Me asus see screen is completely dark even though the power light is on. F6 doesn't help.

You didn't post the Asus Model or the OS you are using? Have you done ANY updates? Have you tried a System Restore to a date before this issue? When you restarted did you remove the battery?

sounds like it could be the screen has gone?

Hi

You do not say if your laptop screen is working or not or why you want to use an external monitor.

Assuming the laptop has no fault and boots properly, to send the laptop image to an external monitor, once you have booted into Windows, press and hold the Fn (function) key bottom left of your keyboard, near the Windows Logo key, then simultaneouly press the Function key (above the numbers) with the image of 2 monitors, 1 dark, 1 bright (often the F4, F5 or F6 key).

If the laptop's screen is faulty and the above procedure does not work, there may be damage to the graphics card which will probably require specialist repair.

I hope this helps.

Hi,
Check that the terminals in the battery compartment are clean and shiny. Remove any powder left after battery leakage. Insert fresh batteries in calculator. Make sure you respect the polarity diagram. +-+- (Many malfunctions come from incorrectly placed batteries).

After replacing batteries, calculator is restored to defaults and screen display may be too loght or too dark

To adjust the screen: Darken or lighten display

To darken screen
Press [2nd] key and release it.
Press and hold [UpArrow] until screen is dark enough.

To lighten screen
Press [2nd] key and release it.
Press and hold [DownArrow] until screen is light enough.

Hope it helps.

Try removing the battery and see if it starts. If the battery is dead, the laptop will be unresponsive as you described. If this doesn' work, then switch out the power adaptor. You can find these on eBay for less than twenty dollars. Your laptop is not getting adequate power to boot up.

Sounds like your backlight or inverter is on its way out. You can pick one up on ebay.  Google how to check backlight/inverter issues with your model.

Solution? - not sure yet but having read solution by Hector_ahab, tried various F() buttons in conjunction with Fn button. Pressing Fn with F6 switches between black and normal screen on my Acer Aspire 5920. Fingers crossed!

This sounds like a problem with your Inverter. Most PC/Laptop repair specialists should be able to sort this out with fairly little fuss.

Here issue is not clear, like if the issue is

1. There is no display on the notebook even though power LEDs are glowing?

2. There is display but very dimm/dark to see the display?

I will explain both the senarious, if the issue is something diff other than the above mentioned two, then you should get back to us by elaborating on the issue.

Solutions:

1. There is no display on the notebook even though power LEDs are glowing?

Sol: If this is the case, then try power drain:

Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

If the issue persists, then the issue would be with the motherboard components, you need to contact service center

2. There is display but very dimm/dark to see the display?

sol: If this is the case, then connect the external monitor to the notebook andcheck for the issue.

If the display is fine on the external monitor, and if you can see the display on the notebook screen by using the flashlight, then the issue will be with the back light of the notebook screen. Here also you have to contact service center.


Please reply if you need any further information on this issue.

either it is set to use an external monitor, or the backlight or inverter is bad
