Question about Computers & Internet

Laptop screen Hi. When I turn on my laptop, the screen has a red tint to it. It flashes a couple times and goes black. I have connected it to a different monitor so I do know that the computer is ok and it is a screen problem. How do I know if it is a led bulb or some other problem?

    My screen went black so I removed the cover and detected that the video card has a little grey disk with copper wires wound around it had fallen off. I think that this might be my problem. I can't find one anywhere. Help

If you are comfortable with removing the lcd bevel from your laptop, you can check to see if it is the flex cable itself. Above the keyboard between the f1-f12 keys and the actual LCD screen itself is a small plastic strip that covers the LCD flex cable, as well as often contains various case screws that keep the unit together.

If you are careful, it should be mildly easy to snap out the small plastic anchoring hooks from the sides and center of the strip and remove it. Underneath that strip you will find a somewhat thick cable that looks like it is wrapped in micro-chain link tape (it's actually electromagnetic shielding tape). Trace the cable to where it connects to the computer near the keyboard, gently detach the socket, and re-attach it to ensure that it is properly connected. This is not something you should have to do, but if you are troubleshooting for the cause of the red lines on your screen, this is the most probable cause.)

The cable, the connection, or the on-board video card itself could all be culprits as to why you are experiencing distortion. My secondary recommendation if you do not feel inclined to open your laptop yourself, would be to take it into your local Best Buy and have a geeksquad technician check your unit to make sure your drivers are properly installed and it is not a software issue. Also, if you have a warranty that covers the unit for repairs, it would be convinient because you would already be at the store.

Hope that helps.

How do i turn off the HDD


What happens when entering the sleep mode is the drives will be turned off and the present state will be kept in memory until awakened. While the system is active the power scheme will prevent the drives from idling down after so many minutes with the never turn off setting applied.

With the turn off drives after the default 20minutes of inactivity that doesn't mean all drives turn off at the exact same time. I've never come across any reference for changing the power plan option for individual drives. But I can point you at the guide for the power plan settings with one instruction on drive settings to apply prior to entering the sleep mode.



hope that helps if not let someone here know.

How can i download falsh player on to 2011 imac desk top threw Linux ubentu browser ?


Ok, there are a number of issues with you spelling so I am going to assume you meant the Ubuntu OS. If that is the case the Flash Player install is done by the following:

If you are using the more modern versions of Ubuntu, simply install the Adobe Flash application from Ubuntu Software Centre.

If you are using a version that does not support the Software Centre, try:

Go to the Adobe website.
  • Click on "Download the Latest Player," and choose ".deb for Ubuntu" from the drop down list.
  • Choose "Save File" from the pop up window.
  • Open a terminal window.
    The terminal window will be found under Applications -> Utilities.
  • Change to the directory where your downloaded file was saved.
    cd Download
  • Install the libcurl3 library: sudo apt-get install libcurl3
  • Install the Flash Player: sudo dpkg --install install_flash_player_<version>_linux.deb
    Replace <version> with the latest version number.
  • Restart Firefox.
  • Check that Flash Player was installed.

    Screeen is upside down


    If you have a Windows OS, press and hold the ALT and CTRL (control) keys and then press the Up arrow. (If that doesn't work, try holding the Alt and CTRL keys and pressing the left (or right) arrow key twice.) If that fails, right click on the desktop (Windows+D will minimize all programs), anywhere with no running programs or icons. Then select the Screen Resolution option. Look for the line Orientation; use the drop down menu to select the correct orientation. Click Apply and then confirm the setting change if a confirmation window pops up. (This works in Windows 7 and 8.) For older Windows versions on laptops, you may need to select Graphics Properties (or a similar line) and then repeat this. The Windows screen rotation option is dependent on your video card. With some models, you'll need to open the graphics card properties to undo the rotation. You should see a line for the graphics adapter when you right click on the Display.

    For Macintosh OS, make sure that the System Preferences is closed. Then open it by pressing Option/alt + CMD . Select the line Display. Find the button labeled Rotation: Standard then choose the correct screen orientation.

    I hope this helps.

    How do i reset my computer to an earlier date?


    Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

    Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

    Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

    I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
