Hi:

The missing driver is not for the Bluetooth.

It is the AmdAS4 service that is missing the driver.   What that is, I do not know.

What I do know is I have zipped up and attached below, the driver you need for that device.

Download and unzip the file to its folder.   Do not do anything with the files in the folder.

Go to the device manager, click on the unknown device needing the driver.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option and browse to the driver folder you unzipped.

Make sure the Include Subfolders box is checked, and the driver will install.

Then restart the PC.

hello and thanks for fast response. had this problem awhile now but only device manager seems to have a problem ie; yellow warning icon and "needs maintenance" note. windows security and maintenance claims devices and drives ok no actions needed. I thought it was my Bluetooth because I uninstalled/disabled it when win10 was new Bluetooth auto loaded on start and interfered with my wifi working at all. windows did fix/patch the problem and I didn't reinstall as I didn't use Bluetooth at the time. about 6 mons ago I installed Quallcom suite and driver installer but cant find device or settings for Bluetooth even with suite installed. My wifi device is Qualcom so I assumed my Bluetooth was too. probably why unknown device driver not available. maybe Bluetooth is realtech like my audio driver is. thanks for this fix. ill apply later today and maybe learn what AmdAS4 service is. will post results later tonite and thanks again Paul!

You're very welcome.

According to the product specs for your model notebook, it does not come with built in Bluetooth networking capability, or that feature would have been listed along with the 1x1 802.11b/g/n WLAN wireless connectivity specification.

The parts list for your notebook indicates that it comes with an Atheros AR9485 802.11b/g/n 1x1 WiFi adapter.

That model wifi adapter is not a combination wifi/Bluetooth adapter, which is why you can't find any Bluetooth devices or settings.

thanks for that info. somehow I never was sure about BT being on my notebook as my user manual is "if on your model" about features. uninstall BT SUITE and get USB BT Device. Unzip and install w/folders. let you know soon.

[Paul_Tikkanen]

Anytime.

Glad to have been of assistance.

I use this Bluetooth adapter, and W10 installs the driver automatically after a couple of minutes online.

excellent fix when I found the files in file explorer. the Browse for driver window was difficult to navigate but a piece of cake after extraction. Graphics in my games seem smoother in play. Maybe my AMD E-6010 R2 graphics processer will benefit from this AMD system driver. uninstalled BT driver and found old Nero programs and MacAfee stuff that was hiding out. Hard to find all software parts to uninstall all programs. thanks for the fix. this HP community site is easy compared to Microsoft community site. i'll use this site soon.

You're very welcome.

If the graphics is working better/smoother, that device must be part of the graphics subsystem.
