“Apple bluetooth keyboard won't pair - why? Everytime I try to pair my Apple keyboard, which works fine with my Apple laptop, I get the following message: Adding this device to this computer failed. Adding the device failed resulting in an unknown error. The reported error code is: 0x80004005. My Apple mouse paired with no issues. The computer is an Acer netbook, Aspire One D270-1998. Software loaded via usb cd drive. Any suggestions, besides returning the adapter and trying a different one?”
