If I purchased the 4GB model of the new MacBook Air that just came out, could I upgrade the RAM to 8GB myself?

Thanks,

Alex

My macbook air 13" Mid 2012 keeps on turning off abruptly when unplugged. It can last from anywhere around 2 minutes, to nothing (a small sound appears when powering on, yet cuts off even before booting sound). Initially it would last longer, yet quickly degraded to its current status.

However, when plugged in, it works with no problem at all...

I initially thought the battery must have degraded really, really quickly (i replaced it about 2-3 months ago), yet as can be seen with coconut, its in good health with realtively few cycles.

I hace done an smc reset with no results.

I have also done pram, no results.

I have run diagnostics, no faults appear.

I have attempted completely discharging battery, but as it turns off when unplugged, this is something I can not do.

What I am guessing (in light that the battery actually comes up as "good") is that the laptop somehow thinks that it is drawing too much power and thus automatically closing itself. When plugged, there is infinite power so it doesnt feel the need to close itself, even if it might see itself drawing too much power.

I think this might be the issue because the problem slowly started after very heavy usage of playing CIV 6 for a week where it was surely gobbling up power. Now the component that measures this "power-gobbling" (:)) rate is either broken or uncalibrated as a result of this heavy use.

But of course this is purely a guestimate...

It would be much appreciated if someone helped me out!!

My Mum dropped some coffee on top of her Macbook Air. I managed to open it, dry it and cleant it with Isopropyl Alcohol 99%. After a few days of drying the computer booted up but I never got it to charge the battery or work with AC Adapter. It worked until the battery was drained and nothing has happened ever since.

Any ideas on where shall I start testing? I already bought a new IO Board which didn't work so it's clearly not that.

I got the schematics of the board but I have no idea where I should start testing. Does someone has any idea?

In mid august I bought the new Macbook air 13" Intel Core i5 for education use. And for the last 2 months I have been using it fulltime at the university. This means I have a lot of very emportent and irreplaceable notes and papers on my hard drive.

So here is the thing! Last week my Mac had a water damage in my computer bag and the screen is now burned out.. My insurance won't cover a new one and before I have the money, I need to recover all my files from my hard drive because I need them i school! I have looked for an adapter that I can use to connect the hard drive to another machine but because of the new product it is impossible to find!

Can anybody help me? I am desperate to find a way to get to my files!

From a hopefull Mac-user!

I booted from a Mountain Lion flash drive and ran Disk Utility, but it does not see the hard drive. I also tried booting from the network recovery with the same results and ran the Apple Hardware Test, which showed no problems.

I haven't been able to check if something happened to the connection between the drive and the logic board due to the pentalobe screws (I already ordered a set of drivers). Is it possible the the hard drive is not completely dead and the information can be recovered? (It's still in warranty and I could take it to the Apple store). Could it be the connector or logic board? Is there any other test I can run without tearing it apart?

If I manage to pull out the drive, is there an enclosure that I can use to test if the issue is not with the drive itself? If I take to Apple and they replace the drive, will they give me the old one to try and recover data?

Thanks for any ideas you can provide.

Fernando

Edit. Found the OWC case and will order it if there's a chance of recovering the data.

My Mac was functioning wonderful until, I upgraded to yosemite suddenly the audio input/output devices aren't detected! I have tried all the trouble shooting steps online NVRAM, PRAM to clean install of the software back to mountain lion and now running mavericks, but all in vain!

Took it to the authorized service centre they failed to diagnise my problem and detected fault on MLB (Main Logic Board) for which they are charging a bomb!

I would like to know if there is any work around to get the sound working! I read about external audio devices which doesn't require any drivers come in handy (Sabrent) should I settle for this? I am confused and frustrated with my MacBook Pro! Please HELP!

TIA

Hope someone here can help with my situation as described below and thanks in advance.

I spilled almost a cup of water on my macbook air last Saturday. I tried to turn it off immediately but it wouldn't turn off and the fan was on high speed for about 5 mins until it turned itself off.

I put it in a rice bag for 2 days and then put it in a room with heater on for a few more days since we haven't had any sunlight this week (really bad timing). I just turned it on today. Everything - display, fan, temperature, keybaord backlit, speakers - is working perfectly fine except the battery. The light on the charger is orange but the battery menu says:

Condition: Replace Now

Battery is Not Charging

Power Source: Power Adapter

I also ran Coconut battery app and it read:

+ Battery Charge

Current charge: 0 mAh

Max charge: 0 mAh

-9.223392e+ 18% (in the progress bar)

+ Battery capacity

Current capacity: 0 mAh

Design capacity: 6700 mAh

0% (in the progress bar)

I'm wondering if anyone knows if it's the problem with the battery itself, the logic board or something else. I don't want to buy a replacement battery only to find it is something completely different.

Any help would be much appreciated :)

Thanks,

I have a Macbook Air mid 2012 with the LCD working fine but the LED Backlight it`s not turning on. So, I live in Brazil and going to stay in the US for a few days, then...

Can anyone tell me where i can find and buy the parts that might be damaged in the LogicBoard?

I don`t mind to buy all the possible parts that might be damaged and replace just the damaged one when i get home since this parts is cheap compared to buy the entire logic board!

I dont know where to buy this parts, but reading online, here is what I possible need:

1. F9700 Fuse

2. The Mosfets Q9706 and Q9707

3. ?

Does anyone know any other part that might be the problem? I know that the problem can be everywhere in the logic board, but let`s be fair, I`m trying to buy the parts that mostly common are the reason for the problem with the LED backlight ok?

Thank you so much to all the iFixit Community!

I'm in doubt that the schematic is the final version and want to know for sure that the power rail is really suppose to be 18,5v before I set 18,5v from my power supply on the rail to find the short.

Can somebody confirm that this macbook uses 18,5v and not 16,6v?

A hardware test shows a failure of "4BAT/1/40000000 0x898f3790"

Will a new battery fix this problem? Or does it need a new logic board?

⟐ Commented April 01, 2016 at 8:10 MST

My motherboard is gone due to a spill (advice: if you spill something in the macbook, just bring it in a repair shop for cleanup, as mine lasted 6 more month but would have been OK if I had cleaned it properly).

Anyway, since I am replacing logic board and top cover anyway, I thought I might put in 2.0Ghz i7 with 8GB of RAM instead of the original 1.86Ghz and 4GB.

Are there any incompatibilities between the logic boards of the same year if I put higher end internals? Given that the logic board that I replace with is from a MacBook Air 2012 A1466 same as mine..

Any thoughts? :)

I have a 13" Mid 2012 Macbook Air that has stopped turning on.

I have tried multiple known good chargers - no light on any of them.

SMC Reset, unplug battery + power button all did not help.

No activity at all upon powering on. There are NO battery status indicators on this model to tell if battery is charged at all..

I assume that it is either the logic board or the I/O..

Is there a way to isolate this between a faulty logicboard and a faulty I/O Board?

I understand the $90 I/O Board would be a better place to start then the $400 logic board - but was curious if there was anything I could do to test for sure which is the failed component. Is there a way to send power to logic board bypassing the I/O Board? It's likely the battery is completely discharged so I don't think shorting the pads did not seem to work, due to I'm guessing no power in the system.

Thanks in advance
