Hp L1820 moniter not on

I left my computer on all day and came home to a black screen. I moved the mouse, not response. I pushed enter, and still nothing came on the screen. I had not choice but to push power and re-boot it, but I was surprised to find out that it still wouldn't show any signs of life (the moniter that is, the computer itself is responding) Please help this poor girl!

Mouse cursor disappear on hp w2371d

See this...
If it only disappears when you move it left or right off the edge of the screen, your video software may think you have a second monitor. Tell it different.

How do i reset my dell latitude x12 to factory settings

Hi Steven,
Boot the computer and watch for the black boot up screen. It will only show for a few seconds but somewhere through the boot process, a line message in white text will say...either 'to enter the bios press F2' or, 'to enter Setup, press F2'.
The F buttons are on the top row of your keyboard.
So press F2 at the appropriate time and you will find yourself in the Setup area. The graphics will look cruder than usual - that is normal.
Your mouse won't work to allow you to move you around in there, so use the keyboard arrow keys to move the cursor and 'return' to open other options and follow the instructions to move left, right etc.
Look for a command 'Restore Factory Defaults and Exit?' toggle to it to highlight and Enter. Then enter a 'Y' for yes, Enter again and the PC should re-boot and be as good as it was on day one.

Within the last few days the moniter "blue light" when it is turned on suddenly turns yellow and the screen goes dark. I move the mouse briskly and turn the moniter off and on again and...

You should check the "Power Options" when the computer "Sleeps" & "Hibernates". Go to the "Control Panel" if you Win 7 or below, if you have Win 10 just type "Power" on the "Search Box" on the bottom left of the screen and then click "Edit a Power Plan" and set when the Computer "Sleeps" and when it "Hibernates". Basically when you move your mouse you are waking up the Computer from "Sleeping" or "Hibernating". Goodluck.

    Left button of vaio mouse does not work anymore. any idea how to fix it? thank you!

    Try the mouse in a different computer.
    If it works, it's the "settings" for the mouse in your copy of Windows that have changed, i.e., pushing the LEFT mouse button is *NOT* "associated" with any specific "action".

    Or, shutdown your computer.
    Disconnect the mouse from the computer.
    Flip the mouse over.
    Look for any screws holding the mouse together.
    If you find some, undo the screws, and split the mouse apart.
    Inspect the mechanism that "clicks" when you push the LEFT mouse-button.
    Remove any dirt/dust.
    Reassemble the mouse.
    Reconnect it to your computer.
    Try it.

    If it still does not work, try the mouse in a different computer.
    If it still does not work, responsibly recycle it, and buy a new mouse.

    Moniter is only shows self test e173fpc

    It sounds like your video card may be kaput. Can you try another monitor on it? If you use a monitor that you know works, and it does the same thing - then your video card has failed.

    Alternately, you can try a different card and the same monitor.
