• Why would a machine ruin three "power supply"s?

  - by Moshe

  A client of mine has an XP era eMachines. The power supply has died and been replaced 3 times. I've discharged the motherboard and checked the surge protector. In the middle of a scan with ComboFix, the machine died. It powers on and hangs before the BIOS and shows a solid yellow light. I believe the model # is T5062 or something like that. Aside from a bad outlet, what would cause the PSU to die a few times?

• Windows XP does not list WPA wireless networks

  - by Tomalak

  What can be the reason that Windows XP does not show WPA-encrypted wireless networks? The laptop I have problems with is an older model (Toshiba Satellite Pro 6100) with Windows XP SP3 on it, fresh install. The wireless network card in it is an Agere product that lists as "Toshiba Wireless LAN Mini PCI Card". The networks showed up perfectly before I first tried to connect to one (it was set to WPA2). The connection failed (the card supports WPA only), then something must have happend and Windows hides these networks now. A manually configured WPA setup via Windows' own wizard works, I'm using it right now. The network just won't show up in the list of available network on its own. I suspect that XP incorrectly set a flag somewhere that this network card does not support WPA. Is there such a flag, and if so, how can I change it back?

• Properly configuring Linux keyboard on my laptop

  - by antoniocs

  Hey! I have a ps/2 keyboard connected to an Acer Aspire 1694 WLMI via a ps/2 to usb converter. The laptop is running Ubuntu 9.04. The keyboard is a HP model number: SK-250C. I have configured in the 'Keyboard Preferences' the layout to HP SK-250x Multimedia Keyboard. The big problem is when I press certain keys (like for example the arrow keys) I get the 'Save Screenshot' dialog. This is really getting annoying, sometimes I am tying to write an address in browser and just want to go back a few letters and can't. There are other keys that trigger the dialog also (windows key, insert key, home key, page up and page down key, delete key, end key) All works fine If I use the laptop keyboard, but I really want to use the HP keyboard. EDIT: I was testing this and it seems that if I have the 'Num Lock' key turned off the keys work properly. Strange but true!!

• Time values not saving in Airport Base Station MAC Timed Access List

  - by Boiler Bill

  I have an airport base station model A1354. I am attempting to setup MAC Timed Access so a laptop can only connect between 5:00AM and 11:00pm through the Airport Utility version 5.5.2 (552.11). My AEBS is running firmware version 7.5.2 When I try to enter the time values by double clicking over the time and entering 05:00 AM and 11:00PM the time values don't stay as soon as it looses focus. Instead they become what is in the following screenshot, and the laptop looses connectivity as soon as I update the base station. I also tried entering the values in military time with the same result. Any base station power users out there that know how I can get the time values to "stick"?

• Need help. HDD Failed

  - by jiewmeng

  i have a seagate 3.5" 500GB SATA2 HDD that i put in a USB case (vantec) that failed recently. symptoms: at first, it started except that attempts made to browse certain folders resulted in "Data Error (Cyclic Redundancy Check)". then when i tried restarting the hdd, then i got a RAW partition, and windows 7 said i need to format it. i also tried using a desktop to connect to the HDD directly using SATA, windows 7 stuck at "starting windows" for abt half hour b4 i gave up on it. in the BIOS, it seems to detect the HDD model correctly, something like STA3500xxx something like that i also tried using TestDisk as suggested by jaclaz on MSFN and it did not find any partitions what could i do now?

• Is a larger hard drive with the same cache, rpm, and bus type faster?

  - by Joel Coehoorn

  I recently heard that, all else being equal, larger hard are faster than smaller. It has to do with more bits passing under the read head as the drive spins - since a large drive packs the bits more tightly, the same amount of spin/time presents more data to the read head. I had not heard this before, and was inclined to believe the the read heads expected bits at a specific rate and would instead stagger data, so that the two drives would be the same speed. I now find myself looking at purchasing one of two computer models for the school where I work. One model has an 80GB drive, the other a 400GB (for ~$13 more). The size of the drive is immaterial, since users will keep their files on a file server where they can be backed up. But if the 400GB drive will really deliver a performance boost to the hard drive, the extra money is probably worth it. Thoughts?

• external HDD with SATA & USB interface?

  - by Greg

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model. Preferably one of the name brands so I have a better change of finding it here or locally if possible. Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

• Why does iChat Server keep connecting to proxy.eu.jabber.org?

  - by Tom Hamming

  I have OS X Server 10.6.5 running on a new Mac Mini (server model), serving several functions among which is iChat Server (iChat and Pidgin on Windows as clients). In the iChat log in Server Admin, I kept seeing entries about connecting to proxy.eu.jabber.org. It's for our office network and I wasn't excited about external access to it, so I disabled server-to-server XMPP federation and now the connections just time out. But why is it doing that in the first place? Sample log entry: (datetime) (servername)jabberd/resolver[portnum]: [xmpp-server._tcp.proxy.eu.jabber.org resolved to 208.68.163.220:5269 (300 seconds to live) then: sending dialback auth request for route '(full server hostname)/proxy.eu.jabber.org' A couple minutes later, it comes back with: dialback for outgoing route '(full server hostname)/proxy.eu.jabber.org' timed out

• Using a 3g usb dongle as Cisco router access point

  - by beakersoft

  We have an office opening, and we aren't going to have comms into the building when management want the building to open. Our only option (I think) Is to try and hook up a 3/4g dongle to something to act as the access point, and send all the traffic via that. The model of router we use wont support the usb dongle, so we need some sort of 'bridge' My idea was to build a Linux box, plug the dongle into that and then via the Ethernet ports plug the router in. We need the Cisco router in the equation as we create VPN connections over that back to head office. My question is will this work?

• Safe BIOS upgrade run from external USB-HDD and not native OS

  - by ecoologic

  I have a Toshiba M200 laptop which came with Windows Vista. After buying it, I replaced the OS with XP and recently I swapped the internal hard disk with a bigger one where I only have Ubuntu. So now I can boot XP from the external USB hard disk. There's a BIOS update available (2.3 against my 1.8) which I'd like to install and there's also a version for XP. Is it "reasonably" safe to install this upgrade for Windows XP (despite the original OS was Vista, the laptop model is the right one) from my external USB hard disk with Win XP?

• Troubleshoot odd large transaction log backups...

  - by Tim

  I have a SQL Server 2005 SP2 system with a single database that is 42gigs in size. It is a modestly active database that sees on average 25 transactions per second. The database is configured in Full recovery model and we perform transaction log backups every hour. However it seems to be pretty random at some point during the day the log backup will go from it's average size of 15megs all the way up to 40gigs. There are only 4 jobs that are scheduled to run on the SQL server and they are all typical backup jobs which occur on a daily/weekly basis. I'm not entirely sure of what client activity takes place as the application servers are maintained by a different department. Is there any good way to track down the cause of these log file growths and pinpoint them to a particular application, or client? Thanks in advance.

• Very fast Laptop Heating due to very high CPU usage by dwm.exe

  - by Sushan Shrestha

  My laptop gets heated very fast and when I check the task manager, I find dwm.exe consuming very high CPU (mostly 100%). In the beginning I found the message "The graphic adapter has been stopped and recovered".Also I am getting one error message "Cidaemon.exe has stopped working" very frequently. During this period also, cpu usage is 100% which is consumed by dwm.exe. I have run ccleaner and Kingsoft PC doctor monitor to fix the register problem but the problem has not been solved. My display adaptor is : NVIDIA NVS 5200M. After the driver update, I am not getting "The graphic adapter has been stopped and recovered" but dwm.exe is still consuming 100% CPU one time in about 5 mins. Multiple restarts has not helped. Laptop Model: Dell Latitude E6430. Thanks in advance.

• Computer not working, motherboard is suspect

  - by Arlen Beiler

  I have a problem with my computer. I have a GeForce 6100 M9 Motherboard, which I suspect is broke. The capacitors beside the CPU are corroded and the computer doesn't do anything except start the fans when I push the power button. The problem is that I can't find another motherboard as they apparently don't sell this model anymore. I have tested the Power Supply and it appears to be working. Any advice would be appreciated. Different forums have mentioned that you can replace the capacitors. Any help on this would be appreciated.

• Setting up 2 external monitors on a laptop with VGA splitter

  - by mike

  I have a laptop with a graphics card that supports 2 displays. I would like to know the easiest way to set it up so I can close my laptop lid and use 2 external monitors (unique displays). I use it primarily for office applications and video and want a quality, clear picture. The laptop has 1 VGA port and I have 2 24" 1920x1200 monitors that have VGA and DVI ports. So a few questions: Can I just use a VGA splitter? (seen mixed feedback on this) Would it a VGA to 2 DVI splitter give a better picture quality? (if it exists) Would I be better upgrading laptop to one with 2 digital ports ( I just see a lot with VGA and HDMI though) specs: Model: Toshiba Satellite C675-S106 (Windows 7) Graphics Card: Intel HD Graphics 3000 (supports 2 displays) Processor: Intel Core i3-2350M

• What is the fastest CPU my laptop can support?

  - by Dave

  I have a Dell Latitude D830 laptop and would like to speed up compile times on it. I have confirmed that it is, indeed, the processor time that is the bottleneck. How can I tell what processors are compatible with the motherboard to pick the best available? I run dual boot Ubuntu Maverick and Windows 7. lshw tells me that my motherboard is OHN338 from Dell, Inc. If anyone has a generic solution, i.e. "For motherboard X, here is how you find out what processors are supported," that would be make this question much more useful to future visitors. But if you also know of a way to find out specific to my model, that would be great as well.

• H.264 Pricing confusion

  - by Jamie Taylor

  not sure if this is the right place but there seems to be other H.264 questions here, if not please point me to the right place! I am taking uploaded content and encoding it to H.264, I'm confused about the pricing though. Do I have to pay to host and stream this video on my server (in Ireland). I've tried looking around google but there doesn't seem to be a definitive answer. Some countries have exceptions, some pay $2500. What kind of information should I be looking at to understand the pricing model more? Thanks.

• new pc..noisy fan

  - by BRQ

  It's a new build, but it's always had noisy fans. From start to end, they will not stop running. The case is a cooler master which I believe comes with a fan that is not controlled by BIOS (according to technician), so that may be the source of the problem..but my lack of knowledge on the matter prevents me from making a reasonable assessment. Here are readings from CoreTemp: Model: Intel Core i7 870 (Lynnfield) Platform: LAG 1156 (Socket H) Frequency: 1658.23MHz (132.66 x 12.5) Tj. Max: 99 C Core #0: low= 34 C; high= 42 C; Load= 0% Core #1: low 31 C; high 42 C; load= 0% Core #3: 35 C; 42 C; 0% Any input will be appreciated.

• Computer never connects to the internet automatically on startup?

  - by RawR Crew

  I have my Windows Vista laptop connected directly to the router via an ethernet cable, and every time I switch the computer on, the computer cannot connect to the internet. It comes up as limited or no connectivity, I am assuming because it has not been assigned an IP address by the router - not too sure if this is right. The problem is usually fixed either by performing a repair through the networking control panel or removing and re-inserting the ethernet cable. It will also connect without doing any of these if the computer is left idle for about 20 minutes. It will connect fine wirelessly without the need for any of this, however I would prefer to connect via the cable. Any ideas how I can fix this? I have replaced the ethernet cable and router already (identical model) but these haven't helped. Thanks for any help on this.

• install bluetooth in samsung R430, windows 7

  - by voodoomsr

  how can i install the bluetooth driver in this laptop in windows 7. The installation process tells me that i need to activate the bluetooth device to continue, but how can i activate if till that moment the device doesn't exist. There isn't any button or switch to activate the device manually. Edited: it's the np-r430 model. I read somewhere (a users forum, not official info) that for Chile and Argentina this models doesn't have built in the bluetooth device, but the US models have it. Maybe for some political and weird reason they send to south american laptops without that. The link of my notebook's specifications in an AR domain: np-r40

• Wrong screen resolution with HDMI output to HDTV

  - by bruno077

  I own an HDTV with a native resolution of 1360x768. Sometimes I plug in my laptop to watch movies, and I used to do it with a VGA cable. I've had no problem setting the laptop to the TV native resolution with the VGA cable (1360x768). Having acquired an HDMI cable recently, I can't go past 1280x720, and if I do, the TV displays "invalid format". At 1280x720, the image is viewable but not centered, so for example I can't see the windows taskbar or titlebars. I've tried both cables (VGA and HDMI) with the same settings: Laptop's display turned off and trying to set the Tv's native resolution. What could I try to fix this issue? Could it be a faulty cable? (I'm using a Thinkpad with Windows 7) EDIT: My graphics adapter appears listed as Mobile Intel(R) 4 Series Express Chipset Family (Searching for my laptop's model yields Intel GMA 4500MHD as the graphic card) I'm downloading a driver update from Intel's website. I'll report my progress when I check its behavior tomorrow.
