Thanks for that.

When I had the initial problems with the camera switching off I did a little research and came across other s5i owners who had experienced the same sort of problem. The common denominator appears to be exposure of the camera to extreme heat or cold afterwhich the problem seems to occur - camera is switched on, beeps a few times and then switches off. After several (frustrating) attempts to switch it on, it eventually would and then work well (apart from the fact that it would only recognise th einternal memory even when an SD card was inserted. Even that could be overcome with a little patience - reminds me coaxing my first car to start in the morning ! Users point to an internal battery - 5mm by 1mm (although they could only find one slightly larger) which when replaced and the camera is reset returns the camera to full working condition.

Had my s5i for 3/4 years now - been a good camera - fond of it. Started switching itself off last year and not recognising the SD Card. Kind of got by by being patient with it. Last month the charger did not register the camera - no lights appear when in the charging stand. Checked the fuse and connections. A forum suggested that there was an internal battery that needs replacing (but it wasn't cheap or easy). Realise that it might be the end of the road - but just wondered if anyone had any ideas ?
