• Why does my laptop resume immediately after suspend?

  - by Igor Zinov'yev

  I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er Pavilion laptop (Intel Core 2 Duo). Here are the relevant log sections: kern.log: Jun 1 10:42:21 igor-laptop kernel: [ 2225.131171] PM: Syncing filesystems ... done.

  Here is an extract of results.log: MTRR validation. Test 1 of 3: Validate the kernel MTRR IOMEM setup. FAILED [MEDIUM] MTRRIncorrectAttr: Test 1, Memory range 0xc0000000 to 0xdfffffff (PCI Bus 0000:00) has incorrect attribute Write-Combining. FAILED [MEDIUM] MTRRIncorrectAttr: Test 1, Memory range 0xfee01000 to 0xffffffff (PCI Bus 0000:00) has incorrect attribute Write-Protect. ==================================================================================================== Test 1 of 1: Kernel log error check. Kernel message: [ 0.208079] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored ADVICE: This is not exactly a failure mode but a warning from the kernel. The _OSI() method has implemented a match to the 'Linux' query in the DSDT and this is redundant because the ACPI driver matches onto the Windows _OSI strings by default. FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3.512783] ACPI Error : Method parse/execution failed [\_SB_.PCI0.GFX0._DOD] (Node f7425858), AE_AML_PACKAGE_LIMIT (20110623/psparse-536) ADVICE: This is a bug picked up by the kernel, but as yet, the firmware test suite has no diagnostic advice for this particular problem. Found 1 unique errors in kernel log. ==================================================================================================== Check if system is using latest microcode. ---------------------------------------------------------------------------------------------------- Cannot read microcode file /usr/share/misc/intel-microcode.dat. Aborted test, initialisation failed. ==================================================================================================== MSR register tests. FAILED [MEDIUM] MSRCPUsInconsistent: Test 1, MSR SYSENTER_ESP (0x175) has 1 inconsistent values across 2 CPUs for (shift: 0 mask: 0xffffffffffffffff). MSR CPU 0 -> 0xf7bb9c40 vs CPU 1 -> 0xf7bc7c40 FAILED [MEDIUM] MSRCPUsInconsistent: Test 1, MSR MISC_ENABLE (0x1a0) has 1 inconsistent values across 2 CPUs for (shift: 0 mask: 0x400c51889). MSR CPU 0 -> 0x850088 vs CPU 1 -> 0x850089 ==================================================================================================== Checks firmware has set PCI Express MaxReadReq to a higher value on non-motherboard devices. ---------------------------------------------------------------------------------------------------- Test 1 of 1: Check firmware settings MaxReadReq for PCI Express devices. MaxReadReq for pci://00:00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) is low (128) [Audio device]. MaxReadReq for pci://00:02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection is low (128) [Network controller]. FAILED [LOW] LowMaxReadReq: Test 1, 2 devices have low MaxReadReq settings. Firmware may have configured these too low. ADVICE: The MaxReadRequest size is set too low and will affect performance. It will provide excellent bus sharing at the cost of bus data transfer rates. Although not a critical issue, it may be worth considering setting the MaxReadRequest size to 256 or 512 to increase throughput on the PCI Express bus. Some drivers (for example the Brocade Fibre Channel driver) allow one to override the firmware settings. Where possible, this BIOS configuration setting is worth increasing it a little more for better performance at a small reduction of bus sharing. ==================================================================================================== PCIe ASPM check. ---------------------------------------------------------------------------------------------------- Test 1 of 2: PCIe ASPM ACPI test. PCIE ASPM is not controlled by Linux kernel. ADVICE: BIOS reports that Linux kernel should not modify ASPM settings that BIOS configured. It can be intentional because hardware vendors identified some capability bugs between the motherboard and the add-on cards. Test 2 of 2: PCIe ASPM registers test. WARNING: Test 2, RP 00h:1Ch.01h L0s not enabled. WARNING: Test 2, RP 00h:1Ch.01h L1 not enabled. WARNING: Test 2, Device 02h:00h.00h L0s not enabled.

• How To Prevent Your Computer From Waking Up Accidentally

  - by Chris Hoffman

  If you find your Windows computer waking from sleep for no apparent reason, your computer is either being woken up by a hardware device – such as your mouse — or scheduled task set to wake your computer. In some cases, the cause may not be obvious. For example, if your laptop occasionally wakes up for no apparent reason, it’s possible that the floor is shaking a bit, causing the mouse to vibrate slightly and wake the computer. Java is Insecure and Awful, It’s Time to Disable It, and Here’s How What Are the Windows A: and B: Drives Used For? HTG Explains: What is DNS?

• Sleepyti.me Calculates an Ideal Bedtime Based On Your Morning Schedule

  - by Jason Fitzpatrick

  Sleepyti.me is a web-based sleep calculator that uses average sleep cycle lengths to calculate what time you should go to bed in order to rise at a predetermined well rested and alert. Plug in the time you need to wake up and hit Calculator. Sleepyti.me charts out the 90 minute sleep cycles that will occur over your sleep period and, working backwards, suggests time you should fall asleep in order to wake up in between those cycles in order to increase alertness and have an easier time peeling yourself out of bed. For example, let’s say you need to get up at 7:00 AM. It will suggest you fall asleep at 10:00 PM/11:30 PM/1:00 AM/2:30 AM in order to align your sleep cycles with your proposed rising time.

• Windows Not Sleeping All Night

• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• Can I make my PC backup and then sleep on demand with WHS?

  - by Simon

  I really hate the way that WHS backs up at a particular time in the morning. First of all I don't EVER want my computer turning on when I am not there. EVER. I have a Core-i7 laptop which literally could burn the house down quite easily if it were to turn on in a bag. I also don't ever want my PC to sleep unless I tell it to. I don't have hibernation or sleep enabled and this is the only way that WHS will sleep after a backup is complete. I know that Windows 7 has the ability to disable waking up when on battery power but it doesn't seem to work on my laptop. These are the possibilities (with wake timers left as default): 'Wake this computer for backup' ON - it turns on in my bag if i forget to turn it off - and stays on when the backup is complete. 'Wake this computer for backup' OFF - it backs up in the morning, but I need to leave the machine on all night. I say 'Backup Now' and then it backs up immediately. I can turn it off when its done if I'm still awake, but then that backup appears as 'locked' in the console and not 'automatically managed'. What I'd really like to do is : Click 'Backup and Sleep' and then go to bed. It will backup immediately and then sleep the PC. This backup must be 'automatically managed' and not appear as a 'locked backup' in my console Show me a confirmation that everything was backed up successfully (or not) when I turn it on. Is there any way to achieve this?

• Can I use a Windows Server 2003 Domain Controller but my home router for DNS?

  - by NetworkingWannabie

  Hi All Probably easiest to start with a description of my current setup, which works (oh, and this is a home setup not an office or anything): I have an ADSL modem with a static IP address (192.168.128.1), and its DHCP capability is disabled. I have a permanently powered up Windows Server 2003 machine with a fixed IP (192.168.128.2) which provides my domain controller, dhcp, and dns. The default gateway for everything is my ADSL modem everything is setup to use the WS2003 machine as the primary DNS with the ADSL modem as Secondary DNS just in case the server goes down (everything includes the server itself). Lastly, just in case it's relevant, I have my DHCP leases set to infinite (or whatever the right term is). Everything is pretty hunky dory. Except, that is, for the fact that my server is ALWAYS on, and it isn't always used, so I'm burning juice that I don't need to - my server burns around 120W which isn't immense but isn't irrelevant either, so I'd like to put it into a stand-by state when it isn't being used (the more standby the better) and then get the clients to wake it up. Am I correct in assuming that this won't work at the moment - A given client would need an IP address to wake the machine up, and it needs to machine to be awake to get an IP - catch 22? Assuming I'm correct, can I move to using my router (which is always on) for DHCP? What impact will this have on DC and DNS? Alternatively, does anyone have a better way for me to achieve this? Can I get the server to wake up when it sees clients look for a DHCP server, etc? Wow, that came out longer than expected! Thanks for your help.

• turning off sleep mode on kindle?

  I'm just getting into kindle development, and I want to know if it is possible to turn off kindle's sleep mode? Or is there a way to wake it up (or a way to program it to wake up) by pushing the buttons on the front, rather than using the power button? Not looking for anything to in-depth here, just point me in the right direction or let me know if it is possible.

• Simple continuously running XMPP client in python

  - by tom

  I'm using python-xmpp to send jabber messages. Everything works fine except that every time I want to send messages (every 15 minutes) I need to reconnect to the jabber server, and in the meantime the sending client is offline and cannot receive messages. So I want to write a really simple, indefinitely running xmpp client, that is online the whole time and can send (and receive) messages when required. My trivial (non-working) approach: import time import xmpp class Jabber(object): def __init__(self): server = 'example.com' username = 'bot' passwd = 'password' self.client = xmpp.Client(server) self.client.connect(server=(server, 5222)) self.client.auth(username, passwd, 'bot') self.client.sendInitPresence() self.sleep() def sleep(self): self.awake = False delay = 1 while not self.awake: time.sleep(delay) def wake(self): self.awake = True def auth(self, jid): self.client.getRoster().Authorize(jid) self.sleep() def send(self, jid, msg): message = xmpp.Message(jid, msg) message.setAttr('type', 'chat') self.client.send(message) self.sleep() if __name__ == '__main__': j = Jabber() time.sleep(3) j.wake() j.send('[email protected]', 'hello world') time.sleep(30) The problem here seems to be that I cannot wake it up. My best guess is that I need some kind of concurrency. Is that true, and if so how would I best go about that? EDIT: After looking into all the options concerning concurrency, I decided to go with twisted and wokkel. If I could, I would delete this post.

• Android - Turn off display without triggering sleep/lock screen - Turn on with Touchscreen

  - by NebulaSleuth

  I have been trying to find a way to turn off the display, and wake up from the user touching the touch screen. The device is in an embedded environment where the device is a tablet and the user does not have access to anything except the touch screen (no buttons at all). It is connected to power so the battery won't be a problem, but when I detect no activity I want to turn off the screen so it isn't staring them in the face all day and doesn't reduce the life the LCD backlight. I maintain a wakelock permanently and decide when to sleep myself. The problem is that when I turn off the screen using : WindowManager.LayoutParams params = getWindow().getAttributes(); params.screenBrightness = 0; getWindow().setAttributes(params); The activity gets paused and stopped. And the unit does not respond to a touch to wake it up. You need to press the power button. At that point the "slide to unlock" shows up. I want to turn off the display, and then stay running so I can detect a touch screen event and turn the display back on. I also tried turning the display to a brightness of 0.1, which works on some devices, but the device I need it to work on, only "dims" the display. I also tried this: // First Remove my FULL wakelock //then aquire a partial wake lock (which should turn off the display) PowerManager.WakeLock wl = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Your Tag"); wl.acquire(); however this method does not turn off the display.

• Windows 7 power management in Boot Camp mode

  - by qntmfred

  I have a Macbook Pro with Windows 7 installed in Boot Camp. I have serious problems with the power management and not sure why. I have the default Balanced power plan selected. Many times when I close the laptop and leave it for more than just a few minutes, when I open it back up, it does not awake immediately. I end up having to press the power button to get it to wake up. Sometimes this causes it to wake up in Windows mode, sometimes it reboots completely, sometimes the battery has been drained and Windows has to restart. Is this a common problem? Can I fix it?

• OpenVPN, Great on Windows, VERY slow on Mac...

  - by Phsion

  Hello, I'm not really an IT Pro, but this seemed like the best place to ask this question... I have setup VPN networks in the past, for fun, and everything was great, but now I've set one up for my boss, and while my computers all work great, his Mac machines are almost too slow to work with. Its pretty much vanilla configs all around, anyone have any ideas? Its a TUN routing setup over UDP. Back Story: My boss travels a lot, and wants to be able to access all his files from the road, and is also pretty paranoid about security (even though knows almost nothing about computers). SO i figured a VPN would be the answer. I went with OpenVPN, but there are some other issues. The only ISP we can get in our area besides Dial-UP is a crappy Satellite provider, that doesn't offer public IPs unless your willing to pay, so while the computers and VPN setup are pretty vanilla, the routing and structure is strange to get around this limitation. Specs: Its OpenVPN2, and there are six machines using it (only three actually use it, the rest are my test machines), one Windows 7 laptop, two XP Desktops, one OS X 10.5 Desktop, one 10.6 Desktop, and one 10.6 Laptop. One XP Desktop sits at my house and acts as the server (6Mbs/2Mbs FIOS connection). One XP desktop sits at the office and hosts a webpage that will wake up the Main Mac Desktop from sleep, and also ping all the machines on the VPN and show their status. The main office mac (10.6) stays in sleep mode until it gets the Wake-On-Lan packet from the Office XP, and then it auto connects to the VPN and opens itself up. The reason for all this is the Satellite private IP crap means i cant directly access the office machines outside of the LAN, so everyone connects to my house first, then they talk to each other from there. The Wake On Lan weirdness is because my boss doesn't want to leave the main Mac on all the time, and making a quick and dirty webpage was the easiest way to send a Magic Packet from inside the LAN without confusing my boss. The VPN uses Client Config files to make static IPs for the client. The only thing i found in google was some changes to the VPN MTU settings (down to 1400) but no real help. Oh, and i forgot...all the windows machines just have OpenVPN start as a service. The Mac laptop uses tunnelblick (an OpenVPN GUI) and the Mac Desktops use OpenVPN in normal command line mode.

• How do I make changes to /proc/acpi/wakeup permanent?

  - by Jolan

  I had a problem with my Ubuntu 12.04 waking up immediately after going into suspend. I solved the problem by changing the settings in /proc/acpi/wakeup, as suggested in this question: How do I prevent immediate wake up from suspend?. After changing the settings, the system goes flawlessly into suspend and stays suspended, but after I wake it back up, the settings in /proc/acpi/wakeup are different from what I set them to. Before going to suspend: cat /proc/acpi/wakeup Device S-state Status Sysfs node SMB0 S4 *disabled pci:0000:00:03.2 PBB0 S4 *disabled pci:0000:00:09.0 HDAC S4 *disabled pci:0000:00:08.0 XVR0 S4 *disabled pci:0000:00:0c.0 XVR1 S4 *disabled P0P5 S4 *disabled P0P6 S4 *disabled pci:0000:00:15.0 GLAN S4 *enabled pci:0000:03:00.0 P0P7 S4 *disabled pci:0000:00:16.0 P0P8 S4 *disabled P0P9 S4 *disabled USB0 S3 *disabled pci:0000:00:04.0 USB2 S3 *disabled pci:0000:00:04.1 US15 S3 *disabled pci:0000:00:06.0 US12 S3 *disabled pci:0000:00:06.1 PWRB S4 *enabled SLPB S4 *enabled I tell the system to suspend, and it works as it should. But later after waking it up, the settings are changed to either: USB0 S3 *disabled pci:0000:00:04.0 USB2 S3 *enabled pci:0000:00:04.1 US15 S3 *disabled pci:0000:00:06.0 US12 S3 *enabled pci:0000:00:06.1 or USB0 S3 *enabled pci:0000:00:04.0 USB2 S3 *enabled pci:0000:00:04.1 US15 S3 *enabled pci:0000:00:06.0 US12 S3 *enabled pci:0000:00:06.1 Any ideas? Thank you for your response. Unfortunately it did not solve my problem. all of /sys/bus/usb/devices/usb1/power/wakeup /sys/bus/usb/devices/usb2/power/wakeup /sys/bus/usb/devices/usb3/power/wakeup /sys/bus/usb/devices/usb4/power/wakeup as well as /sys/bus/usb/devices/3-1/power/wakeup are set to disabled, and the notebook still wakes up by itself right after going to sleep. The only thing it seems to react to are the settings in /proc/acpi/wakeup, which keep changing (resetting) every time i power off/restart my notebook.

• Update to 13.10: blank screen and repeated suspend on resume from suspend

  - by user208026

  On my Asus x201e, after updating from 13.04 to 13.10, intermittently when awaking from suspend, my screen will blink to a black screen a few times, offers a lock screen, and then go back to suspend unexpectedly (during this it is possible to quickly login to the desktop before the system suspends again). This will repeat each time I subsequently awake it from suspend. Only a restart will escape the suspend loop. The problem only occurs when suspending by closing lid, not by manual (pm-suspend) or menu suspend. Opening the lid after a manual or menu-initiated suspend works as expected. When an external monitor is attached, the black screen and second lock screen still appear twice upon wake, but the system does not fall back into suspend (though networking is disabled and needs to be restarted). This issue arose in tandem with the already raised issue regarding networking not restarting on wake from suspend, though appears to be distinct from that issue and persists after a fix is applied for the networking issue. This issue only occurs on waking from suspend, never upon booting. And only on the second suspend cycle after reboot. This question duplicates the second, unanswered question included in this closed question and seems to correspond with this reported bug. Any ideas for a workaround?

• My EEEPc 900HA won't turn on/boot. Can it be fixed or does it need to be sent in?

  - by th3dude19

  My EEEPc 900HA stopped booting up out of nowhere. It went to sleep and when I went to wake it up, it wouldn't wake up. I powered down and went to power back up, but no go. The power light comes on solid and the battery/corded power light blinks consistently. There is no HDD activity or light activity. No BIOS. Just the lights described. I've troubleshooted the RAM, HDD, and internal power connections and everything checked out both on battery power and corded power. I've also reset the CMOS to no avail. What else can I do?

• Keyboard freezes / stuck if a key pressed repeatedly

  - by Aziz Rahmad

  I use Acer 4530. This problem has happened long since Ubuntu 10.10 and now that I use 11.04 dual booted with Linux Mint 10. Everytime I press one key repeatedly, like when I read a long article in a website/ebook or when I play games which required me to press arrow keys repeatedly, it would randomly freeze. That is, whatever I press on keyboard has no effect, and that also happens with touchpad. However, the USB mouse works just fine. I later found out that it's not actually freeze but more like it's like the key stuck. For example when I play tetris which I usually press w (down) button repeatedly, after some times it would freeze. And if I put the cursor in, say, browser's address bar, it would type "wwww....." infinitely. The only way I could fix it is by suspend the laptop, either by using mouse or by closing the lid. And instead of suspended, in that case the laptop would automatically wake up and everything will be fine. (Usually my laptop would wake up after suspended by pressing any key) It has happened since the first time I use Ubuntu, 10.10, and it also happens in Linux Mint 10, and until now in Ubuntu 11.04. It never happened when I use Windows, though. Anyone has ever encounter similar problem? Anyone know how to fix it permanently?

• Disable MOUSE wakeup when doing suspend on UBUNTU

  When I do SUSPEND on ubuntu, in order to wake up, i can just move the mouse and the computer will wake up. But, I dont want that the computer is waked up when I move my mouse. How can I do that?

• Sound stopped working

  - by Brian West

  I ran through the troubleshooting at https://help.ubuntu.com/community/SoundTroubleshooting It did not play the test sound, and it also does not play sounds during speaker-test. It does play sounds when I adjust my volume on my computer (using pommed). It worked just the other day, but this is the first time I've tested it since last night, when I put it to pm-suspend-hybrid and it half-woke up (the backlight came on, but it didn't fully wake up), then went back, then half-woke again, but was frozen like that. I had to do a manual reboot of the machine when that happened. Now my sound doesn't work, except for adjusting the volume (where the little "beep" sound plays). During the troubleshooting, it recognized my sound card, the sound modules, and the sound card's installation. I've tried removing ~/.pulse, but to no avail. Also, if it's any help, pulseaudio is running, but pulseaudio --check returns nothing, which the manpage suggests indicates an error. Edit: I should probably clarify that the wake up from the suspend-hybrid was not provoked in any way. I was laying in bed when I noticed my room was brighter suddenly, so I got up to check on it.

• Why does waking a PC up with a timer act differently than with the power button?

  - by Dan Rasmussen

  I have a Windows 7 machine set up as a server. It has no monitor and is only accessed through remote desktop. I set up two scheduled tasks, one to put the computer to sleep at night and another to wake it up in the morning. When it's woken up from sleep via a timer, it stays awake for only a couple minutes before going back to sleep. When woken up by pushing the power button, however, it stays awake all the way until the sleep timer. Why does my PC behave differently in these two scenarios? I have set the PC not to prompt for a user's password on wake, since I worried that the login screen might follow different power rules. I tried SmartPower Configuration but had the same problems. I can provide more details if questions are asked in the comments, but I'm not sure what's relevant.
