Base System Device driver in WIndows 7

I recently installed WIndows 7 on my Lenovo 3000 G430 system, and all the drivers except for a few got installed automatically during the installation process...


But then I noticed in Device Manager, I have 2 devices that are listed under 'Other Devices' that don't have a driver installed. I tried a direct search for drivers online, but it couldnt find any.

Both of them are by the title 'Base System Device'.


I checked the Lenovo wesite for drivers, but there are no drivers listed for WIndows 7. A few guys had raised this issue in the forum previously too, but they were not using Windows7, and I did not have this issue when I was using Vista...


Please help...

Re: Base System Device driver in WIndows 7

On my N100, "base system device" was related to card reader

and/or modem.


Either try the card reader driver for vista for your model,

or one from THIS page if you have a Ricoh reader.


If the drivers do not help, but everything works fine,

just ignore it I guess.

I had the same problem with my N500 laptop after installing Windows 7.

I had to install the drivers for JMicron flash media controler.

Go here:


JMB38X MS Host Controller and JMB38X SD/MMC Host  Controller drivers.

Hello tusharkaul,
Have you checked compatibility?
Just an FYI for you.

It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibilty.)
There is a pulldown from which you can choose "hardware" and "software".

There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site:

In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!

As stated previously, it's best to have the Windows 7 certified drivers installed.

Microsoft does have an official Windows 7 Support Forum located here . It is supported by product specialists as well as engineers and support teams. You may want to check the threads available there for additional assitance and support.

Thanks again,
John M.

Re: Lenovo G430 Windows 7

@ rovirg

re-install power management for windows 7, too

it contains system files that function keys need to work properly.

Hi tusharkaul,


Try below to identify what components they are.

Check the Device ID to find our its description:

  1. Right click the unknown device and choose Properties.
  2. Go to 'Details' tab.
  3. Choose 'Hardware ids' from the Property drop down list

  4.  Take the IDs and google them and find out the descriptions of the devices. You should know what you are missing.
