Power Mac G5 :: Dual 1.8 Not Booting When Pressing The Power Button

Dec 13, 2007

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.

MacBook Pro :: Display Would Not Turn On After Pressing Power Button

Jun 6, 2014

1.turn into black screen after running for about 15 mins, but the system is still running because the keyboard is still functional. After reboot, i record the log as below, it shows that it is a GPU Panic.  

2. display would not turn on after pressing the power button but can still hear the apple start up chime and the system keep running with the screen off. 

3. after erased the hard drive and re-installed Mavericks. Under a new installed system, it can run normally for about 1 day, after that especially after a shut down or restart, the problems above came back.  

I am currently working in Thailand but I have no plan to go back to the US in a short period of time. I brought the laptop to the local apple service, they said it is certainly the logic board or GPU failure and the parts need to be replaced. The cost of the replacement is around half of the price that I paid for this laptop.

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?

OS X :: How To Boot Up From Disc - Pressing C While Starting Up Doesn't Work

Jan 14, 2011

I was trying to boot up from my Snow Leopard disc last night to run Disk Utility (to repair my hard drive). I pressed C while starting up but it took me right to my login screen. I did this several times, no luck. I'm using a 15" MBP btw.

I also tried the same thing on my sister's MacBook (using her own install disc) -- same thing, straight to login screen.

I know pressing C used to work before because the MacBook used to belong to me and I did an erase & install before passing it down to my sister.

OS X :: MAC Partition Doesn't Show Up When Pressing Option At Startup

Feb 18, 2009

Was trying to install Windows XP through BootCamp. The installation did not go through, and I quit it. After I tried to restart the computer however, it kept going to a black screen with a blinking _ on top.

I restarted, pressing the "option" key and the only partition that shows up there is one for Windows. I can't see one labeled "Mac" or something like it anywhere. I tried using the Repair Disk Utility but it won't actually give me the option to repair ir.

Sep 4, 2010

I've read that Early 2008 model MacBook Pros can boot into the Hardware test while pressing the D key on the keyboard without the disc in the drive (or was it the F2 key). I've also read that lots of people succeed doing it. Why does my MBP not do that?

MacBook Pro :: Have To Long Press Power Button To Switch On

Sep 4, 2014

I have macbook Pro running OS X 10.9.4 purchased in 2012 times. For past few days, I've noticed this problem- I have to long press the power button to switch on the device. Normally, the devices switches on with a simple press on the power button. But for the recent days, when I do a simple press of the power button, I think it switches on and goes off instantly. I had to long press (for around 5-8 seconds) to switch it on. After the device is on, there is no problem at all...

MacBook Pro :: Mouse Cursor Doesn't Switch Back To The Arrow Pointer In Safari?

Jun 4, 2014

You move the mouse over to the scroll bar, favorites bar, minimize, etc... and the mouse is stuck in the wrong icon, be it the text pointer, hand pointer, window resize pointer... when it should be the arrow.  It is such an obvious bug and I can't believe Apple hasn't noticed this.

Power Mac :: Switch The Startup Disk On G3?

Mar 17, 2012

I recently developed a problem where my Blue and White G3 Power Mac will not start in OSX. It starts but then displays a screen that tells in four languages to restart my machine. When I restart I just get the same message.This all started when I switched from booting in OS 9 to OSX.  Both had worked in the past.  Now I cannot return to OS 9.  Is there a short cut of keys to press to bring up the start up disk control panel during start up to try switching back to OS 9?

Mac Pro :: ATI HD 2600 XT Hdmi Signal Loss To LCD TV After Input Switch Or Power Off

Mar 3, 2008

Hook up a $3K machine to a $1.5K display and have to hard power down your $3K machine to get the picture back.When I boot everything is fine. If I change input to TV or power off the display, when I power back up or switch back to hdmi input screen displays error, can't read signal check output device. I have read on this forum about a issue similar with ATV but not with MacPro. In my google searches I read some issues with Vista, but no resolution... thought to be a ATI driver problem. Does anyone know of a tweak to fix the ATI 2600 XT to remember the tv signal after you change inputs or power off the display?

OS X :: Installing Tiger Over Leopard / Freezes - Hard Reboot From Power Switch

Oct 31, 2010

I have a 17" iMac G4 that I was rung Tiger with, then I installed Leopard 10.5. I use this as a second computer. All is fine except that my Epson scanner does not work with 10.5. I've tried the latest drivers. I'd like to reinstall Tiger. I used the 10.5 disc to reformat the drive and start from square one. When I boot from my original Tiger disc it starts opening it's windows, but when I get to the point where I can choose Install or use Disk Utility to reformat from the Tiger disc, all windows freeze and I need to hard reboot from the power switch. Am I correct to assume that 10.5 won't let 10.4 to reinstall. Is this correct?

MacBook Pro :: Switch To Another Available Wireless Network And Then Switch Back?

Dec 14, 2010

If I select from the menu bar another available wireless network (one without a password for example) and then switch back to my own wi-fi network, am I still safe?

Did the fact that I connected to another network present any risks?

I did not send any private info during that time, any risks of getting hacked?

MacBook :: New 60W MagSafe Power Adapter Doesn't Work?

Oct 10, 2010

I recently bought a new charger called the 60W MagSafe Power Adapter, for some reason for the first time when I plug it into my Leopard Macbook, it works. But when I take it out and plug it back in, it doesn't seem to charge. I would have to remove my battery and place it in again for the charger to charge my macbook. I don't think the charger is the problem because it charges on my macbook Tiger fine.

Hardware :: Macbook Suddenly Shuts Off And Doesn't Power On Again

Mar 2, 2008

I've had my macbook for about 15 months. i noticed a while ago it had trouble turning off completely when running only on the battery. then a few weeks ago it shut itself off and wouldn't start up again. the power cord indicator was orange, but nothing worked. ordered a new battery, that didn't help. tried a different power cord - nada. i took it in to an apple repair shop and they said something about the internal power connector (i'm not a techy) and took 2 weeks to repair. i've had it back 3 weeks now and the same thing has happened. only this time there is no indicator light on any of the power adapters. and my partially charged batteries do not work on their own either.

any ideas? i don't want to keep fixing the same thing and every few weeks it keeps breaking again. i mean, what's the point in having the computer then, right??
