Aspire One D255 monitor shuts off during boot

Every time I boot, immediately after the kernel lauches init, my screen powers off. About 15 seconds later, it comes back on.
The delay before coming back on seems to be independent of the init process. If I speed init up, by the time it comes back on it's waiting at the login prompt. If I slow it down, it comes back on while init is still running.
I tried adding an echo -e -n '\033[13]' to my init scripts in an effort to unblank the display, but it doesn't help.
This happens both booting of the install image and after installation. It makes it extremely hard to figure out what's going on during startup.
Has anyone seen this before?

I have a similar issue with my aspire one, but the display is not turning off, it is actually the backlight turning off during boot. I use fbsplash with a dark theme but a bright progress bar. During boot, it appears as if the screen has turned off, but looking closely, I can still see the progress bar.
I have tried several different methods of keeping the backlight on to no avail.
Personally I am thinking it is monitor signal detection during a monitor mode reset during boot, ie from console resolution switching to KMS resolution. Most monitors lose signal detection when changing mode (in my experience). Some display a "No Signal" message of some sort, some briefly turn off until signal is detected again, and in the Aspire One case, the backlight turns off. Put it down to monitor manufacturers built in power saving "features".
Tha same thing happens when I boot windows.
Of course, if anyone does come up with a solution, I am eagerly listening!
Cheers.

Monitor blanks off during boot up.

After zapping the PRAM on my G4 (AGP, Ati rage 128 pro) my monitor now blanks off just after the Apple logo in the boot up sequence. The monitor is a Hewlett Packard HPw19 flat screen. In this blank state the monitor shows the message "Attention - Input Not Supported". I'm guessing that zapping the PRAM has switched OS X into a screen resolution that the monitor can't handle. SO....my problem is... how can i switch screen resolution of the video card etc when i cannot use the display? :-/
thanks for any help/ideas

I eventually fixed this by installing a fresh system to the 2nd harddisk - this system booted fine so i could then switch screen resolution and boot from the original system again. Had i had a spare monitor i could have booted from that, switched screen resolution, then plugged in the original monitor. I think it must be an issue with the HP w19 not being 100% ok with OS X.

Mac Mini Shutting off during boot

Hello Everyone - hope I can get some help on this..
I've got an Intel-based Mac Mini, which suddenly (after changing the video resolution - at least that's the last thing I did before this changed), boots to the Apple logo, with the spinning logo underneath.. This then spins for about 30 seconds (normal time), and then the Mac Mini shuts off..
I've reset the SMC and PMU, but no joy..
Help!
Thanks in advance!
SB

Did a full reinstall of Leopard - that seems to have fixed the issue.. A smidge draconian, but effective nonetheless...

IBook G3 (A1005) Shuts off during boot

I recently purchase a used iBook G3 (model A1005) from someone on eBay. I was hoping to set it up for my wife. However, it doesn't fully boot up. The battery lights show that it holds a charge, power cable appears to work. It starts up, makes the nice sound, goes to the Apple logo and spinning dial...but then it shuts off. I am kind of new to Macs so any help would be appreciated.

Does it have a DVD-capable optical drive? Most (but not quite all) Tiger install discs were DVDs.
Ideally, you need both the original system CDs as well as the retail Tiger install disc.
I wouldn't buy any discs for it until you determine if that would have a chance of doing you some good.
Will it start up in _Safe Mode_?

Macbook Pro Lion shuts off during boot up

I have a 13" MacBook Pro purchased in 2011. I had the internet lock up on me and hard shut down the computer. Now when I press the power button, the machine begins to boot up and the apple pops up then the progress bar pops up and the wheels starts to spin, but the machine shuts down about 5 seconds into it.
I have seen this problem on older posts (pre-Lion) and one solution was to hold option during start-up and then boot off th esystem restore disc, but Lion is all internet based, so no disc here. When I do that, it pops the option to select an internet source, which I do, then the HD symbol pops up with an arrow below it. When I clikc the arrow (which is the only apparent option) it does the same thing and shhuts off at the same point.
HELP!

Try booting with command-R. This will boot into the repair parttion. From here you can run disk utility and other programs. You can also do a repair installation of Lion which will almost certainly solve the problem. Doing so shouldn't wipe out your user data, but installing OS updates will be required.

Why does My Mac Book Pro Keeps Shutting Off During Boot Up.

I recently installed office 2008 shut laptop off to take to work then i went to reboot at work and it goes to white apple screen then shuts right off,i went into disk utility and Invalid Key Length then it says the volume apps could not be verified completely. Error this disk needs to be repaired. This is like third time happen .i dont understand and no i didnt do a backup cause its a mac,never had this problem before until upgraded to lion,please help i dont wanna have to reinstall i finally got a my music from itunes,

I am afraid that you have no choice other than Repairing Disk using Recovery HD.
You can download music purchased from iTunes again for free, in case it is lost.
Best.

Macbook shuts off on boot

macbook shuts off during boot after about 15 seconds. During boot at Apple logo, during a fsck process in safe mode, during a boot into Diskwarrior CD, even during a boot into Leopard install DVD. I am a decades mac user and have never had this problem. Tried zapping the pram, tried resetting system management controller (2 diff. ways). 10.5.8 was just installed, but i don't believe this was an issue. I believe it's hardware related. Any ideas?

Hi,
I am having problem with my macbook for like a month now. I is constantly shutting off when I start the pc or sometimes while I am using it. Would you know what the problem is. I tried to update software and it seems better for a bit, then it started again. Do you think the geek squad at Best buy would be able to fix it.
Thank you very much.

HP Pavilion a1730n shuts down during boot

Have been using the Desktop Pavilion a1730n for several months after upgrading to Windows 7 Pro 64 bit. Without any warning signs, now the CPU shuts down during boot up. When I shut the main power supply switch off and then turn it back on, then switch the CPU on with the front on/off button it gets 15-20 seconds into the bootup and then powers off spontaneously and completely.
If I try to start it immediately again without turning the main power supply switch off then on and only depress the front on/off switch, it starts to boot but only gets about 10 seconds (varies) in to the boot process before in shuts down.
What could this be? the power supply? the mother board?
ANY ideas would be appreciated.

Hi , Sounds like the power supply , when a load is put on the supply it does not seem to be able to cope with the correct output . You can buy a new supply ( same watt output or better )eg; if you have a 400watt supply get 400watt or higher supply as replacment . Checkurtech

PowerMac shuts off during bootup

This morning I woke up to find that my G5 tower was powering off during boot ups. It would turn on the, I'd hear the apple chime, the fans would start, nothing out of the ordinary, then the gray screen with the apple logo would pop on screen as per usual, but then a second or two later I'd hear the "click" that comes just before I'd turn off my computer coming on when I didn't turn it off.
I've turned on the computer 2 more times and the same result. It turns off at the exact same place everytime. No sooner, no later.
My Power Mac G5 is the last model made just before the Intel upgrade. I made no software or hardware changes recently that preceded this issue. I pressed the SMU button to no effect.
Suggestions?

Been there, done that (see thread link at the bottom). Here's my initial suggestion mix for this problem.
Have you tried a Safe Boot (hold down the shift key while booting)? If it comes up in Safe mode, then I would suspect a power-supply issue, but that requires a little more troubleshooting.
If you do get it up in Safe mode, look at your system log file using Console. (Click the Logs button which will reveal more log files.) Look for a log entry along the lines of (you have a later machine and are running Leopard, so the nomenclature might be different):
*localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122*
Now, where to go from there assuming you start up Safe OK. What is probably happening is the machine is probably executing a test in the normal startup that is "flexing" as it were the power supply, which is not responding quite like the SMU expects. This may be caused by something as simple as dust accumulation in the power supply. The G5 supplies can build up a considerable amount of dust, which needs to be blown out. This might be able to be done with canned air, realizing that you will stir up a bunch of dust, so it should be done outside somewhere.
Also, you can get more info by doing the verbose boot, holding down the command-V combination when powering up. You will get a dumb terminal display of what is going on. This will verify at least that it is truly powering down at the same place in the boot. There are three ways to set verbose boot as a default for the machine, should you decide to do this.
Method one requires using terminal (you can do it after safe boot) and using the following unix command:
*sudo nvram boot-args="-v"*
You can also use open firmware, in the following manner
*set-env boot-args -v*
Or you can boot single-user mode (command-S at boot, then issue the terminal command above without the sudo, which is unnecessary in single-user mode.
I just went through a similar situation a month ago, see http://discussions.apple.com/thread.jspa?threadID=2452255&start=0&tstart=0 and I ended up replacing my power supply, though the dust blowout might have worked as well.

[SOLVED] USB Harddrive via fstab turned off during Boot - Error

Hello^^
I'm trying to mount my external USB Drive.
I put the following line in fstab:
/dev/sdb1 /media/Musik ext4 noauto,user,default 0 1
I only want to start the Harddive occasionally.
The problem is, when the drive is completly turned off during boot I get the following error:
No such file or directory while trying to open /dev/sdb1
Possibly non existend device?
I thought that the noauto Option should prevent fstab from mounting the hdd???
regards

PS: Manual mounting works without any problems...

Let me give you a hand then. The following I have in my /etc/udev/rules.d/11-media-by-label-auto-mount.rules, and what it does is:
-- pick the name of a drive,
-- create a dedicated /media/mountpoint name (certainly, "mountpoint" is replaced by the name of your drive),
-- mount the drive on boot,
-- unmount the drive on shutdown and delete the /media/mountpoint.
KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"
# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"
# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask=002"
# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"
# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"
# Exit
LABEL="media_by_label_auto_mount_end"
Plenty of handy examples you can find in /lib/udev/rules.d/ and modify them so they meet you needs. I hope it clarifies the matter a bit.

N200 shuts down during boot

Dear Lenovo,
I have a problem with my N200 laptop. Notebook shuts down during boot. Sometimes it is immediately after "Lenovo screen", sometimes it is when Vista logo appears. I found out that this is always when notebook is "cold". It does't matter if I want to switch on my notebook or if I want to restore it from hibernation or sleep mode. Next thing is that it always crashes when fan starts work at full tilt (I checked the fan but it is clear). When notebook starts correctly then it works without problems. Usually I have to switch it on about three times then it is OK. This problem takes about 2 weeks. I have my laptop about 7 month. Do you have any ideas how to solve this problem?
And another thing - I forget to send registration card to Lenovo and now I am afraid that I will be without warranty. Can I send it still now?
Thank you for answer and sorry for my English.
Gabi

Yes, problem with the video card sounds plausible! Any not so successful updates recently? It is sometimes to make a good uninstall, which is required to make a good install.
4in1 drivers should - esp. with W98 and ME - be installed while in SafeMode and with all autostarting programs disabled, for example Antivirus and utilities.
Else, since you have a damaged regedit, I would reinstall Windows. You might have done something for example an upgrade or new install the registry, not healthy, has made a note of. Some utilities also overwrite and change system files without good results.

I can only start my iBookG4 after deleting preferences. I have to go into single user mode to do so. If I don't go into single user mode, the computer shuts down during boot up. What might be the problem?

I do not have a startup disk. I did try fsck (based on what I learned from your reply-thank you). This failed (fsck); here is the message:
** Checking catalog file.
Invalid key length
(4, 8198)
** Volume check failed.
/dev/rdisk03 (hfs) EXITED WITH SIGNAL 8.
I am sure this is an easy fix; I just have no clue how.

MacBook Air shuts down during boot

My Macbook Air (OS X Yosemite - Early 2014) automatically shuts down during boot, with the screen flashes during the loading bar at 40% and then shuts down. I've tried to reboot many times but it wouldn't get past the 40% on the loading bar.
I've also tried the following but none worked:
The Apple Hardware Test shows that "There may be an issue with a memory module." (PPM002, PPM003, PPM004) - though I've checked that the reference code and the definition doesn't match, as "There may be an issue with a memory module." should be PPM001, and PPM002-PPM015 should be "There may be an issue with the onboard memory.". I've sent this message to Apple and they'd only provided the option to visit their retail store.
Also, the Recovery Mode isn't much help either. As do not have a backup of my HD, I'm not able to restore from Time Machine Backup.
So, I've tried to reinstall OS X Yosemite, but it says "Unavailable to install OS X". A website online says that you can resolve this issue by correcting the date through terminal, but the basic menu bar won't appear, in which I'm not able to access Terminal during the Recovery Mode.
Therefore, I've also tried the Disk Utility, which it shows it can't be repaired, with the following messages: Invalid Node Structure (4, 57963), and 2 messages regarding the Invalid Extent Entry (4, 47013) and (4, 40808). The Single User Mode with the command fsck -fy yields the same message.
Is there any other options then to visit the Apple Retail Store?

Invalid node structure
I'm pretty sure you need more then Disk Utility to repair the drive.

Assuming you have Snow Leopard installed, you can try reinstalling the Mac OS but you'll have to do this from another Mac.

Battery shows over half charge then shuts off during use.

iPhone 5 w ios7 shows over half charge in battery but shuts off during use listening to pod cast for example. When placed on the charger it takes a couple of minutes then shows over half charged again. What's wrong?

Hi
If you have tried restoring and all the possible fixes you are still well within your warranty period book a genius appointment and they will offer you a repair or replacement.
Hope this helps
