MacBook Pro :: Not Booting Properly - "need To Restart Computer - Hold Down Power Button"
May 23, 2010
My Macbook pro is not booting properly. When I start it up, it goes through the normal process and gets to a point where a screen comes up telling me: "You need to restart your computer. Hold down the Power button for several seconds or press restart now" This happens every time. I tried to start in safe mode and holding down the option key and selecting the mac partition. Neither would work.
Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was: 1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up. 2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does). 3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...) 4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart. 5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.
Whenever I open my mac mini it comes up with the same message "You need to restart your computer hold down the power button or press restart" in four different languages.
I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.
Sometime when I stop using my MBP for a minute or so, the screen goes black and won't wake up. I can see that the lights are on the keyboard and it's running but won't wake up. I will have to hold the power button down and then restart. Does any one know how to fix this? It's starting to do it more and more ofter.
So I'm having issues with the computer not waking up in the morning. I guess it goes into a deep sleep of some sort and I have to hold the power button twice to turn it on, and get greeted with a computer experienced a problem message on login.Â
The most recent log in the system diagnostics is titled:
I have a macbook pro, bought it May last year(2008). I don't know much about computers, but I loved the transition between pc and mac, had no trouble with it, loved to work with it, until now. I had noticed it became slower like 3 weeks ago, and a week ago, it started to freeze up on me followed by a message that said please restart your computer by pressing the power button and the screen becomes dark. When I try to restart it again, it takes a while because it shuts down again and again, until the 10th time it works. The store told me to clean intall, which I did yesterday, it seemed to have worked, it was faster for sure, but today it happened again, 3 times! Has this happened to anyone? Does somebody know what to do?
My 15" early 2008 MacBook Pro won't shut down unless I hold the power button. I have done extensive searches and have done the following and the problem still persists. I have pulled the battery to reset the SMC or whatever it is called. I ran disk utilities and repaired the permissions. I deleted unnecessary files in the preferences folder...... still no go..... in fact it won't load software updates because it gets hung up.... then I have to force quit it by holding the power button..... I am at a loss.
I have got the message "You need to restart your computer. Hold down..." in my MBA. Having read what have been posted before about this problem, I do not find a proper solution for it. So I have just copied the message I get from the screen after a safe boot op. It says
I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

I just got my MBP logic board replaced by Apple, and now it works fine, but when I press the power button, my computer freezes and this happens:
I'm probably bringing it to an Apple certified repair center, but I don't trust them as much as I do the Genius Bar, plus I'm pretty good at DIY stuff, so is it possible to fix this by myself?
my dual 2.3 ghz G5 power mac with 3.5 gig memory running 10.4.11 started crashing (grey screen "you must restart your computer...) and soon stopped booting. suspecting the hard drive as it had been noisy for some time I ran "repair disk" in disk utility from my mac book (connected by firewire, G5 booted as target) and it booted again but soon crashed again and after a couple more crashes it would not boot and attempts to repair failed. I installed a brand new hard drive, installed osx 10.5 and updated it to 10.5.8 and it seemed to install and boot fine but while trying to burn a .dmg dvd with toast (10.0.5) I got the grey screen anain and repeated attempts to burn a disc with the same .dmg resulted in a crash every time. it has also crashed while downloading, playing back itunes hd video, and using an "eye tv hybrid" tv tuner as a dvr. below is the most recent crash log - note that most of them have referenced cpu 0 although the most recent it's cpu 1 -THANX & PLEASE HELPInterval Since Last Panic Report: 0 sec Panics Since Last Report: Anonymous 4A58CF1E-844-409F-8BF3-65A3A3CD2E79.......
I have brought the 21,5" iMac 1 week ago. I just chosed the preconfigured model. But i have had some problems with it.When the computer has been to sleep for some hours, it wont wake up with click on keyboard or on the mouse. I will have to use the powerbutton, where the computer then comes with a error, but it starts up.
Out of the blue I keep getting a kernel panic (You must restart computer) while using my G4. All I use it for is word processing and internet browsing. Seems to happen when switching between windows.Here is my most recent crash log reports:Â
Mon Mar 26 21:27:00 2012Â Â Unresolved kernel trap(cpu 0): 0x300 - Data access DAR=0x000000002B154200 PC=0x00000000000ACD04 Latest crash info for cpu 0: Exception state (sv=0x2708C280)
I've been using macs all my life but have never run into this problem. My ibook g4 just recently going crazy on me. I had it running then this dialog box came up with the power symbol in it saying i needed to restart my computer so i did as it said.
After it chimed letting me kno it restarted the gray screen came up and i had the ? folder pop up. So i looked around online and the majority said it was my hard drive. My computer also had a bad battery it wouldn't hold a charge and the ibook itself had to be plugged in at all times. My ac charger pin broke (the part that goes into the computer) so i bought a new one a 45w but just recently finding out i need a 65w! But finally my computer does not turn on at all now. Before i go and buy a new hard drive and battery and charger.
So i pull the plug and wait 30 seconds and the light is still on when i put the plug back in. when i hold the force quit button. Nothing happens. the light just stays on.
I went on vacation to Florida this week, I come back, start up my iMac, plug my headphones in, only to hear audio to come out of my iMac's speakers. I called apple, and I did the whole restart and hold down command, option, P and R and still nothing, I have apple care and he said I should talk to small dog. I called Small Dog gave them a description and said they would have to send it to apple because my logic board might have issues. My question is this
I want to know how to find out what is the max amount of ram my computer can actually take advantage of, rather than tell you my model and you tell me what is the max because I know it varies according to the model of the Computer Â
here is my model: Macbook(13-inch, Mid 2010 [unibody]) basically the latest version of the white macbook.
im new here and im a little unsure where to post about my macbook, But i hope this is the place. Anyways, i was wondering if its possible to toggle the fn button, cause im a flash animator, and its pretty anoying that i have to hold fn down to create a new keyframe.
I have an old Performa 6400/180, which has been working fine up until a few days ago. Then one day I booted the machine up and was greeted by the following "bomb" message:
"Sorry, a system error occurred.
bus error To temporarily turn off extensions, restart and hold down the shift key."
I have followed these instructions, but it only gets to the "Starting Up. . ." screen and hangs while searching for extensions.
I can't find the documentation that has the OS version, but the machine was bought with whatever was current in early 1996 and has not been updated since.
basically i havent had my macbook air that long (few month, maybe few more) but all of a sudden the click button on the trackpad has almost became slightly annoying, that when you press it slightly it clicks in as if youve clicked but nothing has happened, and then i press a slight bit more (normal pressure for a click) and it works normal. its just really annoying and it seems to be getting worse at one end, and ideally id like it to stop.
During start up I get the apple logo and everything boots although it takes forever, the apple logo goes away screen goes blue, and sometimes it loads to the login screen about 10 mins later, and sometimes it just sits there. - During restart, it shuts down makes all the appropriate sounds, screen goes dark, and all you hear is a residual humming from the inside under the keyboard, and then never restarts. (You have to force shutdown) - Same story as above with both shutdown, and sleep.
The only way to get it to load successfully is in safe mode, but even then it still wont do the above problem correctly, it just at least starts.
- Resetting the PRAM, Holding power button for 5 seconds until repeating flashes, I've tried reinstalling snow leopard 5 times, I've checked for updates, I've repaired disk permissions, I've repaired the disk, I've even tried stepping the OSX back down to 10.3(The original operating software for this MB)
I have a late 2008 uMBP 15 inch and in safari, regardless of using the integrated graphics card or the higher end card, when I press apple t for a new tab the computer hangs for at least 10 seconds then once it finally loads the top sites page it appears all scrambles for a second, then it works normally.
My second problem is that my hinge is very loose. I can't hold the laptop at 45 degree angle without the screen falling down and closing. Will apple fix this?
