A600 Won't Wake Up - Help!?

I have an ideacentre a600 that I upgraded to Windows 7 Ultimate. Randomly, the computer will just go into sleep/hibernate mode and it won't wake up. I've tried all the usual methods to wake it up, like moving the mouse or hitting keys on the keyboard and nothing is working. I even got creative and tried plugging in a wired mouse to see if the USB ports were asleep to no avail. The only way I can tell the computer is still running is that the touch sensitive controls on the front panel will light up when touched but they don't wake the computer up. I've adjusted all the settings in the computer including the display and power settings and there is nothing there to indicate it should ever go to sleep. It probably happens about once out of every 5 times but it is extremely frustrating because the only way to get it working is to do a hard shutdown on the PC by holding the power button down and then booting back up. Please let me know if anyone else has encountered this or what can be done to fix it.
Thanks,
J

Ops I replied to myself in error.....
Tom:
I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
Then I have to shut it down with the power button and then power it up as a reboot.
Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally. It seems to be a overnight problem.
Am I going to have to shut it down everynight?

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!
Semi-experienced user - Western New York.
System was operating nominally until I opened it from 'sleep' mode after ~1 hour of inactivity.
No idea what's going on. I had just installed a Flash Player update [not an atypical occurrence] at ~6:00 PM this evening, but used the system without incident after that. Re-Start attempt does not appear to succeed, the circular pre-OS icon never clears and displays the authorization screen.
Anyone with an idea how to help would be greatly appreciated. We have so much personal and business data on this machine!!!
Thanks!
Jim F.

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
The fact that you're worried about the data implies that you have no backups, or that you don't have confidence in your backups. Your first priority must be to back up all the data you intend to keep. Ask if you need guidance.

Help! my computer won't wake up from standby!

This problem just started. If I put it into standby, or if it goes into standby, it either takes forever to wake up, or it won't wake up and I have to reboot. It used to wake up immediately if I hit any key. Now I've tried keys, mouse clicks, Ctrl-Alt-Delete, Esc, pushing the On button. Sometimes it will f-i-n-a-l-l-y give me the login page. Sometimes it won't.
Thanks for any help!

Hey Zyzx,
I have seen this type of condition before in a USB connected printer. How do you have the printer connected to the Windows XP Home Edition desktop PC? (USB or Network connected)
If the printer is connected by a USB cable, then you may try a different USB port on the PC and uninstalling/re-installing the USB Controller on the PC.
To perform the uninstall/re-install of the USB controll follow the steps listed below.
Boot into Safe Mode on the PC
Click on the Start menu of the PC
Right Click on My Computer
Select Manage out of the list
Select Device Manager in the list on the left
Right click on the section titled "Universal Serial Bus controllers" and select Properties
Uninstall the section and restart the PC to perform the re-install
I will look into this issue more for you and get back with you.

HELP! My Mac won`t wake up after installing Windows and Bootcamp

Hello,
I posted a message in another discussion earlier but I guess it is best to open a new discussion.
I upgraded to mac Leopard today (on a new 24 inch imac) and installed bootcamp.
In bootcamp I chose the 32GB FAT partition for windows, and everything worked fine until I had to choose the partition to install windows, where I could only choose a 115 GB (or so) partition. Fearing I'd mess up my Mac partition, I quit the windows installer (following the instructions in the installer) and since this, my mac wakes up with the mac sound and the screen remains blank. No matter what keys I push durin power up, or the installation CDs I insert, my Mac won't wake up!
Does anyone know what to do?
Is there a way to recover the master boot (or whatever it is called in mac?)
Thanks
Thanks!

I have had the same issue...
I just purchased my 20" iMac less than one week ago. I tried running boot camp and got an was not able to see my bootcamp partition in the windows installer. I quit the installer and now my computer launches into the white screen and will not progress further. I have tried various methods of recovery but to no avail. Here is a list:
_Using the iMac OSX Leopard installer disk_
• insert disk into iMac slot and boot pressing "c" - result = white screen
• insert disk into iMac slot and boot pressing "x" - result = white screen
• insert disk into iMac slot and boot pressing "option' - result = white screen w/ mouse pointer
• insert disk into Power Mac G4 in target mode and boot pressing "c" - result = white screen
• insert disk into Power Mac G4 in target mode and boot pressing "x" - result = white screen
• insert disk into Power Mac G4 in target mode and boot pressing "option' - result = white screen w/ mouse pointer
• trying to boot Intel iMac in Target mode pressing "t" - result = white screen
_Using General Purpose Leopard Disk_
Same results as above.
My question is there any way to get this system to recognize a boot disk or see any boot partition outside itself?
All of the above methods were done with the power cable being unplugged and plugged back in and being all sorts of careful. I have had the CAT-5 cable out of the system during whole process.
Is there some triple secret trick that I don't know about?
Note - I have worked on and serviced video and graphics systems on Mac 8200's on up (and others) for over 12 years. So I am not a babe in the woods. My guess here is that Boot Camp is doing something to the firmware and it is toast.

Display won't wake up

It's a brand new notebook.I've done nothing on it, other than installing Windows updates and creating recovery disks.I set the "Turn off display after" option to 1Minute.IMPORTANT: I set display brightness all the way to zero, the lowest setting possible, using either the keyboard keys, or the brightness option in Windows.Leave the notebook idle for a minute, the display sleeps like it should (the notebook is set to sleep after 30 minutes, it's only the display that sleeps, the notebook is still awake).Move the mouse, press keys on the keyboard, the screen does not come back up. The computer is still up and running-i can toggle keyboard backlight On/Off using the keys, but the display won't wake up.Press the "Brightness +" button on the keyboard, the display wakes up. This is the only way to wake it up. The other option is to press and hold the power button, force a shut down, and start the computer again.This happens ONLY when "brightess" is set to the lowest level. If brightness is set to even one level above the lowest, the issue cannot be reproduced. Moving the mouse or pressing any key on the keyboard will wake the display up in this situation.Both Intel HD graphics 5500 and GTX 850M drivers are up to date.BIOS is up to date as well.Battery/ Plugged in does not make a difference. If the display brightness is set to lowest, the screen will ALWAYS fail to wake up, irrespective of which power source is in use. What do I do? Please don't tell me it's a minor problem and I have to live with it.There are so many minor problems with this notebook, and all these are adding up to make it a total piece of cr.. My almost 5 years old probook with a second generation core i3 CPU and no discrete GPU, is better than this brand new 5th generation core i7+GeForce GTX notebook. I'm beginning to regret this purchase. I should have gotten another probook. Thought the Envy offers a better "bang for the buck", and now i think this was a huge mistake. Anyway, any idea how i can get this fixed? Looks like a driver problem right? Or is this a hardware problem? Can someone with an Envy notebook try this out and tell me if the issue can be reproduced on their rig? It can't be reproduced on my Probook.Thanks.

Thanks for your reply Avenger Well, I called up HP tech support.The lady took remote control of my notebook and tried numerous things in the registry (regedit).But the issue could not be solved. She then arranged for an on-site support engineer to visit my house.The Engineer showed up right on the next day, and tried the following:- Updated ALL drivers, even the ones which were already up to date!Checked with my desktop monitor, the issue cannot be reproduced on the external monitor- the external monitor will wake up on moving the mouse, but the notebook monitor stayed dim (no backlight).Opened the laptop, took out the display cable, cleaned it with some solution he had, put everything back together- issue not resolved, external monitor wakes up but notebook monitor stayes dimmed. This is not the only problem I was having with the notebook, the other problems are:Battery would stop charging when the notebook is switched OFF, and the charger is turned ON and OFF a couple of times.The battery lock doesn't "click" in place, it slides automatically to the "unlock" position, it's loose.There's a dead pixel on the display. He offered me two choices: 1> Replace motherboard (to solve battery not charging issue), replace chassis (to solve the battery lock issue), and replace display panel (to solve the dim display + dead pixel issue). =======OR======= 2> Return the whole notebook back to HP, and get a new notebook (same model) in exchange. I picked option 2. We shared a cup of coffee, and the tech left (he was very nice and friendly). The next day, I got an email from HP, with a PDF attachment, asking me to take my laptop, along with a hard copy of the email, and payment invoice, to the HP store. HP store took my computer back, but they didn't have a replacement ready, they asked me to come after 7 days to pick up a new notebook (same model). I really loved my Envy. It's a very nice looking laptop. Hope the replacement I get won't have these weird issues. I'll update the thread when I get the replacement. Thanks for your help

MacMini (late 2012) ML 10.8.3 won't wake up

Hello,
My MacMini running ML 10.8.3 will go into sleep after some period of inactivity, and won't wake up (typically happens overnight, but not only). I have to shut down using the power button and turn on again.
I've already reset the PRAM, repaired permissions, ect...

Bootcamp: XP won't wake after standby

2010 Macbook Pro 13, OS X 10.6.3, XP Home SP 3. Install went fine, everything works. However, if I close my lid while using XP the computer won't wake up again. A hard reboot is required to recover.

Update: I've gone to the XP Software updater and downloaded and installed 72 "urgent" updates and several optional software updates. I'm not sure what was in those updates or why my new XP install was down so many updates but the problem is resolved.
Steps: Start -> Help and Support -> "Keep your computer up to date with Windows Update" I then selected "Custom" and installed everything.

Added second monitor computer won't wake up

I have reviewed several support threads on the subject of a 2008 Mac Pro not waking up after it goes to sleep. I have a 2008 mac pro that was working flawlessly with a 26 inch asus monitor. My bluetooth mouse and keyboard would wake it up instantly. I decided to add a second monitor, a 27 inch planar.
I had the mac set up to save power and after just five minutes of non-use it would go to sleep. My wife asked me if I would keep it on longer so she could watch the pictures that show up through the screen saver so I set it to 15 minutes and then it goes to sleep. Now though, if it goes to sleep it won't wake up and remote connections from an imac fail to awaken it as well. I am forced to hold down the power button to shut it down. I have tried the startup where I hold down command option p r but I can't get it to sound a second chime whether I start after the first chime or before the gray screen appears. After trying this every other restart does not work, the fans turn on but nothing else happens. It is quite odd. I am at my witts end. I suppose the proper course of action is to disconnect the second monitor and see if it wakes up, but I am hoping before I do that that someone might weigh in on the issue and solve it. I guess I should also try a usb keyboard as well. Thanks in advance for reading this and I hope you can help me out with this. John

Ok, here is where I am at. I reseated the two dimms. They are now showing up. I still can't get a PRAM reset to work and I have not obtained a USB keyboard yet. I reset the PRAM on my imac with a bluetooth keyboard and it worked so I believe I am doing it properly. I reset smc via following directions on an Apple page. I am hooking up the second monitor now and will see how it goes. I will keep you posted. Thank you.

Imac won't wake up since 10.4.7 update

Hello! I have a 17" imac g5 (purchased in 12/05) that will NOT wake up from sleep now since I have done the OS X 10.4.7 update. I have to hold the on/off button for at least 5 seconds and by the 2nd or 3rd time it will finally come on. Any ideas?? The only peripheal I have is a card reader. It does it with that unplugged. I also fixed disk permissions, still won't wake up. Since I am still relatively new to Mac, I need detailed instructions. Thank you so much in advance!!

Hello,
At this point, it would seem that you are down to two last options:
1) Re-install OS X from your original Restore disks.
2) take it in for repair and see if it's a hardware problem.
I think you have the last version of the iMac G5 (the one with the iSight). If so, you are still under warranty since those came out around November or December. So, you should still be in your first year (a 3 or 4 months left).
I think at this point, it would be best to do two things:
1) Run the hardware test that came with your computer. See if that finds a problem.
If it does, we'll stop there, and let you take it in for servicing.
This should be on one of your restore disks. It will say Apple Hardware Test on the disk somewhere (smaller print). And, provide directions for starting the test on your particular system.
Now, once you are in the test, run both the standard and extended tests. See if either finds a problem. This could take a couple of hours.
Let me know what it says.
2) Now, if it doesn't find any problems, then I would propose that you re-install OS X from scratch.
I would first copy any important information to an external drive or disk.
If you have an external hard drive, you could make a full backup of your entire hard drive using a program such as Carbon Copy Cloner:
http://www.bombich.com/software/ccc.html
This program can be used to create an exact clone of your main hard drive.
So, it is a bootable backup that can be used to put your entire system back exactly as it was at the time of the backup.
This means that if something happens, you can boot from your external drive, and resume normal work. Or, you can boot from the external drive and run the program again to restore your computer to match the backup.
This backup is an exact clone of your entire installation, so it is readable by another machine.
It works great, and I've never had a problem with it.
But, I use the "Clone" feature.
This has the advantage of being able to restore quickly, and return back to the exact point you were at when you backed-up.
In your situation, we would use this backup for two purposes. First, it ensures that all your important information is backed-up. Second, it means that if your new installation doesn't fix the problem, you could just revert back to this installation and everything would be like it was.
Now, if you don't have an external drive, then just backup your important files (e-mails, documents, downloads, anything of importance to you) to another disk (CD-R or DVD-R, etc.).
Make sure you get the 10.4.7 Combo Update stored somewhere so you can update again without downloading it.
Once you have verified that everything you want is safely stored on another disk or drive, then you could proceed with the re-install.
Make sure you disconnect any external drives (FireWire, USB) and other accessories before re-installing. Just keep your keyboard and mouse connected.
You can install OS X by booting from your Restore disks. Insert the disk, and restart while holding down the letter C on your keyboard until it finishes booting from the restore disk.
Once started-up, I would personally recommend using the "Erase and Install" option. This will give you a completely fresh installation without any of your old bugs getting carried-over.
The "Archive and Install" will basically install a fresh copy of your OS X while preserving your settings and installed software.
Here's a good article summarizing your options and how each works:
http://docs.info.apple.com/article.html?artnum=301270
The problem with Archive and Install is that sometimes problematic settings will survive using this method.
So, for best results, use the Erase and Install. Since you already have everything copied to another disk, this shouldn't be a problem.
Once the fresh installation is done, then see how your system behaves.
If everything is fine, then immediately install the 10.4.7 Combo Update.
Now, repair permissions.
See how things are now.
If everything is fine, then go ahead and setup your e-mail, programs etc.
Copy your data and files back, and resume operations
3) Now, if things still don't work right, then call your service shop and arrange for warranty repair.
It is a pain to go through all these steps. But, the service shop will blame software first unless the hardware test reveals a problem.
So, by doing a fresh install, you beat them to it. You can tell them you have already done that, and know the problem is hardware related.
Anyway, I hope that the re-install isn't needed. But, if it is, then the steps are listed above.
Start with the hardware test and other ideas above first. But, if those don't work or reveal something, then go ahead and re-install and let me know what you find.
Keep me posted on your progress, and let me know what does or doesn't work for you.
I hope this helps.

My ibook won't wake up

I have only had my ibook G4 for a few months and occasionally when I shut it down, it takes a few tries brfore I can get it to turn on. The last time I put it to sleep, it won't wake up. It was over 50% charged before I put it to sleep, but now when I check the battery on the back, only one button flashes?! It seems that when it is sleeping, it is draining the battery or something. I usually get 3.5 hrs or so of use on a charged battery, so I don't think it is a faulty battery. I don't have applecare and my 90 days are up! Does anyone have any suggestions on what this could be?
ibook G4

First of all: Get AppleCare (or a warranty extension from a local Apple dealer)! You can buy it within the first year, it isn't limited to first 90 days. Seriously, if you're not habitually buying a new computer every year or so it's worth it. Notebooks (usually) do get carried around a lot more than desktop pc and bad things happen (e.g. the hard disk in my PowerBook died after a little more than a year—mechanical failure, probably more Seagate's or whomever's fault than Apple's).
How long did leave in sleep mode when it drained the battery? (Yes, it also needs energy in sleep mode so after several hours it will run flat …!
Try resetting the PMU (see here)! (You know it worked when the date is set to 1970 after booting.)
Also, maybe the battery already is damaged after all (something that happens, too—I had one that went from 50% to zero without waring).
With the right energy saving settings, a thoughtful use of screen brightness and all unused network devices (ethernet, wifi eventually and also bluetooth) in my experience an iBook battery should last up to 5 hours (depending on your usage, of course!).
My advice: Try not to let the battery run flat after the initial calibration (see Apples support docs, I'm too lazy to google them up)! You can (re)charge it any time, but letting it run flat will diminish its capacity!! (Works like that with most modern devices with rechargeable batteries (cellphones, iPods etc.). Unfortunately many people still think it's better let them run flat every time like in the old days.)
Mind you, a notebook battery will suffer wear and tear and will need to be replaces at some point …
Hope that helps!

G4 won't wake up or sleep on command

In my search, I only found this problem with powerbooks. I have a G4, and it recently won't wake up when it goes to sleep. I have never been able to put into sleep mode on command since getting Tiger. But it does go into it on it's own when left alone, but it won't wake. I had this happen before and reinstalled everything from system software to all software. It worked for a while, and now I'm having the same problem. I just added the 4.6 update today, and it did not help. Any suggestions? I really really hate to have to reinstall everything so often. I also have problems with the fonts being jarbled up in browsers. Both of these problems happened about the same time.
thanks!

If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following lines:
reset-nvram
press Return on keyboard
set-defaults
press Return
reset-all
press Return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.
Cheers!

WON'T WAKE UP WHEN OPENED DURING SLEEP.

this doesnt happen every time but whenever i close my macbook pro to go to sleep and then open it some time later, the screen stays black and the computer won't wake up. i have to close it multiple times and reopen it before it actually does something. Can anyone help me understand why its doing this?

I think this has something to do with the sleep related loss of keyboard response issue that is plaguing MBP with 10.5.1.
I had it happen to mine last night, it freaked me out so I reinstalled Leopard. Let us see how long until the problem crops up again!

Apple keyboard or mouse won't wake up iMac from sleep.

After I put my iMac to sleep the keyboard or mouse won't wake it up. I have to push the power button to awaken it. Wake from sleep is enabled in bluetooth preferences so that is not the problem. Otherwise keyboard and mouse are working fine. Any help would be appreciated.

Regrettably, I can't offer a solution to the problem stated in the title. Instead, I experience the same problem.
Wireless Mighty Mouse circa 2007
Wireless Apple Keyboard circa 2007
Bluetooth dongle (a bluetooth thingy connected to a USB port)
Things worked fine until an upgrade from Tiger to Snow Leopard. Following the upgrade there were several mouse related issues. Those were resolved. One issue remains: waking by use of mouse or keyboard.
The setup (Same for keyboard and mouse)
System Preferences --- Bluetooth --- Keyboard Connected --- Keyboard Paired. The "Discoverable" box is checked.
Digging deeper
System Preferences --- Bluetooth --- Advanced --- "Allow Bluetooth device to wake this computer" --- This option is unchecked and is greyed out, inaccessible. Two of the other options are checked and available: the options about opening the Bluetooth assistant and the one about prompting incoming audio.
I've searched other posts. However, many of the other posts seem to conflate this Wake/Sleep issue with various connection issues. Thus, the advice given is a bit confusing to this amateur. Might one of you experts have a solution to this annoying little problem?
Thanks for your interest.

MacBook won't "wake up" from sleep mode since downloading Mavericks.

I have a 2008 MacBook and since downloading Mavericks, I've had a lot of issues when the computer is in "sleep mode." There are many times where it won't wake up and just remains a black screen. I'm forced to shut it down and turn it back on. When I do this, I have to login and it reloads everything I had had opened when it was put into sleep mode. Help! Thanks.

I have the same issue with my Macbook Pro 2.4
Have you by any chance installed a new RAM?. I've just added new 8 GB RAMs & I noticed the issue afterwards, but I'm still not sure if it's the cause.
