Mac Pro :: Blinking Front Panel Light
Dec 14, 2009
I shall describe the sequence of events as accurately as i can.
1) I havent used my mac pro for a couple of weeks
2) I switch it on 5 mins ago and it boots fine, I log in and launch safari from the dock.
3) Computer freezes, mouse doesn't move, complete unresponsive.
4) I push power button for a few seconds to force a shut down.
5) I power up.
6) boots fine, after surfing the web for a few mins, MP just reboots, no warning, screen just goes black and the fans and chime kick in.
7) doesn't get to log in screen, instead it reboots itself, fans and chimes kick in
8) doesn't like it, computer shuts down, front panel light blinking at 1/2 second intervals.

If anybody here has a camcorder with a Firewire output, can you check something for me? I'm trying to use the front panel FW port on my new Mac Pro and it doesn't see my camcorder (Canon GL2) when I plug it in to capture footage. It IS seen if I plug the same FW cable into the port on the back of the ACD so that seems to rule out a bad FW cable. Also, the port seems to be working because it will see a FW CF cardreader when I insert it into the port. Any ideas? Is there a difference between the front and rear FW ports on the latest Mac Pro?

Is it possible to reassign the front panel 3.5mm jack to mic in?
I'd like to connect a headset (mic + headphones) to be able to talk on Skype, but unfortunately there is no normal mic in just like on all Macs. I bought a cheap jack-to-USB converter (basically, small USB soundcard) on eBay but the sound is a little noisy when I use it.

I have the older MacBook Pro with the sleep light on the front button that attaches the screen to the main computer. I noticed that the light no longer blinks when it is on sleep. I recently upgraded my internal HD and have no idea if that could have caused it or not. I guess, since my Mac is three years old, there is also the possibility that the light just got old and went out.

I've been having some issues with one of my Airport Express units, the one the modem's connected to. I've been on the phone with Apple a few times, and have had my MacBook (brand new) checked out for antenna issues by a Genius. All is well. I've tried resets of all sorts on the Express, and what happens is that in the mornings the main Express is blinking yellow. This morning nothing--not any kind of reset--would change that. is it time for a new Express?

I usually don't complain about stuff but I noticed last night on my MBP (one below) that I have some light leakage on the left and right side of the panel. When I have a dark wallpaper you can defiantly notice it.

I'm a relatively new Mac user. In fact, I haven't had that much experience at all. I work in a donations store and today we got a donation of an iMac. I searched around a bit and I'm sure it's a G5 model. It looks like [URL]. It looks to be in great condition, no scratches, not even a fingerprint on the monitor.
However, when I turned it on, after plugging the power chord in, I started experiencing problems. The fans kicked on and I heard the chime (I assume that was a post?) but I was getting no video and the white LED on the front of the screen was flashing on and off. The exact pattern is strange - I don't think I've see it before. It flashes once, then stops, then flashes again, then stops. Over and over. No sequence. :| The computer did not come with a keyboard or a mouse. I was testing it to see if it actually worked, before I bought the keyboard and the mouse, so I'm wondering if it has something to do with that? I'm not really sure.

I have the new 2.4 GHz MacBook model since last Thursday, and something throws me off a little bit.
When I close the lid, putting the MacBook to sleep, I can still hear the inner workings (fan, maybe hdd) of the laptop for a while. And the light doesn't blink softly and slow like it did on the iBook.
As I come from the iBook, I was used to wait one to ten seconds to get it to sleep after the lid was closed, and the blinking light showed me it was asleep. But the MacBook's doesn't.
Is that normal?
PS: I made two tests. It took 28 seconds until the light started pulsing, shortly after the fan stopped spinning and the hard drive reading/writing head (?) stopped in its safe position.

I was trying to set up my airport extreme with my internet when I couldn't get anywhere because of the blinking yellow light. I have a 2wire at&t router that i connected with to the airport extreme via ethernet(the port in the back has a green light btw). I tried scanning for the airport extreme with airport utility but it couldn't find anything.

I have a macbook pro 13" and I'm running on Snow Leopard Mac OS X 10.6.6. What happened is that I close the laptop while it was turned on. After a while I opened it and the screen wouldn't turn on. Other thing I noticed was that the sleep light was also turned off, instead of blinking.

I had modem/router, which I got from the phone company here. It wasn't working that great, so I decided to order a Netgear modem and an Apple Airport Extreme. I got the Netgear modem to get me on the web, and the ethernet connection light stayed on, but when I connect it to my AE, that ethernet light goes off and the AE is constantly blinking. I reset the modem, and still nothing. I then reset the AE, and still the same thing. And when I try to connect my MB and iMac wirelessly to the AE, it tells me there are no apple devices present, and to retry.

I've noticed that my caps lock light keeps blinking randomly. It usually happens in groups of blinks every 5 minutes or so. It started doing this after I upgraded to snow leopard. Why is it doing this?

I put my MacBook on charge but nothing happened there was no orange or green light and in the top right hand corner it said 'not charging' . I tried it a few more times and then the led just flicked from green to orange so I shut the mac down just before it ran out of battery. I then borrowed my friends macbok charger the same power as my other one but now the led just flashes orange and as it mac won't turn on I guess it's not charging it properly.

Just kinda notice there's a red light visible through the front mesh, on opening the side door, the light seems to be coming from one of the four LED's on the lower memory riser. On closer inspection, the label says DIMM 2.
I've tried swapping, moved some ram about.. and the light still appears (on the same riser). Does this mean that riser has developed a fault?

I have a Mac Mini from 2009. And it stands in my bedroom and is almost always on. So the led light is a bit annoying in front of the Mac Mini. Is there a way to turn this off when it's on?

I've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.

A few hours ago my MBP (15" from January 2011) had almost no battery, so I plugged in the charger - but nothing happened. No green or orange light - or indicator on finder. I went to System Information which confirmed that it had 0% battery left and it wasn't charging, even with the MagSafe correctly plugged in.
I checked the wall connector and it's functioning well on other devices. The battery eventually died and now my macbook won't turn on. The light on the adapter and on the side of the notebook flashes green inconsistently. It won't turn on since it has no battery. I've tried reseting the SMC but nothing happend.

Tonight I came into my office and my PowerBook was sleeping. I have an external display and I usually turn my display on and wiggle the mouse (after I turn that on) and nothing happened. I looked and my display was still in standby mode, my wacom and eye tv had the same behavior. The powerbook light stopped blinking (I heard the drive wake) and then nothing. Nothing happened still. I opened the lid, hit the power button and still nothing. Held it down, and nothing. I ended up having to take the battery out and then I started the machine. Since then I've rebooted twice just for fun and since then the below screenshot shows that the "Jessica's Computer" window keeps popping up.
Two questions:
#1 What could have happened or what does it mean when the powerbook is sleeping, then wakes but never really wakes and just shuts off?
#2 What is up with that window opening as though this is some sort of start up program you'd find in windows?
Specs: Powerbook 1.67 ghz second to last rev...rev D I think. 1.5 gig ram. os 10.4.7

I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?

My Apple remote won't pair with my iMac (Lion) or my MacBook Pro (Snow Leopard). It works with iTunes and VLC Media Player on both without being paired, but pairing is supposed to work isn't it?I've used the iMac's camera to check that the remote's battery is OK. When I press any one button, the live camera picture shows a blinking light. However, if I press two buttons (Menu and Next, as is required for pairing) there is no blinking light.Is it possible that the Apple remote's battery is good enough to create a blinking light when one button is pressed, but not when two are pressed? I've hardly used it, so I'd be surprised if the battery was low already.
Also, I'm not sure that when I click on Pair... in System Preferences > Security & Privacy, whether the pressing of two buttons for pairing has to be done while the OK popup is present or not. It doesn't matter when I try it, I never see a paired-remote graphic.

What do I do if the front camera on my MacBook Pro does not work, but the green light next to the camera is on? I've tried use photo booth, facetime, skype to test the camera, the green light was on, but there is no image. It means my front camera's gone?
