Já liguei duas vezes no suporte da Apple. Na primeira vez me sugeriram a limpeza do teclado, mas não funcionou. Da segunda vez, fizemos os 2 seguintes passos: Como usar o modo de segurança no Mac e Usar o Diagnóstico Apple para testar o Mac.

Mas não resolveu.

Alguém já viu esse tipo de problema?

a alguns dias o meu computador parou de ligar e ao que tudo indica o problema é a bateria, já que o sistema já estava pedindo pra trocar.

eu estava buscando o modelo correto para trocar a bateria, mas pro meu computador eu só consigo achar baterias pro macbook air late 2010 A1370 7,3V.

Porém, o meu computador é 14,5V, queria saber se ele é compatível e se seria um problema comprar coma voltagem diferente.

obrigada.

estou com um problema no meu macbook air, é como se não existisse wifi nele, não há na rede a opção de wifi, já fiz todos testes de reset disso e aquilo, tentei reiniciar segurando “D” para fazer teste de hardware mas aparece “contact support -1005d”, algo do tipo.

Eu acredito que o problema é na placa wifi, mas embora fique triste em dizer isso ouvi dizer que pode ser a própria placa mãe, alguém especializado pode me ajudar, por favor?

O meu sofreu uma pequena queda e ficou amassado em uma das 4 laterais. O display não foi prejudicado, apenas uma das "quinas" entortou.

ele chegou aqui e teve uma hora que ligou depois de uma semana ele volto com mesmo problema de não ligar, agora ele de vez em quando ele liga mais não da imagem so fica a luz verde do carregador e tem horas que nem liga e nem aparece a luz na fonte dele

English: MacBook does not turn on

The mec already in assistance, already tested all the components and everything seems normal is passing right energy stream.

He came here and had an hour called after a week he'll be back with the same problem of not connecting, he now occasionally he calls more not the only image is green charger light and has hours that do not care and neither appears the light in his source.

I didn't get the display with the machine since it was toast—the T-CON board was still mounted in the top case and all the cables were totally ripped, hinges were still screwed in as well, just none of the rest of the display

Surprisingly, the thing still boots. I didn't even have to do anything. I can get into it no problem. Have recovered data for said friend.

But since said friend doesn't want it back, I wanted to get some use out of it. I need to get some pictures for the MacBook Data Recovery Guide I've been working on for Share Disk Mode steps and this is the only Apple Silicon Mac I have access to.

It will not show the startup options screen on the external display I have connected. It may be on the correct menu, but I would have no way of knowing since it doesn't output the primary display, only the secondary display in an extended setup. All I get is a black screen and mouse pointer if I manage to get the pointer on the second screen. Oddly, the internal display is still "detected" when I'm in OS. Maybe that's normal? But I don't even have the eDP cable connected.

Powering on never gets me an Apple logo even if it's booting, and I never see whatever was supposed to be on the primary display until it gets to OS where I have it set to mirrored mode.

I have tried various terminal commands I've found, which all errored as invalid (they all reference NVRAM which is handled differently on Apple Silicon Macs). I tried triggering lid closed signals via magnets. I've tried clicking blindly, and pressing keys in some combination that might make sense for selecting the Options button. But no change.

Please help me so I can help you.

UPDATE 03/19/2023: I have messed with this a whole bunch more, just for the sake of science, but still to no avail. I have seen others who mention this sort of behavior on Apple Silicon Macs. The internal display is still detected even when it is not present.

So I went into science mode. I powered it up and measured IPD_LID_OPEN_1V8. Which measured almost 1.8V on the nose. Neither of the hall sensors containing components are even connected.

Electrically speaking, I'm willing to bet it still thinks this display is detected. And it's open. But I'm not sure where the initial detect signal or logic comes from. So. I thought. I wonder what happens if I just break the line for the aforementioned Lid Open signal. So I removed RR203. This broke the path for this 1.8V signal to be transmitted elsewhere.

Now when I connected power to the board, it thinks the lid is closed, so it won't auto power on. I can probably force a shut signal by shorting that line after I'm sure the machine is on. I can get it to power on by shorting pads, but it acts weirder than it was before.

I will probably see what happens if you break some of the enable lines, or power rails for the display.

There may be an issue with the fan ppf003

There may be an issue with the camera ndc001

The fan is running flat out, using Mac fan control app I can see the computer is reading the RPM correctly as it fluctuates up and down in RPM slightly and all temperature sensors appear to be working. Using photo booth I can confirm the camera is working perfectly too.

I have done nvram and pram reset but still same two errors. I read online that if the camera is not seated correctly it will cause the fan to run flat out so I double checked the connector for it and it's in nice and snug. I've removed it and reinserted it 3 times, same error but still camera works perfectly in MacOS.

How can I tell the Mac the camera is working fine and to dismiss this error?

On the slight chance I have somehow damaged the fan I have ordered another one although it seems to be fine from everything I can see. I have tried to reseat the fan cable multiple times too.

I have issues with my 2020 macbook air.

It think that it is always closed. I can't get it out of sleep for more than 2 seconds (if plugged in) and keyboard and trackpad don't work.

It works great with external monitor and peripherals.

I tried : new keyboard/trackpad flex cable, new trackpad, unpluggin the screen, le left speaker and microphone array (i saw that the lid sensorS are on the mics / right speaker), tried unplugging every board i could, nothing change.

What can i test now ? Maybe the soundcard board ? Can the lid sensor management be bad ?

I'm a bit lost.

Thank you very much !

Hello @danj ,

The computer works great — as long as it’s plugged in. The battery always shows 80% but the indicator says “battery is not charging”, and the “Power source: Power adapter”. The light will flash green for a second then stay at orange.

I ran the coconut battery app…

I had spilled water on my laptop keyboard and it was working perfectly fine it was charging slower than normal but it was working then today I had went to unplug my laptop and it turned of and wouldn’t turn on but as soon as I plugged it in it turned on idk what to do
