I noticed that my new production N900 has a problem starting to charge when plugging in the charger, too. I tried it several times and sometimes it started charging, sometimes it didn't.

Then I tried the charger from my preproduction N900 and it doesn't make any problems at all. The N900 always immediately started to charge after plugging it in.

Hmm, I'm gonna try if the production charger causes the problems with the preproduction N900, too. Then it would definitely be the charger to blame.


EDIT: Now both chargers seem to work on both devices. Maybe the charger just had to get capacitors fully loaded for functioning reliably first?
