• IBM BladeServer Chassis compatibility

  - by Matt

  Hi, I'm looking at buying a 3 year old blade server. My question is, if I buy it and want to insert a current model blade, will it fit? Also, if the chassis goes "POP" and I need to replace it, will the current model chassis fit 3 year old blades? What about Power supply replacements? The chassis I'm looking at is this: IBM FRU / PN: M8677-3XM with DVD reader The blades are all IBM HS20's. We've had a good run with IBM hardware and although there is some nice ex-lease HP hardware available, my understanding is that backwards comparability is not so well maintained. Is this true?

• Can a Double-Density Floppy drive be swapped out for a High-Density drive?

  - by Ben

  I'm trying to fix the floppy drive in my Roland MC-500. The floppy drive inside is a Matsushita DDF3-1 which doesn't seem to be in production anymore. The DDF3-2 is still available, however it is an HD drive. Does anyone know off the top of their heads if there is any issue with simply swapping the two drives? Could the power usage be different on the drives? Since the machine is expecting a 720k DD drive, are there any jumper settings to have the HD drive function as a DD drive?

• Run a program in compatibility mode without Administrator privileges

  - by a_m0d

  I have a PC which is mostly used for playing games. The PC is a few years old, running XP, and most likely won't ever be upgraded to Windows 7. However, there are a few games that need to be run in compatibility mode for some reason, and this currently requires them to be run as the administrator. Unfortunately, I haven't found any way around this - although I have the administrator password, I don't want to reveal it to the others who use the PC, and this means that I have to be present every time to start the program for them (using Run as ... - Administrator). Is there any way I can allow these programs to be run in compatibility mode without requiring elevated user privileges? I have already made the standard user a Power User, but this hasn't helped at all. Any advice would be appreciated.

• Good, secure video chat program

  - by wag2639

  I'm looking for something similar to skype but basically just for me to video chat with my girlfriend. Skype has been kind of buggy lately with its recent iterations and doesn't seem to be progressing as much as when it was with its previous backers. Are there any good, secure video chat programs? Something that customizable and lets you choose framerate vs pixelation and is generally secure (I don't care if the NSA can tap it but no one else, especially over unencrypted wifi's). Open source is preferred but not required. Free or really really cheap is practically required. Also, since this is point to point, an i am a power user (and my gf as well), it can involve some manual setup to establish a point-to-point link. Any suggestions, Thanks.

• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• rundll32.exe constantly running taking up resources slowing down my Win 7 computer

  - by Joe Fletcher

  Over the past week, my Windows 7 Home Premium computer (8gb RAM, 64bit) has been running slowly. When I look at my processes, there are always 2 rundll32.exe's running taking up 3 & 25% CPU power, memory slowly creeping upwards from around 115mb to 160mb each in the time it has taken me to right this message, sometimes popping upt o 300mb and back down. Svchost.exe is at 260mb. When I end those processes, everything returns to snappiness. I recently did some Windows Updates, and I think it was around the time my computer started acting slowly, but I can't remember if it was before or after the updates that things started running slowly. Last night I ccleaned & defrag'ed. How can I diagnose what's causing the slowness?

• MacBook Pro shutting down instantly after attempt to update firmware

  - by Luke Dennis

  I tried to apply a firmware update on a MacBook Pro 2.4ghz (2008), and after rebooting, the fans kicked up to maximum, the screen lit up, and then it immediately died. Now when I try to boot, it does the same thing: the fans crank to max, the screen lights up, and then it dies after about 2 seconds. Resetting the power manager does nothing. It doesn't stay up long enough to choose another boot drive or boot from CD. I have no idea what else to try. Help?

• What is Light Peak

  - by Jonathan.

  I've heard this a lot recently, todo with Apple and Intel. Some says it's a protocol, others say it's fibre optic, and others say it's copper. One source even said it was a "wireless wire". Apparently it can carry data, but not video streams, surely the cable can't know the difference between 1s and 0s representing data, and 1s and 0s representing video streams. Or it will replace all the wires we currently have except power, another place said it is for inside laptops. Those are just examples so I haven't given any sources, I just want to know what on Earth Light Peak is?

• Why does my computer slow down so much when attaching Bluetooth dongle?

  - by Jeff Yates

  I have a Bluetooth dongle and I plugged it into my work laptop (a Dell Latitude D830). Windows detects the Generic Bluetooth USB or similar and then proceeds to go incredibly slow with a process, avp.exe¹, taking 50% CPU. The System Idle process is getting most of the other 50% CPU and the avp.exe process is only at Normal priority. The machine doesn't seem to recover, so I had to turn the power off and reboot. Now, I haven't installed the drivers yet for the device, which I am doing now and I expect it to resolve the problem, so I am not asking how to fix this. I would rather know why Windows goes so slow in the first place. What is it trying to do and failing at so badly that it barely crawls? ¹ Part of Kaspersky Internet Security suite

• Can't find a Windows Explorer alternative that has FULL-TREE View

  - by samJL

  I cannot find a Windows Explorer alternative that has full-tree view functionality like Path Finder on the Mac This is the type of view I am looking for (screenshot of Path Finder on Mac): By full-tree I mean: A tree view that includes files in addition to folders, and can be operated as its own pane-- not as a shared pane or attached pane which is characteristic of Q-Dir. Q-Dir and most others simply stick a folder tree pane on to a file list pane, which is not as useful (think Ruby on Rails application or anything with MVC-- I want to be able to pop open folders in the tree and have them stay open as I work between them). I have tried xplorer2 XYplorer Nexus File Free Commander muCommander CubicExplorer Double Commander Q-Dir Explorer++ Unreal Commander wxCommander Power Desk Directory Opus Has anyone seen a Windows app that has a full-tree view? I can't believe such a simple feature is so hard to find Thanks

• My HP-Vista based laptop has become very slow recently

  - by goldenmean

  My HP laptop which has Vista Home premium. When I try to start Firefox, internet explorer, it becomes very slow. No other app. When i checked the Performance in Task Manager. It shows the Physical memory , Free as 0 bytes, almost always. This has been recently. Earlier it didn't used to be zero. Laptop has 2GB of RAM. I have nothing running in my tray except - Sound control, Laptop power plan indicator,Network status indicator. There are no other processes whose memory usage adds up to so high to make Free memory as 0. Then what could be hogging the memory and make the laptop very slow. Any pointers would help as it is crawling at the moment.

• How Often Do Windows Servers Need to be Restarted?

  - by Evan

  A little background: We have several Windows servers (2003, 2008) for our department. We're a division of IT so we manage our own servers. Of the four of us here I'm the only one with a slight amount of IT knowledge. (Note the "slight amount".) My boss says the servers need to be restarted at least weekly. I disagree. Our IT Department says that because she restarts them constantly that's the reason why our hard drives fail and power supplies go out on them. (That's happened to a few of our servers a couple times over the last four years, and very recently.) So the question is: How often does everyone restart their Windows servers? Is there an industry standard or recommendation? Is our IT department correct in saying that because we re-start that's why we're having hardware issues? (I need a reason if I'm going to change her mind!)

• How to stop a Linux LVM volume group?

  - by thkala

  I am currently dealing with a multiple disk failure on a Linux LVM Volume Group that is backed up by a RAID-5 md device. One disk has been taken out completely and another one is showing a limited number of corrupt sectors, due to what seems to have been a misbehaving power supply. The problem is that once an I/O error hits, md takes the array down, since it does not have enough devices for it to be operational. Where md the only one involved, I could mdadm --stop the array and then recreate it to get all devices active again. Unfortunately, the array is a PV in an LVM volume group and I cannot seem to get the kernel to release it. vgchange -an does not seem to do anything, bar spew out a couple of I/O errors. I am obviously missing something, but how in the name of -insert-favorite-deity- do I get LVM to release the underlying PV without rebooting the server?

• SQL Server Agents jobs and turning off the server

  - by Tim Joseph

  I'm really new to SQL Agent jobs, but I am attempting to build up a maintainance regime for a server that will be turned off and on again at unknown intervals. It may run without being shutdown for a month, or it might only be turned on 9-5... we don't know and the client can't tell us because they don't know. So what I'm wondering is, what do I need to do to get SQL Server to run monthly and daily jobs either when they are due, or if the due date is missed, get them to be run when the server is next powered on. I could come up with a mish-mash of periodic jobs and 'on-power-up' jobs, but if there is something more elegant that would be wonderful. Obviously I'll need to ensure the SQL Server Agent is configure to start when the computer is powered up, but what else?

• Linux WD30EZRX WD Green HDD & Blacx Duet 5G Usb

  - by Adam

  I have connected up an WD30EZRX WD Green HDD to a Thermaltake Blacx Duet 5G USB dock in Ubuntu 12.04. Every thing seems fine except when the HDD idles it seems to have error ls: reading directory .: Input/output error after a while and is only fixed by unmounting and remounting the drive as root. I have the following line in /etc/fstab UUID=AAF670E9F670B6E3 /media/3TB ntfs defaults,user,auto 0 0 I have noticed that it seems to go between /dev/sdc2 and /dev/sdd2 devices on remount. I did copy 1TB last night without issue in 1 sitting. But after x mins of idle it has remount issue. Any tips/suggestions on how to proceed would be appreciated. Spent most of the night googling and all its done is made me sad. Edit (tried as suggested): root@mediaserver:/media/3TB# sudo hdparm -B 255 -S 253 /dev/sdd2 /dev/sdd2: setting Advanced Power Management level to disabled HDIO_DRIVE_CMD failed: Input/output error setting standby to 253 (vendor-specific) APM_level = not supported Seems as if that didn't help with this particular drive.

• 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?

• Sudden restart when Ubuntu almost loaded from disc.

  - by Wesley

  Hi all, Here are the specs beforehand: ECS K7SEM motherboard AMD Duron 900MHz 2x 256MB PC133 SDRAM The Best Power MT-500P 500W PSU Integrated graphics No hard drive DVD-ROM - will update with brand & model Now, I was starting up this machine after it was left outside for 3 months in winter weather. (I got this from a friend.) I was able to get it started and tried to load Ubuntu from the DVD-ROM. It was fairly successful and got up to the point when the Ubuntu logo is glowing. However, when Ubuntu was about to go to the main screen, the computer crashed and automatically rebooted. Is there any reason why this is happening? Also, I should mention that when I try to hit Delete on the BIOS screen to go to Setup, it only shows a screen with four lines saying something Novell something... I will edit with exact lines. Should I be resetting the BIOS or something? Thanks in advance.

• Computer not displaying anything

  - by Justen

  The computer in question worked last week. It's brand new, never been connected to the internet, up-to-date parts, etc. Last week, I installed some 3D software on it, then shut it down and waited for the license files that arrived this week. I've done this to 4 other PCs with the same hardware and software. I've tried: Hooking it up to 3 different monitors using different video cables 2 other graphics cards and a handful of other things like switching which port it's plugged into before and after a restart. I have the driver disc, and a windows reinstallation disc, but they won't do me any good because no display at all for any interval of time. All the fans are moving: psu, gfx, cpu etc, so I don't believe it's a power issue. Here are the specs I know of: 4GB RAM 8800 GTX 700w PSU Intel dual core (not sure of model) Anyways, I'm open to ideas.

• is a mini PCIe SSD worth it?

  - by Narcolapser

  Question: Is getting a mini-PCIe worth investing in? Info: I have a an Acer Aspire 1 n270. It has this mini PCIe slot that is just sitting there empty. I would like to change this, and I would like to speed up my boot time. So I've been considering getting a mini-PCIe SSD. They are about the same price as faster same size drives of the 2.5" variation. The advantage of the mini-PCIe card is that I can have my HDD still. So I have good boot time, but still have the storage of my HDD. What I want to know is: will this allow me to spin down the HDD more often allowing me to save power? Will the OS (Ubuntu 10.04 LTS) see them as separate drives? Is there anything that the mini-PCIe slot could be better used for? Thanks. ~n

• Windows 7 resizes desktop when I switch of a monitor

  - by Stijn Sanders

  I have a workstation with two monitors and the desktop extended over them. I have a lot of applications open (generally maximized), and I have a personal preference which application is on which monitor (let's say editors on the right, data retrieval and display on the left). I have recently upgraded to a workstation with Windows 7 and when I power off a monitor (typically when going home at the end of the day), the desktop-expand-over-monitors disables and all applications are switched to the main monitor. (Also the taskbar I keep on the left resizes to about one icon's width.) This is highly annoying, since I now spend the first minutes of work each day switching the applications back that were on the monitor on the right. Is there a way to prevent this? (It says no here.) Is there software I could install that can prevent this?

  When I hit the sleep button in Windows the computer looks like it's going into Sleep mode but a few seconds later it's restarted, and stops with this error message: internal hard disk drive not found To resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 for setup utility Press F5 to run onboard diagnostics. The computer is running Windows Vista (SP2) and I have installed all available Windows Updates and the latest manufacturer drivers. I have already tried to reseated the drive, ran the onboard diagnostics and there were no errors. I have changed the power settings for all devices where it's available so that they are not allowed to wake up the computer. Any ideas?

• Virtual Machine Performance - More RAM or More Processor?

  - by webworm

  When looking to improve Virtual Machine performance what would be better ... Increasing the available RAM or increasing the processor power? Here is my choice ... Core 2 Duo @ 2.4 GHz with 8 GB RAM and integrated graphics (Mac Book Pro 13") Core i7 @ 2.6 GHz with 4 GB RAM and 512 MB dedicated graphics (Mac Book Pro 15") I plan to run Windows x64 in the VM with SQL Server 2008, Visual Studio 2010, and SharePoint 2010. I am planning to run VMWare Fusion v3. I also didn't know if a dedicated graphics card makes a difference when using a Virtual Machine. Thank you.
