Unknown Device - on PCI Bus - ACPI\SMO8800 / ~SMO8800 - IRQ 0x00000017 (23)

Thank you for your help.

Dynamite! This worked for me... had the same issue...   Thanks!

Thanks. I have a Vostro 3500 and it worked for me too :emotion-1:

Thanks for that

It worked on my DELL XPS15, L502X

I had searched everywhere for it!

Pity it isn't included in the  L502X Downloads pages, it would have saved a lot of time!!

I am very grateful for your help

Thanks for the info, worked on XPS 17, L702X. 

Great, thanks for posting back to let us know it worked.

I have the same problem but does this solution apply to a Dell Studio 1745 as well!? I didn't know that it had a "free fall sensor" as well....

Yes the ST Microelectronics free fall sensor is common among many models.http://ftp.dell.com/FOLDER01168946M/1/Chipset_Driver_XWJWG_WN_4.10.0036_A05.EXE

Thanks from another very grateful Dell user, this is exactly what I've been looking for to stop my "missing driver" messages. Cheers!

Thank you very much!

I am adding another thanks to you for the solution provided. After reading your message, before downloading and installing the driver, I went to the Dell page and look at all the drivers for my laptop (I also have a Dell XPS 15 L502X) and no matter how I looked for it, I could not find it. It is a shame that Dell does not provide a driver for a component they know they placed on the laptop as part of its configuration.

I don't know how did you find out about this driver but it has been of great help for many of us, thank you very much!

Thank you very much! :-)

It also works fine with Vostro V13 on Win 10 Pro, thanks a lot
