When shutting down, we get a familiar light blue screen before the computer turns off. I'm getting this flashing at me while operating my MBP. It seems to happen twice, every so often. The screen will turn blue and become empty simultaneously for about a half second - then the screen I'm expecting to see comes back for about half a second - and then the light blue screen comes back again for about a half a second, and then everything goes back to normal.What the heck is this?
I must say, I'm having a little bit of a difficult time with my switch to Apple from Microsoft last November. I've already had to replace the logic board, it appears as if my network card is no longer working (I can only connect via WiFi) - and now I'm having this odd light-blue screen flashing... My video card?
My 2010 13" Pro seems to have some blue/magenta light leaking from the bottom of the screen. This is only visible with the brightness turned up and against a black background (i.e. when watching a letterbox movie). It's quite different from the "typical" white light leak that I've witnessed on other lcds. Would this be "normal"?
Also - and this may seem like nit-picking - but my caps lock key feels a bit flimsier than the rest of the keys. Again - is this "normal"?
I installed several system updates on my 2007 iMac last night, running OS 10.7, and today I can only get a black screen with a flashing white power light when I try to start up. My computer will neither start up nor completely shut down, and my wired keyboard won't communicate either.
i just upgraded my ibook g3 hd to 20gb. i put in my tiger install disc 1 and i let it go while i was out of the room. i heard the startup chime from another room, later i went to see it with a blue screen and mouse cursor. it wouldn't do anything. then i restarted it with the install disc again, holding C down, and it booted to a grey screen which after about a minute went to the flashing folder with the ? mark.
my G5 (10.5.4)in work has some HD errors (From the Disk utility program) that need to be resolved by restarting with the os CD. But The OSX Disc will not load i just get a light blue screen. Is there anyway i can fix these problems?
I have a 2.0 GHz early 2005 Power Mac G5 (7,3) that won't get past the light blue screen at start-up. I've tried everything - reset the PRAM, Apple Hardware Check (on overnight loops, everything came back OK), fsck (all OK), repaired my HD and permissions on it, and then erased the drive using Target Disk Mode and another Mac, and attempted to reinstall OSX from the install disk that came with it (with OSX Tiger). I've tried switching out the RAM with no luck.
The only thing I haven't tried is a new video card (the installed one is an ATI Radeon 9600). Here's what it does: powers on with the usual chime, then moves on to the white Apple screen, the wheel spins, then it moves on to a darker blue screen, then it finally moves on to a lighter blue screen with an arrow, and it just stays there. It will boot into safe mode (pressing shift), but I can't even upgrade to Leopard in safe mode, much less figure out what's wrong.
so i go to turn my imac on tonight and it makes the normal noise when it always turns on but the screen stays blank(light blue)....after about 2 minutes this little picture of a folder with a question mark shows up in the middle of the screen. it keeps making this clicking noise as well. ive tried unplugging everything and restarting it here is a pic of what the thing that pop ups looks like [URL]
My wife's MacBook Pro has failed to start. Strangely the button to open the lid on front flashes.The computer recently had a new mother board put in. Feburary. Bit of a waste of money on and old mac. But there you go.Now we can't get it to turn on.Disk drive macs a sound but screen doesn't even turn grey.Can't seem to reset PRAM. Get no chimes at all.
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?
I have not used my MacBook for a couple of days n today realised it needed charging when I come to use it so I plugged it in. I get a green flashing light but it won't charge? I have only had it since April so can't see it being the mac is it the charger itself?
I have an old macbookpro which doesn't have a good battery. last night it shut off because I didn't have the power chord attached. now I can't power it up. the light on the power chord flashes (slowly) between red and green.
New mac user. Got a macbook pro model a1278. When it is plugged in the charger flashes orange faintly. Tried resetting the smc but nothing. Any ideas? Hard drive might be bad but other than that im not sure.a bad hard drive would cause this.
I have iMac 27 and screen problem on start up i have blue vertical lines, when it start i have a lot of blue dots and nothing else. when I connect outside monitor its showing the same.
Just installed lion and still the same problem when it starts blue dots, when startup in safe mode loads of blue lines and dots on the screen.
while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.
My PPC G5 Mac Power Pro has been working fine, on one startup recently the screen didn't come on, the keyboard and mouse did not pass the startup test and the white light flashes three times. After a while the fans go into hovercraft mode! I've reseated the RAm and checked all other cards.
This morning my girlfriend booted up the MP and it froze when she tried to log on. A short time after freezing she was able to bring up the Dashboard but then the computer display went wild flashing like a strobe light. Ever heard of this?
Iit doesn't seem to affect performance but it's still puzzling me. Since I bought my Time Capsule several months ago the light on the front often switches from green to flashing orange after a few days of operation. Doing a hard reboot of the Time Capsule fixes the problem but then again after a few days it will be flashing orange again. A flashing orange light is supposed to indicate some kind of problem but I'm not noticing any change in network performance or functionality at all.
I just received a 2 TB TC (part no. MC344LL/A) which I am trying to connect to an existing network. I have an iMac (24", 2.93 GHz, 4 GB ram) and a Belking54g router. I tried connecting the TC directly to the modem (Time Warner Cable) and the airport utility recognized the TC, but when it updates it, the connection gets lost and it can no longer find the TC. TC goes into flashing orange mode and nothing happens until I hard reset the router (by pressing the button in the rear using a pen).
I have an iMac G5 iSight. When the power button is pressed there is no sound and a white light flashes, but nothing else happens. I tried the power reset method and replaced the power supply, but the same thing happens. The white light just keeps flashing.
My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.
