I had this problem on a certain brand of laptop,i finally refered to the owners manual to find FN-F5 toggled from the screen to external monitor depending on 1 click or 2 etc and that Fn-F1 put the screen into sleep mode the same way---im not suggesting your machine uses the same sequence keys but it might be worth a try finding out if you have accidently toggled your keys.
you could also be missing your OS or your bios boot sequence is incorrectly set--Press F2 whilst booting to get into boot sequence option of bios)-there navigate with tab or arrow keys--save and exit or reset settings to default and exit--dont change any thing in bios settings until you are familiar with how to navigate and select changes OK!

MacBook Pro won't boot at all


It's hard to say without more information. When you say it doesn't boot, does the screen come on at all? (the first thing that shows during a boot attempt is a gray screen). If the screen does come on, what does it show? Also what year is the macbook pro?

Apple macbook air won't turn on


Does the Apple logo or the Pinwheel show on the screen?

There is a problem with you OSX installation. Please boot from the Recovery partition (hold Cmd+R during the startup chime), and use Startup Disk to choose the correct hard drive to boot from.
You can also restore from a backup, and not lose your data here as well.

Hp pavilion dv9000 takes a long time to get past the bios screen. It won't boot of dvd either??


Check BIOS boot options and assign local hard drive as first for faster boot. This is also where you set CD\DVD as first to boot from disc. Look for F Key press on start up. It will be shown on screen. These can vary.

Many HP machines also have a boot menu option during boot. Again an F key and may vary.

Did you try pressing F8 key at boot up?

    Turn on your laptop and look at the first screen that comes up as soon as it is on. This screen will tell you "Press x key to enter setup", replacing "x" with the actual BIOS access key. It's usually "Del" or "F2" on Toshiba systems.

  • 2

    Press the key firmly and quickly before the screen goes away. If you do not react quickly enough, you will miss the window of opportunity to enter the BIOS. On Toshiba systems, this window of opportunity is somewhere between two to five seconds.

  • 3

    Navigate your BIOS configuration screen to the "Boot" tab. It is usually just before "Exit."

  • 4

    As the first boot device, select "USB," or "USB HDD." If you have a "USB ZIP" option, you might be able to boot from it, so select that if you have no other choice.

  • 5

    Press the button for "Save and Exit" in your BIOS. The correct button is usually F10.

    Windows wont start up when computer is turned on, at the bottom of the screen, it just says press f for set up or tab for bios memo, then the screen will be blank with just a cursor blinking


    If you are interested in solving the problem more easily and quickly. I think you can try this computer boot up suite, a boot CD and several other data rescue tools that help get your PC going even if Windows won't start or computer won't boot up at all.
