MacBook Pro 4,1 shorted out via case around screen.
Hello all, and thanks for any help!
MAcbook pro 4,1 (Early 2008, 2.4 ghz core 2 duo, I think either A1226 or A1260)
Earlier tonight, my MacBook Pro shorted out when the outer case surrounding the lcd touched another metal component on the desk of the sound booth at my church. It was powered on, plugged in via MagSafe, and the battery was connected. The other component was uneffected, but the MB immediately crashed, while simultaneously creating sparks. It will not turn on at all (not even the fans will spin up) under these circumstances: battery and MagSafe connected, only battery connected, only power supply connected.
I've opened it up (it's well out of warranty by now) and everything appears to look ok. I've read that the culprit could be the left IO board not supplying power to the computer, but I'd think it would start under the battery if that was the only problem. I'm beginning to suspect the mother board because I know the one for this model has been known to have issues.
Any thoughts? Would I be better off to get a newer refurbished MacBook when weighed against repair costs?
Thanks!
"touched another metal component on the desk of the sound booth"
What was the other metal component?
You should definitely measure possible voltage between that "metal component" and a good ground. A cold water pipe would be the best. If it 's not plastic. Check for both AC and DC because that sounds dangerous!
As for the MBP:
What is the state of the charger light? Battery LEDs?
Try resetting SMC by disconnecting the battery and pushing the power button for 10 seconds with the power adapter disconnected. Then try a restart.

I bought an HDTV cable to connect my MacBook Pro to my Sony TV via HDML. The TV recognizes my computer; I see my basic computer screen on the TV. I tried to watch videos on my TV but got nothing. (tried via my facebook vidoes and Youtube. What am I doing wrong?
I've got a similar (but different!) problem: I have a MacBookPro3,1 running Mac OS X 10.6.8. I want to connect to my HD TV using a HDMI to DVI cable but the MBP cannot detect the TV display. What's the solution? Is this a bug in Mac OS X 10.6.8 ? Any ideas what I can do to make things work with the HDMI to DVI cable. (N.B.: I have separate audio cable running from the MBP to amplified speakers for the sound side of things. It’s the video that’s the problem!)

How can I access files that I moved from an older MacBook Pro to a newer one via Firewire and Migration assistant? The files show up on the new MacBook but cannot be opened. Thanks!
Get info then check permissions then add your curent user name (it was probably different on old Mac) and give your username full read/write permissions.

my macbook pro is connected to internet via my time capsule but my iPad and iPhone won't. it shows wifi connection to the time capsule but when i go on to the internet on the iPad or iPhone, it comes up with network error. can anyone help?
This can be caused by a number of issues.
Was everything working and then suddenly stopped??
Or is this a new clean setup and has never worked.
Do you have a cable modem which is not a router and the TC setup in bridge? That will cause it. The TC must be in router mode, ie dhcp and nat.
Check the IP the MBP gets including dns and gateway..
Then check the ipad/iphone.. post what IP dns and gateway (router in applespeak) they get. -
My MacBook Pro will not open documents via Adobe Reader. Says I need to aspen Reader in Browzer and accept terms and contitions first. Went through this 3 times and got through to "Finish", closed browser and then retried. No luck. What's going on?? Have no problem with same documents on iPhone and iPad
After you finished installing did you launch Adobe Reader from your /Applications folder and accept EULA(End User License Agreement)?
What is your Adobe Reader version?
What browser are you using and browser version?
Thank You. -

You are still under warranty. Call Apple Care. -
When I am listening to the radio (streaming through itunes) my macbook pro will log me out, quitting all the applications I have running (often firefox, word processing, itunes, etc). Why?
It's very frustrating and I don't understand why it happens. It might happen other times, but I notice it the most when I'm streaming the radio through itunes, though I think it's also happened when I'm streaming music or shows from NPR, so I don't actually know if it's an itunes thing, or an internet thing? Or just my computer being stupid? But how can I fix it?
Thanks!My best guess at this point is a problem wwith 10.5.8
It seems clear to me that sometimes, seemingly randomly, software will access the video card (flash player, quicktime, Safari's HTML5 video player, etc) and it will cause a freeze and then log out.
However - it could just be video card + processor under load.
This didnt happen before 10.5.8 and I'm thinking it's not the new 27" display causing the issue.
I'm going to attempt to find time to revert back to 10.5.0 and then combo update back up to 10.5.7 which may be difficult as our IT is remote and we don't have access to Snow Leopard discs.
I may just have to bring my own in. -

My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?
My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?
Odd how this hasn't been archived yet.
I'm getting the same thing with my Macbook, but can't boot past the white screen. An Apple store in KS suggested I needed a new hard drive, but I've already put two in there and it's still doing the same thing. I really don't want to buy another motherboard like I had to a couple of years ago.
My choices are either buy a cheap drive to boot from and remove the current one to put into an external case, or save the money by not buying a new motherboard and putting it as a down payment toward a Mac mini. -
Does anyone have any advise when a Macbook Pro doesn't boot and has a blank screen? The fan is running but there are no backlights working.
Depending on your model MBP, see Article: http://support.apple.com/kb/TS2377 MacBook Pro: Distorted video or no video issues These computers were manufactured between approximately May 2007 and September 2008
If you are under warranty and/or have AC, give them a call.
Out of warranty, take your MBP to your local AS and/or AASP. -
When I turn on my MacBook Pro and when I am at the login screen, the background is white rather than steel gray. What is wrong and how can I fix it?
It turns out that iCloud caused this issue. When I turned iCloud off my login screen was completely normal.

How do I fix a initializing problem with my macbook pro? I only get to the blank screen with the apple logo and the "processing something" sign... it just doesn't start the system....
Please help
MarceloIf there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
Gray, Blue or White screen at boot, w/spinner/progress bar
Also take this time to backup your users files off the machine if possible.
Most commonly used backup methods
Sometime that won't work and you need to do more

I purchased Macbook Pro i5 in March 2011. Now the screen has problem; one vertical blue line is in the screen (at the right side). I noticed this last week when I opened the macbook and now I am always seening it. I am seeing the blue vertical line always in the screen. However, I am not seeing this line when I open Word, Excel, PowerPoint files (without pictures). But I am seeing this line always when I see movies, pictures, and all the files which have pictures. Please do let me know how can I remove this vertical blue line (blue tint) pernamentally from the screen.
Regards,
UjjalBackup your files to a external hard drive and disconnect.
Call Apple and make a warranty call, then take it to the nearest Apple Store etc.
