Hi all This is a great forum and I have lurked here many times in the past, picking up tips for my HD5 and related stuff. Now I have a reason for posting my own query, I've checked the search function and cannot find anything for this, so apologies if it's a repost... I've had my NW-HD5 for over a year, and in recent weeks it has started to display a "battery is missing" error and then shut off. When restarted it resumes play as normal most of the time. This fault is intermittent, and does not seem to occur for any reason - ie. the player has not been knocked etc. The error suggests that the battery pickups/sensor are registering the fault, but has anyone else had this problem, or know a reason or solution for it? Thanks in advance for any help! Kind regards Bill
