    Good Day to all,

    Can anyone help me on this unit? No Battery Voltage is read on ther battery terminal,
    If I hang the Battery the battery coil measures 8.5v in the circuit and lights turned Orange
    But if battery is attach it measures 8.5v upon plugging this reduce to 0.230v then the orange light turned white
    Maybe the battery need and en# signal but I cant locate because the unit dont have boardview file
    In the Windows, the battery states that it is 100% Charged

          Can you check the voltage on the battery connector with battery disconnected ?

              ASUS X571 no power : battery issue?
              by mkdj
              Hello everyone,

              Mark and model: ASUS X571
              Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

              Tests already made:
              - Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
              - I have removed...

              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 have tried multiple different Dell power adapters. My Dell...

              Working Asus r752lx, orange light when connect adapter, even without battery
              by baddjavo
              I have 17.3 inch asus laptop probably whit dead battery, so i decided to replace with new one. But not charging, on old battery show 0% and with new battery its 1%. Looks like that laptop detecting battery always. On battery connector its around 15v, 3v, 3v, gnd.
              motherboard is : tmt YA-4A 19 94V-0 E114139, 1533-61-22

              No schematics, no boardview, but i found BQ735 charging chip on mb.U can see voltages on picture.

              I checked mosfets, not all, they looks fine.

              If anyone can explain what here happening ......

              Asus VivoBook F510UA-AH51 won't run on battery after motherboard replacement
              by dhenion
              I'm working on my sister's laptop: Asus VivoBook F510UA-AH51 - The motherboard died so I replaced it.

              The original board was:
              ASUS X510UNR REV 3.0 A

              The replacement board is:
              ASUS X510UNR REV 3.0 B (identical except B vs A - I couldn't find an A board anywhere. Visually they are identical.)

              It boots right up on the replaced motherboard and everything works fine on the new motherboard - but it won't run off battery. When I disconnect the charger it immediately dies. When I plug it back in and reboot the system - it still shows the battery at...

              Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
              by cope
              Hi everyone,

              I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

              Some history:

              Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

              As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

              Now, with a new battery the system will start up and run off...
