T530 wakes up immediately after it entered sleep mode or hibernation mode.

My brand new T530 comes with windows8, but I found a strange thing that it can 't enter sleep mode or hibernation mode, every time it will wake up immediately even I close the lid. The battery will be ran out in several hours.
Anybody has same problem?

Attempt to enter sleep or hibernation, then when it wakes up right after, go to Command Prompt and run "powercfg -lastwake". It'll tell you what woke up the system.

Cannot resume workout after Nano enters sleep mode

If I pause my run for longer than about a minute, my Nano goes to sleep (i.e. the screen goes blank - I believe that this is a regular Nano feature). When I try to resume my workout by pressing play/pause, my workout ends. Has anyone had a similar problem? Is there a way to prevent the nano from going into sleep mode if it is paused for more than a minute or so? Could there be a problem with my chip?
Thanks.

Hi and welcome to the forum!
Go to Device Manager, right-click the wireless network adapter and then select Properties. Now head over to the Power Management tab, uncheck the option that says “Allow the computer to turn off this device to save power”, and click OK. Now go to the Advanced tab and make sure Transmit Power is set to maximum.
Also go into lenovo Power Manager, switch to Advanced mode and make certain that for wireless card Maximum Power is selected for both battery and AC Adapter.
Hope this helps.

Unable to connect to HP Officejet 6600 after printer enters sleep mode

Actiontec MI424WR wireless router
HP Officejet 660
Dell XPS 8300 (Windows 7, Windows Firewall, Microsoft Security Essentials)
IP Address range: 192.168.1.x
Printer is assigned static IP address
The HP Officejet 6600 printer is easy to set up and works great...for about 15 minutes. Then the printer goes to sleep and the wireless connection dies. Repeatedly. I am never able to restore the wireless connection without rebooting the printer, computer AND the router. I've been dealing with this issue off and on since I purchased the printer four months ago.
I can see from forums that I am not the only one with this issue. What I can't see (anywhere) is a solid fix for the issue.
I can tell you:
1. It's NOT the windows firewall. I've tried it with the firewall on and the firewall off.
2. It's NOT the antivirus software. I've tried it with the service running and the service stopped.
3. It doesn't matter whether the IP address is statically assigned or assigned with a DHCP reservation (though you do need to do one or the other)
4. Adding an ARP static entry helped a little bit to get rid of the "Host reports destination unreachable".
5. It doesn't matter whether the Bonjour service is running or not.
6. It doesn't matter whether the printer is configured for wireless direct printing or not.
7. I updated to the most recent firmware for the printer: that didn't help.
8. I'm positive that the printer is connected to the wireless router correctly.
I ran telnet from my pc to the printer (on port 80) and received no response. I can only conclude that somehow, there's a service that's supposed to be running on the printer that has died or that fails to register properly with the router.
Right now, I'm back to a direct connection between the printer and the computer (usb cable). Which means I can only print from the one device.
I have no intention of purchasing another HP product any time soon. I'll be sure to go out of my way to find knock-off cartridges as well.
Ugh.

Just to verify, what is the DHCP range in the router? Starting and ending addresses? What is the printer static IP at?

Computer enters sleep mode shortly after leaving sleep mode. Defect?

I have a problem. It's not a serious problem, but since it seems to be hardware related it might cause problem in the future.
It's pretty simple. Let's say I fold the computer screen down and leave the computer in sleep mode. If I then fold it up again it will automatically enter sleep mode once again 25-30 seconds after waking up. It doesn't matter what I do. I can be completely passive or open any app and move the cursor as much as I like. After roughly 30 seconds the screen turns black and I have to press a key to wake it up.
It never enters sleep mode any other time if I don't choose so, it's always after being in sleep mode already. And it happens 80-90% of the time, but I have not noticed a pattern for when it doesn't.
Naturally my settings are in order. I just updated it today and no difference after one attempt with the new OS version.
Any ideas?

Sleep.
Shutting down a Mac is never required. It is best to let it sleep, unless you are planning to not use it for a period of time considerably longer than a few days.

17 in MacBook Pro needs to be shut off to wake up after put into sleep mode

When I close my 17in Mac book pro it will enter sleep mode but when trying to wake it up I can hear the fans turn on, but the screen will stay black and I have to manually hold the power button and I get an error message when I turn it back on saying that programs didn't close out properly. I recently had to take my computer in to get it repaired and it has been acting this way ever since I got it back. Which was early may.

27Xi stays on displaying "no source signal" after I turn off my PC or PS4, doesn't enter sleep mode.

I started having this issue a few weeks ago. The monitor no longer enters sleep mode for whatever reason after I turn off my devices connected to it (currently my PC via DVI and my PS4 via HDMI), it turns on and displays a box with "no source signal" and never goes to sleep. Before it displayed a box with "monitor going to sleep" for a few seconds and the panel turned off as the montor entered sleep mode. This is extremely annoying. How do I fix it? What's wrong with it? I already tried a factory reset.

Hello, try this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Mac mini keeps entering sleep mode

Hi. I have a Mac mini that has this annoying problem where it keeps
wanting to enter sleep mode. This problem seemed intermittent at first.
What I notice is that my mini would enter sleep mode whenever I try to
encode mp3. This seems reproducible. When it enters sleep mode,
I can wake it up by pressing the power button. However, it goes back
in sleep mode after a couple seconds after it wakes up. The only way
I can get it out of sleep mode is to quit iTunes and eject the audio
CD.
Things I've tried:
Energy Saver settings: Computer sleeps after 3 hours inactivity,
display sleeps after 3 hours inactivity, unchecked "Put hard disk(s)
to sleep when possible". I tried disabling energy save. No luck.
I also tried to uncheck "Allow Nap" box in the Processor settings.
However, it always checks this after a reboot.
If I insert a DVD movie, I can watch it w/o any interruption.
Anyone else seen this problem? Thanks in advance.
Jim

Hi Carl. I was unable to find com.apple.AutoWake.plist in my
system. Deleting com.apple.PowerManagement.plist didn't
help.
I decided to try your open firmware instructions. I like the
boot loader. It reminds me of the Sun's boot monitor.
I did the reset-nvram, set-defaults, reset-all. It didn't
help though.
I don't think it is my power supply, either. The reason why I
don't think this is the problem is I can watch DVD and listen
to audio CD just fine. My sleep problem would only occur
when I try to rip an audio CD. I can assure you that I draw
plenty of power just playing a DVD movie.
My guess is I have a power management configuration
issue or a hardware problem. Since this has a Unix core
underneath, I started poking around in the usual places
for log files. I found the familiar /var/log and stumbled
on system.log. Looking at the file, I found something
that caught my eye.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Doing a 'grep overtemp system.log', I got the following:
Aug 17 01:04:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:56 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:51 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:00 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
If you look at the time stamp, you'll see that each event
is only a few seconds apart. This matches with what
I was seeing. Machine goes to sleep. I press the power
button and it wakes up and goes back to sleep. One
big endless cycle. The only way I managed to get out
of it is to quit iTunes and to eject the CD.
Yes, I did install the Xcode 2 development kit that came
with the Mini MAC OSX setup. I eventually want to write
software for the Mac. So, I most likely installed the
CHUD tools package that you had mentioned.
I think the equivalent command line command for
disabling the nap feature is 'hwprefs -v cpu_nap=false'.
When I do that, I get the overtemp event and my mini
goes to sleep. Zzz.
In any case, my mini seems to be detecting false overtemp
condition. Either I have a bad temp sensor or my power
management overtemp threshold is set way too low. It's
possible encoding audio CDs is enough to heat up the
PPC core, but it happens way too fast. I'm thinking my
temperature sensors are not set correctly. If anyone has
schematics for the mini, it would most likely be a Dallas
temp sensor chip. I'm not ready to open up my mini yet
since it is still under warranty. I'll take it in the Apple
store in Walnut Creek this weekend.
Anyway, thank you guys for all your help. I found my
experience on this forum to be quite pleasant. People
here are very helpful.

Mac Pro unexpectedly enters sleep mode

Ok so I installed Leopard last weekend on my Mac Pro and all initially went well with the install. After installation was done, software update appeared and stated I had approximately 4 downloads to install. So I had done this and prepared to reboot. Before rebooting, a window appeared stating that it needed to update the Boot cache. So I clicked on "OK" and the computer went into its shutdown sequence. When the computer reset, I noticed there was no start up chime and the system just sat there with a black screen. I thought perhaps it was updating the boot cache and it may take a while to finish. So I went afk for about an hour and came back. Still nothing. This is when I knew there was something seriously wrong with my system.
After speaking with Apple support and trying several things to get it to boot, the support rep stated that it will need to go into the shop for repairs. I had taken it to an authorized service center and they diagnosed the problem as a bad logic board. They had replaced this and had ran their diagnostic tools on it to make sure it was running normally. They kept it overnight and ran Apple Service diagnostics in a repeating loop on the system. They had also cold booted the system 30+ times per the work order.
After I brought it home and booted it, everything was seemingly running fine. Then I received a page from work (I'm a support rep) which required me to boot into Windows using Boot Camp to solve a client's problem. After I had done this, I booted Leopard back up and was playing around in it for a few minutes to check out some of the new features. I had then ran World of Warcraft to play a bit and to check out the performance increase in Leopard. After about 5 minutes of playing, my system unexpectedly entered sleep mode. Obviously I was confused so I had brought it out of sleep mode by hitting the enter key. The system came back for about 2 seconds and immediately went back into sleep mode again. This happened about 4 or 5 times before I finally shut the system down.
The first thing I did after reboot is to check the energy saver options. Both hard drive and monitor energy options were set to "Never". I then checked for software updates. There was both an SMC firmware update and a Boot Camp EFI(?) firmware update. I had done the SMC firmware update first and then after successfully updating this, I had done the Boot Camp firmware update. After reboot, the system went into sleep mode on its own approximately 5 minutes after reboot. This time I had made sure NOT to run my game as I had a suspicion that this could be causing the problem. It entered sleep mode anyway unexpectedly. After waking it up again by hitting the enter key, the desktop appeared again for about 2 seconds before going right back into sleep mode. I called the service center again and they said I would have to bring it in for them to look at. Needless to say, I am NOT very pleased.
Has anyone ever heard of anything like this happening with a Mac Pro? I had never had any problems when I was running Tiger with any application, not even my game. The service rep where I took it said it was just bad timing that the logic board went during my OS upgrade and that the two had nothing to do with each other. My brother has a Mac Pro as well and he had upgraded to Leopard. Of course his computer works fine where mine is a sleeping fool. Does anyone have any ideas or theories as to what could be causing this? More importantly, does anyone have any suggestions on how I might be able to fix this on my own? If you could please let me know, I would appreciate it. Thank you in advance for your time.

Wow, who are you dealing with? The first time my logic board was replaced, the techs never bothered with looking at anything else as being the problem. However, when I pointed out the power supply fan problem, they focused on that being the cause of the problem and fixed just that. I was somewhat concerned as I know some of these techs do not look at other parts of the machine as potential problem causers. I was afraid that I would hook up my system only to experience the same problem as before. Luckily, that was not the case.
I am glad that your system appears to have the same problem as mine did. I would suggest that if you take it back to them again for a fan fix to have them run the system for about an hour after replacing it. They should be opening apps, checking the iStat widget, etc to try and make it break. If they can't after an hour or so, I think it should be ok.
This whole ordeal makes me question the quality of parts used by Apple. My brother has an iMac G4 where the hard drive died after 2 months of getting it new. Now this issue with mine and yours with the bad logic board and the power supply fan. Who knows how many other customers report hardware related problems?

Running Windows 7 64 bit Professional
Problem: Within days of building computer in January the computer started to automatically reboot seconds after shutdown or entering sleep mode.
Attempted Fixes:
-Total re-install of Windows + BIOS
-Updated BIOS via LiveUpdate
-Rolled back to initial BIOS that came with MB
-Changed between registry option of "PowerdownAfterShutdown" between "0" and "1"
-Disabled Wake-Up Events in BIOS
-Changed to OS controlled Wake-Up events
-Changed "Restore after AC Power Loss" to off in BIOS
-Ordered a new PSU, replaced PSU
Regardless the fix, if I try to shutdown - the computer reboots within a few seconds. If I try to put it in sleep mode, it boots right back up. The only way to get the computer to shut off is by manually turning off the PSU.
I've seen that there have been frequent power-cycle issues with this particular motherboard in comments on newegg.com, just wondering if this issue has been encountered and if there is a fix available?

Quote from: Bernhard on 17-February-12, 00:10:35
Is this with no case wire connections to any of the headers? i.e. if you start it by shorting the on/off pin headers with a screwdriver tip.
Yeah, as shown here.
http://www.computer-how-to-guide.com/motherboard-troubleshooting/motherboard-post-test-how-to/
Shorted on with flathead, boots up fine. After flipping off the PSU to turn it off and then flipping the PSU back on, the dang thing waits a few seconds and boots right back up. No short required. At this point I think a ghost might be living in my computer.

All-in-one 6830 printer Does not enter sleep mode when connected to a phone line

HP staff help. HP all-in-one printer 6830 does not enter sleep mode when conntected to a phone line via 1-Line jack. The Firmware is PNP1CN1521AR. On August 1, 2015, I purchased an HP all-in-one 6830 printer and upgraded to firmware PNP1CN1521AR.When a phone line is connected to 1-Line jack of 6830, the printer will no longer enter sleep mode and the display remains on indefinitly.Removing the phone connection either from the wall outlet or from the printer causes the sleep mode to work correctly again where the control panel display turns off after 5 minutes (or optionally after 10 or 15 minutes).This problem was previously reported by a user and has not been resolved, see:http://h30434.www3.hp.com/t5/Other-Printing-Questions/Sleep-mode-of-Officejet-Pro-6830/td-p/4772182 The user did not receive a resolution to this problem according to the thread.
There seems to be a 6830 printer firmware or hardware problem causing this. HP should be able to confirm this problem on 6830 easily.
Please advise ASAP.
Thanks

It's a regular analog phone line. I've tested it with other phone lines. No difference. I have another all-in-one printer which works fine (goes to sleep mode) when plugged into the same phone line.
The 6830 works ok in other aspects. The only problem is the sleep mode. Any 6830 with the firmware I mentioned should replicate the same result, regardless of anything else. The previous firmware to PNP1CN1521AR also created this problem according to the original report of this problem by another user.
I'm sure there's a bug in the firmware. A subroutine in the firmware monitoring the incoming fax ringing, mistakenly, sees the voltage across the phone jack pins as an event and wakes up the printer instantly even though there's no ringing. As the previous user also suspected, there seems to be an error in the phone line voltage threshold used by the firmware. The present firmware always sees a ringing at the phone line which causes it to never stay in sleep mode.

Windows 10 - won't enter sleep mode

So I updated to windows 10 roughly a week ago. I have had sleep issues from day one with it not being able to wake up if it didn't enter sleep mode properly. I ended up just remembering to hit the power button or shut the lid and that was enough to put it into sleep mode and was able to wake it after opening. I saw another user said to update the Bios driver... that was working til a windows update. Two/Three days ago windows had an automatic update and that seemed to cause the problem again. But now I cannot get it into sleep mode at all even with the power button, closing the lid and even going to start and hitting sleep. it turns off the screen and the power light continues to just be on without blinking and the fan keeps running. This computer is only 6 months ago and I am getting frusterated. I will probably go back to 8.1 as having to hard power down the computer can't be good for it everytime I walk away and forget to completely power it down. Does anyone have another solution I can try before I jump ship?

I have installed all updates from Windows Update and all drivers from Toshiba US website. I can't find the Service Station for Windows 10 from Toshiba website. I only found the one for Windows 8.

MacBook starts and instantly enters sleep mode

In the past few days I've been experiencing a reoccurring problem with my macbook pro. I press the power button, hear the startup of the drive, and then sometimes the display will turn on for a second(mostly stays off), and then enters sleep mode instantly. I can not get on my macbook unless I turn it on and let it sit for 15-20 minutes, then MAYBE the display will activate. Please help.

Do you hear a chime at startup? How do you know it is entering sleep mode and not turning off? Does the cursor move on the screen? Here is something from another user's experience:
I had the same issue with my 2008 iMac and Apple support walked me through the fix yesterday...
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.

IMac beeps once before entering sleep mode

My iMac 24 inch has started to beep once before entereing sleep mode. The LED thinks blinks whilst it is asleep, which I assume is normal. Is this indicative of a hardware fault? I understand that a single beep on startup indicates a ram problem.

If you listen carefully, you may find this beep is
coming from the hard drive, not the speakers (plug
headphones in and find out if it still makes the
beep).
Some hard drives make this beep if they have a
re-positioned write, which is a non-fatal error. You
can usually reformat to re-allocate the block and
stop the error, or you can live with it.//
Hi
Yes you're correct, it doesn't come from speakers. It not makes the same faint beep (rather like a heart monitor blip) when closing down and always after the screen has gone blank. I have noticed that if you put a CD-ROM in the DVD drive and its still spinning when you put it into sleep mode you don't get the sound.

Network issues after returning from sleep mode

I'm noticing this issue on T440, Twists, T420s, whether it's Windows 8, Windows 8.1 or Windows 7. Sometime around the end of last year and the beginning of this year, my users suddenly started reporting problems with the machines after returning from sleep mode. The network adapter (whether plugged in or using wifi), would show limited connectivity and would not connect to the internet until the machine is rebooted.
I've tried updating drivers, using system restores, disabling the network adapters from shutting down to conserve power, OS network diagnosis & network adapter resets, none of which has worked. Hibernation is disabled on all machines.
The only fix I have is to reinstall the OS over the top of the system and reinstall all updates. Looking for help with this issue.
Thanks!
Solved!
