  • Apple Service Diagnostic application on USB key?

    - by Matt 'Trouble' Esse
    I found the following in a text file, and I would like to use the Apple Service Diagnostic Application from a bootable USB key but I cannot find where to download it or set it up? Also is this free software or does it require a separate licence? It sounds like it would be a useful tool for diagnosing Mac problems. The Apple Service Diagnostic application is designed to run both EFI and Mac OS X tests from an external USB hard drive. Apple Service Diagnostic (EFI) runs low-level tests of the hardware directly and does not require Mac OS X, while Apple Service Diagnostic (OS) uses Mac OS X to run tests. Booting and Using the Apple Service Diagnostic Application - Before using Apple Service Diagnostic, disconnect any Ethernet network, USB, and audio cables. - With the USB hard drive containing ASD 3S123 plugged into a USB port, restart the computer and hold down the option key as the computer boots up into the Startup Manager. To run ASD (EFI) select the "ASD EFI 3S123" drive icon and press return or select it with a mouse click. To run ASD (OS) select the "ASD OS 3S123" drive icon and press return or select it with a mouse click. ASD (EFI) will load in 20-30 seconds; ASD (OS) will load in 2-3 minutes. - After running ASD (OS) or ASD (EFI), press the Restart button to restart the computer back into the normal startup volume, or hold down the option key to get back to the Startup Manager. ASD is no longer delivered as an image to be restored onto a DVD. ASD 3S117 and newer versions requires installation onto an external USB hard drive. For more information, please refer to the document "Installing ASD on a USB hard drive".

  • Acer aspire 5520 power light blinks no boot

    - by Shawn Mclean
    My laptop was working fine last night, I hibernated it and went to sleep. Got up, pressed the power button. The power light comes on for 4 seconds and the hdd light blinked a few times, then it turned off for a second then repeats the process. The only way to stop this process/power down is to remove the AC and take out the battery. It does not even reach a boot screen, nothing shows up on the screen, fan does not start. People on this forum has the same problem but they suggest to put the laptop in a oven and heat it (reflow). What could be the problem? Is there another solution other than a reflow? I dont feel like putting my motherboard in the oven.

  • How do I increase my home's bandwidth?

    - by Derek
    I just mistakingly posted this on Stack Exchange but don't know how to delete it... Anyway, I was thinking of building a home server to use instead of renting a VPS, because in the long run it would be cheaper. What I'm concerned with is the bandwidth limit of my house. I know when I'm downloading something off the internet, if I download at high speeds the rest of the computers connected to my router will become slower. Is there any way to avoid this? There are other cable outlets in my house, will connecting a modem and router there avoid this problem?

  • YouTube videos not working

    - by André
    I have a problem with watching YouTube videos. It says: "An error occurred, please try again later". I've tried loading different videos and that's what it says to all the videos I try to watch. I've tried using another browser, clearing cache + cookies etc, but none of that really worked out. My operating system is Windows 7 Home Premium, I use Google Chrome as my browser. And the YouTube videos was able to be watched earlier. I suspect that it has something to do with the PC, since I've got YouTube working on my laptop earlier. Not sure if it still works on my laptop though. Hope I've given enough information for you to help me out with this problem. Feel free to ask if there's anything else you need to know. Hope you can/will help me out. :)

  • BackTrack5 R2 video driver works, but presents disturbing error message

    - by poz2k4444
    I've installed backtrack 5 R2 on my computer and everything works fine but the video driver. The solution described here does work, but whenever I start the graphics mode, a message saying that the graphics card doesn't support the configuration that is loaded. I don't know why this is happening. It doesn't change the performance of my computer, but I'd like to know why the message is arising, and what I can do to stop it. Alternatively, where can I find the configuration file that would help me understand what's going on?

  • Follow cursor location from kile to evince.

    - by D Connors
    I know the title is probably not very clear, so I'll try to be as clear as possible here. I'm running xubuntu on my netbook, and I'm using kile for my latex editing. Since kile is native to kde, I had to manually set it to open pdfs and dvis on evince instead of okular. Now, last time I played around with LaTeX I was using TeXnic center on windows, and it had a very neat feature. Whenever I hit "QuickBuild", not only would it open the output .dvi file, but it would also show me exactly the piece of text I was editing. That is, if I were editing line 13 of the 7th of my document, when I compiled it, the dvi viewer would automatically take me to line 13 on the 7th page of the document, so I wouldn't have to scroll all the way down to it every time I compiled the .tex file. I'm guessing this is a pretty standard feature, and kile probably supports it. But since I don't know what it's called, I'm trying to be clear as to what I'm talking about. Problem is, this feature is not working for me right now, and I'm guessing it's either because evince does not support it, or because I have to manually configure it. Which one is it? And how do I manually configure it, if that's the case?

  • insert null character using tamper data

    - by Jeremy Comulu
    Using the firefox extension tamper data (for modifing http requests that firefox makes) how do I insert a null character into a post field? I can enter normal characters, but binary characters in it are not urlencoded and are shown as is, so how do I enter the null character into a field? If you know of a firefox extension like tamper data that I can do this or a way to do this using tamper data please post.

  • Test whether svn REPO changes are reflected in Working Copy

    - by user492160
    Requirement Changes will be made to the REPO directory and this should get updated to wc(working copy) as opposed to the normal way of WC REPO. Senario: My svn repo- /var/www/svn/drupal My checkout-dir/working-copy- /var/www/html/drupalsite So I've done: edited post-commit hook to contain: "/usr/bin/svn update /var/www/html/drupalsite" I won't make any change to svn WC. I'll make changes to svn REPO- /var/www/svn/drupal. After changes are made to svn repo, run "svn commit /var/www/html/drupalsite". This will trigger the post-commit hook. This inturn will run "svn update /var/www/svn/drupal" and thus my WC will get updated with the changes of REPO. Query a. Would the above steps 1-3 help achieve my 'Requirement'? b. I'd need advise on how to test if the above setup works successfully or not. I'm at loss about the success of steps 1-3 the reason why query(a) is present. This is a bit more of a concern for me. NB: I'm new to subversion. Whatever I've configured till now have been done by reading articles online. Reason for query (b) is because I'm not into development. It seems to be a php drupal website and I happen to be setting it up. So I'm not aware as to how to make a "PROPER" change in REPO so that it gets reflected in WC. If reflected, my configs are right and the team can start on development. I manually put a random file/folder into REPO dir for seeing a change in WC and ran steps 1-3 but was of no avail and later on learned that it was NOT the way to make a change to a REPO. Pleas advise. Thanks

  • Arch linux selecting packages

    - by allenskd
    Hello, I'm currently having problems with my arch linux installation, forgot to select a few packages but in the guide they never mention which key do I need to press to select/deselect the packages in the installation screen. I used to select them but it's been a long time, I don't remember much anymore =/ Or, if there is a way to make pacman recognize the cd as a container of packages that'd be great.

  • Windows 7 installation: drive selection doesn't show drive letter

    - by FrozenKing
    I am eager to get this answer i.e. in Windows 7 when we format the computer there is a problem that when we have to select drive for formatting, it doesn't show drive letter. *I need a solution wherein when I format I want to know its drive letter so that I may not be confused while formatting. *See the difference between windows xp and windows 7. I want windows 7 to show drive letters like windows xp. Does any one know why windows 7 doesn't show drive letters.

  • locked files on HFS+ home partition shared between OSX/Linux

    - by HazyBlueDot
    I dual boot into Arch Linux and OS X 10.6 on my MacBook pro. I synced my UID between both OSes and created an HFS partition (with no journaling) to use as a shared home/Users partition. For the most part it works just as I'd expect, but sometimes when I'm booted into OS X certain files are "locked" (when I get info on a particular file the "Locked" box is checked under the "General" pane. I can resolve the issue by manually unchecking the box) and/or I get "Operation not permitted" when I try deleting or chmod'ing a file. In both cases I don't see anything out of the ordinary on the permission bits displayed with ls -l, except for a trailing '@' character in the position where the sticky bit would normally occur: -rw-r--r--@ 1 myuser mygroup 296 Mar 29 11:44 myfile This '@' character shows up on ALL normal files, so doesn't seem to be linked to the locked/operation not permission situation. On the Linux side of things I never have permission problems. To the best of my limited knowledge and experience with ACLs I've not found any ACLs on any of the files in question. For what it's worth, I do most of my file editing using emacs (Aquamacs in OSX), is it possible it is setting weird permission bits? What is the "locked" setting that OS X uses and does it have a permission bit equivalent (so at the very least I could recursively unlock all files in my home directory from the terminal) why might some, but not other files get "locked" when booting into OS X what is the meaning of the '@' character?

  • How to deal with lots of brackets in a formula?

    - by wenlibin02
    Say, I have a formula like this (in LaTeX or Maple or other text system): Result: ((6*(k2+k3))*A123*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2+6*A12*(-k3+k2)*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*(exp(-k2*(k2^2*t-x)))^2+(-(6*(-k3+k2))*A13*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2-(6*(k2+k3))*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*exp(-k2*(k2^2*t-x)) Note: the above formula is only one part of the result of a maple calculation, I just can't break them up because there are so many many terms. Apparently, It's very hard to read. What I want to do is to fold the matched brackets level by level. If all the brackets are folded, I can find out clearly how many terms there are. Then I can analyze from the top level to the details of every term. But I just don't know how to realize that. Maybe there are some existed software which can visualize this kind of complex formula. Any idea? P.S. I use Linux system. The open source alternatives are better.

  • Equations saved from Word 2007 for Windows do not appear in Word 2008 for Mac

    - by user36081
    I am a math teacher who uses Word 2008 on the Mac, and I need to collaborate with other teachers who are using Word 2007 under Windows. When they send me a document with mathematical equations in it, I can open it but not see the equations or the document loses formatting such as superscript for exponents. On this page of Known Issues in Word 2008, Microsoft says, Equations saved from Word 2007 for Windows do not appear in Word 2008 for Mac Equations saved in Word 2007 for Windows are not supported in Word 2008 for Mac. The equations will be preserved so that they display correctly in Word 2007, but will appear as placeholders in Word 2008. What can I do to collaborate with users of Word 2007 on mathematical documents?
