Modem Device on High Definition Audio Bus drivers missing

Posted on 2010-09-23
Last Modified: 2013-12-01
Does anyone know where I can locate the "Modem Device on High Definition Audio Bus" drivers for a Lenovo W510? Lenovo system update doesn't support Win XP 64-bit, none of the driver packages I manually downloaded from their web site had it and hotfix KB835221 didn't work either.

Thank you

Please go to your device manager. Right click your device in question, select "Properties" from the drop down menu. Then navigate to the "Details" tab. In the drop-down combo box, select "Hardware IDs" or "Compatible IDs" and please tell me the information that is returned. I will then give you link to proper driver. The Device ID should be formatted as VEN_XXX&DEV_XXX where XXX are numbers or letters.

Didn't update drivers for the devices mentioned above. That is the installation package I used originally and the audio on the laptop works correctly

Device manager still lists

I think I can help you. First you need to update your BIOS. Please choose the correct method to use (If their windows-based flash utility wont run on 64bit OS they offer a bootable ISO image to flash your bios. One of the updates is to the Embedded Controller which is actually one of your unknown devices (probably a reason for an update?)  This *should* and i hope i am right, be the driver you need its a pretty generic (but hard to find because it should have been in your windows installation) Install this FIRST. That should cover both of those unknown devices. Then use the audio and modem drivers provided on the first link I gave you above on the Lenovo site. If that does not work you need to reload your OS, you may have registry errors. Also check Start->Programs->Accessories->System Tools->System Information check your hardware environment for any device conflicts. If the first step does not work. Also you could try resetting your BIOS back to default settings (should be F2 at boot I am not sure for IBM). Hope that helped.

It can be because of the order you installed the drivers in.
it sounds stupid, but it can ;)

Do you miss any functionality or is this because it alarms you?
