I have a 1st gen MacBook Air here that doesn‘t turn on anymore, but the battery will most likely be dead. But also when I‘m connecting the power cable it doesn‘t turn on and the light on the power cable is always off.

Does that mean the charger is broken or is it more likely that something else is broken?

The MacBook runs fine from the power supply, but the battery will not charge and the computer will not run from the battery (even though a battery is present, working, and has over 60% charge). MacOS shows no battery present.

Running Mac Hardware Test results in error code:

Error code: 4SNS/1/40000001: TB1T-0.000

This is a temperature sensor error and - I presume - therefore the battery temperature sensor?

The question then is what, if anything, could be done about this?

I have searched widely but cannot find where the battery temperature sensor is located on an A1304. Any tips most welcome!

These photos illustrate the problem:

Coconut Battery - note the temperature!

No battery recognised in MacOS

System Report

But when booting with Ubuntu...

Battery is recognised - and has charge, but is NOT charging (MagSafe shows green LED)

More detail

Further update

The question was raised below if this was simply a battery problem. No - the same happens with other batteries I have tried, and the batteries are new or new-ish. These two screenshots show Coconut Battery and the Ubuntu battery overview - but with a different battery installed. The same faulty temperature reading in Coconut Battery.

Do I need a New keyboard with power button?

Laptop does not come on. If I disconnect the battery, then plug the laptop in, and wait a moment, then the laptop comes on, without me pushing the power button.

The internal SSD is blank, so I went to reinstall macOS lion and found that both the keyboard and the keyboard backlight aren’t working. I have also tried a USB keyboard.

After opening up the laptop it looks like maybe the keyboard may have some light water damage. Would replacing the top case fix the non working keyboard? The logic board looks perfect and doesn’t have any traces of water damage.

Is there anyway to force the Mac to boot from usb without the use of the option key? I just want to test the Mac to make sure it works before spending any money on parts.

My laptop is not charging when I plug it in. I've tried plugging in and out the charging port, and I tested the charger with another laptop. There's no visible damage on the charging port either, it seems perfectly fine. The light isn't lighting up on the charger, even though it does on the other one. What could be wrong?

It ran out of battery ages ago. Also, the display wire, hinges and clutch cover are broken.

How do I read it.

Get an 1.8" enclosure?

What do you suggest any links?

What's the difference between ZIF & LIF?

What the easiest cheapest just want to wipe the drive & put it back into

sell the parts on.

Is this drive enclosure the thing to buy?

Amazon - DELOCK Gehaeuse 1.8 micro SATA USB 3.0

Delock Product Page - Further Specification.

Can anyone confirm? It looks like it can do the job.

I have a problem, i have an old A1237 MacBook Air with 1.6Ghz Intel Core2Duo an 80GB HDD. MacOsX 10.6 and Windows 7.

When it boots up it gives the original apple chimme, after it shows grey screen and in a couple-o-minutes tries to load a broken copy of Windows 7. When you try to press hotkey's like ALT, "C", Command + V, +T or other, while booting up, nothing happens - like that the keyboard is not working or detached. But when it tries to boot up windows - the keyboard starts to work (Capslock green light works).

How can i fix this problem?? How can i factory restore my Mac to MacOsX??

Tried all hotkey combinations while booting - nothing works,

Tried detaching internal HDD and booting off USB holding C or ALT - shows Apple logo and in a couple-o-seconds starts to blink and show a folder with "?" or a crossed circle. Used Original USB recovery drive and one MacOsX Lion install USB flash drive made by other MacBook.

.....waiting for an any ideas....

Any ideas?

On power up, my MacBook Air beeps three times continuously.

beep beep beep (short break) beep beep beep (short break)....

Any ideas.

Frustrated!!

I feel really ripped off! I bought the macbook Air 13" shortly after the warranty expired. The thing is practically perfect. Now I come to find out that the ram is bad and there's not a thing I can do about it. I tried to to Hold Command +P+R and still nothing.

I also have a new 10.6 installation disk but I can't get the 10.5 disk out of the external drive.

Why am I getting the "cannot install on this computer" message and how do I correctly install the 10.5 software?

How do I eject a startup disk from the external drive when the install disk is not available to Eject or the Drive itself cannot be ejected because the disk could not be unmounted?

Thank you

(I know the 60w and 85w Magsafe power adapters have a different form factor and that the MacBook Air can't sit flat on a surface if you use them -- I'm just curious if it's safe to use them on my MacBook Air.)

Thanks!

The screen is blank and there is no processor or hard drive activity while it beeps.

I have tried the 'CMD+R+P' and press and hold 'D' boots without any success.

This is most likely a RAM issue but since the RAM is soldered on, I cannot reset it as most guides have mentioned.

This is what the motherboard looks like: http://imgur.com/a/ZYy1l#0

Any help would be really appreciated.

Thanks in advance!
