Did you try pressing a key? Sometimes laptops need a key pressed to come back from hibernation...

Is your computer setup to go to sleep when you close the lid?

Click on start -->control panel-->power options and then check the option that says choose what closing the lid does. You have to change this setting to 'do nothing' if you want the computer to stay on when you close the lid.

Compaq presario cq61 screen went dark but can still see window faintly through the dark sreen.


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If no luck, try to remove battery and drain the power, then replace battery and turn on.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

My dell inspiron laptop 1000 screen turns dark every few seconds. if I close the computer half way and open it,it stay bright for a few seconds and turns dark again


This is your back light on your lcd display, To prove that have a flash light handy when it goes dark point the flash light at the screen and you should see the screen and that would mean right there you got a back light going out or the inverter that powers it is going bad. Etherway if this is not your area of work you need to tech it to a computer tech local to have it repaired.

Thanks for being considerate with your ratings and feedback today.

Dell ADAMO 13 w/Vista 64 Random power failure...goes dead in 1 second. Battery fully charged. Happened with external power and when on battery. I have latest BIOS v6.0. I ran pre-boot diagnostics...


If the power totally fails (i.e. power is cut off, LEDs turn off, fans stop, ... etc), then this more likely to be because of a short circuit developing in a failing semiconductor component, or a power supply problem.
However, if the laptop is still running & only the display on its LCD is cut off but the laptop itself stays powered on, then your laptop might be experiencing a failing screen inverter board, a failing screen backlight lamp, or a failing LCD screen cable.

TYPICAL INVERTER FAILURE SYMPTOMS

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Dell Inspiron 1300 - When I re-open the lid,Screen stays Black !


Your laptop either goes to hibernate or sleep mode when you close the lid. Then, when you open the lid up, the screen is still off because your pc already hanged/froze and could not wake up at all (usual problem in vista). Off course, hard shutdown would fix it. But actual fix is under power options on your control panel. Check your current scheme and edit it. There are options there that you can select to "do nothing when closing the lid"

Hope this helps

HP Compaq nx9030: screen ON only in to lid position


Wow.
One of two things.
Either your inverter gets unpluged (therefore it isn't plugged in correctly in the lappy) unless it's moved to a certain position (so don't shake your lappy or else you might see nothing), those being positions where theres slight pressure on the connector, even though it's loose or unplugged (POSSIBLY faulty, but most likely not, if it turns out it is, other than resoldering it, you'll need to return it for a fixing up.)
Or
The switch that turns your screen off when the lappy closes is faulty (if it's located near the back of your laptop, aka. under the lappy's LCD bezel.

Opening it up and unpluging and pluging in the inverter is probably what the solution is. A tech might do it for free if you're nice (or you could do it yourself, don't loose any screws :) )

Hopefully it is just a loose connection and isn't a big deal at all to fix.

Stay Spicy and Happy Lappying!! :) Don't forget to rate!! :)

Screen going blank and laptop freezes.


Go into the diplay properties, under the screen saver tab there is a button marked power, open this. Under one of the tabs there is a section that reads, when I close the lid, under this section set it as never.

Open/Closing


CONTROL PANEL --> POWER OPTIONS --> ADVANCED TAB

Select "When I close my lid (or something to that effect)" and change it to "do nothing" or "ask what to do". There is nothing I hate more than a misbehaving hibernation mode!
