• Is there analog of aticonfig --set-powerstate for open source radeon driver?

  - by vava

  I'm running Ubuntu 9.04 on relatively old laptop with ATI Mobility x600 inside. On the last version of Ubuntu, when I was able to run proprietary fglrx driver, I was able to slow down graphic card by aticonfig --set-powerstate 1 and save some battery charge. Now I forced to run open source driver as ATI decided to drop support for old cards. But I can't find a way to control power states now except relying on DynamicClocks option in xorg.conf. But I really know better when and what powerstate I want, so is there a tool that let me change power state manually or at least let me somehow change the behavior of automatic power state selection?

• Effects of enabling DVFS in a CPU

  - by Nrew

  I came up with this energy regulating software called Granola while reading at Ghacks.net I downloaded and installed the software but you need to enable the DVFS function in the CPU. I booted up and tried to enable DVFS in the CPU Configuration in my Asus motherboard(Desktop). But in the description it said that enabling the feature might raise some compatibility issues with the power supply. And I'm afraid that I might ruin the CPU if I do this. Any suggestions, any one here who has tried this before? I don't know who the manufacturer of my power supply is. Would you recommend some software that can determine every possible info about the power supply.

• Linksys WRT54GS V6 Router Blinking Power Light

  - by Frank

  I have a Linksys WRT54GS V6 Router in my possession got it at my local goodwill for 5$. Upon start up the Power LED starts flashing like crazy and at the same time the Ethernet ports all light up once then turn off (DMZ and WLAN never turn on). I can ping the router only by setting a static IP on my Pc. I can also successfully push a file (official Linksys OS and DD-wrt) into it via TFTP but this currently does nothing (no 192.1681.1 Access). Any ideas as to what may be wrong? I think its pretty obvious that it's bricked but.. I keep hearing a whole lot of "if it pings it's fixable" on the internet.

• Is the 4pin atx power plug required [closed]

  - 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? EDIT: Looks like it is mandatory with my Mobo. I tried to post without it and i just got a blank screen. Looks like I'm getting a new adapter asap.

• Windows 7 Wakeup from Sleep then Shutdown

  - by Kevin Hua

  Is this caused by low battery? I have an Asus UX31A, and I left it unattended. As usual, in 5 minutes, it went to sleep mode with the lid still open. I came back a couple hours later, and I noticed the laptop was off. I was still able to turn it on by manually pressing the power button (battery was at 2% though), but I don't understand why it shut off. If it was in sleep mode and the battery was near depletion, then wouldn't that result in a "Windows has recovered from an unexpected shutdown" upon boot? Does Windows have a mechanism to wake from sleep from a super critical battery level to shut down all programs and power down the system completely? I noticed that upon booting, firefox didn't give a fit about improper shutdown. Here are my power settings btw, powercfg -h off has been ran, so hibernation is off. And here is the event log: http://www.mediafire.com/download.php?lbfhl21g0nj2adi

• Can you plug-in the battery while laptop is on AC only?

  - by Ivan Petrushev

  Hello, I'm using my laptop at home with battery removed and only connected to the AC power. However I'm lacking the mobility as my power cord is kinda short. Is it safe from electrical point of view to plug in the battery while the laptop is connected to AC and disconnect the AC power afterwards? What about the opposite side of the question - is it safe (or what the damage could be) if you work on battery, plug in the AC and unplug the battery? If there are differents for different models of laptops, I'm asking about IBM Lenovo T60. Is there such thing as a 'hot-plug battery'?

• Is my Power Supply Unit fried?

  - by Rob

  So my laptop just started smoking where I plug my charger in. I run a netbook, the Acer Aspire One. My charger won't charge it, because when I plug my charger into the netbook, the charging light that indicates the netbook is receiving power turns off. Is there anything I can do to troubleshoot where the problem is and what should I do now? Is just my charger fried and should I replace it. Or could there also be a problem with my netbook and do I need to look for other problems?

• How to use MacBook Pro with external monitor / keyboard / mouse while running on battery only?

  - by Another Registered User

  I'm using my MacBook Pro like a desktop sometimes. But for some reason, when I unplug the Power Supply, it is impossible. The MacBook Pro immediately shuts off. When I turn it on by hitting any key on the external keyboard, it wakes up for about 10 seconds but then goes to sleep again. Sometimes I want to use my MacBook Pro without the Power plugged in to it, just to use the Battery a little bit. And also sometimes when someone else needs my Power Supply. I couldn't find an option in the system preferences. Is there an trick how to get that work?

• Separate brightness/power-saving settings for multiple monitors

  - by MariusMatutiae

  At home, I connect my laptop to an external monitor. Under Linux X server, it works perfectly. Occasionally I watch a movie on the external monitor. When I do, I would like to fold the laptop shut, and just relax. This however triggers my settings for dimming the screen after 10 minutes of inactivity, which in turn extends to the external monitor. I know I could solve the problem by setting dimming to "Never", but this is a waste, causes the laptop to overheat, and is bad for the normal laptop use. How can I set the power saving/brightness specs for the external monitor, independently of the onboard one? I run Debian or Arch, under KDE.

• monitor power and lock screen (Ubuntu Lucid)

  - by xsznix

  Hi, I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself). Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)? Thanks.

• Run Photoshop on VM (virtual machine) to increase calculation power, without violating the licence agreement (EULA)

  - by mecplusultra

  A question concerning the possibility to run Photoshop as VM without violating the licence agreement (EULA) : My Adobe Photoshop is bloody slow, nd sometimes I need to launch thousands of image calculations that have to use hundreds of PSD templates. I want to increase my Photoshop calculation power by creating non-persistent virtual machines on my hosted server. Each VMm would only alive for a few seconds, just enough time to deliver the calculated file. Is this a violation of the EULA? I must clarify that I'm the only one to access my non persistent VMs.

• Microsoft mouse screws up my power settings

  - by Patriot

  Running a new computer with Windows 7 and 64-bit OS. Had a wireless Logitech mouse that worked perfectly with this set up. The mouse was old, and the buttons were sticking and causing double clicks, so I bought a new Microsoft Mobile Wireless 3000 mouse to replace it. The new mouse works perfectly, but now my screen saver is disabled and my computer won't go into sleep mode after 15 minutes as per my power setting. If I hook the Logitech mouse back up, screen saver works fine and computer goes to sleep as it should. Am I missing something, or is Microsoft's mouse just junk. Got no software with the new mouse, so no drivers seem available.

• Schedule power-on with ASUS P8H77-I?

  - by user826955

  Is it possible to have my box with an ASUS P8H77-I to automatically power on each sunday at 0:00 (for backup tasks)? I could not find such an option in the BIOS (or rather EFI). [edit] nevermind, I found it. Its called "RTC alarm date" or sth like this. Still I wonder if there was a possibility to wake the machine like every week on sunday? As it seems, I can only set either everyday, or a single day in the month. I would like to do weekly backups, but this would only allow me to do monthly backups.

• LVM incorrectly reported missing after power failure

  - by mensi

  We have had a major power failure in the data-center. We are using a set of servers for our storage needs. The main server has several pairs of disks mirrored with mdadm. The resulting /dev/mdX are LVM physical volumes and belong to a big volume-group with all our data. After the powerloss, we had the problem that one of the mdadm devices was not auto-detected due to a missing entry in mdadm.conf. As a consequence, the volumegroup had inactive logical volumes due to the missing PV. We were able to fix the mdadm config and reboot. pvscan shows all expected PVs but one LV still does not come up. vgdisplay shows: [...] Cur PV: 3 Act PV: 2 [...] Neither vgscan nor pvscan show any missing devices. What went wrong? How can we force LVM to activate all PVs?

• Objective-measures of the power of programming languages

  - by Casebash

  Are there any objective measures for measuring the power of programming languages? Turing-completeness is one, but it is not particularly discriminating. I also remember there being a few others measures of power which are more limited versions (like finite-state-autonoma), but is there any objective measure that is more powerful?

• Power error handling inside of sql function

  - by user172062

  I have a power function call inside of a sql function. What is the correct way to handle overflow and underflow conditions since I cannot use a Try Catch inside of a function. I am also trying to avoid modifying the ARITHABORT, ANSI_WARNINGS, and ARITHIGNORE settings in the calling code. GO CREATE FUNCTION TestPow() RETURNS DECIMAL(30, 14) AS BEGIN DECLARE @result FLOAT SET @result = POWER(10.0, 300) RETURN @result END GO SELECT dbo.TestPow()

• Printing to Power point

  - by Manoj

  Hi, Similar to a print to pdf option, where we can choose PDF to be the output format when printing something, I am searching for something which can print to a power point file from a file. Is there any such plugin or tool? Also link to a relilable print to pdf tool would be helpful. This essentially would eliminate the export to power point option that the users are asking for. Thanks...

• Design question: Should the client both create the session and the socket?

  - by the_drow

  I have three classes: Client Session Socket Both Session & Socket depeand on the Client to create both objects. A Session depeands on a Socket and no sockets are created without a session. Should the Client have a function that creates a Session pubically and a Socket privately? Doesn't it violate the law of demeter?

• ubuntu 9.04 pptp broken after a power failure

  - by kevin42

  I have a small Ubuntu 9.04 router setup as a NAT box and a PPTP server. After a power failure everything except the PPTP server still works. A windows client gets to "registering your computer on the network" but then says Error 742: The remote computer does not support the required data encryption type. I did some research and I think the problem is with the ppp_mppe module. When I try to run 'modprobe ppp_mppe' it hangs indefinitely. What would cause this hang? Any ideas how I can troubleshoot this further? Thanks for the help! UPDATE: I am still having the problem, however I have found some more information. When the first user tries to connect to pptp, the process list shows modprobe sha1 running, and one instance of modprobe ppp_mppe for each connection attempt. If I killall modprobe at this point the next connection attempt works, and everything is fine until the next reboot. I'm planning to do a clean install at some point in the future but I'd really like to get to the real cause of this.
