    Dell N5110 Plugged in, charging but not charging

    My N5110 recently stopped charging the battery, usually people get plugged in not charging issue but my issue is different. I have checked the charger and the battery on other n5110, and its working fine.

    Bios detect the charger wattage but when I go to diagnostic mode by pressing f12 I see the error charger is not detected but it also show the correct wattage of charger.

    The processor cannot achieve full speed, it's always stuck at 0.76 Mhz,
    I figured out a way to solve this problem by using throttlestop software. When I disable BD PROCHOT it starts to work at normal speeds.

    Bluetooth stopped working and I was getting USB not recognized error flashing constantly. So I disabled the USB hub and now I'm on bluetooth dongle.

    What could be the issue, I checked the schematics and it has BQ24745 charging chip but I feel the chip is fine because in windows it says plugged in charging.

    I checked all the other USB ports, HDMI, and VGA, everything else seems to be working just fine.

    Need help!!

        I did flash the bios within windows. I used AFUWINGUI utility to flash and the problem remains.

            Just repaired my n5110 charging issue. Surprisingly it was a water damage around the charging ic BQ24745. Upon close inspection I saw a small white patches on the board which I couldn't see at first.

            CSSP and CSSP (pin 28 and pin 27) line was damaged due to heat and blew off the diode of the board D3902. Got a replacement diode and fixed the PCB lines which got burned with a thin wire.

            Everything seems to be working fine now
