Re: sasmsung problem charging

Change Or check Power adapter ,(using bench power supply Instead of adapter )
Download Schematic And check Charger IC And Components (Mosfets , Caps , Fuse ,...)
Check Voltage On Charger IC

Re: sasmsung problem charging

Re: sasmsung problem charging

it's easy to change one mosfet, but it's difficult to change charging ic, my answer was based on my proper experience, because i have repaired two laptop with the same problem (platform scal 2 and scala 3)
