I just acquired a rather nice secondhand PB All-In-One. It has a TV tuner, and comes with a remote. But: I can't get the remote to function. An IR driver is loaded and shows no errors, so the only thing I'm left to think is that the remote's batteries are dead. It uses a pair of those flat silver ones, about the size of a 10p piece. I checked with the seller, and she had never used the remote in the two years she'd had the PC. So: have the batteries just died - even though they've never been used - and I need to replace them?

To check if a remote is working point it at a digital camera or video camera, and observe it on the camera screen. You should see it flashing when you press a button as the camera sensor will detect the Infra Red.
A few years ago, I took apart an old video camera battery unit, as it was not powering up the camera. I managed to salvage 9 out of 10 batteries (1.2V rechargeable), which were connected 'in series' inside the unit, only 1 'dead cell' was causing the malfuntion. I re-used the working batteries in other devices.
