnt=0&libid=0&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=435480

  • Thanks! Worked perfectly for me! Last little thing i couldnt figure out...was driving me mad!

  • Same situation on an E5510, and the "ST Microelectronics Driver" in the "Applications" resolved it.

    Thanks so much!

  • That was the problem. I wish they would have this on the drivers download for the studio. Thanks r0btek!

  • Ah Man this worked Great.....Thanks....

     

  • Yeah, well same exact problem here on a Dell Vostro 3750. That URL which helped everyone here is no longer available.

    Will look around some more and while feeling Dell doesnt care anylonger.

    And I have a Vostro 3750 resource CD and still unable to install the driver for this.

     

     

  • Same issue on my E5420 Dell, and even worse, the link mentioned in previous posts is now not valid anymore, it has been removed. I am not pleased with this at all :(.

    • For systems with Dell Bluetooth 355, 360, 365, 370, 375 and 380. Use the Bluetooth 380 Driver here: http://ftp1.dell.com/folder00865420m/1/

  • This thread is amazing and saved me from additional stress. The ST Microelectronics driver can be found under the System Utilities section. Big Smile

  • Glad it helped. :)

  • Thanks for the tip, worked for an E6410. I already had the ST Micro Free Fall Sensor Driver, but chose not to install it, didn't seem important, and then I forgot about it :)

    Anyway, crazy things happen with Dell Laptops... never thought it's this complicate to install a system... on my Sony Vaio all drivers are already installed from the first boot of a new Windows installation!

  • I'm facing same problem...
