    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

                          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                          by Bowline
                          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.

                          I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

                          Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

                          The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...

                          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
                          by serious_electron
                          Hello Everyone!

                          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.                          ...
