MacBook Pro 13" Function Keys Late 2016: MacBook Pro 2016 屏幕突然黑屏问题

Thu, 06 Jun 2019 18:52:40 -0700

正常使用着的时候电脑屏幕突然变黑，左上角出现一条横白线。并且这种情况可以通过点击右上角的关机键熄灭屏幕，再点击关机键唤醒屏幕即可正常使用。但再过一段时间还会出现这种情况，并且黑屏的左上角的横线会改变颜色。

去授权店进行检修说是屏幕出问题了，后面又去直营店天才吧进行检修，说是可能和系统有关。但是我已经进行过抹盘重装，系统无论是升级到10.4还是10.15都会出现这个问题。

另外我装了双系统，在windows下面没有出现过此种情况。

MacBook Pro 13" Two Thunderbolt Ports 2019: Which T-Con board is compatible with A2159 screen

Hi everyone, I have a 2159 MacBook that turns on perfectly, the backlight works but the screen remains grayish. I assume the problem is the T-CON. I wanted to ask you which T-CON (or even an entire display assembly) of other MacBook models is compatible with my A2159. Thanks in advance!

MacBook Pro 13" Unibody Late 2011: Trackpad erratic and jumping around

Thu, 11 Jun 2026 03:04:19 -0700

Suddenly the mouse of my Macbook Pro started to jump around. The mouse is clicking a lot of stuff out of itself. I tried the following:

- To make sure it is no virus I plugged in a usb mouse which switches of the trackpad.

- According to a lot of forums I had to reset the PRAM/NVRAM, like explained here: http://support.apple.com/kb/PH14222?view...

- I removed the battery to see if it was swollen. I also tested the mbp without the battery in the body to make sure it was not the battery who caused the problem.

- I removed the trackpad and cleaned it with alcohol.

Nothing helped! What is the next step? The strange thing is that after a PRAM reset the mouse will act normal for about 30 minutes. Then the problem starts acting up again.

Any ideas?

MacBook Pro 16" 2021: Machine will not power on - charge light pulses

Tue, 09 Jun 2026 18:32:55 -0700

My kiddo has my old Macbook Pro 16" 2021. They came home from school the other day and opened it up, with no response. They tried plugging it into a charger, but it still wouldn't turn on. Now, the charger they were using was apparently a little chromebook charger... I plugged it in with magsafe to the charger that came with it--the light came on green. I tried holding the power button down for 10 seconds, but the only thing that happened was that the green on the charger turned off, then went to orange. I tried pressing the power button to no avail. After a little bit (maybe 30 seconds?) the charge light smoothly turned off for about a second, then turned back on. This pattern repeated until I unplugged it and plugged it back in. Every time I tried to power it on, I got this pulse pattern, orange on for awhile, short off, back orange for a shorter time, then back to short off, short orange.

I left it plugged in overnight, and the light changed to green at some point, no pulsing. when I tried to turn it on, still nothing on the screen, no caps lock light, no trackpad clicking, but the charge light turned off for a short bit (1s?), then orange for a little longer (10s?) then back to green, which held for about 30s before flipping to off, then orange again, then back to green.

Anyone have any ideas what might be wrong? I'll probably try taking it to the apple store, but it's out of warranty and I suspect all I'll get from them is the "yup, we can send it in for a $700 diagnostic fee."

There seems to be some water damage on the right side usb-c connector. Is it possible to have it changed? Is it removable or does the logic board have to be completely changed. The corrosion is just on the connector pins on the outside.

MacBook Pro 14" Late 2024 M4: Screen Replaced, But Wifi and Bluetooth stopped working

Mon, 08 Jun 2026 05:06:19 -0700

I have MacBook Pro M4 A3112.(Nov'24). this is my first Macbook.

Initially display screen had some damage, so got the screen replaced and i notice both Wifi and Bluetooth has stopped working.

I took back to the repair guy who helped to replace the screen, but he has no clue why Wifi and Bluetooth are not working.

please find the attached the screenshots and photos I took as part of initial diagnosis I could do.

Please advise, what could be the issue and how to resolve this ?

Thanks

Hi @danj

I did reformat whole Macbook and reinstalled OS. Seems issue still persists.

I connected the MacBook to my router using Rj45 cable with the help of connector so I can access wired network connection to internet.

However I tried to do offline diagnostic and I got the error CNW001 . Have attached screenshot.

Power charger wasn't connected to macbook when I ran the diagnostic so the error PPP020 can be ignored in the image here, as I see the MacBook is working fine when charger is connected.

Let me know what option i have to resolve this CNW001 error.

I am using wired connection for Internet for now, not a substantial solution.

Thanks

I used an Ethernet cable and was able to connect to internet.

The pic was taken with ethernet cable on !

MacBook Pro 13" Unibody Early 2011: Charging and Boot Issue

Sun, 07 Jun 2026 15:03:14 -0700

I have a MacBook Pro 13-inch Early 2011. I installed a battery in it, but when I connect the charger, the MagSafe LED turns green, and the MacBook emits a repeating sound approximately every half second. At the same time, a white LED turns on and off repeatedly, and the MacBook does not start.

However, if I disconnect the charger, then press and hold the power button, and while holding it reconnect the charger, then release the power button after a few seconds, the MacBook powers on normally. The problem is that the fan runs at a very high speed, and the green MagSafe LED turns off, although the charger continues to power the MacBook.

I would appreciate it if someone could explain the cause of this issue.

Thank you very much.

Here is the screenshot as requested.

Please note that the MacBook does have a battery installed 😢

MacBook Pro 15" Retina Display Late 2013: Computer unexpectedly shutting down after battery replacement

Sun, 07 Jun 2026 00:26:53 -0700

I recently replaced my battery with an ifixit battery. I calibrated the battery per the instructions, but the computer is unexpectedly shutting down while I still have significant battery life remaining (i.e. 62%). It will restart immediately and will sometimes run for a decent amount of time and sometimes shut down again immediately. It seems to run fine while plugged into the power adapter.

MacBook Pro 14" 2021: Can I replace or fix the microphone?

Sat, 06 Jun 2026 09:59:42 -0700

The microphone on my M1 Macbook Pro is very muffled.

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?

MacBook Pro 13" Two Thunderbolt Ports Late 2020: MacBook 2020 battery stuck at 1% after repair (battery data problems?)

Sat, 06 Jun 2026 05:25:11 -0700

A few months ago the battery died and I replaced it. Unfortunately the repair did not work. When I turn on the Macbook the fans come on full power, and the battery claims to be at 1% with "Service Recommended." There was a brief moment where the battery was detected a few weeks later, but after a factory reset (I bought the laptop off a friend), it has returned to being stuck at 1%.

The Macbook turns on only when it is plugged in, but if I unplug it while it's on, it can stay on for hours (with the fan working at full speed).

Here's what I've done so far:

1. Tried a whole bunch of combinations of draining and then recharging the battery, restarting in recovery mode, etc.
2. Tried two other battery data cables from seemingly reputable companies - I even tried a tape trick to try for a better connection, it did nothing in my case
3. Got a second replacement battery from ifixit (they kindly sent one for free)

So far, none of these attempts have made a difference.

To me, it seems to be an issue with the data transfer from the battery to the rest of the computer, but I think I've ruled out a good number of culprits. Usually, I'm able to figure these problems out on my own, but not this time. Any help would be highly appreciated!

MacBook Pro 16" 2021: Horizontal screen glitches after water damage and repair

Thu, 04 Jun 2026 07:08:56 -0700

So long story short, I wiped my laptop (MBP M1 16") screen with a rag and then cleaned the keyboard in the same go. I used too much liquid apparently, as the keyboard then started producing multiple keypresses and shutdown after booting.

I brought it to a repair shop which then replaced the keyboard but after I took it home, the screen started to flicker weirdly and after 10-15 minutes, went black (not totally, had a weird glassy ghost effect). The next day, the screen did work but there are weird horizontal glitches (not black though) and an area which is kinda sepia in the screen. Using the screen eg. watching Youtube seems to aggravate it.

I took it back to the shop, unsatisfied with their lack of professionalism then went to a different shop and didn't get much out of it except that the screen needs replacing and it's gonna cost a lot (1257€).

So, does anyone have any clue what's wrong with the laptop? Or if there's some way to check what's really broken—nobody has really given me proper explanations. Running diagnostics returns ADP000 (no hardware issues). What !#^&@@ me off the most in this whole debacle was the 1st repair shop's sloppiness in diagnosing the damage before handing it back to me, causing this infuriating back-and-forth.

Here see the horizontal lines in the Finder icon.
