• Suggestion of device WiFi range in it's spec. Possible?

  - by SeeR

  I have router Draytek Vigor 2100VG at home almost in the center of it. The farthest point at my home is my balcony, ~12m from it. I have constant wifi signal range problems with some of my devices, but not with others. Notebook Lenovo W510 - no problems Nokia Home Music - always on 10m - no problems Sony PS3 - always on 7m - no problems Sony tablet S - problems around 6m Sony PSP - problems around 8m Sony PS Vita - problems around 8m Nokia E63 - problems around 8m I'm curious why my Notebook don't have any problems even on the balcony? I guess it has better hardware or uses more power for transmission. This information is really important when you want to buy new device/computer, so my real question is: Can device wifi range can somehow be found/suggested from official hardware technical specification? If not Is there some web page with wifi range reviews?

• Windows 7 random black screen when idle

  - by Omar

  Occasionally, when I'm away from my computer for about 5 minutes, the computer screen will go black and all USB devices (keyboard/mouse) will lose power. Attempting to move the mouse or pressing keys does not 'wake up' the computer. This only started happening a few days ago but I'm not sure what changes I did could have caused this and I uninstalled programs (one by one) I installed before it started happening, but still having the same issue. The one thing I noticed different about my computer since it started happening is i've been getting random survey popups from www.insightexpress.com. I ran Microsoft Security Essentials scan, it picked up some Java related malware, I removed it but still the same issue. I'm running MBAM right now and will run SAS after. Edit: I just updated drivers for motherboard and video card and ran virus scans, still having the same issue.

• Keyboard glitches for some when Ctrl key is pressed

  - by user270716

  I'm having some problems with my keyboard, if I press the Ctrl key it glitches for some time. For example, if I press Ctrl and press Tab while it's still glitched the computer shuts down as if i pressed the Power On/Off button. If I press a it "presses" Alt, A and a symbol I can't remember, if I recall correctly it's a currency symbol. If I press Ctrl again it "presses" the ' key. I'm using Windows 8 Single Language 64 bits with a ABNT2 keyboard. The processor is a Intel Celeron G530 with 2 GB of RAM.

• Mac OS X Server 10.6.6 "disables" CPU in VMware Fusion

  - by wjlafrance

  I installed Mac OS X Server 10.6.0 in VMWare Fusion the other night and it worked perfectly, until I ran Software Update. I upgraded to 10.6.6 through the combo updater, and now when I start the VM it says: "The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point." I've switched the operating system in the options to OS X Server 32bit, 64bit, and even to Windows 7, and nothing has worked. Does anyone have any ideas?

• Mint 13 does nothing when laptop lid is closed

  - by ewok

  I have a laptop running Mint 13. I have it hooked up to a 30" monitor and have no use for the laptop being open, so I put it on a shelf and close it. When I do that, the monitor goes blank. The power manager does not have an option for doing nothing when the lid is closed. The options are "Blank Screen", "Suspend", and "Shutdown". Is there a way to make the laptop not go to a blank screen when the lid is closed?

• Windows 7 x64 Hard Freezing (again)

  - by Lanissum

  Awhile ago, my computer was randomly freezing a few minutes after booting, and I ended up replacing the CPU and mobo after testing the RAM and hard drive, I also couldn't find anything wrong with the video card. So after replacing the presumably faulty hardware, everything worked fine for about a month and a half. All of a sudden, My computer is randomly freezing a few minutes after loading up any intensive application (games, mostly). Most of the time it just freezes with the current frame until I hard reset, although once it printed a BSOD message stating that dxgmms1.sys was to blame. The only difference between these two episodes I can think of is that I can do word/internet/work without issue now, as opposed to the near uselessness my computer was rendered last time. For those of you who want to know, I tested my memory with memtest86 (for 64 bit machines). I can't figure out what could have started this latest round of issues, the event logger just states that a kernel-power event has occurred (like last time) but I think thats just a generic "this machine has rebooted after a sudden shutdown" message.

• Keyboard doesn't work after Windows resume from sleep (S3) -- how to fix?

  - by Marco Z

  I have a weird issue with my keyboard after resuming from S3 sleep: I can type perfectly for maybe 5 seconds, but afterwards the keyboard ceases to work until I hibernate or restart (or sleep again -- see below.) The rest of my system runs just fine -- just the keyboard apparently "freezes" up. Some closer observations: The keyboard will work for 5 seconds (and freeze again) every time I resume from sleep, even if it was frozen from a previous sleep The caps lock light will work fine within the 5 seconds. But after the keyboard "freezes", the light will remain on, but I'll be unable to turn it off. Perhaps this means power wasn't cut off from the keyboard, but it's just some software freezing up the port??? Given this info, would this indicate a problem with Windows itself? Drivers, maybe? Can I rule out the BIOS as the culprit? Finally, any ideas on how to fix? Thanks! Specs: Windows 7 x64 HP tx1000 laptop

• Open source report framework

  - by Tiax

  I'm looking for a open source report framework for statistics. A more detailed explanation is: We have a number of tests running on different servers collecting data (for example, login time) every 5min. What we need is a framework that collects this data (or exposes web services for us to push the data into the framework) and presents it in form of graphs and so on. Does anyone know of a framework that's easy to use out of the box but has the power to grow? If you know what I mean. Thanks in advance!

• Windows: Should I install Server or stick with regular?

  - by stalker92

  I hope somebody can help me solve my dilemma. I have my home PC (using Windows 7) which I use for both work and leisure (gaming, surfing, movies etc.) I tend to never turn it off, only when I must reboot because some installation requires me to or when the power gets lost. But, sometimes Windows starts acting weird (usually after the long period of system uptime), per example eats up randomly all the space on my system partition etc. which is solved after the reset by itself. I was thinking to switch to Windows Server, I guess that it is more optimized for long uptime, well, obviously it is meant for use on servers. Can somebody with more experience with this help me decide is it worth it, will it solve these issues connected with long uptime periods? Thanks in advance.

• Decent 1gb switch (16-24 port) for rack...

  - by TomTom

  Hallo, for a rack containing a smaller nubmer of servers (5 at the moment, going to stay in this area), I look to replace the currently aging 100mbit switch with a 1gb switch. This is for the backend between the servers. I expect some ISCIS traffic there ,so a 10gbit option would be nice (preferably for two ports, as extension modules). I dont need management, this is a pure backend of an internal cluster. I do VLAN, but there is no sensible management the switch can do there. I wuold like: * 1he only, obviously * preferable limited moving parts. * Low price ;) * Enough power to run at least half the ports in full speed at the same time. Anyone any recommendations?

• PC powers up but there is no display

  - by Matthew

  I built a computer with standard components I bought from Newegg about three years ago. It ran great for 2 years and has sat powered down for the last year. I tried to power it up today and the display was blank. It powers up, lights come on, drives start spinning but there is nothing on the display. I verified that the monitor and video adapter work. I also tried the video adapter in a different slot on the mother board with no luck. What's the next thing I should try? Is the mother board shot? Thanks.

• Issue with broken disk on Solaris with raidctl - how to proceed

  - by weismat

  I have a SunFire T2000 server which has 2 mirrored disks pairs. The server required an exchange of the system battery. After swaping the battery first no disks were found. After booting from CD we managed to find the disks, but now one disk is broken and the raidctl reports a failed synchronisation. The boot process stops now when trying to mount the file systems. The power light of the broken drive is not even blinking. What is the best way to proceed now ? Fortunately I could live with loosing the data on the drive as it is backed up, but I would like to keep the rest of the data as it contains /etc and get the server booting again.

• video card for only watching videos

  - by Nothing 2 Lose

  I recently quit gaming so I took out my (GeForce GTX 550 Ti) video card and switched back to the (cheap) integrated card because I don't want the dedicated card using up power & making unnecessary heat/noise. But now I get lag when I watch high-res movies, or when I open several videos at the same time, but I don't want to go back to my (big/expensive) video card because that seems like overkill. What is the smallest/cheapest card which will only be good enough for watching videos without lagging ? (but not for gaming) PS. My CPU is: AMD Phenom 9850 Quad-Core Processor

• Blackberry Won't Sync: Says Processing

  - by Noah

  I have a blackberry storm 2 and I have it set up to sync, just like I've done with all the other ones in the company. They pull the address book/contacts from outlook, and aren't synced to an exchange server. I have everything setup and then when I hit synchronize it flashes "processing" the phone shows it trying to sync and then it is done in less than a second. It did warn me that the computer was not supplying enough power to charge the device and it said that I should make sure the drivers are correct. Also, I was warned that the device might not function properly down in the bottom right hand corner. Any ideas? I've uninstalled and reinstalled the blackberry software off the disc.

• Lynksys WRT120N wireless router not connecting to ADSL

  - by pradeetp

  I have a lynksys WRT120N wireless router that was connected to Sterlite ADSL modem. The internet connection was working fine through wireless access. I changed the ADSL router because it developed some power issues and got it replaced with the same model/brand from the service provider. However I am not able to access internet now. Here is the current setting Sterlite SAM300 XA IP Address: 192.168.2.1 (I changed it to this IP because the IP address of my ADSL router was same) Lynksys WRT120N wireless router IP Address: 192.168.1.1 If I connect my laptop to ADSL router directly, the internet works fine. It is only that that if I access it wirelessley through wireless router that I am not able to connect to internet. The IP address setting has been configured to obtain IP address automatically. I have windows 7 OS home edition. Could someone please help me to fix this issue.

• If an old Exchange server is not part of a domain, does that imply that it can be safely removed without affecting mailflow?

  - by Bigbio2002

  We are doing some cleanup, and there is an old Exchange VM hanging around that we want to get rid of. We do not have the local admin credentials, but we can ascertain that it is not part of the current domain. Seeing as the new production Exchange server is working fine, is it safe to power off and remove the old server? *I should probably note that this is not an Edge Transport server. There was an upgrade to Exchange 2013 at some point in the past, and there is only one functioning Exchange server now.

• Where can I find more information on "Kinds of Information Systems" [on hold]

  - by arielnmz

  Disclaimer: This is not a Power User question, but rather more of the Computer Enthusiasts kind. Also, I don't know the right site to post this kind of question. I'm writing a paper in which I am asked to mention and describe "5 types of information systems" to which my teacher explained: Like Web, Mobile, etc…, for example… He also said that we're not able to mention and describe those mentioned above. So the question is: What is the right topic to research or look into for more information about these different types of "information systems"?

• Samsung TV connected to PC for Powerpoint

  - by Skaughty

  I have a 42" Samsung LCD TV connected to a Dell computer with a PCI Radion 9000 via a 35' VGA cable. It's purpose is to run power point presentations over the TV for our retail store. I have tried every combination of button clicking on the video card options, and everything on the TV, and I still get black bars on the top and bottom of the image. It looks like I am watching a old wide screen movie on a full screen TV. The TV's suggested resolution is 1024x768, and that is what the output is set to. I have tried this with a nVida PCI card as well with the same results.

• Laptop with Windows 7 turns on spontaneously while being in "Sleep" state

  - by alexb

  I own a laptop(HP Pavilion DV7) with Windows 7 installed for already half a year. Usually when I finish my work I do not turn machine off - closing is enough to get is into "Sleep" state. Generally it's okay for me, but recent several days laptop was turning on in night spontaneously, while I was sleeping. I haven't installed any app with "turn-on by schedule on when_dooes_pc_wants"-like features. Checked if there are some "Wake-On-Lan"-like settings in BIOS, haven't found ones. The power-cable is always plugged-in. Does someone have any suggestions regarding that? p.s. laptop is placed right near by bed, so when it turns-on on night - it is quite annoying and a bit scary. I think it's trolling me, please help to stop it :) Thanks.

• Open original Microsoft Office document (not "version 1") on Mac OS X Lion restart

  - by FlyingMolga

  My MacBook Pro running Lion has been frequently freezing lately, and I've had to restart with the power button. When Lion starts up again, the Microsoft Office applications that were running start and load different autosaved versions of the documents I had open (i.e. it does not open abc.xlsx but [version 1] of abc.xlsx). Sometimes it also opens the original files. Several times I've inputted data into these "version 1" files, only to try to save it and realize that it isn't the original file and is sometimes missing data that is contained in the original file. Is there any way to make autorecover open the actual document with the unsaved changes, instead of making a new temporary version?

• Windows 8 taking 4+ mins to shutdown

  - by arnab321

  I did a fresh installation of Windows 8 64 bit, build 9200 (released on aug 16th). I installed the drivers and some basic softwares like NetBeans, mingw, iis server and php. For the first few times, it was restarting normally. But then at shutdown, it would show the shutdown screen for some seconds and then turn black for about 4 mins (similar to what happens at hibernation). I disabled the "fast startup" option in power options, but the problem still persists. Windows 7 and Ubuntu shut down normally. specs: 4gb ram, 750 gb sata hdd, solved by installing Windows Updates released during October. It was a serious bug in the OS, afaik. Now even hibernate takes upto 30 secs max. Still, win 8 is too buggy for release.

• EXT4 external hard drive for use with multiple systems

  - by EXTdumb

  I recently bought a external hard drive to store some data on. I use Linux but I am not a power user. If I format the drive to EXT4, is it possible for the permissions to ever screw up and I lost access to my data? I will be plugging the drive into several different linux based computers at work and I frequently hop distros on my main home machine. I need to make sure I don't lose any data because I overlooked something. I am not familiar with EXT 3 or 4. So far I have done this : Formatted drive to EXT4 ran gksudo thunar and changed the permissions to my user account and all settings to read/write Wrote all the files I need to the drive I really appreciate any help.

• Screenflick Audio option in MacBook Pro

  - by John

  When after I shut down my MacBook Pro by holding the power button for a few sec, (which I found is bad for the computer, so I will not do anymore) I found that my speaker doesn't play until I plug in and out earphone into the machine. When my speaker is not working like this, and when I am on a random webcam chatting site like chatroulette.com, they can hear the music playing on my iTunes when I choose Screenflick Audio option in the Mic setting. But when the Speaker is working back again, they don't hear the music playing even when I do Screenflick Audio mode. How can I make it work? Also, how do you make the chatting partner hear my music playing on my computer while I talk to them (not via my speaker, since it's bad quality).

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. The laptop has a Intel 4500 video card. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• Xen VGA passthrough: is it possible to have dual GPU's with single monitor

  - by user489481

  I hate dual-booting between Windows when I want to play a game and Linux when I need to work. I don't fancy running Linux in a VM and Wine almost never works for me. So, I'm thinking about buying a new mainboard and CPU that is compatible with Xen's VGA passthrough and HVM virtualization. I want to be able to switch between the Linux Dom0 and Windows DomU with ease, but the problem is I need two GPU's and have only one monitor. Right now I have a nVidia GTX 260 in my PC, but I also have a Radeon 4850 sitting in my closet that I was going to sell. My question is, can I salvage the Radeon card to run the Dom0 and have the nVidia card run the DomU while having some kind of device/software to connect them a single monitor? Power supply and airflow issues aside. If not, what would you suggest? Is this even possible?
