Time to Repair Philips Sonicare 9900 Prestige for Loose Screw Rattling

Step by step to disassemble, secure the screw and reassemble the Sonicare:

1. bar clamp (e.g. IRWIN 6") to elegantly squeeze the bottom cap out
2. use a tweezer (HW tools) to loose the attachment and remove the internal body
3. secure the loose screw with a screwdriver (PH 2.5) in the toolbox
4. detach the white cover a bit to expose the power cable connecter
5. reconnect the power cable, see the LED on and make sure the power button works
6. restore the white cover on top of the power cable connector
7. insert the body back and put back the bottom cap in the right orientation
