  • Viruses on external hard drive -- how to clean files?

    - by Jade
    Last year my Dell laptop caught some pretty nasty viruses; I saved all my important stuff on an external hard drive. In an unrelated turn of events, I replaced my Dell with a Mac and have been able to retrieve data from the hard drive without trouble. The problem is, I'm sure the hard drive has a few lingering viruses and I really don't want to infect any more PCs with it. I was planning to reformat it anyway, but I'd like to be able to save my files. Would transferring those files to my Mac and then scanning them for Windows viruses before throwing them back onto the newly reformatted hard drive be enough?

    I have a Dell Inspiron 15r se 7520. I have upgraded my system to Windows 8.1 few days back. After the upgrade, my Intel HD 4000 graphics driver stopped working. I have downloaded the latest driver from Dell website but during installation it said that my graphics driver is not compatible or validated and also my dedicated graphics driver AMD ATI Raedon HD 7730m also stopped working. There is also a problem with my screen brightness: I am unable to change it. How to make my graphics driver work?

  • Can I use dis-similar HW for Win2008r2 DFS-R

    - by cwheeler33
    The setup: Windows 2008R2 Ent on two machines. The roles on each server will include File Servers and DC's. The machines come from two different vendors (Dell/HP) The Dell is an Athlon and the HP is an Intel. Both have roughly the same speed CPU and 8GB of RAM. They have different Raid controllers, and more or less the same amount of disk space (roughly 6TB.) Can the servers use different types of hardware? Is there any documentation about this? The last question I have is about the network. Can DFS-R be forced to use a differen subnet from the regular network?

  • Network card dies when trying to wake up laptop from sleep

    - by Bugmaster
    I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?

  • upgrade to windows8

    - by Siddharth Warrier
    I have a dell inspiron N5010 laptop. I am planning to upgrade to windows 8 and the existing version is windows 7. So when I planned to upgrade I found that in the website of dell they have not updated the drivers for windows 8. I had installed a preview version of windows 8 and installed the drivers of windows 7 so it got installed and is working fine. So shall I upgrade it to windows 8 and use windows 7 drivers???? or wait till the drivers are updated??????

  • I can't set the resolution to that recommended by my monitor

    - by F4r-20
    Firstly, I have looked here but didn't find what I needed. I have a Dell Optiplex 380 only using the on-board graphics (believe its the Intel G41 Express Chipset) but I can't seem to get the resolution right. The monitor I'm using (HP LE1901w) wants me to use 1440x900 but the only options I get are: 1600 x 1200 1366 x 768 1360 x 768 1280 x 1024 1280 x 960 1152 x 864 1024 x 768 800 x 600 So it will allow me to go higher or lower but not 1440x900. I've tried getting the driver from various different sources (Dell, Intel, Windows 7 Update) but still can't get that option. Does anybody know what else I can try?

  • Teaming/Spanning Switch Ports

    - by KTech
    I like to team NICs on my servers. Since most workstations are giga-bit anymore I want to provide my servers a bit more bandwidth. I've read various things that say I am/am not supposed to bond the ports on the switch. I see benefit in doing it as I'm not sure how the switch ARP table handles the same MAC address on multiple ports. Suggestions on the "ideal" way to do it? If it matters, I have mix (various locations) of Dell and HP, web managed, Layer 2 switches. Servers are mostly Dell with Broadcom NICs.

  • External monitor turning black intermittently

    - by coding crow
    I have installed an external monitor (Dell ST2220L, 21.5 inch) on my laptop (Sony Vaio). I am using a DVI-D cable for connection. Since the laptop does not have a DVI-D port, I have connected a DVI-D to HDMI connector on the laptop end and inserted the cable in HDMI port of the laptop.. I have switched off the laptop display and adjusted the screen resolution on the Dell external monitor to 1920 x 1080 and adjusted colors for the Windows 7 and brightness and contrast from the monitor. The problem is the monitor turns of blank intermittently for 1-2 seconds and turns on again at random interval. What could be the reason for this and how to get rid of this problem?

  • Trying to build a history of popular laptop models

    - by John
    A requirement on a software project is it should run on typical business laptops up to X years old. However while given a specific model number I can normally find out when it was sold, I can't find data to do the reverse... for a given year I want to see what model numbers were released/discontinued. We're talking big-name, popular models like Dell Latitude/Precision/Vostro, Thinkpads, HP, etc. The data for any model is out there but getting a timeline is proving hard. Sites like Dell are (unsurprisingly) geared around current products, and even Wikipedia isn't proving very reliable. You'd think this data must have been collated by manufacturers or enthusiasts, surely?

  • Can I create an Infrastructure access point from built-in WiFi (as opposed to Ad-Hoc) on Windows XP?

    - by evilspoons
    I want to use my Windows XP laptop as an access point. What I am trying to achieve is possible under Windows 7 with a myriad of utilities, but the wireless driver stack was different before Windows 7 and those specific APIs don't exist on XP. The reason behind me wanting to do this is that I would like my Android phone to be able to connect via WiFi to a network that is only hard-wired (reverse tethering). Unfortunately, my Android device (Galaxy S Captivate) does not support ad-hoc networks without a serious amount of screwing around. Is it possible to create an "Infrastructure" network with my Dell Latitude D830's built-in WiFi - a "Dell Wireless 1395 WLAN Card", which I am assuming is probably rebadged Broadcom, or is there some fundamental difference between a wireless adapter and an access point that would prevent this?

  • Windows 7 unidentified network (or limited access) after hibernate.

    - by null
    My windows 7 network will show limited access or unidentified network after coming up from hibernation. In the office I normally use LAN connection, I turn-off my wireless card (DELL Latitude has on/off switch for the wireless card). When I back at home I will turn on the wireless card, but it will take about 15 seconds to detect my home WIFI and then show limited access. I will have to restart the notebook and it will be able to connect to my WIFI and internet. The problem will be solved if I restart the notebook, but that defeats the purpose of hibernation doesn't it? I have tried uninstalling the wireless card driver but still does not solve it. I also tried updating my network card driver but windows says I am using the latest driver. On support.dell.com also showing I am using the latest driver.

  • Large recovery partitions

    - by Unsigned
    Is there any good reason as to why factory restore partitions are generally much larger than they need to be? Examples I have found in my own experience: Dell XPS laptop Partition: 13.67 GB Used: 6.68 GB Dell Inspiron laptop Partition: 14.7 GB Used: 7.2 GB Toshiba laptop Partition: 15.3 GB Used: 9 GB In all cases, shrinking the partition to only slightly more than the Used space had no ill effects on future factory restorations. Why the exorbitant amount of extra space, given that neither of the three computers ever writes any data to the recovery partition? Is there a good reason I'm overlooking?

  • Unity 3D (with Nvidia driver) becomes very slow and laggy

    - by Graham
    How can I prevent my Unity 3D desktop from becoming slow after a while, given that I have an Nvidia Quadro NVS 290 graphics in TwinView mode? The desktop starts out fast on login, but becomes slow / lagging / hesitant / high latency after a while, symptoms being spikes in CPU usage by /usr/bin/X whenever I cause any graphical activity with the mouse or keyboard (e.g. typing, changing tabs, dragging windows). The desktop remains slow even with all windows (except htop in Terminal) and extraneous processes killed. Detail: Changing tabs in Terminal takes about a second, and X spikes to 76% CPU. As I type into Firefox, X spikes to 95% CPU. Dragging Termiinal window, X goes to 70% CPU. Basically, every graphical action sends CPU usage of X through the roof. Device: Nvidia Quadro NVS 290 Driver package: binary driver nvidia-current-updates (280.13-0ubuntu5) Dual Monitors: Pair of DELL UltraSharp 1908FP in TwinView (X screen 2560x1024) OS: Fresh install of Ubuntu 11.10 amd64 Desktop with all updates. Hardware: Dell Precision T5400 Workstation Pastebin of Xorg.0.log Pastebin of xorg.conf Pastebin of nvidia-xconfig -t output (easier to read than xorg.conf) Output of /usr/lib/nux/unity_support_test -p: To obtain the following htop screenshow I typed "asdf" several times in in this text box, alt-tabbed to Terminal and took a screenshot of the high X CPU usage. This also happens when firefox is not running: Quadro NVS 290 has "No" thermal sensor according to sensors-detect: Next adapter: NVIDIA i2c adapter 0 at 2:00.0 (i2c-0) Do you want to scan it? (YES/no/selectively): Client found at address 0x50 Probing for `Analog Devices ADM1033'... No Probing for `Analog Devices ADM1034'... No P robing for `SPD EEPROM'... No Probing for `EDID EEPROM'... Yes (confidence 8, not a hardware monitoring chip) I tried the nouveau driver by disabling the nvidia-current-updates under Additional Drivers, but Ubuntu and xrandr -q fail to detect the second monitor. This may be issue 737349. Funniest thing is that Nouveau wiki says that XRandR 1.2 dual-monitor is supported so it should work with a second monitor.

  • Brand new battery is 100% charged but at 0% capacity

    - by Chris Conway
    I just bought a brand new battery to replace one that had seemingly died. I followed the instructions that came with the battery and charged it overnight, then ran my computer on battery until it was in a critical state and charged it overnight again. Now the battery appears to be 100% charged and at the same time at 0% capacity—when it's plugged in it doesn't charge and when it's unplugged the computer immediately goes into low power mode. I've taken the battery out and checked the contacts. I've rebooted the system with and without the battery. Nothing seems to help. I'm not sure if I should blame the battery, the laptop, the charger, or the power management software for this state of affairs. The obvious answer would be the battery but I bought this battery because another year-old battery exhibited similar behavior—I assumed it was dead and a Dell tech came to the same conclusion. I'm loathe to order another new battery without first exploring other explanations. What can I do to diagnose this problem? Here's the /proc info: $ cat /proc/acpi/battery/BAT0/state present: yes capacity state: critical charging state: charged present rate: 1 mA remaining capacity: 0 mAh present voltage: 9754 mV $ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6600 mAh last full capacity: 6789 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 660 mAh design capacity low: 200 mAh cycle count: 0 capacity granularity 1: 66 mAh capacity granularity 2: 66 mAh model number: DELL WK serial number: 4043 battery type: LION OEM info: SMP

  • Dock with dual external DVI monitors with Intel + Nvidia Optimus?

    - by Ryan
    I have a Dell Latitude E6420 laptop plugged into a docking station, and the dock has 2 monitors (connected with DVI). Also note that I've installed Ubuntu alongside (dual-boot) Windows 7. I can't get the dual monitors to work both on Ubuntu (either 11.10 or 12.04) and Windows 7. When I run lspci | grep VGA, I get: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro NVS 4200M] (rev a1) If I then reboot and uncheck Optimus setting in the BIOS during reboot, I'm able to get the dual monitors to work in Ubuntu 12.04 (but I need to configure them every boot in Nvidia Settings). When I run lspci | grep VGA, I get: 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS 4200M] (rev a1) But then if I reboot into Windows (leaving the Optimus unchecked), Windows can't detect external monitors, and the resolution is unacceptably low. I've seen on many forum posts that this particular graphics card setup causes lots of headaches. I haven't been able to resolve my problem yet. How can I use my external display on my laptop with intel and nvidia video cards? How to use external displays with Intel driver on a NVidia/Intel hybrid system nVidia Optimus , Unity 3D and Dual Monitors "Just use VGA instead of DVI" isn't an option because my dock has only 1 VGA port (and 2 DVI). Switching the BIOS setting on every reboot and then reconfiguring the display settings every time is tedious, time-consuming, and impractical. Do you know how to make this work smoothly? Thanks for your help! P.S. see also: http://superuser.com/questions/434358/dell-latitude-e6420-dual-boot-ubuntu-windows-7-optimus-graphics-problems

  • Shutdown issue on persistent LiveUSB

    - by John K
    A) Downloaded Ubuntu to a Windows 7 temp directory from: http://www.ubuntu.com/download/ubuntu/download (Ubuntu 11.10 - Latest version / 32-bit). The output was a .iso file. B) Created a bootable USB stick using Universal USB Installer: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/. Did not select "Persistent file". Result: Tried it in a Dell Latitude D630 Dell laptop: works every time, many startups and shutdowns. C) Repeated B) but with "Persistent file" set. Works once or twice, but then, just locks on the Ubuntu splash screen. E) Downloaded LiveUSB Install from http://live.learnfree.eu/download, which created a file on Windows 7 called live-usb-install-2.3.2.exe. F) Ran the above installer with "Persistent file" to a 4GB ScanDisk (formatted) thumb drive. Result: Worked pretty good for a while. Shutdown and rebooted several times. Changed items like creating a new directories - all worked. Then: Setup an Admin account with a password and no auto login. On next reboot, it required the password and logged in correctly. Tried to shutdown via the top left icon - Shutdown menu option. Key issue: Would not shutdown, but would always go back to the login prompt. Could successfully login. Finally, shutdown (which just put me back to the login window), and hard shutdown with the power switch. Result: On reboot, just locks on the Ubuntu splash screen. Questions (note, very new to Linux): Did I shutdown wrong (I mean prior to the hard power off)? Is the persistence option very unstable, or am I doing something else completely wrong?

I kind of assume the thumb drive is just borked, but it could be my OS.

  • Ubuntu install can't find hard drives

    - by Casey Hungler
    I recently got a Dell Inspiron Special Edition 7720 computer. I am trying to install Ubuntu along side Windows. When I use the WUBI installer, the installation of Ubuntu works as long as I do not boot into Windows; if I boot into Windows, when I go back into Ubuntu, I am given a variety of error messages which claim to have corrupt or missing kernel/root directory, etc. I have been working with this problem for about a week, and have reinstalled Ubuntu MANY times. So far, I have eliminated all of the following problems: Corrupt WUBI installation (Downloaded multiple times, used on other systems), I have tried using a CD and a flash drive, both of which work on other computers. I know that no program within Ubuntu is creating the problem. I know that others have successfully installed Ubuntu on a computer with my operating system (Windows 7 SP1). This is a much shortened version of the original question, which has been up for about 5 days, and included a more detailed description of the problem, but left everyone clueless as to the source of this problem. When I spoke with the Dell service technician who came over today to replace my keyboard, he suggested that the driver for my HDD was so new that it was not compatible with the current version of Ubuntu. His reasoning is as follows: 1) During an install from a flash drive or CD, where I am supposed to get the option to wipe my system or create a dual boot, I get a window that asks me to select a hard drive partition, but none are listed. 2) This model of computer was made public in June of this year, while Ubuntu was released in April Adopting this theory, it would seem to me that the WUBI install fails after booting into Windows because Ubuntu can no longer find the files that it needs to load. Does this theory seem at all plausible to anyone? I just want to install Ubuntu and have it stay on my computer. I don't care how I put it there, I just need it to work, so I would TRULY appreciate any advice or suggestions anyone could give. Thanks so much for your time and support!!!

  • What to do about "system running in low-graphics mode"?

    - by ubuntubabe
    My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.
