My Xserve does not wake up every Saturday from a cold start / cold boot up.

Hello, everyone,
This is my first time using this Apple Discussions Forum here and so hope any expert out there who can solve my problem, I'd deeply appreciated. Basically the problem is like this.
I configured Xserve to
wake up 8:50 am wake up every morning.
shut down system 1:00 am every morning.
There are two places to be configured here:
1. System Preferences' Energy Saver
2. Workgroup Manager>Computer List>Preferences> Schedules>Mac OS X Server.
The time schedules in those two places are ensured to be at the same setting.
(does anyone know which is the main one?)
Furthermore,
I have a clock timer set to 2:00 am to shut down the main power supply to the Xserve. And so,
Power Supply timer provides power to Xserve:
8:40 am every morning (before scheduled Xserve waking up time, 8:50 am)
Power supply cut down the power to Xserve:
2:00 am every morning (after scheduled Xserve shutting down time, 1:00 am)
Why am I doing this? Because I think it is good for Xserve's power supply fan. If I let Xserve's power supply run 24/7 for years, the motor is wearing down soon. It also saves some energy for me.
Normally the power supply would first provides the power to Xserve before Xserve would boot up as scheduled.
Now, this setting works pretty well for me for months until recently.
My Xserve will not boot up every Saturday morning as scheduled. I cannot figure out why it does this weird behavior.
I tried to search forums and google many many places, and find no solution.
Here are a list of things I have tried:
I changed 2 new PRAM battery twice in one month.
I have tried to reset SMC.
I have tried to reset PRAM.
I tried to reset PRAM before SMC reset. I also tried to reset SMC before PRAM reset.
Worse yet, on Saturday morning, Xserve is like in a deep coma, I tried to remotely boot it up by LOM, it does not even respond to my LOM waking up call. It is like a naughty kid refusing to wake up in the Saturday morning. The only way to wake it up is that I I have to take a long walk and physically go to my Xserve and hold the power button for 5 seconds and press it again and so it wakes up. Note that if I just press the power button once, it does not boot up neither. Why?
Then the next day, it is normal again for another 6 days until next Saturday. I could not figure out why it does this. Why just Saturday? Why not Sunday or any other day between Monday to Friday?
Funny and strange behavior.
The problem is periodic and so I believe it has something to do with the software and/or the PRAM caching the alarm time, which may influence the SMC setting.
Note: the Apple website says SMC controls the waking time while Apple manual also says PRAM is responsible for alarm clock.
I would normally
shut down system
unplug the cable
hold the power button for 5 seconds and let it go
plug back the power cable.
Xserve should either boot up by itself or stay cold for me to boot up.
note: the manual just say unplug the cable for 5 sec but did not say hold the power button for 5 second, and I think that is wrong; you have indeed have to hold the power button for 5 seconds as the Apple website said. Otherwise when I cut down power supply every day, my SMC is reset by itself every day.
I have a voltage regulator before my Xserve's power supply and so the voltage is very stable.
Any Xserve experts out there has the same problem like I do??

Hi, MrHoffman , I couldn't agree more with your view point. Xserve not only reacts poorly to sudden power shortage, its HDDs may also get hurt during sudden power removal. Therefore, I was extremely careful when resetting SMC. Bad SMC procedure can hurt HDD.
MrHoffman , my problem is not totally solved and you knew I will come back, right? I do accidentally find your blog. Is the site yours?
http://labs.hoffmanlabs.com/node/976
Your blog and threads from here has inspired me to investigate in the direction on LOM issue. Thank you.

I've come to narrow down the problem and suspect the root cause is LOM bug. Basically this is what happens in the last 4 days.
After nearly 3 weeks of monitoring my Xserve, it was running perfectly normal until 4 days ago. Suddenly, my Xserve fails to wake up for 4 days in a row. I almost made it---a perfect run for 1 month without ever having to reset SMC once! This time, the failed waking-up event took place during normal weekdays. So it is still a mystery to me that why my Xserve previously fails to wake up only on Saturday (perhaps, hackers prefer Saturday because that's when they are free?---just kidding). However, at least I now know the problem can take place at anytime.
Maybe I should first list my Xserve's specification.
Xserve Late 2006 Model
2.0 GHz Dual-Core Intel Xeon
8G RAM
Mac OS X Leopard Server 10.5.8 (Build 9L34)
Boot ROM: XS11.0080.B01
LOM version: 1.2.8
I am only using en0 for both LAN and LOM.
So since I was not able to wake up my Xserve remotely by LOM, it is intuitive to check Server Monitor on Xserve side.
On my Xserve side, I had
Name: Nothing (it was localhost)
IP Address: 127.0.0.1
Status Summary: Software is not installed properly on server.
At this point, I was wondering where did my Status Summary go? So as an incentive move, I delete the 127.0.0.1 from Server Monitor list and go to >Server Monitor>Server>Configure Local Machine, trying to re-add the localhost server back to Server Monitor list. Then it is when all of the troubles occur.
The Server Monitor simply hangs there. When check Finder>Force Quit Applications, I see Server Monitor (not responding).
So I was questioning myself that if this failed waking-up event is a software issue or a hardware sensor issue. Before answering to this question, as a good habit, let me post my log file.

Home button does not wake up iPod Touch

Hey all,
After the iPod screen turns off automatically after the preset idle time, pressing the "Home" button does not wake the device up from the first press; on some occasions it has to be pressed twice before the "Slide to unlock" screen appears.
This is intermittent and I can't pin down how to accurately reproduce the issue, but it seems to happen randomly. I have never experienced an issue where the "Home" button didn't work when pressed during normal operation, so I don't think it is a hardware issue with the button itself. Note that I had this issue before updating the device to 3.1.2 as well.
I have auto-lock set to 3 minutes, with Passcode Lock on.
The device is the 32GB model MC008C, updated with the latest 3.1.2 (7D11) OS.
Cheers

sorry to reply and intrude here but i cannot for the love of god find he new thread button. (maybe a mod will move me please)
I recently restored my iPod touch and i didn't really watch the restore. I know the loading bar on ipod was nearly at end. Anyways, 10-15mins later i go to use my ipod and clicking the home button nothing displays.
I then try to turn on, yet nothing. So googling, i left the battery to completely drain if there is any.
I plug my ipod into my computer and nopthing happens, it does not wake up(turn on) or even charge. I have tried an Iphone wall charger, yet no response from my ipod touch as well.
So i kept googling and i found out about some DFU mode, there was lots of different combinations on the web, i tried them all, yet my ipod does not respon. No noises, notifications or anything in itunes(if itunes closed, does not open up!)
It has now been a good few days since it stopped working, and i cannot think is there anymore to do. It is still in warranty for a few months.
Only problem is, i do not think i;m entitled to phone support, and the nearest genius for me is hours away.
PS: my iPod touch was restored to version 3.2 (latest version if thats wrong <!-- )
I have itunes 9.1
Running windows 7 rc
I have tried my ipod also on the following:
My dual boot vista, another computer with vista and a Mac Pro.
Can anyone suggest anything or help me please?
Thanks in advance,
Malcom

My iphone 4 switches off unexpectedly and does not charge properly every time

My iphone 4 turns off unexpectedly and does not charge properly every time. Can anyone help

Hey bigstu29,
Thanks for the question. To completely isolate the issue, you may want to follow these steps:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
               - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
               - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
               - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
               - If the display turns on, go to step 4.
               - If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

MBP does not wake after closing lid

MBP does not wake a when I open the lid,

I have the same problem.
In Leopard I could hit esc a couple of times and it would restore the display. In Lion no matter what I try nothing works except a total power down and reboot.
I can hear the hard drive searching around but no screen.

Hmm... I've had this macbook for a while now (?? a year maybe ??) and about 2 months ago I started having this exact issue, close lid to sleep returning it would not wake and a hard reset (hold power for 5+ seconds) is required.
I too discovered such links as this and also the older (also unanswered):
http://discussions.info.apple.com/message.jspa?messageID=8690782
But as others have said there doesn't appear to be a solution?
RESET THE SMC (http://support.apple.com/kb/HT3964) does appear to work, however the issue returns again after a few days or weeks... I cannot find anything that guarantees to return the issue it just starts happening again after a while.
The battery appears to be in okay condition, although I think it might run down a little faster now days than when I first bought it, but I assume this is to be expected.
I also had suffered from what sounds like an issue with wifi weirdness - signal would drop to 0% suddenly, no longer "see" the wifi hub that it has been using forever (although it still, randomly, sees other nearby hubs) for no apparent reason, and that kind of thing - all these times the only solutions that have worked have been to stuff around with the wifi hub turing off extas, flipping from "Auto" to a specific Number (1 to 13) and turning on (OR OFF!) Mixed B/G to just B OR G... very strange... and random.
The only things I've changed recently are, upgraded to snow leopard (from leopard) and got an external display. But I cannot say if the incidents coincided or not, as I didn't realise the sleep/wake issue was an issue for a while, as the first few times I just thougth "Oh, something weirds happened... Reset..." and didnt' really think too much about it until it happened for the 3rd or 4th time and I could see there was a pattern...
The external monitor via minidisplay port adaptor i got from teh apple store.
I don't use it with the machine closed or external keyboard/mouse, although I've heard you can do this, I use the monitor as a secondary display when I'm at the desk, the rest of the time I just use it as I have always done.
I would love to see a solution to this, I guess I could try warranty, but I dunno if the issue is warranty "level"...?

My macbook pro goes to sleep by it does not wake up. I have to restart it. I had recently to change the board in the attached Thunderbolt display.

my macbook pro goes to sleep by it does not wake up afterwards. I have to restart it. I had recently to change the board in the attached Thunderbolt display, because I noticed that the same problem arose when the display was attached.
Now with the new board, it can't be the display's fault. I hope it is not macbook pro's main board fault. Maybe hasthe notebook board been damaged by the faulty display?
To bring my MacBook Pro to service will slow down my work. This is why I am posting this message, in the hope to be able to run a diagnostic test myself.
Thanks a lot, in advance.

Hello Aminetti,
It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
Reset NVRAM/PRAM
Test with external devices disconnected
Try Safe Mode
Try another user account
Thank you for using Apple Support Communities.
All the best,

After Thunderbolt Firmware upgrade display in target mode does not wake up from screensaver

Hi!
I have a MacBook Pro 2011 (Snow Leopard) connected to an iMac 2011 (Lion) via Thunderbolt. The iMac runs in display target mode.
Last night I update the Thunderbolt firmware on both systems via SW update. Now I have the problem, that the iMac display does not wake up from screensaver mode when I enter the password to unlock the MBP blind (the iMac screen is the main display).
I have to do cmd-F2 twice (do disable and enable) target display mode to get it back to life.
This worked fine before the Thunderbolt updates.
Does anybody else have that problem?
Thanks!
Hank

I have a 2.2Ghz Macbook Core 2 Duo system purchased in December 2007. I have 2GB RAM installed.
My system has developed a weird problem where it won't come out of sleep ... 100% of the time now.
I've tried resetting PRAM/NVRAM, resetting the power module and even reinstalled Leopard. Nothing has helped. I'm at my wit's end.
When I put my system into sleep mode, it goes into sleep mode as you would expect. However, when I wake the system (by opening the lid or pressing any key), the system looks as though it's come out of sleep (ie. there's a picture of desktop) and I can move my mouse but I can't click anything. I can't Cmd-Opt-Esc either. I have to perform a hard-reset at that point.
I have quit all other applications to try to isolate the problem and I'm beginning to think it's either Leopard or my MacBook. Either way, it's annoying as **.
Has anyone come up with a way to fix this? Doesn't seem like I'm the only one.
Thanks,
Chris

Macbook does not wake from sleep properly.

My macbook 2.0ghz core duo, 10.5.6 does not wake form sleep like it should. it behaves similar to when it runs out of battery with a pale screen and a loading bar, like it is restoring the system from the sleep image, although the battery is full. Has anyone else had this problem and been able to sort it out? Perhaps there is something wrong with the battery controller. Any advice appreciated as it is quite annoying.

I am having this same problem. The computer itself is awake, but the display stays blank. I can restart it by pressing the power button then 'R' then 'return'. This just starting happening frequently recently for me. It may be the result of one of the more recent security updates.

TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

10.8.5: External Harddisk does not wake up with iMac after standby

After upgrade my iMac 27 early 2013 to 10.8.5 my external USB 3 harddisk (for TimeMachine Backup) does not wake up when my iMac wakes up from standby. The external disk is unmounted and a error message apears.
I had this problem really really rarely with 10.8.4 but now it is reproducable at any time.
Any hints?
PS: Yes, I have turnes of sleep mode of my external harddard in energy settings.
Thanks for any help...

I had the same problem with Time Machine and solved it by enabling "Enable Power Nap" in Energy Saver:

HT201150 macbook air 11" 2013 does not wake from sleep mode. Any ideas?

Since I have changed my macbook air, I had started to have these issues. This is my third macbook air11" and until this one all was fine.All of a sudden I started to have the sleep/wake problem. Oce the lid is closed, it goes to sleep and does not wake up or the battery needs to be charged pops out and I have to charge for 10 minutes and find out that I already have 80-90% battery power. Also the apps open up, but the windows get lost( mail is open, but no window to read the mails) The genius bar checked the laptop twice and finally changed it , but nothing else changed in my life. All the issues are the same, and even getting worse. Just a minute ago, I even lost the WiFi. "There is no hardware message appeared!! Anyone for any ideas?

You're welcome... here's hoping it's not a hardware issue but this test will elimnate any suspicions.
You could also check the startup disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart

My iMac does not wake from power safe mode

My iMac does not wake from power safe mode when addressed over the network from my Apple TV, until I send a "wake on LAN" command from a utility on my iPad. Is there anyway this can be done directly from Apple TV?

Tons of similar reports all over the web - especially on ATV3 - but no solution, seemingly. Hopefully a software update will fix it one day soon. Sorry.

My Xserve does not wake up every Saturday from a cold start / cold boot up.
