• Logging in to a locked computer

  - by Cpt. Jack

  Just recently I have stumbled across an old family laptop that has been out of use for nearly two years. The OS is Windows Vista Home Premium so I'm not quite as enthused about my find as I originally thought I was going to be. However, when I power up the computer it immediately bring me to a login prompt. No one in the family remembers the password it is set to and I am eager to get into this machine. Does anyone know of a way to work around this issue and get into the computer to be able to find out what was configured and saved on it two years ago. Without re-installing the OS I want to bring it back into commission within the family.

• How do I make webmin secure?

  - by Josiah

  I want to install webmin to make server administration tasks on my Ubuntu 10.4 server easier. However I'm very nervious about having that kind of power accessable over the web. So I want to know how to secure webmin so that it can't be used to comprimise my server. So far here are my ideas, but I still don't feel comfortable: Make webmin accessable from only the localhost (how?) Use SSH tunneling to access the webmin server whenever I need to administrate it Can anyone help me with instructions on making webmin accessable only from the localhost? What other ways can I make webmin secure?

• Asus z53 laptop overheating problem

  - by Tiberiu Hajas

  hi all, wondering if anyone encountered overheating of asus laptop ? especially the z53 model ? usually the right side of the laptop and vent in the upper corner is blowing hot air when under even minimal load, the CPU temperature can easily get to 65-70C and GPU is even above 80C. I'm using NHC (notebook health control) to set to a higher conservatory power consumption but that helps only a bit, anyone opened up the case ? wondering is require a dust clean ...etc ? I still have some warranty on it. thanks

• Click sound from computer when shut down

  - by user32569

  Hi, I build my new computer yesterday and I noticed, when computer is shut down, I mean the exact time its looses power from PSU, relativelly loud CLICK sound occurs. Please does anyone knows from where? I think MB, SSD, VGA, CPU nor coolers are not cousing this. I would guess maybe Samsung 1TB HDD (maybe when heads go back to LZ) or some hard safety switch or relay in PSU? Or just the MB speaker? (Yes, its actually installed). Do you have any experience with this? Thanks.

• What is the method to reset the Planar 1910m monitor?

  - by Richard J Foster

  My monitor (a Planar, apparently model number PL1910M) is not working. (It is flashing a green / orange sequence which I believe to be an error code. The sequence, in case it helps consists of orange and green three times quickly followed by a longer orange, then another green followed by a long period where both colors appear to be present). I vaguely recall a co-worker suffering from a similar problem, and our IT department "resetting" the monitor by holding down a certain set of keys as they apply power. Unfortunately, I do not remember what that key sequence was, our IT department is not responding, and the Planar web site is blocked by the content filtering firewall we have in place! What is the sequence to perform the reset? (For bonus geek-credit, what does the code mean... as if it indicates a blown component clearly a reset will not help me. ;-))

• Windows 7 setup can not find hard disk

  - by Akshay Kulkarni

  Previously I had an old Seagate barracuda 160GB HDD which got crashed some days before. Yesterday I bought new Hard Disk Seagate Barracuda 500GB (ST500DM002). I just replaced the 500GB hard disk with 160GB one leaving data and power cable intact and untouched. And ideally this new hard disk should start functioning. I tried to install Windows 7 with DVD the setup says you don't have any hard disks installed on your machine. I rechecked connection tried with Win XP setup but continued receiving same error. Do I need to do some initialization stuff with hard disk before installing setup? If so how to do it. If not then is there any problem with my newly bought hard disk? Thanks In Advance.

• SATA hard disk for laptop on Desktop PC

  - by Lawliet

  I know that this forum is for programming-related questions only, but I'm having this dilemma so here I go. Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) Thanks in advance

• Laptop VGA Out Stopped Working

  - by Jack7890

  I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

• Mac keeps switching to second graphics card

  - by 1.21 gigawatts

  I have a MacBook Pro and whenever I enter certain apps (video camera app or Photoshop for example, the graphics card switched. I didn't know this was going on at first; just that the screen kept changing colors as I opened or closed different software. Later someone told me that the software was causing the OSX to switch graphics cards. It's annoying. How do I keep one graphics card (the better one) enabled all the time? I don't care about power consumption because it is plugged in all the time (though I'm curious how much difference it makes). I just want one graphics card enabled.

• Computer froze up

  - by Arlen Beiler

  Why would my computer freeze up out of the blue? I have Apache Webserver w/php, and MySQL server installed. I am not sure exactly when it happened, but I was doing something on a wordpress site that I have installed, and it just waited and waited and waited. Then, all the folders on it that were open on my other computer closed, as though I had disconnected it. Then the skype account went offline. The computer was totally froze. I thought maybe it was someone on logmein, but disconnecting it from the network didn't do anything. I had to "crash" it (held in the power button till it shutdown). It started up normally then and the logs showed absolutely nothing wrong. And doing the same thing that I did when it froze didn't repeat the freeze. Any ideas, I never had this happen before.

• Hypertransport sync flood error

  - by Carl B

  What is it? And what causes it? Is it only for uncorrectable DIMM Errors(Troubleshooting DIMM errors)? When an UCE occurs, the memory controller causes an immediate reboot of the system. During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage: A Hypertransport Sync Flood occurred on last boot 3 BIOS reports this event in the service processor’s system event log (SEL) as shown in the sample IPMItool output There are what seems to be some suggested answers to include Bad Caps Bios verisons (happens in one version not the other) Graphics card issues Lack of power to the CPU The list of possible generators seems to target everything but the computer case.

• Suggestions for Troubleshooting WIndows 7 lockups

  - by Craig L

  I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

• What is the Best Free Linux Gateway

  - by rockinthesixstring

  I'm looking at moving away from using my DIR-825 as a gateway and moving into a Linux box to do it all for me. I've found IPCop, but I'm looking for something with a little more power. My main goal is basically to be able to point different external domain names to different internal servers. backup.example.com - 192.168.0.5 home.example.com - 192.168.0.1 I host my DNS on my own dedicated server (windows), so I don't know much about doing the gateway thing in my home (my hosting provider does it all for me). Do any of you know of any free Linux Distros that can accomplish what I'm looking for?

• Scripts under pm/sleep.d are not getting called when suspending with KDE 4.3

  - by Richard Corden

  Fujitsu-Siemens H240, Slackware-current, KDE 4.3.2. I would like to perform some additional steps when my laptop suspends. I found this SU question which is very close to what I am asking, however the scripts that I placed in that directory are not being called for me. This could be a Slackware thing, or its possible that KDE has a different location for these scripts. I am suspending by using the "Suspend" radio button on the "Guidance Power Manager" dialog of KDE. Is there a standard location where I can place my scripts so they'll be run before and then after the machine has suspended?

• Finding underlying cause of Window 7 Account corruption.

  - by Carl Jokl

  I have been having trouble with my Sister's computer which I built. It is running Windows 7 Ultimate x64. The problem is that I have had problems with the accounts becoming corrupted. First problems manifest themselves in the form of Windows saying the profile failed to be loaded properly and a temporary profile. Eventually the account will not allow login at all. An error message along the lines the authentication service failing the login. I have found information about this problem and how to fix it. The problem being that something has corrupted the account profile and backing up and recreating the accounts fixes the problem. I have been able to fix things and get logins working again but over the period of usually about a week it happens again. Bit by bit the accounts corrupt and then it is back to square one. I am frustrated because I don't know what the underlying cause of the problem is i.e. what is causing the accounts to be corrupted in the first place. At the moment I am just treating the symptoms. I was hoping someone who may have more experience with dealing with this problem might be able to help me find the root cause. Some articles suggest that Norton Internet Security is a big culprit of this problem which is installed. I could try uninstalling Norton and see if it helps. The one thing which is different about this computer to any other I have built is that it has a solid state drive. Actually it has both a hard drive and solid state drive. The documents and settings i.e. the Users directory is stored on the hard drive. This was done following an article about moving the user account data onto a separate drive on Windows 7 which I found on the Internet. Moving the User accounts is more of a pain under Windows 7 and this solution involved creating a low level file system link to the folder from the boot drive (Solid State) to the Hard Drive. The idea is that the computer behaves just as if it is accessing the User's folder from the boot drive but actually the data is stored on the hard drive. This may have nothing to do with the cause of the problem but due to the problem being user account corruption it is a possibility I have not been able to rule out. Any help would be appreciated as I would be glad to see the back of this problem.

• Repair snapped USB flash drive

  - by Richard Slater

  I have a USB Flash Drive that has had the USB connector snapped away from the circuit board. In the past I have had great sucess with soldering the connector back to the circuit board with 4 solid core wires. Unfortunatly this particular device shows up as "Unknown Device" in device manager and displays 0ma power usage. Giving a closer look at the circuit board it appears that the Data + connector has come away from the PCB. Which would explain why it is not recognised. Is there any practicable way of lifting the data from the device? larger version

• Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

  - by pkaeding

  I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter-USB adapter, or a wall power-USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer. However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge. Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?

• Multiple servers acting like a single one with all the hardware?

  - by marc.riera

  Hello, by now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch. Any advice on wich software to use will be very useful? Thanks

• windows vms unpredictibly require login

  - by marrrkus

  I have a cluster of vms on a number of cloned servers using libvirt/qemu. Occassionally the windows 7 vms randomly require a login screen, even though I've done everything I can think of and can google to turn off a login screen. I've used netplwiz to turn off requiring a password (http://pcsupport.about.com/od/windows7/ht/auto-logon-windows-7.htm) manually changed the regsistry using the instructions here: http://superuser.com/a/28654 changed requiring a password in the power saving settings in the control panel if the screen goes to sleep told the screen to never go to sleep (in the control panel) Even with all of these things, some of the vms *still* randomly require a login. I have no idea what else to try. Any ideas??

• MacBook says to replace battery. Should I?

  - by Palantir

  Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P
