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.

Computer Won't Wake Up From Standby After Installing 7520 Printer

I installed a new 7520 on my desktop PC (running XP Home). The printer works fine but when the computer goes into sleep mode, I can't wake it up - forcing me to reboot the PC. Sleep mode on the computer worked before the printer install.
If I keep the printer turned off, waking from sleep mode on the computer WILL work properly.
How can i fix this?
This question was solved.

Computer won't wake up from sleep

1 month old pavillion 500-205t, windows 7. I set computer to sleep after 10 minutes and monitor after 5 minutes. It hasn't mattered how long these times have been set for because I have tried other times. Most of the time it wakes with the mouse or the keyboard. Other times, when the white lighted on/off button is on steady and not flashing on and off every 1 or 2 seconds. the computer and monitor will not wake up. This has happened at least 15 times. I have tried loading a cd, pluging a usb tool and different devices all to no avail. I have to hold the on/off button for 3 or 4 seconds to shut down. I have tried hard shutdowns and unplugging computer. I can see a light next to the on/off light working as if it is trying to read something, ie flashing very fast. I've had 4 pavillions and this is a first. Bought through Costco and they don't know what to do. Thanks

Computer won't wake up from sleep mode

Hello I am having an issue with my computer not waking up from sleep mode.
Example:
I walk away from my computer for a certain amout of hours and it goes into sleep mode. I come back and move the mouse or hit any keys on the keyboard; nothing, doesnt come back to life.
I have the latest driver updates, I have tried looking this up but came up with nothing, and also I thought that I set it so it wouldn't go to sleep but don't know if I did it right.
This is my computer:
Laptop Toshiba Qosmio x505-(sorry don't know the exact spec)
Thank you,
Dillan

Dillan
Try resetting the power plans to the default. Enter this at an elevated command prompt.
powercfg -restoredefaultschemes
If you need to repost, look on the Toshiba label on the bottom of your laptop. Gives us the full model name/number like Qosmio X505-Q830, and give us your model's part number like PQX33U-00K00H. As well, please confrim what OS version you're using like Windows 7 64bit.
Let us know what happens. Good luck.
Mike

Pearl 8110 won't wake up from standby

I've had my Pearl 8110 for about a week now and if I leave it on standby overnight it is completely unresponsive in the morning--only replacing the battery forces the phone to restart.
I tried all of the regular solutions:
- holding down the mute key for 30 sec
- holding down power key for 30 sec
- pressing every combination of buttons
I have the latest available device software from my carrier AT&T (4.5.0.110).

I don't see how the battery could be any part of it. If the battery is charged, its charged.
I am not sure that an OS upgrade would help, but it could.

A60 screen won't wake up from Standby

I have my power settings to put the machine into Standby when I close the lid, which it does. However, when I open the lid again, it sounds like it's coming out of Standby (blue power light illuminates, cooling fans start, the HD begins working), but the screen remains black. The only way I can revive it is to shut it down (holding the power button) and restart with the power button.

Looking at the latest BIOS update (1.90) for the A60 series, it corrects the following (among other things):
Change lid switch behavior to "brightness off" instead of "panel off".
Might be the solution to your problem.

Powerbook G4 won't wake up from sleep

My 4 1/2 year old powerbook G4 won't wake up from sleep anymore. After I close the lid, or even manually put it to sleep, I can still hear the HD run. The backlight on the top of the lid never lights up and when I open the lid the blank screen doesn't do anything. The only way for me to work around this issue is to power down the laptop and start it up again. Since I've been having this issue every program that I use take forever to load. The spinning color wheel is the bane of my existence! I tried resetting the PRAM, I used Onyx to repair file permissions, and am out of ideas. Any help would be greatly appreciated.

How incredibly strange. I am having exactly the same problems with my computer. I just started the same behavior today. I have tried using MacJanitor, repaired permissions, verified disk, but it still will not go to sleep properly. S.M.A.R.T status is verified
I have tested my RAM as described above with no problems surfacing. Anyone else have any ideas that we can try. When I get home on Sunday I will try some more intense investigative tools including re-installing OSX 10.5
By the way, I am running 10.5.4 on a 15" 1.5Ghz G4 Powerbook with 1.25GB of RAM and 28.9GB harddrive free.
Another strange thing I have also observed is that it now takes 10 minutes to start up. 5 minutes on the Apple screen with pinwheel, and then 5 minutes with the blue screen before the cursor appears. After that point startup is normal. Also, even though Disk Utility shows 28 GB free on my harddrive when I try to copy something, it says that I do not have enough free space on my harddrive.
Do you suppose this means that my harddrive is on the way out? Is this also the case of the original poster?

MacBook won't "wake" up from sleep, when being folded

When I "fold" computer it goes to sleep. But, when I flip up the screen again, my Mac won't "wake" up from sleep mode anymore.
Do anyone know how to fix this problem?
BR
Christian
I have a MacBook 2.26 GHz Intel Core 2 duo, Snow Leopard 10.6.8.

I've solved my problem.
I have reset my MacBook's PRAM settings.
It's very easy: link: http://support.apple.com/kb/HT1379
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
Hope this helps
Best regards,
Christian

X1C won't wake up from sleep mode using keyboard

Hi...so finally got my X1C today. One thing I am noticing is that the machine won't wake up from sleep mode when I press any key on the keyboard -- it only wake up by pressing the power key. This is a bit unexpected to me. Is it by design, and is there any way to change this?
Thanks for your help.
Solved!
Go to Solution.

Does it awaken from stand-by if you press the Fn key? That's been the ThinkPad standard for as long as I can remember.

M70-160: won't wake up from hibernate or standby - software or hardware?

I just got maaaaaan!!
works fine, but won't wake up from hibernate or standbye !! unless yur gonna wait for awhile!! 15min or something like that!!
After that it will wake and work normally !
I thought it's overheating problem but now just power it on and when the toshiba logo appear if you turn it off, it won't power on again, but after 15min it WILL !!!
so it's not a heating problem !!
It does that even without HD on it !!
at first it was hibernate and standby problem, now it dose the same with shutdown !!
what can I do!!
i just bought it guys !! ASP is to far a way !!
is there anyway i can do to fix it !!
i do fix PCs alot but not notebooks !!

thank you for your help and the fast replay, i really really appreciate it.
I'll explain the problem in details, right after hibernate or standby IF you press power button the led goes blue, fan starts, HD led lights, battery led, power adapter led (if its connected), and cd player make sound as if it looking for a CD, and THEN fan stopped, HD led goes off, no sound of CD, leaves u only with power button led ON, a nice frustrating Blue
after waiting, u eventually gave up, turn it off by along press on power button, and then no matter wut u do, simply won't start only same sounds and leds as mentioned previously, nothing on the screen as if its dead !! no logo no nothing.
give it a time ( about 15min with battery connected, or 5min or less with battery out) Press the power Button, THERE U GO, works perfectly !!
same case with shutdown but not always as hibernate and standby (though once it did wakeup from standby!!), but most of the time after shutdown u have to wait 15min!!
no USB flash memory connected or anything else !
i did install winXP pro SP2 on it and installed the drivers and Microsoft HOT fixes also, but problem remains.
i also did recovery from the recovery CD that comes with it, also no good !!
i noticed that if u disconnected the battery the unit needs shorter time to be able to wake up or boot. about 5 min.
wut kills me is that the unit works perfectly and i like it !!! i only got this issue with it !!
so wut i need to know is this: Is there anyway to make sure weather if its a software problem or a hardware problem?
its not easy to go to the local service cuz its in another city!! i need to try first wutever it takes to fix it on my own!
thank you for your time!

My mac won't wake up from sleep, what can i do

My mac won't wake up from sleep, what can i do

Can you say more about thermal cut-off? My mac has beene having problems waking from sleep and I have noticed that I hear the fan running ever so slightly in the background. When I depress the power button for a second the fan shuts off.
Just open the side an dlook to see which fan it is. The lower fands are easy to see as well as the video card fan.
When you push the power button and that fan goes off is the machine now fully off? No power light? No fans spinning? Now drives spinning?
I don't recall what I did when my machine shut off with the one exhaust fan running. I think the obvious thing I would have tried would have been to push power button for 10 seconds to shut it down fully. That or actually pull the plug.
When this happens the only way to use my Mac is to restart via the power button.
Then I guess that answers the first question. It must have turned off since pushing the power button again was the normal reboot.
I can't find any helpful info on thermal cut-off so I was wondering if you could explain what it is, what causes it, and more importantly what I can do to fix it?
That was my term for it. What else could it be? Without its fan video card would get extremely hot and throw off all that heat. Whats the point of having temperature sensors in so many places other than to use that info to protect the machine against damage due to overheating? So my assumption was card gets hot, sensor (probably the pci slot 1 temperature sensor) senses it, kills the machine. It's also seems logical to me that the circuit(s) handling temperature overloads would want to keep a exhaust fan running to dump the heat out of the machine to further protect any damage from the heat.

It won't wake up from sleep after I open it. If I close it and then open it, it doesn't wake up for at least 5 minutes.

just upgrade my macbook air to yosemite. now when i physically close the computer and open it back up, it won't wake up from sleep mode. I tried pressing the power button, but it wouldnt turn on. Then once it somehow turned on by itself, I tried a PRAM and SMC reset. Then I tried closing and opening the computer again and I still had the same problem. nothing has worked. when i do get the computer on, i randomly goes into sleep mode again. I've check the settings for display and it says after 45 minutes of nothing it will sleep.

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully (some of it is hidden by disclosure triangles) and don't skip any of the steps, including the ones under the heading "Additional troubleshooting." If you don't understand any of the steps, ask for guidance.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
           ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
          Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
           ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.
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, 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 Console in the icon grid.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
Step 5
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

G5 won't wake up from sleep & fans go to high speed ???

G5 won't wake up from sleep & fans will go to high speed within a few minutes of it going to sleep. Whether I put it to sleep or it goes to sleep on it's own per my preferences in energy saver. I have to manually shut it down by holding the power button in. I ran the system hardware dvd and results were good. I have repaired permissions, reset the PRAM.
Any ideas?

"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Won't wake up from sleep mode

I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

Since you have a new machine, I would call Apple immediately and have them deal with the problem.

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