    MacBook Air A2179 blanck display on both Internal or External display

    Hi, I have this MacBook Air A2179 that doesn't display image on both internal or External display screens. It turns on normally and boots normally. Pressing the Capslock shows it is functioning normally. The backlight comes on too. Adjusting the screen backlight can be noticed by the way the screen brightens or dims.

    At first, i thought it was a faulty lcd BUT it still doesn't display on an external monitor when connected via HDMI.

    Nothing else has been done so far besides examining the motherboard for corrosion which wasn't found.

    I need help on this. Thanks

      Put your computer into DFU mode and do a Revive Device.

        Macbook Air 2020 A2179 Internet Recovery and Battery Issues
        by cheebster
        Hello, i have a batch of 10 Macbook Pros A2179 bought from a Costco return wholesaler.


        The 10 of them show the exact same behavior;

        They auto power on, to internet recovery spinning globe, fans to 100%.

        Power consumption on USB-C port is 0.43a, shuts down as soon as unplugged. Battery doesn't charge at all. However, it boots to 20V on the Ampmeter.

        Based on their iBridge versions (4.x and 5.x) these were shelfed for a long time.

        All of them power on the same way; 100% fans, shut down as soon as they are unplugged. Removing...

        Macbook Pro A1989 - No image, working fine with external monitor
        by Madoy104
        Hi everyone,


        I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know...

        MacBook A1990 vertical stripes on external screen
        by ahoonid
        Hey everyone,

        I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

        The board is neat. Not opened before for sure. Just a little dust, nothing more.

        Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...

        A2179 Macbook Air turns ON and works normally with a battery but it is not charging
        by CAPTGENE
        I have similar a similar issue. My A2179 Macbook Air turns ON and works normally with a battery but it is not charging. With the USC-C alone it takes 20V but only 100mA, PPBUS is 12.3Volts, and wont turn ON.

        I replaced U7000 twice with the same result. not charging!

        Whats should I check or replace?

        MacBook Pro 2018 with Activation Lock
        by envym
        Hi everyone!

        I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

        I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...
