    Samsung R60 charging problem

    When I connect charger without battery it power green light, when I put battery it also turns red light, but after 1 second it starts to turn on and off red light. On dc power I can see how its current is going over 4a and falls to 0a every second.

    I replaced every fet on line, replaced max1909 charging chip, and still the same. I think max1909 cliks in tact with current upping and falling, probably turns on and off.

    please someone help

      Check for shorted ceramic capacitors on all of the major power rails. Note: CPU/GPU/NB power rails may appear shorted due to their low internal resistance so checking those is not always possible.

              HP Probook 470 G4 - Power and Charging Problem
              by Scoff
              Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
              Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

              by roman728
              Hello guys,

              I have a problem with charging circuit in this laptop. Unit came with no power at all (USB-C meter was cycling turning off and on). I discovered that when I unplug battery laptop works on charger only. So after few measurements I found shorted 1st dual mosfet AONY36324. Unfortunately i was not able to order exact this one, so i ordered AONY36352 which i believe is the similar one. Now the problem is, when i connect battery and charger USB-C meter is not cycling anymore, it starts charging (reading 20V@2,7A) but after few seconds it is going down to 20V@0,20A and laptop...
