The slider switch on mine has failed too. It jams in one or two 'up' positions that make no difference. Mine is the Braun 7505, but essentially the same as many others. YouTube has one video on the topic, solving the problem with a hammer. Unhelpful. :-/ Anyone tackled the sliding switch problem? Certainly not a battery issue. Thx.

This is good advice from Jimmy C - we have a starter how-to here, the crucial part being the initial removal of the clip at the base, but there's more detail on YouTube especially with regard to detaching the batteries from their solder.

WHAT WOULD BE REALLY VALUABLE is info on the impenetrable SLIDER SWITCH that can lose its blue button and metal retainer spring. I'm on the verge of writing off my shaver that's in good working condition but won't turn off by breaking the switch apart to see how it works.

The battery slips out towards you. Lift gently as in the photo and pull it horizontally. It reveals a number of metal prongs that normally reside inside the battery.

As with most components, treat the prongs carefully. Gently align them with the receptacle in the new battery and they should slip in easily.

This step can be omitted if you can prop the keyboard up and get access to the disk screws with a screwdriver, not entirely easy.

It’s probably best to release the ribbon cables. Flip up the narrow grey clamps, up beyond the vertical, and slip the cables out.

To put them back in, keep the clamp strips up, then push the flat cables in. They go in 4 or 5 mm. Then rotate the clamp strips back down. Give a gentle tug on the cables to make sure they’re firmly held.
