@Philips_Support_N @IvoGrijt i need some help here. I received my ppm yesterday. I put it on the original charger and i turn it on. The blue red light was flashing. 5 minutes later the ppm run out of battery and shut down.i tryed to turn it on again but it wasnt open. i thought it was the battery so I leave it closed and charge it. At the beginning the red light was solid but i notice that around 15 minutes later it started the blue red light. I disconnect the charger and i try it again. After 15 minutes it startet again rhe same issue. I changed the charger with my macbook which has the same voltage and the same thing happened again. I never manage to turn the ppm again. Any ideas?
