MacBook Pro :: Only Powers On When Upside And Almost Closed
Nov 3, 2010
I have an older MBP (1.83 Intel Core Duo) When I push the power button, I hear a little electric noise, then a fizzle noise. It won't turn on. However, if I close it almost all the way and turn it upside down, it powers up fine. Once it's running, no issues. Any idea where to start with trying to correct this problem? I don't know what part could be making this happen. And yes, it has to be both upside down and almost totally closed.
Does anyone know if there would be an issue if I play a DVD on an upside down MacBook? I plan to mount the MacBook upside down under the kitchen cabinet to watch videos while doing kitchen work.
I have a 2009 macbook pro unibody, I just replaced the battery but my macbook pro 2009 powers off unexpectedly. Sometimes while its plugged in and other times when running on the battery, when it gets to 67% life left it powers down. What is causing this and how can I fix it. I have already had a brand new battery put in it. I am running Mavericks OS currently.
I have a recently-purchased MBP Retina 15 inch from Mid 2012.
Every time that I put my laptop laptop to sleep while it is on battery, it sleeps fine for about an hour. After an hour or so, I hear the boot sound come from the laptop. When I open the screen at that point, the laptop is powered off. I have to power up the laptop. The laptop is not in hibernate mode, but has actually shut down (pressing other keys on the keyboard doesn't wake it up, I have to use the power button).
Applications start back up when I log in, however for example VMWare has rudely powered off (so I lose the state of my virtual machines), and any terminal programs that I was running (even if I just had a document open in 'vi') are also terminated.
I wonder, what causes this behavior? Is my system defective in some way, or is there an OS tweak in Mavericks to stop the computer from rudely powering off/force quitting all open apps in the process?
I've read that OS X now likes to hibernate laptops after an hour, but clearly hibernation isn't what's happening here.
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
I have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?

My early 09 MBP just started having trouble with the USB port closest to the audio in/out. That port powers on my USB gadget, but it doesn't work. i.e. my mighty mouses laser turns on, but doesn't work. Anyone else having trouble with this?
I am wondering that is it essential to connect power adaptor all the time while operating in closed calmshell mode? When I unpluged the cable it didn't work. Is there some way?
Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
I'm working on a modding project, and due to the constraints of the lcd wiring in my old ibook, I need to mount the screen upside down. Is there a way in OSX to flip the screen so that it projects upside down?
I have a macbook pro 15 inch running windows 7 32-bit. It was running fine for a while but then the screen wouldn't turn on after it went to sleep. I took it to the Apple Store to find out that the Logic Board was broken. They took it and they mailed it back to me about 2-3 days later. Now in Mac or Windows mode, the camera is upside-down. Is there anything i can do?
I the new iTunes all my songs on each album are in the opposide order of the actual album: so each time i play the album it starts from the last song to the first one...how can i make this stop?
I have an '07 vintage (DVI) Mac Mini I use as a media center. I haven't used it in a few months & its been shut down during that time. I went to start it up today & the power light went on & I could hear the fan start up but no start-up chime & no video.
I did an PMU reset to no avail. I'm thinking the logic board is done (it's under warranty & I have an appt. with a "genius" tomorrow). Just wondering if there is anything else I should try before I bring it in.
My Mini powers itself down before it finishes booting.
It's a 1.25Ghz G4 Mini, so it's a few years old. As of the last few days the computer turns itself off. So I push the power button and I get as far as the grey screen and I see the circle logo rotate and I can hear the disk heads seeking if I place my ear near the Mini. But before the OS boots, while the screen is still grey the Mini powers off. It does this with the recovery DVD in the drive too. Either way it never boots
Lately i've been coming home to find my imac on. I've been shutting it down due to all the thunderstorms in my area. Under the energy saver options, wake for ethernet... isn't checked off. I do run eye tv but i dont have anything scheduled. Is there anything else i should check? I have an external hard drive and printer connected to the usb ports. It's an intel imac, 5 months old, 1 gig of ram and running the latest version of leopard.
After a forced power down my iMAC won't boot again.
The machine simply powers off after the spinning gear on the gray start up screen spins for a few seconds.
I've tried booting in safe mode, doing a PRAM reset and inserting the Installer DVD but I don't even get to any of these steps and the machine turns off.
Problem: powers up, will not complete start up sequence What led to the problem: Ignorance, mostly. CD was stuck in vertical bay and I tried someone's suggestion to eject via terminal. If you are laughing (and/or groaning), you know what must have happened. Here are steps taken to rectify disk eject and start up problems, with the results. Note: iMac install disk one remains in the vertical bay, unable to be read or ejected. applejack, fsck -fy ... multiple times. Results: disk & permissions repaired and/or verified but OSX still will not start up. It starts with grey screen, goes to blue with grey window. Progress bar moves slowly from left to right and seems to reach 100%. Operation stalls at that point. Note: Any attempt to use diskutil stalls and commands such as list, mount do not execute. drutil eject gave these results: dyld library not loaded: /system/library/Frameworks/OpenGL.framework/versions/A/openGL referenced from: /system/library/frameworks/QuartzCore.framework/versions/A/Quartzcore reason: image not foundTrace/BPT trap
My first mini has a problem. It will power on with the light and then promptly turn off in about 3 seconds. The hard drive spins up but the fan does not turn on. No image on the screen or anything. the mini is open for diagnosis and will do the same thing if the CPU is not installed. Interesting question what will a mini do when it is powered on but doesn't have its CPU installed?
My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.
I have a Macbook pro and was running windows through bootcamp. When opening windows the display is upside down and is staying that way. Have tried to reboot with no luck.
With external monitor attached, Macbook goes into sleep mode when I close the lid, even when its AC attached. Any idea how to disable that so I can run with lid closed on VGA monitor?
I have a late 2008 unibody macbook connected to a brand new Samsung monitor via a displayport to DVI cable and everything works great until I shut my macbook. The external monitor continues to work fine but my wireless seems to lose connection, my desk is approximately 15 feet from a wireless repeater and Airport appears to have a full signal but it will act as if there is a bad connection until I open my macbook back up and then the internet works fine.
I was talking to a friend and he mentioned that some displayport to DVI cables do not have sufficient shielding therefore interfering with the wireless signal but if that was the issue it should be effecting the wireless signal at all times, not just when the macbook is closed.
On every MB I've used since they first came out, you could hook the audio and video up, close the lid, and if it went into sleep mode, the Apple Remote would trigger a "wake up" for mediacenter purposes on a TV/stereo. My SR MB w/ 10.5 doesn't do it. As soon as the lid closes, it's asleep no matter how I toggle the view between screen and external port. Front Row doesn't wake it anymore. Anyone else having this problem? I wanted to find out before calling and asking.
I am using my MacBook with the lid closed, mainly as a desktop. I plan to run Handbrake to rip DVDs. It takes hours and fan is on constantly. Will the heat dissipate better with the lid closed or open? The vent seems to be on the back and I can feel the heat venting out with the lid closed.
