[MBP 16" 2021, A2485] No signs of life after a successful first boot and closing the bottom lid with screws??

Hi all, I'll be as detailed as I can be.

I replaced my keyboard with the backlight and all was working perfectly on my Macbook Pro after a repair job (only swapped the keyboard and backlight out, but broke Touch ID ribbon cable in the process so I ordered a new one to use only as power button (touch ID isnt working anymore)). I'll state when i tightened all the screws as tight as they could go on power button with the metal plate, the button wouldnt press, so I left those 4 screws on the button just a bit loose, and it worked fine to depress and let the button rebound like normal.

I put in 2 screws to hold the bottom panel on, plugged it into a charger, did first boot, tested everything and everything worked flawlessly! I removed my fingerprint from settings, I lock the screen and test the new power button and it works fine. I turn the machine off via shut down in the top left menu bar. I thought it was a job finished. I turned it over, and put it almost all the screws but was really struggling to put one of the long screws in the top right (it kept going in crooked). I took off the bottom panel again, put the screw in just the hole to ensure the threads werent ripped in the screwhole and that it was fine. It went in fine.

I put the back panel back on, manage to get the screws all situated in their respective screwholes, and now I go over to press the power button on my macbook pro? Nothing. 0 Life. I plug in the charger (magsafe and I've tried all the USB C ports) absolutely zero life..

I've tried:

- Holding Power button for 10 seconds without or without chargers

- SMC reset (ctrl+shift+option+power)

- Reseating magsafe connectors

- Reseating ribbon cable with its large screw

- Leaving battery unplugged all night, then tightening it again and trying to turn it on next day

- Checking that all connections look fully plugged in

I'm at a loss on what happened. Did I short something when I tested that screw in the screwhole? I have a multimeter, soldering iron, and am fairly technical if anyone has any recommendations on where to test on the board for any potential problematic components/areas.

Thanks guys.

Macbook Pro A1990 dead after battery replacement

Just finished a macbook pro A1990 battery replacement. While I was connecting the new battery, I heard a slight spark sound and a slightly off smell. Now when I plug the device into the charger, nothing comes up. Theres no sign of power at all to the device. I did change it with an ebay battery, if that info helps. I left it charging for a bit, reseated the battery, did all the reset keys and not even a slight sign of power. I tried reconnecting the old battery for a second by holding the connector together and nothing came up. Did I fry the board? Or is it just some weird issue needing to be worked out? Not sure what to test with the multimeter or seeing if I let it charge for half an hour will fix the issue. Any help?

Dustgate?

Apparently, today I found this gate called "dust gate". I think this is happening to my MacBook Air M1 because it has the same symptoms of dust gate and it is common in MacBook Air M1s. I just bought some tools to see if I can open it and try to clean it and see if that works because I do not know how to solder. It's a slim chance that it will work but it's worth a try since I'm super tired of just putting it at an angle where it will work. If this doesn't work I might just buy a for parts MacBook and use that screen.

Macbook Air M2 Not sleeping when i close the lid

I recently replaced my screen, so I had to transplant the old LAS to the new screen. Now my laptop is not sleeping when it's closed. I was thinking that if the connection to the mobo wasn't working then the laptop just wouldn't turn on at all, but it's working fine except for this one bug. Any help would be appreciated, thank you

Circle on Macon air battery (intel 2020)

Found this circle on a battery after taking a look underneath because it’s not holding a charge. It’s kind of old at this point and hasn’t been used in over a year, but my friend wanted to try and get a file off of it and it’s been running really slow. I couldn’t find any information on something that looked like this, and the rest of the battery isn’t inflated, but I wanna double check and make sure just in case.

Need to disable Headphone Jack/Digital Out completely on 2009 MacBook

Hiya gang! Hope all is well.
So recently I got my pop's old 2009 MacBook, seems to be working well except for one thing: There's no sound. I eventually found out that it's because the headphone jack is jammed with a broken plug. In trying to remove it ranging from a toothpick with glue to a full on power drill, I haven't managed to make any improvements. Now I found out that you can make it play out of the speakers by holding "Option" on the sound device panel, but occasionally it'll switch back to the broken headphone jack again.
Now, on to the meat & potatoes: I need to find a way to permanently disable the headphone jack, make the Mac think it doesn't even have one. Preferably through software, though if simply removing the thing would work then that'd be fine. Is there ANY way I can make the Mac forget the headphone jack permanently? Any boot parameters I can set up in the terminal, any software I can install, any modifications I can make? Any & all help is apreceated, thanks in advance!

Macbook air 2015 or 2016 screen

Hi everyone,

I wanted to give my Macbook air 2015 or 16 a new life by installing Linux on it.

When i turned it on to see if it works in the first place i heard the turning on sound. I see a small faded apple logo. And then darkness, except the keyboard lighting.

Does this mean its fully dead or can i try some things?

Thoughts on this second hand M3 max?

I'm looking at a 2nd-hand M3 Max MacBook Pro from a physical shop. The seller admitted he opened the bottom case to "verify the internals were legit" before he bought it from the first owner (the seller I am buying from is a reseller)

Specs & Data from my inspection:

Model: M3 Max (16-core CPU / 40-core GPU), 48GB RAM, 16-inch.
OS: macOS Sequoia 15.1.5.
Battery: 447 Cycles, 87% Maximum Capacity (Condition: Normal).
Diagnostics: Ran Apple Diagnostics (D-key on boot); result was ADP000 (No issues found).
Parts History: No "Parts and Service" section appears in the "About" menu.
Activation Lock: Disabled.

My Questions for the experts:

Is it common/legit for a dealer to open an M3 Max just to "check it," or is this a cover story for a repair?
If the diagnostics says "No Issues" and "No Parts History," can I trust that the internals are 100% original even if the bottom screws were turned?
What specific hardware "stress test" should I run in the shop (which also runs fast) to see if the performance is like original and that thermal paste or cooling wasn't messed up when it was opened?

Sorry if I missed anything

my MacBook M1 pro 16’ screen has been acting weird lately

few days ago some vertical lines suddenly appeared , then later the whole display glitched out and went completely black. I thought it was dead for sure.

A day later I opened the lid ,the screen glitched again but the glitch was more “colorful” this time… and somehow a few hours later the screen was back to normal like nothing happened but the vertical lines are still there

Now I’m not sure if it’s a temporary glitch or if the display is on its way out. Has anyone had something like this happen before?

macbook air screen after repair

hi all. recently got my screen replaced because it cracked (not physically, which is weird, but i know these screens are delicate) and got it back. everything was fine till i noticed the outer ring was lighting up with the actual screen and it never did this before. i’m a teenager and had to pay ~300 for this repair and kinda upset that the end result was a little cheap looking

Battery help for MBA M4

So I got this machine back in the first week of October last year and ofcourse it's brand new(Almost 7 months old now). Now at first I used to get over 8hrs of screen time after a full charge and that is counting only till 20%. then slowly idk it slowly became 7ish but that was mostly cuz of my work flow I think. I was learning blender and editing videos. and at the same time coding with it. so that means my average screentime is somewhere around 10hrs a day cuz of my job and stuff

only recently I started noticing the battery life has fallen significantly low. and it's happening this month or I've been noticing it this month...

I'm only getting 5hrs of total screen time maybe five and a half. that said my laptop is constantly warm as the temperature in my surrounding is always 30-38C all the time. So I figured that might be the problem. but to be sure I kind of ran a test last night.

Cool environment(AC), Full charge no apps running except safari and a few tabs and started using it at 22.30 at 100% and by 23:39 it was 87 then by 00.20 it was 76 and rn it's 2 am and I'm at 39%. all at a few safari tabs and a few apps running in background and no, no heavy apps are running.

I checked the battery health and

cycle count 176

total capacity 4629

available 4395

that's rougly 95% battery health. that doesn't explain a 5hrs of total life with a really light use case

Now I know I'm panicking for nothing and it isn't serious but hear me out. It's one of my first mac device and I've heard so many good things about the battery and 5 hours of screen time with no big time use makes no sense at all to me. I use the beta version too btw. Please lmk if it's normal or should I get it checked

2017 MacBook Pro stuck in startup loop

I factory reset my MacBook because I wanted to sell it then out of nowhere it got stuck in a startup loop. I’ve tried everything on the internet (disk utility, bootable drive, internet recovery, apple support) and I’ve had no help with it. How do I go about fixing it? Should I just recycle it?
