typical Microsoft nightmare . first the instruction for pair the keyboard to the computer do not clearly state you have to type the passkey number \*\* on the keyboard \*\*\* & PRESS ENTER to PAIR the keyboard with the computer . I spend hour try to get the keyboard to work . what throw I off be the first time I set it up , I do not have to type the passkey on the keyboard . the keyboard and computer drop the connection and when I try to re-install it would not pair with the computer . bring it back to Staples for a replacement . -lrb- too bad I do not find out until too late that my keyboard be function - it be the documentation which do not work . -rrb- get a new keyboard , get it to sync once , then it drop the connection and I could not get the keyboard to broadcast - keep push the bluetooth button to make the keyboard discoverable , but only get a green light and no flash red . then no green light at all . Staples be go to be sick of I try to return the new keyboard for the old one , but this be a disaster . look for a HP or Logitech bluetooth keyboard .
