Question about Computers & Internet
A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode, if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.
Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness. Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over. Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop. Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced. Hope this helps

I had the same problem when I first bought my Acer Aspire One a few weeks ago. I searched the web for answers, but it didn't really seem like anyone had a solution. However, one guy on a forum or website said something that gave me an idea - he said something like: What's the problem? Just open it up, hit the power button, type your password, and it wakes up.
Well, that didn't seem helpful to me at the time that I read it, but after thinking about it, I had a hunch. I had not set up my netbook to have a password (yet). So I did. And it's been waking up from sleep mode like it should ever since!!!
Hopefully, if you're reading this, setting a password will work for you, too. If you don't know how to set a password, here goes... Start...Control Panel...User Accounts...Change an Account...[Pick your name.account]...then the option to create a password should come up. Let us know if this works for you!

Try removing the battery and using only power cord to turn the laptop on. If that fails, try turning it on without power cord, just on battery.
If none of those work, then most probable cause of your problem is motherboard. Hopefuly you are either under manufacturer warranty or you have extended warranty with your vendor where you've purchased the laptop.
If your laptop turns on on power cord, but without battery, then battery is the problem. Also, if laptop turns on when it's only on battery but it doesn't when you plug ac cord in it, then the adapter is the problem.

Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.
This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation.
Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money!
Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow.
The Shut Down menu appears.
Point at "Sleep" and click on this option.
Your Windows 7 computer goes into sleep mode.
Wake your computer from sleep mode by jiggling the mouse.
There may be a delay of a few seconds before your hardware powers on.
All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode.
Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time.
Click "Start" and select "Control Panel." Click "System and Security."
Click "Power Options."
A menu opens.
Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode.
If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity
