MacBook Pro :: Won't Turn On, Sleep Light Blinks Once?
May 13, 2010
I own a MacBook Pro 2.4Ghz and my problem happend like this:Last night I stopped playing SC2 and closed my MBP, then this morning I noticed that while it was closed, it had not gone to sleep mode, or at least that's what I thought, because it was too hot and the fans spinning hard. I openned it and showed no video, but remained on. After a 5-sec power button restart, it flashed the sleep indicator once and did nothing else, except for the HD spinned for a sec.I took the battery off and gave the computer time to cool off, because I sensed it way too hot.After I reinstalled the battery, I was able to turn it on the normal way, it worked just fine, but later I closed it again and when I openned it, it showed no video again.I repeated the process of letting it cool down, but with no effect this time.The sleep indicator turns on once and it does nothing.I tried swapping the memories, resetting the SMC, tried booting pressing control + command + r + p, tried booting without the battery, tried booting without the magsafe, nothing has worked.Now what happens when I press the power button is I hear the HD try to spin for half a second and the sleep indicator turn on once.

my power cord comes unplugged. my battery is 100% charged, and yet whenever the magsafe comes unplugged the whole thing shuts down. I notice the sleep light blinks rapidly a few times then when my cord goes back in things restore? Edit: My macbookpro is a Unibody which is less then 6 months old. I received it as a replacement unit from apple (due to a lemon macbookpro i originally had) Which i figured means that the battery cant be bad, i take extremely good care of my computer.

My imac does not turn on, not even make the noise when booting up. The only sign of life is the blinking light that tells you is on.

I bought a new mpb , i7. a few weeks ago it turned off and it wouldnt turn back on when i connected it to the power source , the sleep light however kept flashing, and it madethis sound like if it was trying to boot. anyway,i left it charging for a bit and it started working on its own.
however, lately its been shutting down when it runs out of battery instead of hibernating (which is really frustrating). and just now its doing the flashing thing again, cept for a much longer time.. any idea how to resolve this/what might be wrong with it?

my Macbook (I believe a 2008 model wouldn't wake up from it's sleep like it does every time I open it (I usually set it to sleep rather than shut it down). I turned it off manually, but when I attempted reboot it does either one of two things:
a) When I simply press the power on button, the screen stays black and the sleep light fades on once, but then fades off and all mechanical sounds abruptly stop.
b) When I press and hold the power button, the sleep light fades on, but then flashes about 10 times rapidly before fading in and once again abruptly turning off.
I have tried this with the charger plugged in several different outlets, not plugged into the Macbook, waiting, removing and putting back the battery. A Google search said it might have something to do with the RAM and pushing it back in, but I have no idea how to do that.

This morning, I synced my iPod with my MacBook and upon completion and permission to disconnect the device, I pulled out the USB cord. At that point the computer instantly turned itself off, and when I hit the power button, I could hear the system trying to start up, but the screen remained black and the sleep light glowed continuously. I unplugged the charger, took out the battery and put it back in, and tried all the troubleshooting tips under the Apple Support guide with no success. I also discovered that when I closed the laptop while it was "on," it would seem to boot up a little more before returning to the black screen. I left it alone for a few hours, and when I tried again to turn it on, it booted up normally and as I was searching for updates, it shut down again as it had earlier.
Does anyone have anything for me to try? I don't want to have to take it into a shop because I can just barely afford to, but I need this computer! Any suggestions would be greatly appreciated :-)

I have a 2 year old macbook that has generally worked well. About 4 days ago, I put it to sleep and didn't touch it again until yesterday so the battery had obviously been drained. I've done this before in the past and whenever I plug the charger back in, the computer starts right up, no problem. This time however, the macbook won't start up, the charger is a solid amber color for about 3 seconds before switching to a blinking green. The screen blinks black (as in I don't even hear the chime and get the gray startup screen) and the little white light in the front blinks quite rapidly. I've tried resetting the PMU several times to no avail. I've taken the ram out and tried each one individually with no changes. I checked the ram carefully as well and they don't seem fried or anything. I've tried plugging the charger in with the battery and without the battery and the result is still the same.
I have another friend here with a macbook so I'm going to test it out with her charger this weekend as well as charge my battery in her laptop and then pop it back into mine and see if it works (although this is really a last ditch attempt on my part).
Any ideas on how to fix it or what the problem is? I don't live in the States so going to a Genius Bar isn't an option.

I recently received a Power Mac G5 from work. They told me I could have it, but reformatting the hard drive and reinstalling the OS was on me. So, I took it home, and plugged it in to turn it on, and the white light on the front blinks 3 times and then stays steady... and then blinks 3 times again... and so on and so on.
The RAM that came with it was bad, so I put in 2, 1 GB PC3200 sticks in it. Isn't it a RAM problem?

I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

The on light at the front of the base (right edge) went out. I have a late 2011 MacBook Pro 13 inch. The apple on the cover side of the monitor still comes on. Oddly enough, this happened right after I installed a trial of Photoshop version 13.0.0 Beta. Should I just have the light replaced or could this be a signal of other problems? I don't have a lot of new stuff installed since I'm coming from a pre intel mac desktop.

I'm only posting this to continue my procrastination of starting homework which is due tomorrow. Ok, so recently I've been asking on these forums how to access my Macbook using my iPod Touch. Being able to fully access my Macbook when I'm 20 miles away at my University is a huge benefit when I realize I forgot an important essay or homework. I discovered I just have to open up port 5900, etc etc, to get into my Macbook from anywhere. It was too much trouble and now I just use [URL] which works as well, though don't think as fast. Well, this works wonders since I've already emailed myself 2 important Keynotes i've create and accessed them from my college and presented them without even having my computer on me.
Well, recently when I get home at night some times it smells strongly of marijuana. Odd since I don't smoke it but my cousin does. He has access to my place and I say he can head over, even if i'm not home and chill, but under any circumstances no smoking. Well, I wanted to use the iSight cam w/ Photo Booth while I'm at the college to see if he indeed was getting high in my living room but before I tested it, I need to get rid of the green light on my Macbook: Getting Rid of The Green Light. Ok, so we're not really turning off the green light here. I looked for hours on how to do this and instead ran into a lot of advice, especially on MacRumors forums, to just white out or tape a small white square over the dot when the green light comes through.
Don't attempt the white out. It'll just go through. As for the white small square...it's completely obvious so don't try that either. Instead, do this:
1. Get a thin card, like a debit card and gently remove the white frame from your macbook. Attached to the back of the frame will be a bunch of these little gray rectangles that hold that frame to the outer part of the macbook. You'll have to take these off gently from the frame and pop them back onto their corresponding places within the Macbook. Easy enough.
2. Then what you do it get a sheet of white paper, cut a super small piece and fold it many times over. Not too thick or the frame won't click back in that area normally.
3. Place it snuggly where the green light turns on and even suggest getting a piece of tape just as small to hold it in place.
4. Turn on Photo booth just to test out if the light goes through. It may but really test it by placing the frame over it, and then seeing if the light goes through.
5. If it doesn't great. Place the frame back on and you're set!

Last week I spilt tea (english tea with soy milk) on it while it was CLOSED, but it got into the side plugs and etc. I turned it off, and put it immediately in rice to dry it out, and later took the battery out as well. I tried to turn it on, but nothing except for a very pale green light coming from the plug itself. After many attemps of turining it on still no success. A roommate opened it up and cleaned the rusty bits with pure alcohol, but still it won't turn on. The rust was only close to the part where the plug goes.Does anyone know if it's just a matter of replacing a piece or something more expensive? I'd like to find out before I go to a repair place.

I recently noticed something rather peculiar about my MacBook. When I put my computer to sleep, the sleep light never does what it used to. As far as I remember, the light is supposed to very bright, then go dim, and then go back to being bright correct? Well, since I installed the latest OS X update, I've noticed that my sleep light never gets dimmer. It just stays on full brightness all the time.

So this morning I woke up and went to press the power button of my Macbook, but nothing happened. I noticed that there is no white IR light and the fan doesn't respond. I checked the battery, it was at full. The power cable was also green when i plugged it into the Macbook. However, it still wouldn't turn on.
Just a general comment, I use the Macbook as a printer server and to browse the internet, so nothing intensive is forced onto the Macbook.So then I tried resetting the SMU, didn't work. I tried turning it on with only battery , and then with only power source, both didn't work either.I have never spilled anything on this macbook, never dropped it, smashed it, or abused it in any way. However, it is 2 years old and I never bought Applecare (Usually, if something is defective, it will show within the first 30 days). I assume it's a logic board failure, and it's going to cost around 700 to fix (which i'd rather just get a new macbook).
I was wondering if anybody know of a reason why the logic board broke, or if there is any remedies that i haven't tried yet?Also, I'm thinking of pawning it off on ebay and then save up and wait for the Macbook Pro refresh. Does anyone have an estimate on how much I can get for a broken Macbook (screen is fine, 4gb of ram (i might replace it w/ 2gb instead) 250 gb HD (might replace with 80gb HD instead), 2.0 ghz c2d (prbly useless cuz the logic board is fried)
