OK so it's hardly 'mechanics', but we don't have an electronics section here do we?! I was just wondering if any owners of (especially Specialized) bike computers had experienced Sudden Death of their unit after changing a battery! Mine is over 8 years old and started displaying odd measurements yesterday morning after my ride into work. I changed the battery at lunch time and it appears to have snuffed it. I put the old battery back in case the new one was duff, but to no avail. Have I forgotten something, like a reset switch or is it curtains for this particular box of tricks?
