If the laptop appears to boot up and the hard disk is spinning and the hard disk LED is flashing then the hard disk is OK.
Then the fault could be a faulty video cable or connector or CCFL lamp or inverter.
Try reseating the video cable/connector that connects to the motherboard first.
If this doesn't work then to determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

How can i get a free download of windows 8.


there is no such thing as a free download of a microsoft product
you may get a disc for win 8 but to make it work you will have to buy the licence to register it and that is as costly as buying the disc to start with
the only free operating systems are LINUX--ubantu and it is far better than microsoft when you get the hang of uing it

Will not start up


hi , Reuben

I would suggest you try safe mode.
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words "Safe Mode" appear in the corners of the display to identify which Windows mode you are using. If an existing problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one, to see if a program might be the cause of the problem.
Follow the steps to boot the computer in safe mode with networking:
1. Restart your computer if it is powered on.
2. Tap the F8 key after your computer initially powers on.
3. Once you see the Advanced Boot Options menu you can stop tapping.
4. Use the up/down arrow keys to highlight your selection.
5. Select Safe Mode with Networking and press Enter.
6. You should see drivers loading, and then please wait.
7. You should then be at the Welcome Screen.
8. Logon to your computer using an account with Administrator privileges.

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.

    Button keeps blinking


    It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at http://us.acer.com/ac/en/US/content/service

    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!

    Freezes on the warm boot screen MC9000


    This can be for a number of reasons.

    First thing would be to try and cold boot the device:-

    Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

    If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

    Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

    Hope this helps.
