Help!!! ibook automatic sleeping after startup

my ibook fell down from the desk, the display is broken, so i remove the display and all the cable of the display. then i connect another LCD. the ibook sleeping after startup. so what's wrong with it? anybody can give a solution?

It could be that you've damaged the system which checks whether the laptop lid is closed; whatever the cause of the problem is, it sounds like you need to get it repaired if it's fallen off a desk and the display is broken!

Please Help: iMac black screens after startup logo + spinning wheel no cursor).

Hi, guys.
I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
I've tried rebooting over & over again; the results are the same.
The steps that led to the problem occurred thusly:
1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
2 - One particular process I quit was 'launchd' which was functioning under my profile username.
3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
Thank you I'm advance to anyone with advice on how I can go about fixing this.

Gray screen appears during startup

IBook flames out after startup

A friend's iBook started freezing soon after startup. That problem has now escalated to spontaneous shutdown either during or shortly after startup. The same thing happened when I tried to boot the iBook in target disk mode. Any ideas what's going on? Is the motherboard fried?
One additional detail: "About this Mac" reports that this iBook is a 1.07GHz G4. I doubt that such a model exists.

Hi, I just had the same trouble, I have a 1.33Ghz iBook, The screen went black and had random shutdowns. After looking at the system console, I looked this line:
May 27 23:40:56 localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -127, found that after some time the PMU needs resetting, so it can work properly again.
I tried resetting the PRAM and the PMU, and Boom, now working nicely

Note that when you reset the PMU, the computer instantly restarts, so don't do it when working or anything…

Mac Won't Automatically Sleep After External Hard Drive Connected

I use my Mac Mini as a media server that is set to sleep after 5 minutes of inactivity. It worked pretty well, but I outgrew my hard drive and recently purchased a MyBook Studio drive to add extra storage.
Unfortunately, when connecting my drive, my Mac Mini never enters sleep. My external disk will enter sleep (a feature it has), and my monitor will turn off, but the computer just won't sleep anymore!
I can also manually sleep without issue, so I'm scratching my head a little over what could be happening.
It may or may not be relevant that the external disk installed a program when first connected, which I've since uninstalled.
Any ideas?

Colin,
No solution for you, but I just want to add that I installed a MyBook Studio II a few days ago and I have exactly the same problem. Didn't have time to investigate a lot yet.
Latest Snow Leopard on my Mini.

HELP! Black screen after startup after Yosemite installation

Urgent help please.
I Have a late 2010 MacBook Pro and today installed Yosemite. It appeared to install ok, but now on startup it gets past the apple logo screen then just goes to a black screen with a cursor. I have attempted a safe boot, and it manages to get to the login screen, but it won't accept my password, it just keeps on loading the login screen over and over. Would love an answer please...I am completely puzzled!

Ok, I am a couple of days ahead of you. I had exactly the same issus on a mid 2010 mid MBP. Mine failed after the install, although it worked fine for a few minutes untill it went into Sleep. When it came back on it was in color But you could not really see, Another reset and all went black.
After an hour on the phone with support on Sunday who suggested trying a system management reset. Solved nothing. I went to my Genius apt on Monday. Two hours and 15 minutes waiting in line And finally I got my Genus.
Again a nice guy trying to help, but other than pulling the connector to the screen and getting back my comprised color negative screen no real progress. "I know it sounds like a strange coincidence but maybe you display went bad." Well perhaps you can get hit by lighting twice in a row while humming "Oh, What a beautiful morning" but I did not think so.
I was more lucky back at home. I recently installed an SSD, so I took it out and booted with the old drive and booted 10.9.5. Display was fine. So this proved the issuse was Yosemite install. Here is the good news, when I put the SSD back in everything was great. i know you can't do exactly what I did. Here is what I suggest..
I believe the issuse is bad video driver with Yosemite during the install. rreinstall Maverick or boot from another drive with OPTION. . I believe it will work fine. Then if you are lucky perhaps your Yosemite will work as mine did...

IMac G5 *no isight* Wont automatically sleep after 10.4 update

We have had our iMac G5 since the first day they released it, and it has been perfect. Recently we bought an iPod, and it would not work with our computer so we brought it to the apple store and they made it so it had 10.4.11. Before it had 10.3. It slept automatically up until we updated to 10.4.11 and just the display sleeps now and the computer never sleeps even after a few days. We added shockwave, flash player, and adobe reader 8 for mac also but nothing else has changed. Thanks! And we also reset the SMU and PRAM and it still doesnt sleep.

Try this (some you may have already tried):
Change the energy saving options, to put the display to sleep and the computer to sleep at the same time.
Enable (check mark) put the hard disk to sleep when possible.
Lock the padlock.
Repair permissions &/or restart.
==============
Double check your Energy Saver settings to make sure they are correct.
See if you can put your computer to sleep w/your remote.

Help, ibook not booting after installing update 10.4.8 combo

Hi there,
i just updated my ibook 500 dual usb, with 10.4.8 combo and when i restarted the screen was gray with a flashing question mark.
I tried to boot in every mode (with x, with startup manager) and also i checked with disk warrior and disk utility and the hard drive is fine.
Any idea?
Thanks
Marco

Well, if disk utility shows the disk, as well as disk warrior, I would move on to reset the PRAM (http://docs.info.apple.com/article.html?artnum=58042). If that does not work, I would run disk check from disk utility on the install cdrom. If that does not work, I would move on to an archive and install. Please check:

Automatic "Sleep" Functional for Anyone after 10.5.2?

I'm wondering if anyone's "sleep" works after 10.5.2? If it does now, but didn't at first, what steps did you take to correct the issue? Is this failure-to-sleep problem restricted only to Intel-based systems?

Hi Daddy,
I do not wish to appear offensive... but you've still not told me if you have an Intel-based Mac with OS X 10.5.2. Details at the bottom of your post do not clarify this issue!
I would like to know if anyone with this configuration now has a perfectly functioning automatically timed "sleep." This question has either a "yes" or "no" answer. I am particularly interested in hearing from those who experienced an unresponsive automatic "sleep" after upgrading (i.e., an initial "no") who have subsequently found a "fix" that reinstates a functioning automatic (timed) "sleep." If no one in this category responds within the next day or so, I'm obliged to infer that all Intel-based Macs (and possibly others) most likely experience this problem after updating to 10.5.2. +I view this as a truly minor inconvenience as I remain able to put the computer to sleep manually.+
However, I have acceded to your request: I dismounted both FW drives (physically and electrically). The Mac was rebooted with no open applications --- the monitor shut down at the specified time (after approximately 10 minutes of inactivity), but the Mac *+did not+* go to sleep even after waiting another 15 minutes beyond the specified time! I still have not tried booting with an unplugged USB keyboard/mouse...

IMac will not auto sleep after 10.5.7 update with Safari 4 Beta

I've noticed that my new iMac 24" will not automatically sleep after updating to 10.5.7. Actually, that's not completely true, I've just discovered that if Safari Beta 4 (latest update) is open the iMac will never sleep automatically, but that if Safari is not open, automatic sleep works perfectly as it always did with 10.5.6. I've repeated this test numerous times and it's always consistent. Anyone have any ideas how to solve this?

Sorry that I do not remember where I saw this, could be MacFixIt, but the advice that I saw for issues with the 10.5.7 delta that comes through Software Update for folks with 10.5.6, was to download and overlay the 10.5.7 Combo as Carolyn has suggested, and then to download and install the most recent beta for Safari 4.
Of course this is best done without multitasking while the installations are happening, as well as unplugging and shutting down all other processes; external attachments and even Bluetooth and Air Port. Prepare for the installs by rebooting to your Install DVD and use Disk Utility in the Utilities Menu to verify and repair any issues with your boot volume, followed by rebooting into your account and using DU in Apps/Utilities to Repair Disk Permissions before and after the installs.

Imac 24 won't sleep after installing Airport Extreme

Hi there.
This topic may have been covered already, but does anyone know why I can't seem to get either my Imac 24 display or the internal HD to automatically sleep after installing the Airport Extreme .11n?
Both the display and internal HD would sleep just fine when directly connected to modem, but now with Airport Extreme, only the screen saver appears and I can't get either the display or drive to sleep.
Thanks

Hmm, check your settings for sleeping.

IBook Will Not Automatically Sleep

Lately I have had a problem with my iBook G4 not automatically going to sleep after the specified period of time. Obviously this is a problem when running on battery power! I usually have it set to sleep after 15 minutes of inactivity to save the battery, but it will not go to sleep. I'll come back a few hours later to a dead battery. It does sleep when I shut the lid, and it goes to sleep fine when I select Sleep from the  menu. It will also go to sleep when the battery is low (about 2%). It just will not sleep after the interval that I set.
I have tried the following:
Deleted the powermanagement.plist file then rebooted.
Verified the HD and repaired disk permissions both from disk utility and install disk.
Tried the cmd-shift-option-power reset option after shutting down, still the same...the iBook will not go to sleep on its own.
No software is running, no additional RAM has been installed, and this happens on both battery and AC power. Any thoughts?
iBook G4, 12" 1.33 GHz Mac OS X (10.4.9)

Restart and hold down on the "shift" key until you see the spinning gear icon. This will startup the iBook in "safe" mode. Test to see if the iBook sleeps normally now. If it does, then you have some kind of third-party software conflict. If it doesn't, then you might consider resetting the Power Management Unit:

"cmd-shift-option-power" is not the same thing as "control-shift-option-power"...

Mount usb hdd automatically at or better after startup

Hi,
i wanted to mount my external harddrive shortly after archlinux has booted into GUI so it doesn't slow down the boot process.
I was thinking about something like (sleep 10 && modprobe usb-storage && mount /media/usbhdd) & in rc.local but that didn't work for me.
That's not my only concern though because I can't even get the drive to automatically mount at startup via fstab entry.
I tried this and many variations:
/dev/disk/by-uuid/DEFC3BD4FC3BA5A5 /media/usbhdd auto rw,user 0 0
Any thoughts on how i get the drive to at least mount at startup via fstab or even better in form of some script shortly after the boot process is almost finished?
Thanks,
demian
Update: Solution is
(sleep 8 && mount -t ntfs-3g /dev/disk/by-uuid/DEFC3BD4FC3BA5A5 /media/usbhdd) &
or if you have an fstab entry
(sleep 4 && mount /media/usbhdd) &
in rc.local

I didn't want to use udev rules because it's a server and i usually don't have switching periphals. I prefer having everything static.
I just tried using a udev rule though and it kinda crashed my system . Guess i made a typo in the .rules file or it simply didn't work with the current udev.
Anyhow, i found a solution.
In rc.local:
(sleep 8 && mount -t ntfs-3g /dev/disk/by-uuid/DEFC3BD4FC3BA5A5 /media/usbhdd) &
Since i have an fstab entry, i now use (sleep 4 && mount /media/usbhdd) &.
I don't know why it didn't work before though, when i tried it with (sleep 10 && modprobe usb-storage && mount /media/usbhdd) &. Probably bad syntax or because of the modprobe insertion.
Anyway thanks guys!
Regards,
demian

Firewire disk automatically ejects after sleep mode

I have Maxtor OneTouch Firewire drive that occassionally will automatically eject after after my system awakes from sleep mode. Usually just need to power down the disk and then power back up for it to reconnect, but sometimes that doesn't even work. I have latest firmware from Maxtor, but that didn't help. This is really starting to annoy me. Any ideas?

No ideas? anyone??

No automatic connection to a wireless router after startup!

After adding a new wireless router to my home network an iMac G5 does not automatically connect to the wireless network after startup.
And so the story began: I'm running a wireless network for years without problems at my home. The wireless router is a Orinoco 102.11b with 128-Bit WEP encryption and I have 4 different Mac connected to it.
Because I wanted to use the higher 54 MBit/s speed and a more secure encryption for my network I've installed a LINKSYS wireless router and configured it for 102.11g and WPA2.
Everything worked fine except the automatic connection after restart on my iMac G5 running Mac OS 10.4.10. I can connect to the new wireless router but I have to do it manually after each restart. The password is therefore stored in the login keychain. The connection can be established automatically after sleep but not after startup...
So I switchted the connection back to the old router and got unfortunately the same behaviour. The iMac does not connect any more automatically to the router after startup. I removed the new router from the network, deleted all wireless passwords from the system and login keychains, created new keychains, switched back and forth the preferred vs. automatic network selection, created new locations, changed the root password and so on...
It seems that the new password entry in the system keychain causes an error in the password encryption of the system keychain which prevents the automatic connection to the network after startup. Replacing the keychains from my backup does not work either after I've once created a the system keychain.
Is there any log file, which may proof my assumption or can give me some more information of the erroneous login process to the wireless network during startup.

One thing that can work, try this, *please ignore the exact symptoms and connection and Hardware types*, it's worked for many others than the stated...

After ram upgrade automatic sleep is not working anymore

Some days ago I installed a second 1GB ram module in my 20" Intel iMac. After this I noticed that the automatic sleep do not work anymore. The display turns off but the iMac not. The iMac makes sounds like he wants to do to sleep but could not.
I tried everything I could find... delete OS X powermanagement prefs, run Onyx, reset the SMC.
Do anyone have an solution for this?
Thanks

Does your iMac recognize the new memory module?
Yes.
You might try reseating the module in its slot, and it
would not be a bad idea to run Hardware Test from
your install/restore DVD, just to be sure there is
not an underlying hardware problem.
Already done - no problems reported
Is your new memory module of the same specifications as the
stock module?
Yes it is the same, I had a look on this before I bought it because I wanted to use the dual-channel mode.
Also, what are your settings for sleeping your iMac?
5 min to sleep display, 10 min to sleep the mac
One other thing you may wish to
try is updating your system of OS X 10.4.6 (your
profile indicates that your a running 10.4.5).
Was updated to 10.4.6. I just forget to change the forums pref
I more thing to mention when I start the sleep mode manually everything is fine. I also tried to disconnect all external USB/Firewire hardware and tried it with a fresh mac os install on my USB HDD.
Nothing helped.
Thanks
