[SOLVED] Red light flashes next to barrel-port

OP updated

Hi Ron,

Thank you for the insightful information. Have you managed to make any progress?
Our symptoms sound similar since my PBP also completely stopped charging from the barrel-port - however I managed to solve all my symptoms by using a USB-C power supply (updated OP). For some reason the power supply that came with the PBP and or barrel-port appeared to be damaged/faulty for me. Have you tried charging using the USB-C port?

Kind regards,
Carl

As above Carl, still stuggling with this one. Yes I've tried the USB-C port but also gives me the red blinking LED.

I'm gald to hear it was just a faulty power supply that was causing your issue, I hope your PBP serves you well on battery power.

Cheers,
Ron

I have seen this when I first got the pbp in the fall.  In my case,  I had taken out the battery and had  the connectors reversed when I reinstalled it.  Assuming that you didn't do that,  is it possible that  one of the connectors is damaged,  or that the battery did have the connectors reversed?   IF that were the case, though,  you still should be able to boot with the battery out and the bypass connected.

I've ruled out the battery as the cause, all the connections are fine and it's charging on an external charger without issue. The thermistor resistance is also within the expected range. The machine boots with the bypass cables inplace, but without the bypass I get the red flashing led.

I'm leaning toward the charging IC being damaged.

Thanks for your response,
Ron
