Replace Wifi/Bluetooth cable without Isight

Hi Everyone,

Will try to get straight to the point. While trying to add an additional drive utilizing the optical drive of my late 2008 Macbook Pro 15” I noticed some odd behaviour after installation:

The fans run high constantly - even after NVRAM and SMC reset
When shutting down via finder the machine boots down and then turns on again on its own
The machine also boots up automatically when the magsafe cable is connected
The wifi and camera does not work - Bluetooth works

After close inspection I noticed that the isight/wifi/bluetooth cable that connects to the logic board maybe damaged which maybe causing these issues, based on what I have read elsewhere:

https://forums.macrumors.com/threads/mac...

I don’t care so much about the isight camera or the bluetooth. As a matter of fact, even if the wifi doesn’t work I can always use a USB adapter. My concern is more to resolve these additional oddities.

I will try disconnecting/disabling the airport connection see if it solves the issue.

My main question is, if I were to get a new isight/wifi/bluetooth cable could I connect the wifi/bluetooth without the isight? Reason being is that from what I can gather, replacing the isight involves taking the LCD apart where as replacing the wifi and bluetooth is relatively easier and just requires access to the wifi/bluetooth card where the lid hinges. Since the cable is all one piece could I not just remove the isight portion and tape the exposed portion up?

Let me know your thoughts. They are much appreciated.

Lets backup here... Have you tried running diagnostics?

Restart your system and press the D key Mac startup key combinations

let us know what the error codes you got

Thanks for the reply Dan.

Tried pressing the D key but no luck. Also tried command+D and option+D without any luck.

Thanks Dan,

I ran the test and got 4SNS/ 1 /40000000: TB3T - 128.000. I realized after that this was with a new battery I installed so I installed the previous battery and ran the test again and got 4SNS/ 1 /40000000: TG1H - 128.000

The error you got 4SNS/ 1 /40000000: TB3T tells us you have a sensor error 4SNS its a temp sensor T and it’s within the battery B. So your replacement battery has a defect as this shouldn’t be a failure.

As far as when you plugged in the original battery error 4SNS/ 1 /40000000: TG1H. Here again you have a sensor failure 4SNS as well as a temp sensor T in this case the G is Graphics. This is not good ;-{

NVIDIA GeForce 9600M GT dedicated graphics chip thermal sensor is firing off. This could be due to the lack of cooling as the thermal paste is worn-out or the heat sink coolant has leaked out. And, lastly the chip its self has an internal failure. cleaning and applying a fresh coat of thermal paste is a good start but I would recommend you get a good thermal monitoring app like TG Pro You’ll need to fire off an email to support (at) tunabelly.com to get the older version which runs on your version of OS-X (the highest version of OS-X your system supports is El Capitan OS-X 10.11.x).

Just make sure you don’t over do the paste! You just want enough to cover the chip die alone.

Reference: How to run and interpret Apple’s Hardware Tests on your Mac

You also need to return your replacement battery (if its still covered) as its got an issue too! You might want to get the older version of CoconutBattery again contact chris (at) coconut-flavour.com to get the needed version for your OS-X.

Thanks for the prompt and thorough response, even if it's not what I wanted to hear :( Will have to weigh my options at this point as this is becoming more than I bargained for.

Out of curiosity, would this also contribute to the the issues mentioned above:

- The fans run high constantly - makes sense given the issue with the sensors

- When shutting down via finder the machine boots down and then turns on again on its own

- The machine also boots up automatically when the magsafe cable is connected

- wifi and isight camera not working

Sucks because the above issues did not exist prior to the attempt of the adding the additional SSD and upgrading RAM to 8GB using 2x4GB DDR3 Corsair CMSA8GX3M2A1066C7. Don't think this would contribute to the issue since system recognized the updated RAM without any issues.

The only thing here I can see is putting in the wrong SSD. Most SSD's are fixed at SATA III (6.0 Gb/s) speed which is too fast for your system. Your systems SATA Port is only SATA II (3.0 Gb/s). You need an auto sense drive like a Samsung 860 EVO which will match your systems I/O speed. Check your SSD spec sheet does it clearly state it supports SATA II like Samsung's does? If not then you need a different SSD.

Even still that doesn't fully explain your issues you are facing here. Put back your original drive did that alter anything?

7 дек 2019 г. из Dan

These tests are with the original drive. I removed the SSD as the drive crashed a couple times when I was cloning to it so wanted to isolate it the issue.

7 дек 2019 г. из Richard

Well, that explains the crashing with the SSD!

I don't clone! Gave up with it years ago. I've had more issues with it than following Apples process. Installing a clean OS using a OS installer drive (FireWire or USB here). Then use Migration Assistant to move the user accounts, apps and data over.

UPDATE

Just for fun I unplugged the isight/wifi/bluetooth cable as recommenced in another forum and the issues mentioned above were resolved.

- Fans speed back to normal

- Shutdown through finder and does not auto reboot

- does not boot up automatically when the magsafe cable is connected

Will try running the diagnostics again to see if anything changes.
