Sawtooth won't boot with anything plugged into it.

My G4 450 won't boot with anything plugged into it at all. The power will go on but no boot. If I unplug everything (except the power cord) it will boot with a chime. Anyone know what the problem could be?

rs6er:
Well, it's likely to be a problem with the video card, the monitor, or the monitor cable. (I assume that this is your normal monitor which was just recently working on your Mac.)
Some thoughts... Have you tried reseating the video card? Does the monitor power on? Do you have another monitor and cable you can swap and try? Will it boot to Safe Mode ("s" key depressed at startup) with the monitor attached?

Imac G5 won't start with Isight plugged into the firewire port.

I went to turn on my Imac today and it wouldn't start. After checking all the usual culprits (power strip, outlet and power chord) which were not the problem, I proceeded by unplugging all the external devices from the back ports. After unplugging the computer for a few seconds and plugging it back in (which I read resets any power issues), it turned back on. I plugged my Isight camera back in and turned it on and the computer suddenly shut off. I reproduced this quite a few times and it did the same thing. It won't even turn on if any device is plugged into the firewire port. Does anyone have a clue of what this conflict could be or experienced anything similar.
I would greatly appreciate any input.
Thanks in advance,
Daniel

Welcome to Discussions - try resetting your PRAM, if that doesn't work, I'm afraid there is something wrong with your logic board, where the firewire bus is located. The best thing to do would be to take it in for servicing.

Imac won't boot with Ipod plugged in.

60gb 5G Ipod. Imac Intel Core2 duo 2.0 ghz.
About 80% of the time, if the Ipod is plugged in (through a USB hub), the Mac will only boot to a grey screen. As soon as I unplug the Ipod, the Apple appears on the Imac screen. My Iphone is plugged into the same USB hub at the time, with no similar behavior. I've tried restoring the Ipod with no change.
I've tried making sure that the startup disk pref pane is set correctly and locked, but for some reason, whenever I check it, its unlocked again. The Ipod does not appear there. I do have a clone of the startup disk attached to an always on external firewire drive.

Hello Mark
Having the iPod connected during the boot process is confusing the startup manager!
First try: *System Preferences / Startup Disk* and select the *Mac OS X, 10.5.4 on Macintosh HD* then *Click the lock to prevent further changes.*
You can also try ejecting the iPod be for shutting down or only sleeping the iMac when the iPod is charging!
Normally my iMac sleeps, but as a habit I always eject and disconnect all USB storage devices, iPods, cameras, flash drives, etc. be-for shutting down.

Dual G5 won't boot with printer plugged in to 23" Apple Cinema Display

I shut down my Dual G5 the other day due to the excessive
heat it throws out as we were having someone stay in our guest room.
Upon restart next day it would not boot up entirely it would get
to the apple screen with start up wheel (not beachball)
then it would go to a blue screen and stay.
I have cross eliminated the problem to a print device
that I had plugged into the back of the 23" Apple Cinema Display.
I merely unplugged the usb and the computer finished loading up.
I have a slimline keyboard plugged into monitor as well and that does not seem
to cause any problems. Has any one had this problem and or a fix.
Thanks in advance,
Sean

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
Well - presuming that you have inspected the tab on the locating peg of the air deflector for damage - shown in Figure 4 here
http://www.info.apple.com/usen/cip/pdf/g5/073-0891.pdf
and that the booting ok without the deflector, and then running ok with the deflector is a repeatable symptom - there is some discussion of a similar-ish problem here
http://discussions.apple.com/message.jspa?messageID=5748156#5748156
The theory there was that 10.4.10 was picking up on a (real or imagined) CPU-Logic Board mismatch - which may have continued into 10.5.1. As suggested, this may be able to be verified by checking the entries in system.log. If nothing in the log catches the eye, you could copy and post the Startup sequence entries.
There are some things to try suggested there; running the Apple Service Diagnostic is a possible as you still have AppleCare. It would be interesting to hear what they think is the problem.
Please post again if you have any questions. Good Luck.

PC won't boot with X-fi XtremeMusic

# This is my first post, so please tell me if I'm not giving enough info or anything..
I bought a X-fi XtremeMusic and wanted to try out.. So I plugged it into a free PCI slot to find out it wasn't working: I couldn't boot. The only thing that would happen were the casefans spinning, but my screen remained black.
I then tried to boot without the soundcard in the PCI slot, but my screen was still black.. Then I removed the onboard battery from the mainboard and waited a minute or two and put it back in: I was now able to boot again. I tried this one more time and exactly the same happened.
Now I read something about X-fi soundcards and nForce4 chipsets not meshing very well, but I have a gigabyte MA-790XT-UD4P mainboard, so this doesn't apply to me I assume.
Other specs: AMD Phenom II 720
XFX Radeon HD 4870
CoolerMaster 620w power supply
My question is: what could be causing this problem? Or is it possible that my card is broken?
Thanks!

'Re: PC won't boot with X-fi XtremeMusic? Yeah I tried it in both PCI slots, but none worked. Still I wonder about one thing, which I forgot to mention: When I replace the onboard battery and boot I get an error (which I resolve by using the last known good option instead of putting everything to stock value as I'm overclocking in the bios) that the bios checksum is incorrect, so putting in the card changes some value in the bios.. But what value? And does this imply that maybe updating my bios might solve the problem?
Also might I ask what bios revision you are currently using (I'm using the F4 bios)
About the case thing you might also be right: I do have some difficulty putting in the card as it doesn't fit perfectly. I have a CoolerMaster CM690 case which has tool-free fittings, but I can't get the fitting which holds the card down without using substantial force. This also causes the card to be in the PCI slot at a slight angle, I thought this wouldn't matter as the pins still connect, but may this be a problem? I already tried starting up without the case fitting holding the card in place and instead using my fingertips to hold in postion, though to no avail.
Oh and exactly what bracket should I look at (the one you referred to in your post)?

HP Pavilion P7-1141 Computer won't boot with 2nd SATA drive installed

I'm having a problem booting brand new computer when a second SATA hard drive ws installed into P7-1141
Took a working SATA drive from my other computer and installed it into this new computer. But computer only hangs on startup screen after the animated logo draws...then sits there doing nothing..
My configuration:
HD 1 (boot drive, original that came with computer) plugged into SATA1
HD2 (second SATA drive) plugged into SATA2
DVD drive (original) plugged into SATA3
Will boot if I unplug SATA cable, but won't if it's plugged in..
To make sure I didn't break anything, I put the SATA drive back into original computer with the same power cable and SATA cable and it works. That is, it shows up as a second hard drive on my old computer.
Any ideas?

Product number is : QX351AA3ABA
HP Pavilion
Model # P7-1141
Ok. I've done a little research and right or wrong, I'm following a suggestion to re-format the drive before I attach it. Reason: Someone posted that if you had a Windows XP or Vista formatted HD, that it will need to be re-formatted before being installed into a Windows 7 OS. Maybe right, maybe wrong...but I'm going to try anyways. Will keep posted.
Also, looked at my Event Log Errors and found this in the entry:
The device, \Device\Harddisk6\DR6, is not ready for access yet.
Not sure what this means yet..but working on it. If anyone knows off-hand, i would like to solve this.
Anyways, I'm re-formatting the disk now and will try it again. I have my doubts, because why wouldn't an NTFS formatted drive show up with any operating system? Maybe there's an obvious answer, but that's why I'm here!
Other comments:
I checked for latest SATA driver and must have it..at least according to this HP site since it only lists the 'original', so I assume it's there's only one released for this MB and that I must have the latest and greatest.
There are many other posts on Windows 7 hanging on "Starting Windows'..and the above is what I pulled from them...haven't found 'the' solution posted yet....
Thanks!

Nonsense, and very misleading advice. I've updated iPhone 3G, 3Gs,and 4 through itunes many times, never had a problem once, not with one single update in nearly 5 years of iPhones. Of course, I've never jailbroken my phones either. Hack your phone and have update problems? I've got news for you, the problems are not a result of iTunes or Apple's updates.

Dude you have a jailbroken phone as stated in your first post, no need to do a second post.
As per the forum term of service you can't get help here. Use google.
that's the downfall of jailbreaking your phone.

Won't boot with external display connected

My MacBook Pro (circa 1997) won't boot with the external display connected. I can connect the external display (20in flat planel) after it has started, and it works just fine.
I have tried two different DVI cables (one of which I think is a DVI-A cable) and the DVI-to-VGA cable. The result is the same.
During the boot phase I get the tone, the apple logo and the progress wheel. After 30 seconds to one minute those disappear to be replaced by an empty blue screen.

In case anyone wonders, my "solution" was to change to a WB Elements Desktop 3TB (only USB 2.0 is currently available for this model). I miss the speed of USB 3.0, but it's much nicer to not have to remember to unplug and plug in the hard drive each time I boot.
Still hoping to see a proper solution to this (since I don't have the WB My Book anymore, I can't test adaher's suggestion).

IPod classic won't turn off when plugged into a home theater dock; what's up? will it hurt to leave it on all the time?

I bought a new iPod Classic and it won't turn off when plugged into a home theater dock. Is this normal and will it hurt the iPod if i leave it on all the time?

Hi there,
How old is your Classic? Often, after a couple of years, rechargable batteries begin to fail, especially after such a long period of inactivity. This happens with any gadget with this type of battery.
Try leaving it plugged in for 24 hours, and try again, to rule out that it isn't just really low on charge. If this doesn't help, it may be a good time to buy a replacement. New iPod Nanos and Touches will be released this October.
Below, I've linked to an Apple website which explains rechargable batteries, and why yours may not be working.
Apple - Batteries
I hope this helps, and I hope upgrading your device will not feel like an unnecessary expense. Let me know if you have any more questions,
Nathan

My iPhone won't stop vibrating when plugged into my Macbook. All software is up to date. iTunes just gives me an error. No problems when plugged into a PC. Why the nonstop vibrating!?

My iPhone won't stop vibrating when plugged into my Macbook. All software is up to date. iTunes just gives me an error. No problems when plugged into a PC. Why the nonstop vibrating!?

When I connect it to my iMac (with up-to-date OS X Yosemite 10.9.5) - it doesn't work.
Specifically - iTunes automatically launches, but then quickly shows a dialog window that says, "iTunes could not connect to the iPhone. This device is no longer connected."
Meanwhile - on my iPhone - in the upper right-hand corner (where the battery life is displayed) - you can see the "plugged in" icon (lightening bolt) rapidly blinking on and off.
In other words - it seems like, when it's plugged in - it's rapidly connecting and disconnecting (several times per second).
If I click "OK" on that dialog window on iTunes - it instantly pops back up, and continues to do so as long as I keep the iPhone plugged in.
I have tried all and stile did not resolve my problem. I tried to restart both devices, try different cable (I have original cable). Both devices are new and software's are update it on latest versions.
Thanks in advance for any help!

2nd HDD bay with HDD = notebook won't boot with HDD in 2nd HDD bay

I recently came into a Pavilion DV9308 Notebook. It was in decent shape, well looked new and since I like tinkering with laptops and the motherboard had the dreaded NVIDIA GPU failure going on, I sent the motherboard out to my motherboard dude and he put a newer NVIDIA video chip in, made some adjustments and modifications to the heatsink cooler etc. Along with my modifications including vent holes and sealing up the fan blowing assembly so when the fan turned on the hot air would leave the laptop it now runs Windows 7 64 bit with a 64GB Kingston OS SSHD and 4GB DDR2 800mhz ram. It runs like lightning and impresses people when they see it boot up in 15 seconds.
The problem is and the whole reason I picked this notebook to restore is because it has two acutal hard drive bays. Well ever since I've gotten the notebook It will not boot with a hard drive in both bays or a hard drive in Bay #2. I had to send the repaired motherboard back once because one of the ram slots wasn't working so this is happening on two different motherboards. I cannot find a reason why this is happening and have yet to find anyone that can help me with this. Can anyone explain to me what I'm doing wrong? I have all the correct drivers I think and the laptop runs at 130"F when pushed to the max! That is amazing compared to what it originally ran. It would be awesome if someone could please help me with this. Thanks.

Hello jason9922. I understand your notebook won't boot with a hard drive in the second bay.
When you say that the notebook won't boot with a drive in the second bay what exactly do you mean? Does the CAPS LOCK key flash or do you get an error?
When you have the hard drive installed can you access the BIOS? If so, is the hard drive detected within the BIOS?
I'll keep an eye out for your response. Have a great day!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

My iphone4s won't charge while being plugged into any charger/ iPod dock

My iphone4s won't charge while being plugged into any charger/ iPod dock

If the iPhone won't charge when connected to the power adaptor that was included with the iPhone, the same when connected to your computer, and no change when connected to any charger, do you have access to another cable to rule out a problem with the cable being used?
If no change with a known good cable, there is a hardware problem with the iPhone.
Call AppleCare or make an appointment at an Apple Store if there is one nearby.

Biege G3 won't boot with OS 9.2

I purchased a biege G3 MT with OS 8.6 on eBay. Unfortunately, the OS is in French. I upgraded that to OS 9.2 and now it won't boot. No chime and it stops after the first icon during startup. It won't boot with extensions off nor with the CD. I tried resetting pram, etc. without any luck. Loaded it with 8.5 and it works. Took another HD with 10.2 from another biege G3 and it works. It just doesn't like 9.2, but I have 9.2 running in another biege G3. Are there G3 that won't work with 9.2? Please help.
biege g3 Mac OS 9.2.x

Hi elpro,
Here's a bunch of stock responses you'll hear on the G3 forum.
Is the 9.2 CD a universal installer (gold color), or a gray machine-specific CD, and if it is gray, is it the right one for your machine? Apple made gold CDs for general retail to work with all machines, and gray ones that were usually distributed with a machine with the components just for that machine. Unless you have a universal installer CD, the version of OS 9 you are trying to install may not have the right components for your system unless you happen to have one that matches your type of G3. If the 8.5 CD is the right one, and the OS X you say is from an identical machine then that may explain why they boot up but not your OS 9.
If you post your problem on the G3 forum you'll almost be sure to get this question. How old is the battery in this machine? G3s exhibit all kinds of weird and unexpected symptoms when the batteries are weak, and they go through them pretty quickly, especially if they have been unplugged for a long time. The battery helps preserve basic machine configuration information between bootups so if you're having problems with your monitor it might even be related to the battery. If in doubt, replace the battery.
The PRAM reset and extensions off are the other stock replies but you've tried those.

Macbook pro won't boot with two new 4GB RAM sticks.

I have a mid 2010 Macbook Pro. It came with two 2GB RAM sticks. After downloading Lion, my computer started to get sluggish so I thought I would upgrade the ram. I bought two 4GB Corsair RAM sticks and tried to install them. My computer will boot up if I install one of the new 4GB sticks and leave an old 2GB stick; but it won't boot with both of the new 4GB sticks. Any ideas?

Late 2011 Macbooks uses DDR3 1333MHz 204 PIN.
