"System must restart" on battery power

Hi all,
Recently I've noticed an issue that I just now was able to find some consistency to on my MBP. Whenever I'm on battery power, in under 5 minutes of unplugging, the screen will fade from top to bottom to a dark color and I get a message telling me I need to restart. The computer is less then 8 months old, so I doubt its a bad battery (During the USGP a couple weeks ago it was fine!). Any suggestions on what's happening? It will crash whether 10 or no applications are open.
On a related note, how do I see what the error report says? On every restart I get a message where I can Report or OK, I ALWAYS click Report but get nothing afterwards.
Thanks your help!

Okay, here is the latest one. I'm unsure about what I'm looking at, so if someone could decode it for me I'd appreciate it.

"You must restart your system" error when installing Tiger on a new drive

While trying to install Mac OS 10.4 from the install DVD the install stops during the "Basic Install ..." phase and I get a gray screen that says "You must restart the system by pressing the power button ....." shown four different languages. I restart installation over and over, it never gets past that first section. Gray screen, panic stop.
I installed a new 200 GB Maxtor DiamondMax Ultra ATA/100 hard drive in my system. The system already had a 120 GB Maxtor. The 200GB is configured as the master and the 120GB as the slave. I have a new SIIG Ultra ATA/133 2 Channel PCI Interface (https://eshop.macsales.com/item/SIIG/SCMP4A12/) also installed.
Here's my configuration.
Power Mac G4 (AGP graphics) 1GB RAM, Mac OS 10.4.8
- SIIG Ultra ATA/133 2 Channel PCI Interface
- IOGEAR Hi-Speed USB 2.0 / FireWire 400 (1394A) Combo PCI Card
- MAXTOR STM3200820A (200 GB drive, master)
- MAXTOR 6B120P0 (120 GB drive, slave)
I tried disconnecting the 120GB hard drive, leaving just the 200 GB on the bus and I get the same gray screen a few seconds into the basic OS install. Tried removing the IOGEAR USB 2.0 card, same message. Since Mac OS X was originally installed on the 120GB, I can restart Mac OS 10.4.8 from that drive and use that drive. Once restarted on the 120GB drive I see the 200 GB drive, Disk utilities see it just fine, drive reports no error in the Disk Utility. The 200 GB disk even formats, I see it on my current MAC OS 10.4.8 as the second drive. I just want to get Mac OS installed on the 200 GB.
If you have seen this gray screen before installing on a 200 GB Maxtor or have any insight I would be most appreciated.

Hi Frank,
With all that additional third party hardware it will be difficult to get a proper installation. You can either take out ALL 3rd-party hardware (just leave the 200 GB hard disk in there, but also take out the 120 GB) or you can simply clone the system from the 120 GB disk to the 200 GB disk. You can do that with utilities such as Carbon Copy Cloner.

T510 Suddenly Restarting/Rebooting while on battery power.

My 1 year old T510 suffers from sudden restarts.
When the notebook is booting up and Windows is loading, the screen will suddenly go black and then restart itself a couple of seconds later. This happens at different times during the process, sometimes while the screen is still black with the animated windows logo and sometimes when it is on the desktop and the system is 99% finished loading.
When connected to the AC power, the issue does not occur.
The one and only way I can stop it from occurring while using battery power is by running windows in safe mode.
Because of this I was hoping it would be a windows/driver related issue however...
I have two hard drives with a different operating system on both. One has Windows 7 and the other Linux Mint. They both suffer the same restarting issue on power up (using the battery as power source). They can both run without a problem using AC wall power.
When the problem occurs don’t get a blue screen and have unchecked the 'Automatic restart' option in case I was missing it.
I am at a loss as to what could be causing it.
Thank you to anyone who can give me some advice on this.

That does nothing for your battery. Removing the battery when not in use (for long periods of time) only helped increase the life of the older NiMH and NiCAD batterys that are no longer used in laptops. That was due to those batteries having cell memory. LiION batteries do not have cell memory, they have charge/discharge cycles.
Humid air promotes discharge into the air, and higher temperatures increase reaction speed. So, all in all, there should be an effect, but how effective it is is dependent on how long you plan to store your battery. Overnight shouldn't be anything significant, but since it's usually fairly easy to find a cool and dry place, you might as well.

When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds. While in auto-lock it is using battery power and will do so until the battery is drained. Whats wrong?

- Try a reset. Nothing is lost:
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Connect the iPod to your computer and try to restore via iTunes. Try placing in Recovery mode if necessary to restore.
- If you can't turn the iPod completely off, let the batter fully drain. After charging for at lerast anhour try again
- If still not successful time for an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I have now been able to get the "Wireless Zero Configuration" started automatically but I must still open the wireless "properties" window and check the "Use windows to configure..." box to get a list of wireless connections. My wireless network will then connect automatically after that. Still a hassle but much better.

I had something similar with 9i a long time ago. I was just using it locally, but it repeatedly kept trying to access the internet, but was blocked, so it kept retrying and writing to the alert log until it grew so big that it filled the hard drive. You might check your files and see exactly what is growing, check your alert log, then deal with the problem, by either disabling something or granting access or whatever is appropriate.

Many of my System Preferences will no longer work after installing Mountain Lion. Software update, startup disk, iCloud, etc. no longer will launch. I keep getting a drop down window saying I must restart system preferences in order to use. No go!

Many of my System Preferences will no longer work after installing Mountain Lion. Software Update, Startup Disk, iCloud, Time Machine, Notifications, etc. no longer will launch even though they do show their icons in the system preferences window. I keep getting a drop down window saying I must restart system preferences in order to use with a "Cancel" or "OK" choice. After I click on "OK" the window just keeps reappearing with the same choices and the pane I wish to use still remains inoperative. Third party preference panes DO work.
Reinstalling OSX Mountain Lion did not help. Neither did throwing away preferences.plist.

Hi Jeff,
Tried to reply with my iPhone but not easy! Anyway, back on the laptop now. Yes the crash was bad but Tek support at Prism Sound was really good. In the end I rebuilt the whole system on a new disk which took a couple of days with all the plugins, softsynths etc.... but there seemed to be no alternative in my case, and this was agreed with Prism sound as being the only alternative left to me. I still don't really know what caused the crash but ML and Orpheus are both working fine now. Let's face it, you'll have to update at sometime..maybe best to pick some time between projects On balance, I suspect that my problems were unique to my system and that your installation will go ok.
Hope it goes well,
Rick

Software Update: Java for OS X 2013-002 1.0
This update, upon booting, has caused my disk space to fill up and my system freezes up. The same happens to my coworker's computer. We both watch the remaining disk space decrease and the "spinning rainbow appears" and we must restart. What do we do?

First, empty the Trash if you haven't already done so.
Use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

Must restart system problems! D:

When I double click iTunes it says please wait while windows configues Itunes. Then it says you must restart your system for the configuration changes made to Itunes to take effect. Click yes to restart now or No to manually restart later. And the thing is I restarted it like 3 times already and it still pop's up. Help please!! D:

I've got to say as someone who has recently abandoned iTunes for Pandora.com that I am terribly annoyed with iTunes. Since updating to version 8, every time I start iTunes it reports that Windows is configuring iTunes, and then it tells me that I must restart my computer for the configuration changes made to take effect.
Forgive me Apple, but get your **** together with iTunes. While writing this message I have been interrupted 6 times by iTunes popping up asking me for something else to deal with.
Were it not for my iPhone, I'd never use iTunes again. The amount of time we waste these days waiting for software updates is borderline ludicrous. If it aint broke, don't fix it. If it is broke, don't sell it.

Synopsis
Problem: Endless Black Box "You Must Restart You Computer..." loop
Cause: Printing certain documents (so far one specific pdf file and a text file) through the wireless network at school initiates the problem and then all wireless networks perpetuate the problem thereafter
Steps Taken: Unplugged wireless network - this allows me to log in
-Warning box about fatal crash appears but "Send Report" does not produce any data
-Restarting wireless after login causes no problems
-Waking computer from sleep with wireless enabled causes black box to reappear
-Permissions repair did not resolve anything
-A complete reinstall solved everything until the other day when printing initiated the problem again, after having successfully printed numerous documents wirelessly over the past month
Other strange things my computer does:
-Makes very quite chirping sound with every key stroke (except arrows)
-Usually sits at the grey startup screen with the spinning wheel for a long time and then speeds through login process
-Only restarts successfully every second time after a hard-restart (the first time it just sits there spinning endlessly)
More Details
Problem: Black box appears notifying me "You need to restart your computer" (Kernel panic I believe?) I restart my computer once, and it sits forever at the grey screen with the little wheel spinning. I hard-restart my computer a second time and it logs me in and then the black box reappears... and then the whole process starts over again..
Circumstances: I had this exact same problem occur about a month ago and it happened again under the exact same circumstances. I recently installed a Korean wireless router, some other foreigner had left behind, in my school here in Korea. The first time it happened I was trying to print PDF document wirelessly from my classroom and the black box appeared. Then the whole endless loop began...
That night I tried to fix the problem at home. I was able to log into safe mode but the endless loop persisted when I tried a normal log in normally again. I finally did a reinstall from my external drive using the most up to date image I had created with Carbon Copy Cloner.
The following day I went to school and couldn't resist trying to reprint the suspect document. My freshly installed computer crashed and I was ****** at myself for experimenting so early in the day. Then I tried unplugging the wireless router and restarting and it worked! Then I plugged the router back in and everything was running smoothly again.
Now I have a new problem. If my computer wakes from her sleep with the wireless enabled I get the black box both at school and at home. I'd really like to avoid doing another reinstall... please help!
Thanks in advance!

Hey Rich,
Think my computer healed herself while I was away this weekend
What I am wondering is if
a Safe Boot will always get you logged in when the
other problems are occurring.
This question prompted me to try starting up in safe mode. I wanted to make sure the problem still persisted so I:
1. Plugged in ethernet cable
2. Turned on Airport
3. Ensured WAN was functioning
4. Shut Down my computer with just like I used to, with all network connections enabled
5. Power ON -> Flawless start up, no black box!
6. Put computer to sleep -> Woke up -> No black box!
Weird eh?
So the only way I can answer your question is based on previous experience. Logging in using safe mode did work the three or four times I used it the first time this problem occurred.
I did nothing to my computer since this error, no updates, no permissions repairs and no sudo daily, weekly, monthly house keeping. When classes were finished Friday night, I came home, put my computer to sleep with Airport off and ethernet unplugged and the following morning I shut her down, hid her in my sock drawer, and left for the weekend!
My only explanation is that somehow reconnecting to the wireless network at school allowed my computer to resolve unresolved issue it was having with that network, the same network that instigated the problem. That's my best guess.
Thanks for taking the time to try and help me out with this issue. The clarification you sought definitely helped us get a more refined picture of the problem. I'm sure this issue will rear its ugly head again in the near future... that is, unless you or anyone else have some ideas about what I could do to prevent this from happening again.

FU,
Here's the info you wanted:
-Only restarts successfully every second time after a hard-restart (the first time it just sits there spinning endlessly)
This might indicate a dying backup battery (the one that keeps your PRAM healthy)
My PowerBook isn't even a year old yet, could it be that my battery has died this quickly? Hmmm, another thing I have experienced is that my Mac wont wake from sleeping if I have let the power get so low that she has been forced to sleep.
1. "10 minutes of battery power remaining" box appears
2. Battery depletes and computer enters sleep mode by default
3. I go home and plug computer into power adaptor
4. Computer fails to wake up no matter how long I wait -->power adaptor light does indicate the battery is charging
5. I am forced to unplug my computer, remove the battery and hold down the power switch.
6. Power on -> Date and time settings have changed and need to be set again
Does this sound like the symptom of a low backup battery?
make sure that "Set time & date automatically" in the Date & Time System >Preferences is unchecked.
I've never tried this so I'll give it a shot and see if performance improves.
now it seems almost obvious: 99% looks like a network fault and nothing >to do with your Tiger installation...
Perhaps, I'm no networking specialist, but I have flawless network performance until printing some random document at school over wireless triggers the whole series of events I mentioned above. My home router has never triggered this problem... although I have never tried to print wirelessly at home because I have no printer.
1) how big is your network? (how many wireless and how many wired Macs >access your Router)
At Home: Very small, 1 PowerBook 64 and one iBook G3
At School: Small: Two Windows machines and my PowerBook G4. Wireless box is plugged into the existing router that was there. I have windows printer sharing checked in the "sharing" section of "system prefs"
2) make/model of your router
D-Link DI-624 (Home)
Some crazy old dilapidated korean box (at school)
3) how do you configure your router (via the browser (Safari) or via a >utility/application provided by the vendor)?
I believe I configure it manually... I access the router via web browser and configure my settings
4) make sure DHCP is set to Off/Disabled and set your IPs for both your >Macs and the Router manually
Check, Check
5) If you're familiar with network settings like hosts file, post back your >configuration / make sure your IP addresses are assigned correctly
Not familiar
btw your PowerBook has an AirPort Extreme card or a 3rd party Wireless card?
AirPort Extreme card
Thanks for trying to help FU, hope this information helps you.

"Must Restart Computer?"

Last night I was on my iBook G4. Suddenly, a transparent grey box appeared and in 4 or 5 different languages (freezes up the whole system), it said that I must restart the computer by holding down the power button for a few seconds. I did that.
When I powered back up, a white screen appeared instructing me to either type "Shut-down" or something else that I can't remember at this time and then to hit RETURN.
Now, the computer won't even turn on! I tried removing the battery and when I try to start up again, I do hear the "turn on sound", but the desktop only displays for a few seconds before that grey box appears again telling me to restart.
So now after removing the battery a few things usually happen:
1. I can't start the computer at all
2. The computer turns on, but only for a few seconds before the bos appears
3. I hear the "turn on sound", but nothing appears on the screen.
Anyone out there have any idea what this is and how to fix it?
Any help is GREATLY APPRECIATED!

stones3131, Welcome to the discussion area!
FYI, this area is for the iBook G3 clamshell.
Since you have an iBook G4 you will probably want to post future questions in the iBook G4 discussion area.

Got Black "You must Restart" screen, won't boot after. only restart screen!

I was browsing craigslist when i got the slow creeping down "You must restart blah blah blah screen..."
After obliging the machine's wish and restarting, it started to boot as normal. After an unusually long boot cycle, i got the same Restart screen. I removed the battery and reset power management because of a post that I found with a similar problem. After that, it goes through the boot system and then just shuts down.
It just continually does the same thing. I believe i left my install discs at work, so am working without them.
I logged in to single user mode and ran fsck -fy , and found it to come back with this result:

anyone know what the **** is going on??
I can't run diskutil in single user and verbose shuts down when trying to boot.

Not bickering at all. Are all discussions "bickering"?
Topher, let me get this straight. How does one determine something is wrong? DU? DW? Other Utilities? What if, after an A&I, these Utilities show nothing wrong? Still recommend an Erase and Install?
This is like the "permissions" debates of yesteryear. My analogy was and is the same. I keep an elephant stone in my house. It wards off elephants. Not one elephant since I bought that stone.
A lot of people around here seem to have this type of thinking as regards someone else's data, time, and effort. It's not that complicated.

Hi
My MacBook Pro has been running out of battery power before the memory-saving sleep mode kicks in, so it dies with a little click of the HD. It's not a hibernation state as when I reattach the power supply it boots up a new session.
I've noticed this since upgrading to Snow Leopard last year, but put it down to an old battery that had 45% charge and wasn't powering the MBP properly. I now have a replacement A1175 5600mAh battery which is giving me 2-3hrs usage (which I'm pleased at), but now it still dies before sleeping!
I have tried to cycle the new battery, but can't. I have reset the SMC several times, with no effect.
I used to cycle the battery every week or two, running it down until it would no longer wake from sleep, recharge overnight etc, but now I can't do this because it will die before sleeping!
I've read quite a few articles over the net about this issue, but there seems like no cure. It's really annoying me now as I frequently work on the move and a dying MBP could potentially be disastrous.
Can anyone shed some light on this issue? Is there something I haven't tried yet? I think it's a late '06 MBP.

If you are not getting a warning, then there is something amiss with your battery. If a SMC reset and calibration does not fix the problem, then you may need to make an appointment at the genius bar and arrange to have your battery tested.
My old battery started doing the same thing--shutting down without warning. I replaced it, and the replacement battery started doing the exact same thing. I then returned the replacement, and the next replacement battery behaves in a normal fashion.
My first battery was worn out. My second battery was defective. My third battery is good.
Your battery should still be under warranty. Go back to where you got it and show them what it is doing and see if you can get a replacement.
Good luck!

Mac Book Pro Shuts down on Battery Power

First, I apologize to everyone for asking this question yet again. I have gone through the previous posts and I am still at a loss. So thank you for your patience and help.
When I run my MacBook pro on battery power it will run for around 15 - 20 minutes... then just be dead. No low battery warning. No shut down. Just poof and gone.
I have looked at my power settings to see if my battery is bad. But I don't have a Status indicator in there. I see This:

I have also looked at the directions on http://support.apple.com/kb/ht1490 about how to calibrate my battery. It says:
" 1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again."
Only I have a problem withe step 3 and 4. I don't get the warning, and it doesn't go to sleep. So, I don't think any calibration is working.
Do I need a new battery? Should I just buy one? This computer is WAY out of warranty and I never purchased and apple care plan for it.
Again, than you for any and all advice on what I may need to do.

I think it's time to buy a new battery

I just replaced the hard drive on my macbook pro, reformatted new hard drive and copied over a backup from time machine now I have a kernel panic message (you must restart) - what do I do now?

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents – the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
