I was having the same “try try again”… and then give up with a red error message. The failure always occurred on a carpet (my only practical plug-in location) until I used 1/4in white masonite (pressboard) with beveled edges. I then used 10lb/4.5Kg double stick foam tape to adhere the charger base to the board. Problem solved!
“Problem Solved” NOT !!!
I really thought I had fixed the constant back up and retry charger docking problem ! Twas not to be. Soon after my last posting “BB” (Big Bot) went back to his old “Where’s The Power?” ways !
Very frustrating for BOTH of us.
After a few inspiring sessions in my morning “Think Tank” (nice hot shower)
I decided that what Big Bot needed was a “shower” of his own. Perhaps something just needed to be washed off?
What if the electrical contact strips still had a thin film of something left over from the manufacturing process? Perhaps a little buffing wax (those chromium strips sure did SHINE when I first took BB out of his box)… perhaps a thin layer of oil… or even some kind of poly material?
Bottom line… after applying a little fine grain sandpaper to all contacts my little buddy BB has not failed a 1st time charger docking in the last dozen trials !!!
Problem REALLY solved… at last !
