    power is on and you can hear windows starting up but the screen is black. There is no sending it back it is like 4 years old.

    Does your computer indicate signs of being powered on?

    If not, you might have to send it back.

Look at the screen closely, if you can see the image but only very faintly, there is a possibility it is your screen's backlight because the laptop is older than 3 years. In this case you have to replace the ccfl bulb of the screen. It is a difficult repair but it can be done, if you look for guides online you will find something. I work for company that does Laptop repair in NYC and we do this repair frequently. You can get exact ccfl lamp for your screen type on ebay, Make sure it the right length of the bulb.

It sounds like the Backlight for your laptop gave out.

Heres a simple test to see if THAT is the case

Power it up while under a bright light 100W or better possibly even sunlight on a sunny day. Move the screen at varying angle to the light. If you can see what appears to be a "Shadowy" image of your desktop then YES indeed your backlight went out.

Your backlight should be replaced by an experienced service tech. Unless you are comfortable with working with high voltage electronics (The backlight has a charge capacitor) that can injure you if you are not careful.

There is a VGA connector on the back of your laptop. You can plug in a monitor to that so you may use your laptop. (Until you can get it fixed) Just plug in the monitor and press <Fn> and <F5> to switch to the external display

Hope this helps

How do i get the computer out of hybrination on start up


First is to press the power button like you would normally do to power up. If the battery is too low in charge you may have to bring it up with the charger to a minimum charge so it can turn on. Another idea is to hold the power button for 5 seconds, giving it time to fully shutdown then power up normally. If that isn't the answer try removing the battery if it's a laptop and reconnecting it, connect the charger, wait a few minutes if the battery didn't have a good charge and see if it will wake up.

Some computers may not wake up in certain hibernation modes but most will if the BIOS is set for S3 hibernation mode. Obviously it does have to boot to check that.

Cant get power saving mode off


Step 1:
Sleep Mode b> Sleep mode is primarily used with home computers (desktop computers). Sleep mode is designed to save the current work, programs, and settings of your computer using your computers memory, while using very little power. b> Hibernate Mode b> Hibernate mode is primarily used with laptop's. Hibernate mode is designed to save your computers current state on to the hard disk, then turn off your computer to stop using power completely. This mode is usually used when you do not plan on using your laptop for an extended amount of time. Benefits b> Using Hibernate mode is more power-efficient, but files may become fragmented over time by using this mode frequently. Sleep mode does consume more power, but the advantage that Sleep mode has over Hibernate is that it does not take as long to resume your computers former state when you are ready to continue using it.

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 accidently shut my computer down with hibernation before leaving. When I come home, the computer will not turn on, no lights no noise, nothing. How do I unlock the hibernation? Or could it be something...


You need to hit the power button just the once to bring it back out of hibernation mode. It may take around 30 seconds until you hear your computer starting to boot back up and a little longer for the screen to come on.
Failing this, you can try a hard reboot by holding down the power button until you hear your computer re-boot. Usually you need to hold around 10 seconds. However using this last method as a final resort will result in your computer telling you that it did not shut down properly.

You might have put the computer into hibernate; have you tried pressing the power button? It should wake the computer up if it is asleep or hibernating. It is also possible that your monitor cable is unplugged.

Look at the cd drive. Next to the button that normally opens the cd drive is a pinhole. Power up the computer. Using a straightened paper clip, push the paper clip into the pinhole. you should be able to get the cd drive to open.

If you can not get the computer out of sleep mode you should now be able to get the cd drive open and use the recovery disk.

Hi Stewart,

Forgive me if you've already tried this..
If you think it has been charging long enough, then try holding down the power button for about 10 seconds to fully power it 'down' then hit it again. It might have went into a suspended state or hibernate mode.
Worth a try..

Hope this helps

My acer computer will turn on but wont come out of hibination mode


Some laptops have issues with Windows XPs hibernation mode. To get the computer back up again you should just hold the power button down until it shuts off completely. Some laptops won’t shut off even if you do this. When this happens you have to take the battery out to get it to turn off. Make sure it is not plugged into the wall when you do this otherwise it wont work.

Once you get the computer back running again you may want to disable hibernation if it seems like its going to keep happening. Go to Start, Settings Control Panel or Start, Control Panel and go to the Power Options icon. Change the hibernation section to never. You may want to try standby as an alternative. Standby saves all your running applications and documents into RAM while hibernate saves them to the hard drive. Hibernate uses less power from your battery, but it will take you considerably longer to get the computer back up. If you always plug the computer in then you may want to disable standby and hibernate since you really dint need them while plugged in.

Let me know if this works.

Disable hibernation in the power settings. I've run across many computers that do not respond properly to hibernation mode, and that do the same thing. It's easier to simply disable hibernation mode and have it fall into sleep mode instead.
