Hi to everyone. Laptop brought in windows says: Plugged in not charging. Battery changed by new one, SIO(KBC1126-NU) & Supercharger(BQ24736) changed by new one. BIOS sewed by True and working. Charge MOSFETs changed. any one know where I must Dig? (I found similar schematic and 3rd pin on DCIN(LIMIT_SIGNAL) seems faulty.) |

Power supply checked ? At the central contact no break ? Check interchanged , if possible. |

adaptor changed by new one ---------- Добавлено спустя 2 часа 44 минуты 9 секунд: ---------- https://onedrive.live.com/redir?resid=B ... file%2cpdf There is a similar and good schematic for this platform. 1.I measured Adapter pin(90W) and it was ~ 19V, but when I plugged adapter jack in DCIN1(schematics) 3rd pin(LIMIT_SIGNAL) decrease to 3.4V, is it normal??(I thinks because of D8201. 2.By tracking LIMIT_SIGNAL , Q3802 seems suspicious. Gate=7.7 Source=3.3 but no voltage on Drain, I connect Source to Drain by wire so MB not starts! Wire removed and 3.3V tossed on Drain MB start but everything is same( charge(Amber) LED if off ), and in windows says: Plugged in not charging. |

The normal level of 3dr pin 6.5v. check D8201. |
