And searching “removing beo5 battery” on google brings up some suggestions for difficult to remove batteries.
Once you start programming DO NOT rely on the USB connection to your PC to charge, it is not strong enough. Especially with the Beo6 because if you drain the battery and the remote goes dead, it is very difficult to revive. I always leave the dock plugged into the mains, and only plug into my PC for putting the file on to the remote to test, then connect back to the mains.
