MacBook :: Monitor Turning Itself Off Instantly?
Jan 9, 2011
I've run into a very nasty problem with my macbook (late 2007 normal macbook model I think). Whenever it closes, the monitor goes black. This is normal. What isn't normal is this: whenever I open it and then either start it/awaken it, it gives me the screen... and then the monitor turns the brightness off again! This happens randomly, I have to close and open my screen quite a few times to get it to work-even if I restart the computer. I don't what's causing this, or how to fix it, although I have a hunch that it's the hinge on the back; it started shortly (but not directly) after I replaced my CD drive... I have the tools and instructions needed to open my machine up if it's a fairly simple fix, but I need to know what's going on first.

My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.
Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?

Why is my ADC monitor not turning on after I put my G5 to sleep? I am running an adaptor to my G5 from the ADC monitor (DVI to ADC).The screen usually runs fine when I reset the monitor or turn it off but as for when I put it to sleep, no such luck..This has happened once before and last time I just waited and randomly turned it on a couple days later and boom, the screen booted up.I have tried basic options, like resetting the computer several times, pulling the power cable out of the G5 for several minutes and even a PRAM reset but nothing seems to have made it work as of yet.I assume it's within the G5 as it has happened a few times and the monitor works fine when I test it on other computers..Also as I mentioned before this is not the first time it occured and it just randomly seems to come on whenever.

I have a first gen iMac 24 Intel with a dead logic board. However everything works in it. The screen, power supply, isite, speakers. appear to work fine. I got a MacBook Pro to replace it and I wanted to know if there is a way to turn the old iMac into something that is more like the Apple 24� display, even if I need to do electronics work in it.
I am in IT and have access to a lot of dead stuff I can scavenge for parts. I am also an electronic technician, so I should be able to do this. I just don�t know what I need to do.
Hunting down info on this topic has come with that there are controller issues. If I can pull a controller out of another dead LCD display that I happen to have, I can see it working. I can even see the possibility of adding the electronics from a USB hub to pipe USB functions over a DVI cable. And get the iSite and speakers working.

As the title asks, really. Is it safer for an iMac to be shut down from a power cut whilst turned on, or whilst sleeping? We tend to get a power cut once every couple of months.

I've never owned an imac since I don't care for the AIO concept due to the fact that when your computer becomes obsolete, you lose the monitor as well, without any good reason. I really need a new computer, and as usual I'm thinking about the mini. The problem is that they are really slow and I need the hardware of the imac. I figured that buying an AIO, isn't that bad if you can still use the monitor even when the computer's hardware is obsolete. I've summed it up to a couple of questions:
1. Can you use the imac as a monitor for another computer without turning the enitre hardware on? Perhaps you can easily mod it, so that the monitor is the only thing working.
2. As a follow-up question, if something goes wrong with the imac, that isn't related to the monitor directly (i.e cpu, ram, hdd, etc..), could you still use it as a monitor for another computer?
If the answers to those questions are positive, I'll probably get a 27" imac.

i have 2 LCD's hooked to the new Mini as such:
1 going mini display port to DVI adapter to DVI on 19" Monitor (standard monitor)
1 going mini DVI to DVI adapter to a DVI to HDMI on 52" LCD (Samsung TV)
i just sold me iMac and switched to the Mini not only to be able to hide the Mini which i couldn't do with the iMac but also when i watch a movie full screen on the 52 i was never able to turn off the iMac monitor and would have to cover it with a towel so that it was dark in the room except for the 52 showing the movie.
my thought was that with 2 monitors separately hooked up to the Mini that i could solve the turning off the second monitor problem as they would now both have power buttons. besides making it dark in the room i also like to have the monitor off and so that i can have Plex on the 52 always in full screen mode so my wife can just hit "Watch Plex" on the logitech remote and the TV and Stereo switch to the proper inputs and away she goes to watch whatever without having to touch the computer which when both monitors are on works perfectly.

I have a 5-year-old PowerBook G4. I remember I changed the battery about a year or two ago, because when I used to take it to classes in college, and use it unplugged, my laptop would shut off in less than an hour (more like ~30 min) when it reaches ~30%. After I got a new battery, it went back to normal, and lasted much longer. In the past couple of days, I noticed that within about 5-10 minutes of using my PB unplugged, battery goes from 100% --> ~85%, and then all of a sudden shuts down.
When I plug it back in to a power supply, and it starts back up, it starts recharging from 0%... this seems a little extreme. I haven't noticed this problem because I almost have it plugged in these days, as I usually use it at home or at work where I have a power supply available, and I use it for a few hour period at a time. Does this seem purely like a battery problem?! (ie. it's just time for a new battery...)

I am having problem to eject an external flash drive in my MacBook. After I eject the disk, the icon disappears normally, but re-appears instantly before I plug it out from the USB hub. So, every time I end up with an irritating warning sign.
Is there a way to stop remounting a disk once it is ejected from the system?
The flash drive I am having problem is actually not a generic flash drive but a mp3 player manufactured by Iriver - Iriver T5, which also work as a flash drive for me and a cross-plateform disk space for use in emergency.
I do not have this problem with other dedicated flash and external drivers.
Please share if you have any solution or thoughts toward the solutions.

Hopefully this isn't a duplicate thread....
After a week of owning this great computer I closed the lid to put it to sleep last night (same as i do every night) and the sleep indicator light dimmed as it would when it goes to sleep. I heard the HD and fan turn off as normal. But as soon as the front light dimmed all the way the apple icon flashed for a split second and the HD started back up and the sleep indicator light stayed brightly lit for about 10-15 seconds. It would then dim again as if it was going to sleep and start this cycle all over again. I didn't realize this until i was laying in bed and heard my HD start up every few seconds.
I tried restarting the computer and nothing changed. Nothing is running in my dock except for finder. I tried putting it to sleep with the lid open and it went to sleep, but then just came back awake within a few seconds. I went to click shutdown and it restarted. I tried to shutdown once more and it just restarted. I did a hard shutdown and then turned it on and tried to put it to sleep and it still was the same....
I'm new to mac so I'm very naive with these still.
Edit: I'd also like to add that my computer now gets very very very hot on the bottom with nothing running. Not nearly as hot as a few days ago. I don't know if it's related.

So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?

Just on a curious thought, anybody's MBPs experiencing heat issues that cause the fans to kick in so much that they power off instantly? And another question, if you do feel heat, where is it the most intense?

I do not have AppleCare on this machine. I've got a 27" iMac that will randomly shut down, be it in the middle of playing music on iTunes, while I'm typing a document or while the machine is simply in screensaver mode doing nothing. Usually the machine tries to instantly reboot itself. All too often, it cannot be rebooted and I have to let sit for quite sometime before it will even power back on. Lately the problem has gotten worse, almost never reboots by itself.
Finally, in the last few days, it just won't turn back on. Nothing. My biggest concern is that I have an unreleased music album from an instantly recognizable major client on the iMac's hard drive, not due out for many more months and still unannounced. I can't simply take the computer into an Apple store for troubleshooting as those files are worth and could cost me exponentially more than even a new iMac outright ever would.

I recently purchased an iBook used from someone locally. I got a good price because he said the battery was weak. However, I want to make sure that's actually the case. The power cord connection is not loose.
Coconutbattery says my battery is 36% health, but it also says it's not plugged into the charger when it actually is, so I don't know how reliable this program is. It says my mac is 27 months old, i have 367 cycles on the battery... etc. And I am running Tiger.
The problem is that the power meter on the top bar will say i've got a full charge... so I run the computer (on battery) down to about 60% according to the meter, but the computer instantly shuts off. I try to reboot, and it shuts off while rebooting. It's like the battery works fine and suddenly dies. I get about 30-40 minutes use out of the battery.
Is this the battery or do I have other problems? This only happens when using the battery.

I just downloaded Safari 4 beta from the apple site, installed it, restarted etc and everytime I launch it it crashes instantly. So, I uninstalled it (using the uninstaller), restarted, installed it, restarted again and still have the same problem. I've turned Growl off because I've heard this causes issues with some applications.

While working on my iMac, it suddenly went off. No warning at all. I've tried all the basic stuff and nothing happens. Holding the power button in and I don't hear the normal sounds. Thought it might have overheated but after it's cooled down, still nothing.

Every 2-20 minutes, my iMac is dropping, then instantly resetting my wifi connection. The actual wifi drop lasts no longer than 5 seconds, and instantly reconnects itself with no input from me... the problem is it completely interrupts any downloading, streaming, gaming, or anything else I might be doing that requires a constant internet connection. It seems to drop off just long enough to stop the connection, then it resets all on it's own.
I'm currently using a mid-2011 27 inch iMac intel core i5 3.1 ghz processor w/ OS X Lion 10.7.3. I have a Linksys router and a GCI issued modem, unsure of the brand as there are minimal markings on it. The internet/tv service (run by GCI) is smooth throughout the rest of my home, and no other items we own connected to the net seem to have the same problem...
I have tried soft resets on both the modem and router. I have restarted my machine several times and re-added the network location and wifi connection to my computer. I have unplugged both modem and router to let those reset and have unplugged and reconnected my coax cable for several minutes as well. No time of day seems to work well, and it's becoming quite difficult to work and do other fun functions like stream television or game

About a month ago Netflix started giving me problems while watching instantly. Audio wasn't syncing with video and it would skip and freeze. I tried uninstalling and reinstalling Silverlight, but that didn't work. After corresponding via email with micrsoft silverlight support and a complete uninstall and reinstall of silverlight and testing it on other websites, we determined that silverlight is not the issue. I then tried Netflix support, which was terrible and of no help at all. Now Netflix crashes all browser (Safari, Firefox, & Chrome) upon loading. Netflix streaming works fine on all other computers in the house. I have all of the most recent updates of all browsers, I've tried repairing disk permissions and I'm running OS X 10.6.8 with all current software updates. I'm not sure what else to do.

Just recently (this night,) whenever I would unplug my main USB hub, my iMac (Late 2006) would turn off (that is, instantly shut down as if the power had been disconnected). I don't know why this happened, but it turned on immediately afterward so I shrugged it off. The last time this happened, (the 4th time,) the iMac wouldn't turn back on at all.
It responds to power button presses, and you can hear the harddrive spinning up and the CD drive whirring and fans spinning. The sleep light in front stays on, but the display stays black, and it doesn't make the characteristic chime when it "turns on". In addition, it doesn't seem to be delivering power to USB devices, so there's no way that I can boot up from a startup disc or anything to see what's going on.
What do you guys think could be wrong with my computer? I doubt my non-existant applecare would cover anything of this sort, and I'm pretty sure that i'm SOL for hopes of a computer that just works. In addition, one other question. I was working on a VERY important school assignment at the time, (cliche, I know,) so is there any way I can connect another computer to my iMac so I can get my school assignment off of it?
