• UPS recommendations for three grey boxes?

  - by Margaret

  Hey all We have a series of grey-box style computers acting as servers at my workplace (rather than rack-mount). We were looking to get Uninterruptible Power Supplies for them. However, I'm not sure how many at what capacity are required. I'd assume it would be a good idea to hook the peripherals in as well - there's a 18.5" LCD monitor with a KVM, along with a couple of USB hard drives that require power. I currently have the most vital machine hooked up to a cheap (temporary) UPS, but it's probably close to worse than nothing. I'm looking for reasonable value for money, though I can probably negotiate with my boss on price range. I recognise that I may well need to buy two (or even three) UPSs to support the three machines. Any recommendations?

• Is it possible to mount a hot-swappable drive when it is turned on?

  - by John

  In my PC, I have a hot-swap drive. Usually I keep it off to save power. I only really use it when accessing from another PC on the network. Is it possible to configure /etc/fstab to mount this drive when I turn it on (without having to shake the mouse, open file manager and click the drive to have it mounted? Currently, I have: UUID=a869e5ca-7d3b-4d64-91e2-eadbecd8c9e5 /media/i-TVShows ext4 rw,nosuid,nodev,auto,user,uhelper=udisks 0 0 in my /etc/fstab file but it doesn't seem to do the trick. I want the drive to be user-mountable, on power on, with RW access, and I'm thinking of adding 'nofail'...this is my first time writing to the fstab file, and a lot of the parameters I took from the output of 'mount' so feel free to correct any oddness you find. Thanks

• Dual boot OSX and Windows 7 natively

  - by Phill

  I'm considering getting one of those new fancy Mac Book Pro's with the fancy screens, but after reading some stuff on the internets about running Windows 7 with bootcamp: https://discussions.apple.com/thread/2770866?start=0&tstart=0 It seems you can't use the integrated graphics with windows, this causes windows to chew the battery life: I am afraid it is not possible. Since Apple introduced dual graphics chip laptops, they kept the low power/embedded GPU hidden under Window and they expose only the power hungry discrete GPU. It feels that this is being done on purpose so that it appears to users that OS X offers a better experience and battery life over Windows. So running bootcamp and windows kills the battery, running in parallels means you don't get accelerated 3d support (or something along those lines), so you don't get the performance out of it. I'm wondering: Is it possible to natively dual boot Windows 7 on a MBP, and if so would/does that give windows access to the integrated graphics to be able to not rape the battery?

• Mini-ITX board for AM3 Athlon X4 600e processor.

  - by Kamil Zadora

  Hello, I am planning to build a PC to control a robotic platform that I am building (about 50% complete). I need more power than ATOM platform could bring, as the robot will need to do on the fly image processing to work as intended. I was considering using Athlon X4 600e as it is rated 45W Maximum output. Probably underclocked it would go lower than 30-35W. I do not I'am at very long battery life, but the 17Ah, 12V battery should keep it running for few hours. My problem is: motherboard. I am space limited so I am looking for a nice mini-itx AM3 motherboard to match the processor. It is hard to find many tests about power usage of the motherboards itself (for example, when using the same processor on different motherboards, test are usualy done in the opposite matter). Could you provide any motherboard examples or suggest what chipset to look for? Thank you in advance.

• Why my widows 8 pc always powered on by moving mouse?

  - by Shinbo

  I recently installed windows 8 RTM, but found a very annoying thing. My PC always powered on automatically even in midnight. Eventually I noticed that I can power on the PC by pressing keyboard or mouse, and even moving mouse. After searched this in google, I turned off Sleep and Hibernate in Power Options - System Settings - Shutdown settings, but it still did not work. Would anyone please help me? I don't want to suffer from the noise of PC powering on in midnight any more. Thank a lot.

• Recover Intel Matrix Raid Configuration

  - by Catalin DICU

  Hello, I had 2 HDDs in Intel Matrix Raid configuration on a motherboard with intel ICH9R. I had some RAID 0 partitions and one RAID 1 partition. Somehow when replacing my videocard I partially unpulugged the power connector from one of the HDD. I booted and only one disk was showing. So I turned off the PC and correctly plugged the power connector and how both HDDs are showing as "Non-Raid Disk" Is there a way to restore the raid configuration from before ? In fact I don't really remember how my partitions where configured, I had 2x100Gb + 1x296Gb in RAID 0 and one 50Gb in RAID 1 (using 2x320Gb HDDs) but I'm not sure how many volumes and how the partitions where allocated on the volumes. Is there a tool to find that ? Thanks

• Unpredictable MBP wake from sleep in Windows 7 Boot Camp

  - by qntmfred

  I have a Macbook Pro with Windows 7 installed in Boot Camp. I have serious problems with waking from sleep 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 often end up having to press the power button just 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 (and gives me the Windows did not shut down properly message). Is this a common problem with Boot Camp? Can I fix it?

• Installing XP through USB-to-IDE/SATA connector?

  - by overtherainbow

  Hello To help someone reinstall a corrupt XP install on his IDE or SATA drive in a older desktop box (hence no Vista/W7), I was thinking of asking him to bring his harddrive and meet at Starbucks, and I would install a brand new XP by connecting it to my laptop, and booting it up with the XP install CD. If someone's already used a USB-to-IDE/SATA connector such as this one by Sabrent: Does the XP CD accept installing Windows to an external IDE/SATA through USB? Does USB 2.0 provide enough power to run an external IDE/SATA drive, or do I need to provide the drive with its own power (in which case, how?)? Thank you.

• Can Resource Governor for SQL Server 2008 be scripted?

  - by blueberryfields

  I'm looking for a method to, in real-time, automatically, adjust Resource Governor settings. Here's an example: Imagine that I have 10 applications, each hitting a different database on the same database machine. For normal operations, they do not hit the database very hard, so I might want each one to have 10% CPU power reserved. Occasionally, though, one or two of them might spike, and run an operation which could really use the extra power to run faster. I'd like to be able to adjust to compensate (say, reducing the non-spiking apps to 3%, and splitting the difference between the spiking apps). This is a kind of poor man's method of trying to dynamically adjust resource allocation and priorities. Scripts (or something script-like) is preferred, since the requirement is for meta-level adjustments to be possible in real-time, also.

• Random flickering on 2.6.32 kernels after suspend

  - by whitequark

  I have XUbuntu 9.10 installed on a Toshiba NB200 netbook with Intel video card that's handled with i915 driver. With 2.6.31 stable, recommended kernel everything but WiFi works fine: Atheros ath9k WiFi shows too small signal power and loses packets in 'bursts' sometimes. With 2.6.32-* (I tested -9 to -11 from Ubuntu's kernel unstable ppa) everything works fine just prior to first suspend: echo mem >/sys/power/state. After it random unidentified fullscreen 'one-frame' flickering begins in Xorg, and after a couple of minutes everything eventually hangs while showing filled grey (not white; it is like default button colour) screen; no X keys are working: Ctrl+Alt+Fn don't, blind typing in console too. Magic SysRq still works and I was able to reboot. Also there is one out-of-tree kernel module called omnibook that is required to turn on WiFi and Bluetooth. Any advices?

• Dell Dimension 2400 problem

  - by murgatroid99

  I have a new problem with a Dell Dimension 2400 PC. Until yesterday or the day before, it was working fine, but today when I press the power button the light on the power button turns yellow instead of green, the fan behind the processor increases speed until it sounds like a jet engine, and the computer does not boot up. I cleaned out the dust in the computer so that is not the problem. Also, the fan was blowing cold air. Do any of you know what might be causing this and how I might be able to fix it?

• Does the retina MacBook Pro Australian charger duckhead have 3 prongs on it or 2?

  - by frenchglen

  I notice that with my Retina MacBook Pro (bought in UK), its charger uses all three prongs to power the laptop (like this, rather than this). Not surprised, it's a powerful machine. I'm going to Australia now and I want to use an aussie duckhead and make use of the innovative design. I have an existing one from an old iPod (and it used to work with fine with my Macbook Air when in australia), but it's only two prongs (like this). Is that enough to power my rMBP? Or will it damage/strain it and I need to find a 3 prong one (if it even exists - I haven't bought my MBP in Australia) like this? Thanks

• iMac goes black, makes clicking sound... thoughts?

  - by Josh

  This is the second time this has happened. The display on my Apple iMac (20-inch Late 2006) just went black, system was completely unresponsive to mouse/keyboard input, I could not SSH into nor ping the machine, and it didn't show up in ARD. I could hear a fairly loud clicking noise from inside which sounded like the DVD drive trying to seek -- but there is no disc in the drive. It could possibly be the hard drive... I pressed the power button and the system powered off, and now will not power on again. Thoughts / suggestions as to next course of action?

• xorg DPMS off: keep VT from turning screen back on

  - by Metiu

  I have an embedded board with a small UPS. When AC power goes down, I need to turn off all power hungry devices in order to have a clean shutdown. First thing I do, is set DPMS to force powerdown, then go through the usual SIGTERM/SIGKILL/umount sequence. I have an Intel i915 Display adapter connected to an LVDS LCD panel. Unfortunately, when Xorg dies, Xserver or the VT code turn the LCD panel back on. I even tried working around it by directly poking the panel enable register in the Display chip, so that X doesn't know about it, but the panel goes back on when the VT comes back. Is there any "legal" way of keeping the display off? Thank you

• ThinkPad T400 backlight doesn't always turn on when booting from battery

  - by srunni

  I have a Lenovo ThinkPad T400, which I've owned for about a year. A while back, I noticed a problem in which the LED backlight would not always turn on when booting from battery. Usually, if I hold the power button down until the BIOS screen shows up, the backlight turns, but sometimes even that doesn't work. If I just press the power button and let it go right away, the backlight usually doesn't turn on. This happens before the OS (I dual-boot Linux and Windows) gets a chance to boot - the BIOS screen itself is displayed without the backlight if it fails to turn on, so the problem isn't at the OS level. Any ideas? Thanks!

• Laptop not charging when connected to mains outlet

  - by Josh

  I've had this laptop for a few weeks now, it's a Sony Vaio. I went to charge it a few days ago and plugged in the power cable, but it's not charging. The battery icon in the Windows taskbar to the bottom right says it's plugged in and charging, but the charge level never goes above 2%. I have checked and I don't have a hcarging switch on the laptop anywhere, so it should be charging. If I unplug the cable, the laptop runs out of power within 30 seconds or so, further fueling my thought that it's a faulty battery. Anyone have any bright ideas? If this doesn't get fixed I'll just ring up Sony and get them to send me a replacement battery or something. Thanks.

• Lockup when unlocking screen saver

  - by chris

  I've had this happen a couple of times - screen saver kicks in, locks the screen, and when I put my password in to unlock it the system just seems to hang. Cursor turns to the busy, HDD light flickers occasionally, but the only thing I can do at that point is power down. This is on a desktop, not a laptop and according to the bios all the power saving is turned off. Has anyone else seen this? Is there a way to prevent it, or at least diagnose the cause?

• RAID5 on SmartArray P410i online resize

  - by datacompboy

  I have P410i+256M Cache without battery backup. My RAID5 was build over 3*136GB disks, now all disks were replaced to a 3*300GB array. How can I extend it to use the whole space? HPacucli doesn't allows that, I think this might be because no battery is present. I have a redundant power supply. All data is mirrored over DRBD to a secondary server, so I can try to resize with a chance of loss of data in case of power failure, but I prefer to have an online resize.

• ESXi 5.1 on Poweredge 510 freezes after base-esx update

  - by goober

  Background / Problem Just experienced an issue where an ESXi host was upgraded from 5.0 -- 5.1 perfectly fine. Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully. However, on reboot, the server hangs at the "Initializing Power Management" phase. I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :) Question Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?

• How can I create and add a new slide type to the New Slide menu in PowerPoint?

  - by ObligatoryMoniker

  On the Home ribbon in Power Point 2007 there is a new slide button with an arrow that shows you various types of slides that you can add to your presentation: Title Slide, Title and Content, Comparison, Title Only, etc. I want to design a new type of slide that has 4 content areas instead of two and then be able to add new slides of this type using the new slide menu. I know that I can add new Power Point templates but that would require me to start a new presentation with my custom slide type in it and the copy and paste that slide into the current presentation that I am already working on. How can I create a new slide type and then add it to the menu so that I can quickly create new slides of my new 4 content area slide type?

• How to keep Windows 7 from sleeping while scanning the PC.

  - by D Connors

  So, I've been using Microsoft Security Essentials lately. And it usually takes a couple hours or more for it to full scan my hard drive. Because of that, I commonly leave it scanning while I go do something else. Problem is: 10 minutes later, windows 7 goes to sleep, and the scan is (obviously) paused. That's What I'd like to stop happening. So far, the only way I've been able to avoid it was to create a power plan, and switch to it while away, to keep the PC from sleeping. Problem is that I have to keep switching power plans and I'd like the PC to be able to go to sleep in case MSE finishes scanning and I'm still not back. Maybe I'm just asking for too much, but I've been surprised by the users here plenty of times already. So let me know if you know how to keep the PC from sleeping while MSE is scanning. Thanks

• Setting up a home server - what to use? (ZFS vs btrfs, BSD vs Linux, misc other requirements)

  - by monch1962

  I need to get all our home content off individual machines and onto a central server. What I'd like to have is the metaphorical "server under the stairs". Stuff we need: expandable storage. I want to be able to add extra disc as we go along, with minimal maintenance required. Currently we've got about 3Tb of files we need to host, and that's likely to grow by another Tb every 6-12 months based on recent history. I need to be able to add additional disc with minimal pain needs to store all the media (i.e. photos, video, music) we have, and run services to serve the various devices we have in the house to playback (e.g. DAAP so we can play stuff through iTunes, ccxstream so we can play stuff over XBMC). DAAP and ccxstream are needed now, but we also need to support new standards as they emerge (so a closed-box solution isn't going to work) RAID 5, or something broadly equivalent (e.g. RAID-Z) BitTorrent client ssh, NFS, Samba access snapshot capability (as in ZFS), so we can snapshot individual file systems regularly and rollback when my kids delete their school assignments the day before they're due... ability to recover quickly from power outages (it's not unusual for us to have power outages that last longer than our UPS' batteries) FOSS software a modern distributed version control system running on the box, such as Mercurial Stuff I'd like to have on the server, but can live without: PVR capability, so I could record TV to the box Web server. We currently run a small Web server on a very old box, and I'd ideally like to turn the old box off and move the content to the new server just to save some electricity Nagios + mrtg I've been looking at using a EEE Box as the server, primarily because I can get them cheap and they don't consume much power. The choice of OS and file system is more difficult, from what I've found: I've got most experience with various Linux distros, but am happy to use another Unix FreeBSD and OpenSolaris seem to be the best choices for hosting ZFS OpenSolaris' hardware support is nowhere near as good as e.g. Ubuntu btrfs, while looking very good, doesn't seem ready for prime-time yet ZFS doesn't let you (easily?) add new discs to a RAID5 or RAID-Z reading around, it seems that ZFS is a bit short of tools for recovering lost data At the moment, I'm leaning towards running FreeNAS+ZFS, but I'm concerned about the requirement to be able to add new disc on a fairly regular basis to an existing RAID-Z. Can anyone provide some recommendations, or share experiences? Thanks in advance
