Greetings
Have a HP Pavvilion that is having a strange issue.
It runs fine on a full battery, but, when plugged to the wall brick it dosen't charge and it dosen't run on power only if we remove the battery.
Some component is probably dead or has defect and is not letting the current trough.
Problem is I don't have access to the circuit blueprints, and even if I had i'd probably couldn't find the fault without help anyways.
- I tore apart the laptop, hoping to see some visually fried component that could had result from a reverse polarity plug or some current spike, but had no luck with that.
- I used a multimeter to check if the problem with the power could be in the power board, but the power is reaching the pin connector with the 18.40 volts, the same voltage that is measured just outside the wall brick. So I'm guessing that the problem isn't there.
Could you hand me a helping hand in troubleshooting this?
I took a couple of photos from the circuits near the power plug on the mainboard, hoping someone with more experience can help me spot the probable cause of this issue.
