    Hello anyone can guide me to this issue, macbook a1297 5 white blinks, then starts ok, gpu still alive,
    .. laptop works fine but no amber not charging but bat is detected in mac os high sierra, and says 68% but removing magsafe cable it turns off instantly
    It is a 2010 macbook pro a1297 820 2849...

    Is this a sensor issue? Or a bat issue? Thanks a lot!! cpu is performing quite slow...

    Pd of course original 85w charger, fans runs normal not 100%, and did test ASD (diagnostics ASD OS 3S138) for this macbook , and was all ok i think.

      Sounds like a bad battery. How many charge cycles on the battery? Test with a known good battery.

      See here for more details:

        Macbook Pro M1 (A2338) - Not Charging but Detected and Post
        by bibinskii
        A client showed up with a Macbook Pro M1 stating that the battery doesn't get charged (no increase in percentage) but still charge. She left me with the battery 25% and still draining. The Macbook is fully functional. I checked with coconut battery and system report. Battery health shows 85% and stating normal condition, no abnormalities. When it is charging, the system says it takes 10 hour to finish charging. I went ahead to charge it for a longer period, the battery just drains (doesn't get charged).

        At first, I thought that this must be a battery issue. I went to replace the battery....

        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...

        MacBook Pro 2018 - A1990 Dead - not charging - only 5V
        by robka
        Hi,

        my MacBook Pro 15" 2018 Touch Bar (A1990) doesn't charge anymore. Board# 820-01041-A

        I'm not experienced in diagnostics, but I want to try to solve the problem with your help, because every local shop charges around 600โ‚ฌ (650 usd). Which is the value of the whole Macbook.

        The Macbook was charging when suddenly the "charging sound" appeared every other second for around 4-5 times.
        After that the Macbook was dead. It isn't charging anymore.

        The USB-C Port where the charger was plugged is burned. Also The Cable and the...

        MacBook Pro A2289 no signs of life except clicking trackpad and charging
        by Woodsworth
        Hi,

        I hope this is the correct place to post about this device. I originally posted regarding this on iFixit so see the details from that post below:

        "I'm hoping someone can give their opinion on the symptoms I'm seeing before I spend any more time and put money into this. I got this MacBook from a customer and after looking at it they decided they didn't want it.

        It doesn't turn on and there's no visual signs of life. I have tried resetting the NVRAM, SMC, power cycling, unplugging the battery, using the charger with the battery unplugged. Removed the...
