Actually I had no problems until I changed the battery. I changed the battery and ran it, I used it until it had 5% charge left and then I plugged it into the charger.

But, the next day when I turned on the computer, I got the error message that no battery was detected. I tried many things (PRAM & SMC). but the problem is that although it does not recognize the battery, it works with the battery and when I plug in the charging cable, the cable LED does not light up. there is also an excessive fan noise when running on battery and the fan never turns off. When I do SMC reset again, it does not see the battery again, but the cable LED lights Red and the computer shuts down when pulled.

I never tried this method yet just wondering if there is another method possible, the system is running nice and smooth apart from this 'issue'. It seems that I will need to do a clean install again to resolve this. @danj Any Idea on how to 'resolve this'?

I've tried all the suggested online fixes including reset NVRAM, reset SMC, Forced Restart, ran Disk Utility, Safe Mode starts, etc. and so far nothing has worked. Can't find anyone else here (yet, still sorting thru) having the same issue but my guess is it's Display related or possibly motherboard?

I have spilled bit of tea (no sugar) on my MacBook Pro 2015 (top right keyboard area, so around the right fan).

I have switched it off immediately and dried it for 3 days

I have switched it on today, it is working but kinda very slow.

I have IStat Menus:

All stats are looking fine except:

*Intel Iris GPU temperature at 0 degrees.

*High Kernel in my processes (around 500) and high CPU usage.

*High amperage CPU High (CPU, I/O) (95,8 A) and Radeon GPU core (75)

-> When the GPU switch to AMD, temperature is normal (36 degrees).

I have followed the steps from IfixIt to open it and remove the right fan: unplug battery, remove WiFi card, remove the right fan.

Brushed everything around that area with alcohol 96, but the issue is still here.

I do not know what to do as next step…

I feel I could continue the cleaning, bit deeper but I am not sure :-(

Do you have suggestions?

Thanks a lot for your help

EDIT 29.03.2026

Tanks a lot for the help!

I have taken off the logic board and indeed it was bit damaged below. I have cleaned all the impacted areas with iso alcool 96. If you see other areas that I should clean up let me know :)

The TouchID button has a small integrated flex/ribbon cable (labeled "00920-A") that then plugs into a secondary flex/ribbon that extends the original and changes its plug type so it can connect to the logic board under the headphone jack ribbon. That extender cable is labeled with "821-00645-A // MFC0517" and I've been able to find them for sale, but I can't find replacement TouchID sensor anywhere.

Powerbookmedic's listing for the palmrest claimed that the TouchID sensor is not included with the palmrest as they are "married to the logic board". Does that mean that if the TouchID sensor/button is damaged or if its cable is ripped, the ENTIRE LOGIC BOARD needs to be replaced?

Please, somebody, tell me that this isn't true.

Issue video on youtube (don't forget not everytime randomly and less than 250ms): https://youtube.com/shorts/EHbUNVcB7Dg?s...

On macOS 26.2-26.3 and 26.3.1 (Apple Silicon M2 Pro), I am experiencing a very brief (1-frame) UI compositing glitch on the internal display. The issue occurs within a very brief time window (less than 250 ms), but it is extremely disruptive and visually distracting.

- Not thermal or load-related (tested under sustained high load)

- Installing third-party display scaling tools (e.g., BetterDisplay) reduces the frequency but does not eliminate the issue. (BetterDisplay installed on 26.3 but issue was also consistent at 26.2)

- A clean installation performed according to Apple’s official guidelines did not resolve the issue.

Behavior:

- The glitch appears as a brief (single-frame) layer misalignment or compositing artifact.

- It occurs even during light usage such as web browsing.

- It is particularly noticeable and disruptive while using code editors (UI instability is visually distracting).

Frequency:

- The issue repeats continuously.

- Sometimes it happens very frequently.

- Other times it occurs randomly every few minutes or every few hours.

- The behavior appears non-deterministic but persistent over time.

None will allow me to format them (8TB & 16TB).

I formated one of the 16TB on a PC but when I connected to my early 2015 13" MacBook Pro Retina it first saw the external SSD, but then was lost and cannot write to it.

Is the MacBook Pro (A1502) compatible with external MSATA SSD drives?

If not, is there anything I can do so that my MacBook Pro can read and write to these drives?

Thanks.

So I tried replace the battery on the MacBook Pro 2141 and the step where the battery flex cable needed to disconnected by accident I lifted the connector that snapped.

Can new connector be soldered back with ease or this one need more repair?

After some investigation, I'm fairly sure the problem is a blocked grille. But it's hard to identify which (if any) of the hundreds of dimples on the left-hand side are actual holes and therefore need cleaning. Is there any information on this?

the burnt section lifted up where can I find that block and what is it? The one labeled CN

that little CN chip is the only thing ai saw lifted and well with carbon build up. Not sure where to find that number on the board but I have a picture with the serial# and information if that helps some.

Please help me figure this out. Does the keyboard backlight have its separate cable? How is it connected to the motherboard? If anyone has photos of this board and an example of how the power and control for the backlight are organized, I'd appreciate getting those photos. Could I have simply forgotten to reconnect a cable during the MacBook's reassembly?

Thank you, everyone!

some people say the keyboard does vent out heat and that if you put a keyboard cover/skin on that it will eventually wear out (damage) the internal components, others say to monitor hardware temperatures if you cover the keyboard, etc.

all of this seems to indicate then that the keyboard actually vents out heat!??

but where are the vents in the keyboard then? this seems like a completely false rumor! i feel like snopes and we got to get to the bottom of this!

please help me find the truth.

thank you,

I'm experiencing weird issues with my MBP 16" I9 2.3GHZ, 32GB, 1TB, 5500 4GB.

I bought it second hand in October 2024 and due to some strike by Canada Post it stayed for a whole month in a warehouse, dead battery on delivery, the Touch ID was kaput, tried many resets and installs and nothing (no DFU yet).

Some time later, I began having some Kernel Panics here and there, once a month, not so persistent. But lately it began to happen too much in the 10's one after another.

I used it for long gaming sessions with an external ssd ( bootcamp ) not a single crash.

The kernel panics happened a lot when :

Apps running : Chrome, PremierePro, After Effect, Spotify...
Connected to : NVME enclosure, external USB C hub ( 4K HDMI + 2 ext. HDD ), Bluetooth connected to my AV receiver.

Lately I switched to using Safari only and weirdly no more crashes:
NVME enclosure connected + Pr + Ae + Bluetooth active, w/o external USB C HUB

Here is a conversation with Gemini documenting the crashes : https://gemini.google.com/share/e49e55d1...

Gemini is pointing to a faulty power rail or even a faulty T2 Chip ( management + BridgeOs).

I've tried to having some experts to diagnose the issue and all of them gave me the same advice "change the motherboard or better buy a new one".

Louis Rossmann won't be happy with their diagnosis, but yeah I get the struggle of putting in some work and having it fail again.

Right now I sincerely think it's a software issue, I tend to run a lot of renders over Ae & Pr and not a single crash, CPU and temps all high for 1 or two hours, only when an app as Chrome or Spotify ( chromium based app ) runs that I have the unresponsive for sometime before rebooting from a panicked kernel.

The report always states a random unresponsive processes, but I fell like the smoking gun is held by Chrome or Spotify, my proof is simple, they do happen a lot when I push it to the extreme, open new tabs of very taxing website (IG, FB marketplace) the kind of website that has too many layers to it...

Is there anything that I'm missing here ? Faulty hardware acceleration ? I typically run my Mac on dedicated GPU only. Any other hardware ? Or purely some corrupted firmware ( T2 related ).

I'm willing to do a DFU restore in the coming days with another Mac to attempt a recovery of the TouchID and a clean install, even though one quick visit to an Apple Store and they told me it was best to replace it for 200$ ( after a 1 hours diagnosis ).

Tanks again !!
