  • Battery life decreased after upgrade to 11.04

    - by bruno077
    After upgrading from Ubuntu 10.10, my battery life has decreased dramatically. There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours. I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet? I have a Core 2 Duo ULV, Thinkpad Edge 13

  • suspend error on 14.04 LTS

    - by user1450663
    I've looked around and seems like various problems around suspend are wide spreaded for 14.04 release, nevertheless I haven't seen exactly my problem reported, nor my laptop model mentioned. So, the problem. When I press sleep button system seems to be going into suspend, i.e. screen goes black, it stops responding on the keyboard and wireless LEDs turn off, however the power LED doesn't go into suspend state and CPU fan also keeps spinning. But unlike the other problem described here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315435 when I close the lid and reopen it - system wakes up and goes back to normal locked screen state, so reboot is not needed. System details: This is a clean freshly installed Ubuntu 14.04, 32bit Laptop Dell D630 kernel 3.13.0-34-generic

  • Limiting what resumes computer from suspend

    - by user1399195
    I'm having a ton of trouble getting Suspend to work with my laptop. I want to start using Ubuntu but this is a pretty important aspect since I take my laptop with me everywhere. Anyways, I wanted to narrow down the possible problem with my laptop. What happens is that when I suspend my computer, within seconds, it just boots back up. I have changed /proc/acpi/wakeup to where everything is disabled but that did nothing. Is there a way where I can disable every feature from waking up the laptop except the power button?

  • Linksys WAP54G v3.1 no access, power and link LED solid

    - by user142113
    I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers

  • Windows XP - Power surge on hub port

    - by Swift-Tuttle
    Since last few weeks I constantly get this error, as status bar balloon: Power Surge on Hub Port - A USB device has exceeded the power limits of its hub port. Due to this now I am unable to access any USB devices properly, they get disconnected intermittently. I did quite a few things to resolve this problem, firstly obviously through the Windows help. I even tried all the things told on the Microsoft website(which essentially says is to check and update the driver) but in vain. One suggestion, I found when I google'd was to disable the USB2 controller through the Device Manager and since at every startup the System configuration comes up complaining that it has been changed etc.(On that same site it is mentioned to ignore this message.) But after everything I still cant solve this problem. Any help is much appreciated. The system is installed with Windows XP service Pack 3 and all the updates till last month. Please let me know if any other hardware info is required. **UPDATE** My laptop is about 5 years old now, its an HP with Celeron 1.4G processor. Windows XP SP3 installed. All latest windows updates installed. 2 USB ports available. BIOS is HP 68DTD ver F.0A Do I need to update my BIOS from somewhere ? or is this a hardware problem altogether?

  • What is wrong with those crontabs?

    - by Guillaume Boudreau
    I want my projectors to Power On before the mall opens, and Power Off when the mall closes. So I created crontab entries (that I placed in /etc/cron.d/mall), but today (Thu Nov 22 18:58:29 EST 2012 is the current date on that server), the power-off.sh script got executed at 17:20 (see syslog excerpt below). Being Thu, Nov. 22, I would have expected the power-off.sh script to be executed at 21:20, per the 4th crontab line below. Why did power-off.sh execute at 17:20? What is wrong with my crontab entries? Content of /etc/cron.d/mall: 40 9 22-30 Nov Mon-Sat myuser /usr/local/projectors/power-on.sh 40 10 22-30 Nov Sun myuser /usr/local/projectors/power-on.sh 20 18 22-30 Nov Mon-Wed myuser /usr/local/projectors/power-off.sh 20 21 22-30 Nov Thu-Fri myuser /usr/local/projectors/power-off.sh 20 17 22-30 Nov Sat-Sun myuser /usr/local/projectors/power-off.sh 40 9 1-22 Dec Mon-Sat myuser /usr/local/projectors/power-on.sh 40 10 1-22 Dec Sun myuser /usr/local/projectors/power-on.sh 20 21 1-22 Dec Mon-Fri myuser /usr/local/projectors/power-off.sh 20 17 1-22 Dec Sat-Sun myuser /usr/local/projectors/power-off.sh syslog excerpt: $ grep power-off.sh /var/log/syslog Nov 22 17:20:01 lanner-ubu-c2d CRON[23007]: (myuser) CMD (/usr/local/projectors/power-off.sh)

  • How to disable Power off/Power on sound on Android phone? [closed]

    - by yvolk
    My Android phone (Android v.2.1) produces loud sound both before Power off and after Power on (boot) is being completed. I don't want to turn the sound off before reboot/powering it off and to turn sound on after reboot every time I'm restarting my phone. I just want to get rid of these sounds forever :-) How can I do this (maybe executing some script, changing some properties... preferably without rooting my phone)? Update: Thank you Christopher Orr! I've also found some information that partially allows to achieve what I'm looking for (on androidforums.com): "if you are going into SettingsSound & displayNotification ringtone that sets your notification tone for app updates, power on (rebooting) etc. If you want to change notification for messages you would have to go into messaging and then hit the menu key for notification option. You can do the same for email accounts as well." So I disabled Power on/off sounds (plus something else... but I didn't notice undesired side effect yet...) with built-in settings.

  • Laptop Charger Not Recognised Properly on Samsung NP900X3F

    - by user193732
    Firstly thanks for your time. Secondly, having an issue with my power charger on my Samsung Series 9 NP900X3F. When I boot into Ubuntu with the charger plugged in it recognises it as charging. When I unplug the charger after this it is still says it is charging. If I suspend in Ubuntu then plug/unplug during this suspended state it recognises it, but not during normal running. If I knew a little more I'm sure I could grab logs and find out what the difference between wake on suspend and normal running is, but alas I need help! I also am having issues with my keyboard backlight via the fn keys, but that I care about far less. Thank you very much. Linux mikey-900X3F 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (I upgraded my kernel version to remove heinous horizontal artefacts I was getting) Happy to list more info about my system, ima bit of a noob. I did try searching however I can't find any questions at all about my system or related models with the same issue.

  • screen does not wake up after suspend/ brightness will not adjust

    - by Nathan
    My computer is one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16834230467 Asus Zenbook UX32A-DB51 Just bought it yesterday. Set to "suspend" when I close the lid, but when I open it up again I just get a black screen. Pressing the power button doesn't work, not does clicking the mouse or any key combination. The same is true if I leave the computer until it suspends. Black screen, no response, have to reboot. I also can't seem to adjust the brightness. I put "brightness up" and "brightness down" function keys in, and when I push them it shows the brightness level as going up and down on the meter, but the screen does not actually become more or less bright. I am totally new to all of this. Please tell me what additional information you need to help me and where I can find it. Thanks! Edit: Tried the following: sudo gedit /etc/default/grub Change the line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="acpi_osi=Linux" sudo update-grub Restart your linux And "acpi_backlight=vendor" both to no avail.

  • Why does 12.04 try but fail to hibernate, even after I enabled hibernation?

    - by Roger Davis
    Regarding the below (-----) info from another post, my system will try (as is said below) to hibernate, but it won't get all the way there. Hard drive activity stops, but it does not shut down. If I turn the power off, then back on, it will start, but I have to "restore previous session" in the browser and other open apps don't restart, with the accompanying hassle. So because it tries, will the suggested fix then cause it to work correctly, or is the literal "try" not really what he means?!? PLEASE NOTE - this is a desktop system, not a laptop. Before enabling hibernation, please try to test whether it works correctly by running pm-hibernate in a terminal. The system will try to hibernate. If you are able to start the system again then you are more or less safe to add an override. To do so, start editing sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla Fill it with this [Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes Save by pressing Ctrl-O and exit nano by pressing Ctrl-X Restart and hibernation is back!

  • What are some potential uses of Asterisk (PBX) for a "power user"

    - by user26453
    So I read a lot of good things about Asterisk. I am not however looking to run a call center or small business setup. I am still interested what potential uses it has for me as a "power user" and what features I could harness for my communication needs. I'll throw out that I currently use other technologies like Google Voice, Skype, and a cellphone of course. So, what potential uses could Asterisk PBX have for a user like me?

  • Xfce power manager warns HAL daemon is not running, no keyboard on startup on Ubuntu

    - by Macha
    I changed my grub boot options to add "vga=0x323" to them to resolve some issues with corrupted display during startup/shutdown on my laptop. The next time I booted the system up, I got a warning over the login screen saying Xfce Power Manager HAL Daemon not running The keyboard and mouse are unresponsive. After a minute or so, they start to work and the system functions as normal. How can I solve this?

  • Is the 4pin atx power plug required?

    - by rockinthesixstring
    I know the answer is probably a resounding YES, but I just wanted to double check. I just purchased a new chassis for my PC and now my 4pin cpu power plug doesn't reach. I'm wondering if the 4 pins are required for operation, or can I get by for the weekend without it until I can go get an extension?

  • What happens in case of utility power failure?

    - by Jake
    (in the office) Today, the UPS battery replace warning light lit up and there was a slight panic as the all the technical people will not be around the next few days. But after thinking a bit further, I realise that in case of power failure, no client computers will be able to turn on in the first place and operations will be disrupted regardless of whether the UPS keeps the server up. This makes me wonder if the UPS is really such a critical component? What do you think?

  • 2 "P4" power connectors *AND* an 8 pin EPS connector -- all necessary?

    - by chris
    I recently bought an Arima SW350 motherboard. It supports 16 ddr simms as well as 2 opteron 2xx CPUs, so I imagine it may have pretty heavy power requirements... It has a 24 pin ATX power connector, 2 4 pin "P4" power connectors, and an 8 pin EPS power connector. My supermicro power supply has a 24 pin ATX connector and the EPS connector, and one P4 connector. Can I safely run this thing with only one P4 connector plugged in? Can I safely get a "hard disk to P4" adapter and use that to power the other P4 connector on the motherboard? Do I just need a new power supply? The board's documentation is pretty thin on the topic.
