The Pentium shaver doesn't charge in and the lights don't turn on. This is the first charge
If you can use a multimeter, can be used to measure the resistance profile, can also use the method of voltage, voltage measurement must be the charger plugged into the socket, the above method is the judgment of the charger is damaged.
The indicator light is not on, indicating no power to enter, I think your charger is broken, and carefully check whether the electrical equipment has hidden broken line, check the charger's head and tail
If there is no problem with measuring the charger, then the shaver is inside and you have to return or repair it to the dealer. My answer hopes to help you
