SOURCE: braun 7526 shaver switch
Managed to fix it - actually was a 7680. Only do this if you:
1. have a small screwdriver set
2. are handy putting little delicate plastic pieces and springs together again
3. are prepared to face the possibility that you might break the shaver entirely
4. you are out of warranty so you don't care if you invalidate it
THE PROBLEM is caused by a small flat metal assembly that acts as a spring to hold the blue button in place. That is held by 4 small glue posts. The glue breaks down, the flat spring falls out of place and the blue button is no long in the right place.
TO OPEN UP THE SHAVER
a. gently remove the plastic cover around the electrical socket underneath, using a small flathead screwdriver to pry it open
b. the two metallic sides of the shaver can be pulled away starting at the bottom of the shaver
c. uncrew the four screws on the underside of the shaver
d. remove cutter block, battery/lcd block (make sure you don't lose the grommet around the lcd display
e. pull the spring and little plastic latch off the underside of the switch, make sure you remember how to put it back (took me almost 20 mins to figure out how to get that back afterwards)
f. slide the switch all the way up and pull it off the slide - you might need a little gentle force and a flathead screwdriver to coax it off - be careful you don't break anything here
g. remove the trimmer from the rest of the switch
h. put the blue piece back in place (mine had fallen out), then glue the flat metal spring back in place. I smeared brush-on crazy glue on the flat surfaces to hold it in place, I would imagine a four drops of reasonably strong glue on each of the glue posts would work best. Wait for the glue to dry and achieve strength.
i. slide the trimmer back into place, then the plastic latch and spring - this is the tricky part. Make sure the switch can slide on/off in all positions properly.
j. put the display/battery & cutter block back in place. put the back of the shaver on, hold the shaver together with your fingers and test the switch works in all positions without jamming. If so put the four screws back, followed by the metallic sides followed by the plastic cover of the electrical socket.

Your batteries are starting to degrade, but the good news is they're still holding a charge for a week, so you really don't need to rush to replace them at this point.
The flickering of the charged indicator is normal, as the shaver is still plugged in and the batteries are fully charged. The flickering is due to the batteries chemicals breaking down, and as such, the charge cycle keeps "topping" them off while it's still plugged in.
When you finally aren't able to get a decent amount of cordless operation and run times from your shaver, then you'll want to get them replaced, whether you decide to do that yourself or have it done by a professional service center, is up to you.
Here's a reference for your future use. www.electricshaver.com carries replacement (factory OEM) batteries for most brands of shavers and they also will provide the repair/replacement service for you, should you decide you don't want to do it yourself. You can also give them a call at 1-888-476-1785 and request a price quote, etc.
Anyway, your shaver is working fine and all you need to do is make sure you're not letting the shaver stay plugged in and charging constantly for more than a day, since any "extra" chargind isn't doing anything except keeping the batteries at a constant state of charge. Heat is a byproduct of charging and discharging any battery and as such, you want to allow for a cool down period before recharging them.
I tend to use my shaver until it is almost completely discharged before recharging it. By doing this, you can get the longest working life out of your batteries before you'll have to replace them.
Hope you find this Very Helpful and best regards!

It my be the batteries but they usually go bad very gradually and you should still be able to use it from the cord. It sounds more like a problem with the circuit board.
I suggest that you first find out if it can be covered under warranty. You can call an authorized service center at 847-869-7755. They can tell by the date code on it when it was made. If it was made less than 2 years ago. you shouldn't need your receipt.

If working properly, model 5510 will work either from the internal rechargeable batteries or directly from the cord. If your shaver no longer recharges, it needs to have the rechargeable batteries replaced.
