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.

PowerPC :: G4 Not Booting - Hold Power Button And Restart Computer

Jun 3, 2009

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.

Mac Mini :: Restart Message - Hold Power Button / Press Restart Button

Apr 29, 2009

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.

OS X :: Macbook Pro Freezes With Msg Restart Computer By Pressing Power Button

Apr 8, 2009

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?

MacBook Pro :: Won't Shut Down Unless Hold Power Button

Jun 17, 2009

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.

MacBook Pro :: Computer Freezes After I Press The Power Button?

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.......

PowerPC :: Dialog Box Came Up With Power Symbol - Saying Needed To Restart My Computer

Mar 4, 2009

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.

Software :: Macintosh Performa Not Starting Up - Restart And Hold Down The Shift Key

Feb 18, 2009

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.

MacBook :: Won't Shutdown / Restart / Sleep Or Startup Properly

May 6, 2010

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)

MacBook Pro :: Computer Hangs When Press Apple+t / Hinge Can't Hold Laptop At 45 Degree

May 2, 2010

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?
