Question about Braun 4501 Electric Shaver
How do I disassemble the braun 150 shaver to replace the circuit board and battery?
Thanks for your attention and help.
1) Use a small flat screw driver pry off the bottom (where the cord plugs in)
2) Remove the silver sides
3) Using a small torq driver remove the 4 scews
4) Open shaver
5) Remove circuit board with batteries
6) Install new circuit board and reassemble

If the "reset" described didn't work all that well, as a last resort you can replace the batteries. You have two choices: put in a battery/circuit-board part replacement (drop in), or solder in new batteries. If you've got some soldering experience, I recommend replacing just the batteries. You can buy new NiMH AA 1.2v flat top batteries rather cheaply (less than $4 per cell) and using a soldering iron, take out the old ones and secure the new ones. Look for batteries with at least a 1650mAh rating. Good luck!

You will need to first remove the 'cap' on the bottom of the shaver. This is a piece of plastic that surround the hole on the bottom of the shaver where the cord plugs in. Gently pry it off with a small flat screwdriver or similar object. Once removed, the side grips will simply pull off revealing 4 screws on the back. Remove screws to remove the back cover.
From there it is a piece of cake. The internal components simply lift out.
Put it back together in reverse order

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.
