Select Language:

If you’re seeing a yellow triangle with an exclamation point next to the “Simple PCI Communications Controller” on your HP Pavilion b&o 550-163ns running Windows 10, it means there’s a problem with that device’s driver. The device, identified by PCI\VEN_8086&DEV_A13A, needs an additional driver to work properly.

Here’s how you can resolve this issue:

First, try updating the driver through Windows Device Manager. To do this, right-click on the Start menu and select “Device Manager.” Look for the “Other devices” section and find the “PCI Simple Communications Controller” or a similar item with a warning icon. Right-click on it and choose “Update driver.” Then select “Search automatically for updated driver software.” Windows will attempt to find and install the correct driver.

If Windows can’t find the driver automatically, you’ll need to visit your computer or motherboard manufacturer’s website. For HP devices, go to HP’s official support page and enter your model number—Pavilion b&o 550-163ns—and look for the chipset or communications controller driver. Download and install the latest version available.

After installing the driver, restart your computer. The warning icon should disappear, and your device should function correctly.

If you still see the warning, it may help to uninstall the device from Device Manager. Right-click on the device and select “Uninstall device.” Then restart your computer and let Windows try to reinstall the driver automatically or follow the previous steps to manually install the driver.

In summary, ensure you update or reinstall the driver for the PCI Simple Communications Controller through Windows Update or your device manufacturer’s website. This should resolve the yellow warning triangle and restore proper device functionality.
