    Re: HP EliteBook 840 G5 charging issue

    Found cap short
    Replaced
    PVSYS now is 19.8V and previous problem components don’t overheat
    But as suspected there are more issues
    Charger in shows 19.8V and power led goes white
    Attempt to start gives constant flashing white CAPS LCK and NUM LCK
    Searching deeper into schematic

        To finalize
        Traced issue to smart charging/power/battery chip
        Rabbit hole is too deep
        Going to vendor

                See the diagram in post #3 here:

                https://www.badcaps.net/forum/troubl...ing-components

                At the top left is a parts legend. Those parts are compatible if the suggested parts are changed during the pcb assembly.

                        ASUS X54H laptop thinks it's always charging even with charger unplugged
                        by flat-earther
                        The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

                        Windows also shows ''Plugged in'' when charger is not connected.

                        This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
                        Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
                        If I let battery run out and say it has 3% Windows will...

                        HP probook 4510s mosfet issue
                        by Cuboy
                        Hello,

                        I am currently trying to help a ONG by volunteering to help repair laptops, it's something that i have been into since 2017, always watching videos, on discords, forums etc...

                        I have an HP ProBook 4510s laptop that does not power on and has no indicator lights, which suggests an issue with the power supply or the motherboard.

                        I started by verifying that there is voltage at the input of the motherboard, confirming that the power adapter is working correctly. However, when I checked the voltage at the output of the first MOSFET (Q1032), I found 19V at...

                        MacBook Air M1 A2337 battery/charging issue
                        by drlarsen
                        Hello. Sorry for the long post, but I am trying to decide if this is a simple battery replacement, or potentially something more complicated.

                        I bought an open box MacBook Air M1 2020 A2337. Seller claimed it was never used. Visually, it appears pristine.

                        On arrival, the battery was completely flat. Computer powers up and boots fine. Battery status showing 1% and charging, 1 cycle. coconutBattery showing 0 mAh and ~6 watts.
                        After some hours, the battery status did not improve. Restore via DFU did not help.

                        I connected the power adapter to a Kill-a-Watt...

                        MacBook Air A1466 820-00165 Charging Issue
                        by DominikPechac
                        Hello everyone,

                        I have a problem identifying a problem on this MacBook Air A1466 with board 820-00165.
                        A customer came in with a problem, the laptop was not charging. Otherwise, it works fine - runs from a battery without an issue. The battery is original, the customer also provided his original charger.

                        However, when I was diagnosing the issue, I turned the laptop off, checked the board, etc. When I put everything back together, the laptop was charging (I inserted the charger and then turned the laptop on). After unplugging the charger and plugging it back,...
