Apple PB 520

It's old, I know, but the screen has begun to flicker as if something had become loose. Can I open it and see if something disconnected? How?

Sure, the warranty on that machine was up over 10 yrs ago. Those laptop had a going life of 7-8 years, the internal hard drive that shipped with it, 4 at the most. It's called wear and tear and parts being outdated. So it comes down to how much your time is worth, what is it you choose to gain and the law of diminishing returns.

Model number A1286. My mac cannot turn on when I try to turn it on it just sounds like its warming up but the screen is all black, what do I do?


This is a very unusual symptom of hardware failure. One or more of the following might be the cause.

The ribbon cable to the display has worked loose or its connection has otherwise become interrupted. This seems the most likely; most other problems would at least show a "gray" screen during startup.

The GPU (graphics card) has come loose or (very unlikely) has died.

If you (or someone you trust) are not comfortable opening it up and checking for loose connections, you can try taking it in to an Apple store for assessment, but this model is considered "vintage" and no longer supported.

Just for reference, I'll include a link to several videos which explain the breakdown process in detail. (http://www.powerbookmedic.com/manual.php?id=35) MacBook Pro 15 A1286 Repair Guide

My screen flickers and goes out sporadically.


Bad video graphics chip on logic board. Probably made by Nvidia. Repair logic board or replace the logic board.

Just been given a apple powerbook 520 to play


wow! That is a museum piece. If it does switch on I would be very surprised if it comes to life. Certainly the battery is likely completely dead. Make sure the computer is plugged into the mains power. I can't remember where the switch was on those, on the back I think. Apple was pretty clever at hiding them, in fact you may have pressed it in your exploration but it just doesn't work. Good luck!

My Macbook pro scree has flickered and gone


It's usually the inverter and not the backlight. You can replace it yourself, it's not that hard.

Fixya.com is a good place to get started. They've got really user friendly guides that will help you from start to finish. Check it out so you know what you're up against.

Otherwise a local Apple tech via craigslist is probably the cheapest route. Or Applecare if that's still a possibility.

Pinstripe cinema display flickers on momentarily then goes black. Image comes back for a split second while when power light glows steadily then goes away while power light flickers. this is a 22"...


when the screen is black and the power light is steadly lit, shine a flash light at the screen. if you can see something, the inverter board is bad and the back light cannot turn on. if the power light flickers, reseat the power plug and put your ear to the back of the monitor where the power plug is. if you hear a buzzing or any high pitched noises; the power supply is bad. use the macufactures warranty for repairs.

Trouble with screen (powerbook G4 15" 1.67 GHz)


Well the issue isn't with the graphic card. It actually is the screen of the PB (PowerBook). I had somewhat of the same issue about 6 months ago on my 17" PB G4. But when it started to do that with mine, the screen would also make sharp vertical lines when opening and/or adjusting angle. So before my Apple Care warranty expired I had the screen fixed FREE. So, if you do have your Apple Care warranty still and not expired, I'd suggest to you to find a Apple Certified computer shop or the nearest Apple store and drop it off with the explanation to have the screen replaced. Otherwise you will have to pay a pretty penny.

And if you do not have the warranty then i suggest you not to take it to a Apple store due to the extreme cost of a new screen on an old machine. Instead goto ifixit.com. This site is great for anyone who has anything portable from Apple (including the non-portable MAC-mini) for replacement or upgrade parts, cheaper and also helps with the install (DIY instructions and pictures to go with it)

Video card


to replace the video card you would have to replace the motherboard it is built into it.before doing so try removing all the ram chips on the underside in a compartment w/4 screws match the ram accordingly(go to best buy or even ebay)
its pc2700 ddr ram and probably pretty cheap right now just buy one stick if that fixes your problem its cheaper than spending 500 or 600 on a board replacement.

Safari Browser makes the 15" PB G4 unusable


I would go info safaRI, and empty cache and reset safari, then go to software update and see if there is an update. I would also check to see if your OSX is up to date. If you are not running 10.4, i would update to at least 10.4.9. If you are running 10.4, i would get a dvd copy of 10.4 and perform what is called an archive and install.

Overheating PowerBook G4 17" 1.67Ghz


If you have AppleCare and your PB is less than 3 yrs old, take it in- that seems abnormal. It's really strange that your PB was heating up while it was shut down. THat indicated that there is s/thing wrong with the shutdown mechanism. Make sure the machine is hsut down before closing the lid. Let it rest a minute.
