05/19/21 update.I was quite frustrated with BT keyboard wake up problems; it was taking 20-30 seconds to come alive (on two different keyboards).  I did lots of research and found the standard solutions did not work, although I made all the power setting revisions as suggested.  Mele tech support got involved and sent me a link to the most current drivers; they were very helpful in their communications.  I installed the Qualcomm driver and all was good!  I did read one suggestion that simply said remove all power to the computer including unplugging the power supply.  I did that first and it seemed to work at that point but I went ahead with the driver anyway.I really like this little stick computer.  It’s decently fast and having Win10 Pro is a great feature.  The one problem I’m having is with the keyboard Bluetooth; it just does not work consistently.  The BT mouse is fine but I’ve tried two different BT keyboards without success.  Keyboard function is spotty and very frustrating.  I would not recommend this little gem solely because the keyboard Bluetooth works poorly.
