The laptop originally came in with a no power issue. After replacing the battery with a genuine one, it worked fine for 2–3 days, but then started working only on the charger. Shortly after, it stopped powering on completely.
I have tested with another genuine charger and battery – same result. When connecting the charger, the indicator light turns on but goes off after 2–3 seconds. On battery, the laptop sometimes powers on briefly (about 1 minute) until the battery discharges.
During diagnostics, I found unusual readings on PQ200 and PQ1902 – there is a dead short between pins 2–3 and 6–7 on both MOSFETs, but no short to ground.
