I have 1,5 y old Prague . Now I have power problem. I have to push "M" 10-30 times until power is on. And sometimes I loose power also in biking. No error codes are shown.Battery is OK. How to test where is the problem. NCM dealer in Finland is very poor but I like my Prague.
 
Loose connection seems like a possibility, you'd had a look and no chance there's a bare wire, corroded wire or bad connector around where the battery connects?
 
If you make a habit of removing the battery all the time, a lot of dirt/debris/oil can get smushed into the male/female contacts.

The contacts on the battery were so dirty, I had to open the battery, so I could safely clean it with solvents/soap/water.
