Mini won't start with firewire drives connected

to all,
please ignore the specs below. the computer i am talking about is the 1.66 Intel Core Duo, 1 GB RAM OS X 10.4.7.
as per the title, the mini will not start up if there is a FW drive connected. my wifes amacom flip 2 disk, the Iomega drive specially deisgned for the mini, or my lacie pocket drive. the screen shows the apple but the cog does not appear. it immediately appears after the drives are removed or powered down.
is there a solution for this? or do we have to live with it? or am i alone in experiencing this? there are no other operating systems alive on any of the FW drives to start from.

Hold down Apple-V right after you hit the power button. That will put you in verbose mode, so you should be able to see whatever is keeping the kernel from loading.

SatelliteU300 Won't start with AC power connected and fully charged battery

I just bought a U300-13U. It works great when battery is charging and AC is connected. However if left to charge up fully it won't start with AC connected. Unpluging the power or removing the battery and running on AC makes it work fine. Is this a 'feature' to stop overcharging or overheating the battery, or just a problem with this machine. I want to run with AC and battery both connected all the time as I have done with all my other laptops.
Any help appreciated.

Hello Andy
Friend of mine has this small U300 and everything work well. I have had it few weeks ago to test WXp installation and it works perfectly.
Please test it again very carefully and if the same happen again I recommend you to contact Authorized service partner in your country. Let them check your notebook. I must be honest and say that described issue sounds strange to me and please do not wait too long. Contact service as soon as possible.
Bye and good luck!

Mac Mini Won't Boot with VGA Monitor Connected

I have a new Mac Mini connected to an older VGA monitor using the Apple brand VGA adapter. The mini is fully up to date and runs perfectly when booted. However, if I reboot the mini with the VGA monitor connected, it fails to boot. I just hear the faint chime sound every other second. There is no output to the monitor and the only way I can get it to boot is to disconnect the monitor and then power cycle the mini. I can reconnect the monitor just seconds after powering back on and it finishes booting properly.
Anyone else experience this? It is very frustrating. I've also tested with an HDMI connected monitor (without the VGA adapter) and it boots just fine and the display works properly.
Thanks!

Okay, I'm back with good news: I have found two remedies for the problem which will hopefully solve it for you as well.
Given that the issue only occurs when certain monitors are connected, I concluded that the root of it must be a bug in the Mac's firmware related to DDC (Display Data Channel) handling, and that the most promising way to address it should be to just disable the DDC.
Workaround #1: If your monitor has BNC connectors, use a VGA to BNC cable.
In this configuration the DDC pins are not connected to the monitor at all. This did indeed fix the problem - my Mac mini booted without a problem with the monitor connected. However, I was not completely satisfied with this solution, because VGA to BNC cables are usually quite heavy and inflexible, and do no go together well with Apple's MDP to VGA adapter and the Mini Displayport/Thunderbolt port which has no locking mechanism.
Workaround #2: Remove pin 12 of the VGA plug.
Pin 12 of the VGA plug connects the serial data line of the DDC. Pulling out this pin with a pair of needle nose pliers will effectively disable DDC. I hesitated to do this to my cable (a direct MDP to VGA cable which eliminates the need for a separate adapter dangling from the Mac) and therefore bought a tiny VGA male to female adapter (also called port saver, e.g. Delock 65250) to perform the surgery on that. This has done the trick and my Mac mini has started up fine ever since.
Of course, without DDC the Mac won't know the model name and capabilities of the attached monitor and thus offer some resolution and frequency settings which the monitor may not support, but that's a small drawback compared to having to pull out the monitor cable everytime you turn on or restart your Mac.

Mac Mini won't start with scheduler after power loss

Hello,
I have a Mac Mini here. It is configured to start at a certain time (say 1:00 AM). In the evening I shut down the Mac Mini and power off the socket where it is connected. In the morning I switch on the power socket and the Mac Mini is not starting.
When I do the same thing with an iMac everything works. The iMac will start because he missed the 1:00 AM.
I checked this with the current Mac Mini MC815D/A: here it works again!
So, what is wrong with my Mac Mini? I have this model:
APPLE #MAC MINI 2.4GHz (MC270LL/A)
Model No: A1347 (EMC 2364)
Model ID: Macmini 4,1
Can this be verified my some other user?
I use the latest firmware, and this behaviour shows up on several OSes (Snow Leopard, Lion and Mountain Lion)
Best regards
Matthias

Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move these files to the Desktop.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist

Then reboot once more.

IMac won't start with Thunderbolt Display connected after firmware update

After updating my thunderbolt display firmware to version 1.2 this morning via the App Store, my mid-2014 iMac won't start up with the external display connected. I can get the iMac to start up only by disconnecting the display's thunderbolt connector. After the iMac comes up, I can reconnect the display and everything appears to function normally. I've tried several restarts and the iMac won't start up with the display connected. Anyone else experience this?

Freezes when waking up with Firewire drive connected??

When you put your mac to sleep are you supposed to unmount your external drives(firewire)? is this different for firewire vs. usb?
I have a Dual 2GHz G5 and an Iomega "black" 250Gig external hard drive connected through firewire and many times (not always) when i put the computer to sleep or it goes to sleep by itself when it wakes up the computer freezes (spinning ball) but un-freezes if i pull the firewire cable.
what am i doing wrong?

There could be a problem with the FW drive's firmware. Older, non-standards-complying versions have been known to do stuff like this, especially with newer Macs that are more stringent in what they tolerate. Check with the manufacturer for updates.

PremiereCS3 won't start when firewire drive is removed

I've had to remove a Lacie firewire drive to reformat it on another system but now Premiere will only flash the loading screen and then dump out (no error messages, just shuts down) when I try to start it. Is there a way to start up Premiere to get some work done while this drive reformats?
BTW this drive was not used to store any media.
Thanks in advance.

Rename your PPro

BootCamp won't boot with USB-drive connected

Hi everyone,
since I installed my BootCamp partition I encounter a strange problem. I have an LG external DVD-drive connected via USB to my iMac. Everytime I try to boot Windows while the LG is connected the boot process just stops and gives me a white display. If I unplug the drive from the USB-Port everything works fine, and once windows is booted I can even reconnect the USB-drive and it works fine. But as you might understand always unplugging and plugging really gets to my nerves. I know of a couple friends who encounter the exact same problem, they also complain about this...
Also strange is the fact, that if I boot OSX the LG is connected and everything works fine...
Searched the forum and web, and wasn't able to find something usefull...
I hope there is somebody here who can help me...
Thanks in advance...

I think your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from if you don't have another boot drive...

[SOLVED] Xorg 1.16 updated and won't start with Nvidia driver

I tried updating to xorg 1.16 yesterday and after rebooting everything stopped after "[OK] Reached target Network."
I was able to switch to a different terminal and downgrade to xorg 1.15 to boot again.
I've seen https://www.archlinux.org/news/xorg-ser … available/ but I'm not sure what it implies I need to change to get it to work. I am running Gnome 3 with GDM.
I'm fairly new to Arch so any help to get me moving in the right direction would be great.
Thanks,
Justin

That fixed it! You guys are awesome.
For other's reference...
Once booted press Ctrl+Alt+F2 to get another terminal. Log in and type the following to downgrade the xorg packages.
cd /var/cache/pacman/pkg
sudo pacman -U xorg-server-1.15.2-1-x86_64.pkg.tar.xz xf86-input-evdev-2.9.0-1-x86_64.pkg.tar.xz
sudo reboot
Once it reboots you should have your desktop again. Run nvidia-settings and go to X Server Display Configuration. From there click Save to X Configuration File and save the file as 20-nvidia.conf. Then move the file to /etc/X11/xorg.conf.d/20-nvidia.conf if you saved it somewhere else.
Upgrade back to xorg 1.16 and reboot.

Mac G4 won't boot with slave drive connected

I have two G4 boxes. 1-Dual 867 Leopard and 1 -Dual 1.25 Tiger.
I have been trying to clone the system drive of the Dual 867. Everytime I add the second drive to the 867 box and try to boot i get the "Flashing ?." I have tried various reformatted drives and the result is the same. I have even tried to accomplish this by using the 1.25 box. Same result.
if i unhook the 2nd drive (ie backup drive) both computers will boot as usual.
What is the problem?

Hi larbok, and a warm welcome to the forums!
I think it's the Jumper settings on the Hard drive.
Older G4s should be set to Master on the end cable & Slave for the Middle of the cable.
MDD usually use the Cable Select jumper settings on both drives.
Jumper settings are generally shown on the HDs themselves.

Mac mini won't start up. Grey screen with apple just freezes.

Mac mini won't start up. just get a grey screen with the apple and it freezes. Please help.

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Windows won't start with Nano connected

My computer won't startup or restart with the nano connected to the USB port. It just hangs on the startup screen. I have to disconnect the nano and do a hard power off and then power up again then connect the nano after computer is started. Everything works OK then. Is this normal? Using Dell 8500 laptop with XP Pro sp 2.

I have the same (or similar) problem with an iPod Video 30GB, and have found a solution. It is not a boot order problem. I've just posted the following as feedback to http://docs.info.apple.com/article.html?artnum=93953
There is also another reason why a PC may not start with an iPod connected. It is also related to USB, but is a different problem, and there are different work-arounds available.
Problem: PC will not POST or boot with iPod connected to a USB port
Description:
With an iPod connected to any USB port, the PC will not pass power-on self test (POST), and does not attempt to boot. It remains completely unresponsive to anything except a hard power-off; in particular it is impossible to reach the BIOS configuration screen. This is not a problem with the boot order: the internal disk is first in the boot order, and in any case, POST is not passed and so booting is not attempted.
With the iPod disconnected, the PC boots normally, and if the iPod is plugged in later, the iPod and iTunes function normally.
Solution: either:
1. Disable "USB legacy mouse support" and "USB keyboard and legacy support" in BIOS. Disabling legacy USB mouse support stops a USB mouse being used by BIOS and DOS programs, which is not usually a problem. Disabling "USB keyboard and legacy support" will prevent a USB keyboard from being used at all, which is a potentially serious problem.
2. Boot with the iPod disconnected.
System details: a PC based on the ASUS A7N8X v2.0 motherboard running BIOS version 1008. It has a USB mouse, PS/2-compatible keyboard, and a USB-connected printer and scanner as well as the iPod.
Comments:
This is not necessarily a bug with the iPod, but may be. There are three possibilities:
1. There is a bug with the BIOS implementation of USB keyboard and mouse support
2. There is a bug with the way the iPod responds when the BIOS is looking for USB keyboards and mice.
3. There is a bug in the USB spec itself.

Mac Mini won't start and constantly makes disc ejecting noise

My Mac Mini won't start. It was working fine, then just locked up and won't start again. When I push the start button it just makes this repeated disc ejecting noise from the DVD drive. It doesn't make the chime noise or display anything on the monitor. I've disconnected the optical drive, but it didn't help. Then it just doesn't start at all. I thought that if I would disconnect the optical drive, that it would ignore it and just boot off the hard drive, but nothing happened. The power light comes on. Then, if I hold down the power button for 10 seconds it shuts down. The fan operates. It just never attempts to boot up. I can't put in a system DVD because the optical drive is just in eternal eject mode.
If you have any suggestions let me know. Thanks.

I have the same situation.
I think the drive thinks it has a disc to eject or part of the mechanism is stuck and can't return to it's resting position. I was going to disconnect as you tried but now I think I'll try to disassemble the drive to see if there might be some debris jamming things up.
Please let me know if you solve the problem.
