MacBook Pro 15" Unibody Mid 2010: screen backlight not working on MacBook Pro

Sat, 08 Jan 2022 10:08:10 -0700

One day my screen started flickering then it went black. I thought the lcd / led screen was dead but on further investigation (shining a light through the apple logo) I found that the screen is working fine its the backlight. Now I can not find a clear fix for this. Could I just buy a new screen and all will be well or is it something else I need to look at

thanks

MacBook Core 2 Duo: Headphone Jack Stuck on Digital Out

Mon, 04 Apr 2022 23:14:45 -0700

Has anyone else had this issue where the headphone jack gets stuck in digital out mode?

My speakers are disabled (except for the chime sound when booting), the sound pref panel only allows me to select 'Digital Out' for sound output, and a red light shines out of the jack. Headphones work when I plug 'em in.

I've found other discussions out there about this (such as: http://discussions.apple.com/thread.jspa...), but so far I haven't had much luck with suggestions found there.

Any ideas?

Thanks!

Jeff

MacBook Air 13" Mid 2011: Keyboard Intermittently Non Responsive - Top row of Qwerty only

Sun, 02 Apr 2023 01:26:16 -0700

in the past three months my MacBook and has developed an intermittent problem which has become more frequent.

I now I have to either use my Bluetooth keyboard or dictation!!

It is just the top row of letters, QWERTYUIo... P works!

If I move the keyboard problem, if I type repeatedly and seemingly fill the keyboard buffer the problem goes away.

I have taken my MacBook air to the genius bar, and after running diagnostics they found no hardware problems.

My Mac is running OS X 10.10.5

It's a mid 2011 13 inch 1.8 GHz Intel core I7, with 4 GB of DDR3 RAM

I've tried resetting the PRAM ram, no luck. Similarly the SMC reset.

Everything else runs fine, so I'm reluctant to go buy new machine when this feels like it's a bug.

If anyone has any suggestions, hints or tips - I would be eternally grateful!

I have a 21.5” iMac, 3.06 GHz Core 2 Duo with a ATI Radeon HD 4670 256MB graphics card.

I was wondering if I can upgrade the graphics card to a more powerful one, maybe to the ATI Radeon HD 4850 graphics with 512MB.

And if so, are there step by step instructions on how to do it?

MacBook Pro 15" Touch Bar Late 2016: Horizontal lines on display unless lid half closed

Mon, 23 Oct 2023 19:22:59 -0700

This is my work computer that lives in my drawer. No wear and tear to speak of (other than opening and closing the lid). Opened the lid mid-day one day and horizontal lines completely cover the display.

If I slowly close the lid to about half way, the lines will disappear.

Only to reappear when the lid is opened again. Obviously a connection problem. This is a work computer and the repair shop quoted work $3000+ for this repair. Ludicrous. Also, no apple care was purchased so this barely-more-than-a-year-old top of the line Apple computer is suddenly worthless.

I'm not afraid to open the case, but could someone direct me to the cable that I should unseat and reseat, or perhaps even replace?

Any help greatly appreciated.

MacBook Pro 15" Unibody Mid 2010: Problem with NVIDIA GeForce GT 330M 256 MB?

Sun, 21 Feb 2021 15:26:00 -0700

I have never had a problem with this machine until 2 months ago when it began to crash badly (black screen) and frequently. I found one answer -- to disable switching between ordinary graphics and hi quality graphics. I disabled the switching so that the hi quality graphics is always in use and the crashing went nearly to zero. I also disconnected the 2nd monitor I was using. But I am still experiencing random seeming crashes and the reports seem to indicate graphics problems. Is anything to be done? or am I looking at a total replacement? (I also took it to the local Genius Bar and as was reported here, their tests did not detect any problem!)

MacBook Pro 15" Unibody Late 2008 and Early 2009: How to repair a bent corner of the aluminum lid?

Wed, 08 Nov 2023 13:44:30 -0700

Long story short, I accidentally dropped my MacBook Pro. It hit the ground and bent the corner of the aluminum of the lid. My computer works fine and the screen is fine, so this is merely a cosmetic question. How can I bend it back? Since it is aluminum I am guessing that I should be able to bend this back and solve my issue. For a $2000 computer designed with aesthetics as part of the appeal, I would like to fix this without getting ripped off $600 by apple.

I am sure this happens everyday, so this is not a knew question, but I am still curious if there is a DIY fix.

Mac: re installing OSX problems

Sat, 24 Jun 2023 15:24:45 -0700

Does anyone know why its becoming nearly impossible to do fresh installs of OS-X on older Mac Systems.

I have had a collection of various versions of OS-X installs set up on USB sticks. Have been using them with no bother for the past 5 + years. In the last 6-12 months they have all stopped working.

When I try to re-burn them and use them the Mac system is saying the install has become corrupt.

The current issue is with a customers MacBook Pro, the 500GB mechanical HDD has died. Have fitted a 480GB SSD and tried using the internet recovery to install Mountain Lion.

After formatting the drive and starting the install i get a timer stating its going to take -2,393,938,938 and 8 minutes. After about 2mins it pops up saying Can’t download the additional components needed to install Mac OS-X. I have tried it with a standard mechanical HDD as well as the SSD.

MacBook Unibody Model A1278: Audio jack problem, no speaker sound, red light

My MacBook has no sound except through headphones or external speakers. When I play a song, a red light appears inside my audio jack and there's no sound. The volume controller in the menu bar is grayed out. I tried poking into the audio input jack as mentioned in many forums, with no luck. Can I fix it by opening my MacBook? Is there any way to fix this other than poking something into the audio jack?

MacBook Pro 13" Retina Display Early 2015: Keyboard and trackpad are unreponsive?

Wed, 17 Sep 2025 20:52:45 -0700

For some reason my macbook keyboard and trackpad are completely non-responsive. I know for a fact that the keyboard and trackpad are not the problem.

Here are some other things I have tried:

1) External keyboard and mouse work perfectly fine. I can log into OS X and everything functions normally with an external keyboard and mouse.

2) I performed an SMC reset using the built in keyboard. As I said, I know the keyboard is good.

3) I can not reset the PRAM using the built in keyboard. I can reset the PRAM with the external keyboard.

4) I have tried to leave the Macbook working till the battery dies then leave it for one night without charging and afterwards restarting it with power supply plugged in and they worked but afterwards they in s random startup they return unresponsive (I have tried this for two times and worked and I trying my third time now)

Please don't fixate on replacing the keyboard and trackpad.

The keyboard works before the chime (SMC reset) and does not work after the chime (can not reset PRAM). It seems like the logic board is turning off the keyboard when it chimes. Not sure what could cause this. Does anyone have any ideas?
