• USB-keyboard & mouse powered off in windows-7

  - by sinned

  I have a problem with a pc where usb devices are not getting any power as soon as windows starts up (it works in preboot). This pc has no ps/2, so there is no chance for input, also not in secure boot mode. I "tidied up" using sysinternals autostart, so there is a chance I messed something up here, although I'm quite sure I only deleted some old printer drivers from autostart. I do not know how to reset this, I cant even log in because there is no input possible. I could use a linux live cd, but I don't know what to do there because there is no sysinternals from linux into a not running windows... To make things even worse, I have the windows installation completely encrypted with truecrypt, so I haven't even tried windows recovery cd yet. There is no loss of data since I can access the disc with a live-linux, I only want to use it again without resetting up everything. Any suggestions?

• How can I access my mini-pc (RaspberryPi / MK802 / Mele A1000 / VIA APC) via ethernet/wifi without having Monitor?

  - by sky770

  Soon I will be getting my own mini-PC (RaspberryPi / MK802 / Mele A1000 / VIA APC). But I was wondering whether is there any possibility that I can just power up and access my mini-pc's OS by connecting it to wifi/ethernet link and remotely access it over the LAN without actually needing a monitor (throughout the process?) ? I currently own a laptop and need a download box and later will be getting a HDTV for converting to a HTPC :D So, I don't really own a spare monitor now but I do have an extra keyboard and mouse. Is there exists any linux distro for the same? which I can use to directly fireup my mini-pc and hook it up across my LAN to remotely access through my laptop? Any suggestions appreciated :) Regards, sky770

• Windows 7 does not 'wake up' from Sleep mode

  - by the watchmaker

  I'm new to Windows 7, so I don't know if this is normal. When the computer is idle for 30 minutes, the screen goes black and no key pressing or mouse movement will bring the computer out of standby. The computer is still running (fans and hard drive noise) but it will not respond and the screen remains black. The only way to get a response is to press and hold the power button until it goes off, then switch it back on. When it turns on it says "Resuming Windows" and then goes black again. Is this normal? Can the time-out delay be increased? Is there a better workaround than switching the PC on and off?

• Why the different coarse threaded screws?

  - by Luke

  I'm seeing more and more of these screws (pictured below), which are almost triangular. I find I can only put them into Power Supplies and PCI(e) cards in cases, but they will break/strip away if I put them into a hard drive or a standoff for a motherboard Notice the triangular shape on it? On the Root Access chat, I started asking, but no concrete answer yet. I don't assume it's a production flaw, as I've seen hundreds and replaced them with the "proper" round screws. It is coarse-threaded, not fine-threaded (i.e. for a DVD drive or floppy drive). What are they for, and why do we need them instead of the regular round ones?

• Any experience with SATA SAS Interposer Cards?

  - by korkman

  Driven by the current price difference between SATA and SAS disks on one side and the potentially bad behaviour of SATA disks in bigger storage arrays on the other side, I have found so-called SATA-to-SAS interposer cards. Advertised as "seamlessly adding SAS capabilities to existing SATA disk drives", I wonder if anyone here has had some experience with these or similar products. The major benefits I can identify are the increased cable voltage (if all drives are SAS connected), the ability to power-cycle the drive and multipath (if desired). Obviously the SATA drive will still have to be RAID edition. The question is: Do these cards indeed increase the overall reliability of a storage system, or will failing SATA disks cause trouble nevertheless? Edit: I'm not asking for hypothetical answers, only actual experience please. I'm well aware that the typical 10k SAS drive is more reliable (and better performing) than 7200 SATA drives. But how does a nearline SAS, which is phyiscally the same disk as its SATA counterpart, compare to the SATA version with interposer?

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

• Random shut down? Asus N53J Laptopi

  - by Mr.Y

  My Laptop is pretty new and today it random shut down on its own. I was surfing the net and the computer shut down on its own (Like losing power, without any warning). It was the 2nd time, the first time was 3 weeks ago. Btw it happens during cold days. I remember one time I was unable to turn on my laptop at all. So I'm pretty sure it's not related to heat issue... could it be the laptop is too "cold"? My room temperature is around 17=18 degree on average :P edit -I use Windows 7 Professional. -I run memtest86 once and it passed. -I run my laptop WITHOUT battery all the time.

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• Wake up my company computer from a home computer

  - by Darcy

  I would like to learn if it is possible for me to send a packet (a magical one) from another computer to my computer. I am interested in waking up my computer at work from the one I am using at home. That is I would like to power it on at 7:00am by sending it a wake-on packet from the home computer. I have no idea how to carry out this seemingly trivial task, I hope someone could offer some basic ideas for me start. Thank you so much in advance.

• VirtualBox CPU usage 100% on host

  - by Sarveshwar

  I have installed VirtualBox 3.1.2 (latest) on my Windows 7 (x64). In the VirtualBox I've installed Windows 7 (x64). I have 4 GB RAM installed. The guest has been assigned a 1536 MB RAM. Sometimes the CPU usage on the host goes 100%. It happens everytime, in a few minutes, after starting the guest. Then it stops responding. Then I have to "power off the machine" from the menu without doing a proper shutdown. It happens with Windows XP as guest too (even when the RAM amount assigned to it was the same). What is the problem?

• Forgot to unmount/eject external hard drive, lost moved files. Mac OS X

  - by balupton

  So I was using my Mac with my external hard drive connected via USB. I moved about 10 GB of data to it (via drag and drop while holding down the Command key to move the files rather than to copy them). They moved to the drive all right, but as I was having some issues and the Finder crashed after the transfer, I was unable to eject the volume and later everything froze so I had to do a hard restart (hold the power button). When I remounted the volume (plugged the external hard drive back in) it no longer had any of the files which I moved onto it. As it was a lot of data, how can I recover these files?

• How do I fix the display of Windows 7's Control Panel?

  - by kez

  This has really bugged me since I took the plunge and upgraded to Windows 7. I think everything is great on the whole apart from the Control Panel. Instead of ordering from top to bottom like in normal folders, it is ordered from left to right. Whenever I go to find something in Control Panel it takes 3 times as long because I expect to find Programs and Features below Power Options yet it is to the right. This is a screenshot to demonstrate - note the ordering goes across instead of down. My question - does anyone have a cunning fix to display the Control Panel ordered in the same way that normal folders are displayed?

• Using VLC to Unicast High Definition Webcam over local gigabit LAN with low/zero delay

  - by Robin Day

  We're setting up a webcam "window" between two offices in the same buildilng. The two PC's are connected to the same gigabit switch. We're using VLC to stream the webcam over HTTP using the following commands. vlc dshow:// :dshow-caching="0" :dshow-size="640x480" :sout=#transcode{vcodec=h264,vb=0,scale=0}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep vlc http://192.168.0.1:8080 :http-caching="0" Even with the caching set to zero, the delay in the image is a good 2-3 seconds. The CPU usage of each pc is also maxed. I'm guessing it's the transcoding that's causing much of the delay. Can anyone give me some changes to these command lines that will reduce the transcoding power, or send the webcam over a different protocol, or anything that will reduce the delay of the cameras? Bandwidth is not an issue at all as the pc's can be connected to a dedicated switch/vlan if required.

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

• How can I use mobile network account at server so home sync works

  - by Mike Gallagher

  I would like to be able to use a mobile network account while sitting at my server. I had os x server 10.6 running on a mac mini server but recently got a new quad core iMac and want to take advantage of the extra power. My problem - I can sit at the server and log into the mobile network account but can not get it to sync back. When I attempt to sync it get error message that the afp share point is unavailable and that the files are hosted locally. My goal is to be able to use the new iMac as the server and set a user account so that it remains synced so when the account is accessed from other clients, particularly my macbook pro. Is mobile account the best route? Would an external account be a better option. Any advice or ideas of where to read up on this would be much appreciated.

• RAID 1 not performing as expected

  - by Faken

  I recently bought a new 320Gb hard drive for my computer to set up RAID 1 on it for some added security. Installation went as smooth as could possibly be (plug in power, plug in data cable, start up computer, Intel software recognized new drive, right click create RAID 1, done!). However, for some inexplicable reason, I seem to have strange test results when using BENCH32. On my old configuration, a single 7200 rpm drive, I achieved about 60 MB/s write and 70 MB/s read. With a new RAID 1 configuration, I would expect the write to be slightly diminished but read to be significantly improved (though not exactly double speed). However, with the new configuration, I am getting 90 MB/s write and only about 80 MB/s read. I should NOT be getting improved write performance, especially NOT better than read! What's going on? My system setup is: q6600 2.4ghz CPU 4Gb DDR2 667mhz RAM on board Intel ICH9R "RAID chip" 2x Seagate 7200 RPM 320GB drives in RAID 1 Widows 7 home premium 64-bit

• HP dv9000 Vista laptop won't boot from CD/DVD drive

  - by ScottEdwards2000

  My HP dv9000 Vista laptop recently got the BSOD with error 0x0000c1f5. The only way to fix this error is to be able to boot from CD/DVD and use some repair software I have. The problem is that the laptop REFUSES to boot from any CD/DVD I try. I've changed the boot order so the CD/DVD is first, and I can hear the drive spin up a bit upon power-up, but after a second, it spins down and then the laptop tries to boot from hard drive. Any ideas? (I've tried lots of CDs so it's not the media itself) Thanks much!

• automated printouts from a wireless printer

  - by Piotr

  I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

• Which software to use for RAMDISK on Windows 2008?

  - by Tony_Henrich

  I am building a server machine with lots of RAM. At least 16G. I am planning to put my frequently read and written data in RAM so I am looking for software for creating RAM disks. This is for Windows Server 2008 R2 Standard 64bit. Any recommendations? I would like one where I can flush the disk image into persistent storage upon demand. For example when Windows shuts down. (I am aware of all the consequences of data loss when power is lost)

• Streaming audio to headless linux box

  - by Ralph

  I have a dual boot (Win 7 + Ubuntu) PC connected via wifi with my music collection on a local HDD. I usually use Rhythmbox on Ubuntu or Winamp on Windows to listen to my music but I'll change if I have to. I also have a Raspberry Pi (low power PC running Debian) in the living room that is usually headless and connected via ethernet. The Raspberry Pi is also connected to my living room speakers via an amp. I would like to be able to stream music from my PC over the network to the linux raspberry pi. What software can I use to do this? Some sort of audio client\server?

• Free alternatives to vSphere for ESXi (if one exists)

  - by Tim

  Dear All, Am feeling a touch confused and overwhemled. From what I gather even though ESXi is free I will only be able to manage my VMs (create or power on etc) for 60 days unless I buy a licence for vSphere. This is somewhat frustrating. As I am looking for a home lab to practice for various certs I was hoping to also practice using vmware stuff to do so. Have I got the wrong end of the stick? Is there a free built in web interface like there was with VMServer or is the only option vSphere (which is massively out of my price range)? Looking forward to your responses and hoping that I have just missed something obvious! Regards Tim

• Connect through SSH and type in password automatically, without using a public key

  - by binary255

  A server allows SSH connections, but not using public key authentication. It's not within my power to change this at the moment (due to technical difficulties, not organizational) but I will get on it as soon as possible! What I need now is to execute commands on the server using plain old account+password authentication from a script. That is, I need to do it in a non-interactive way. Is it possible? And how do I do it? The client which will be executing the script runs Ubuntu Server 8.04. The server runs Cygwin and OpenSSH.

• Software for capturing still image snapshots from video input

  - by cantabilesoftware

  What software is available that will let me watch video from a USB video capture device at full PAL/NTSC resolution and capture a still image at a button press? More info: I'm using a KaiserBaas USB capture device (http://www.kaiserbaas.com/kaiser-baas-product-page/converters/video-to-dvd-maker), and want to capture screen shots from a PS2 connected to it. I'd like to play the game at the full PS2 resolution and capture certain scenes. The device has a one-touch snapshot button on it, but I can't seem to make it work and there's no mention of it anywhere in the documentation. The device works and the video appears in Power Producer (the included software), but I think it previews it smaller than the full resolution. I could print screen it, but having to crop will be a pain.
