My screen is black i havent had any problems new battery and adapter i shut it down woke up and its a black screen and cant see anything its never happened before i have no idea and ive had it for 4 years dell 1521 inspiron

Do you see anything? No "ghost image"? A white cursor in the top left? Any damage ? Drop? Jarred? Bumped? May be backlighting, inverter, lose ribbon cable, bad graphic adapter. Can you attach a external monitor to verify the graphics adapter? Take a look at this video for ideas: http://www.youtube.com/watch?v=2Yi6GNFcP3w Remove ALL media from DVD rom, usb, etc. shut down, unplug, remove battery, plug in, reboot. Any change?

try using a cooler pad for your laptop for heating issue,
try changing the RAM also sometimes the faulty RAM also does this

In my experience, i will press the power button(if my battery gets too low and the screen get black), then the laptop will get to the previous screen automatic As the set of my laptop is that, when I closed the lid, laptop will go to sleep but not turn off, and the laptop will woke up after I opened the lid. try and to see anything helpful?

Perform the following:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

If turned on, shut down the Notebook, insert the Battery and turn it on again. That's it.

Cause:
With an extensive use of the notebook, some times notebook would store some static charges which indeed will stop the notebook from powering up or charging the battery.

Performing above procedure will not effect any personal data or delete any pictures from the hard drive on your notebook.

Check your video adapter settings. try to set it on clone and see if the picture would appear the same on your LCD. From there you select it back to your LCD. Just make sure the primary display is set to your LCD and apply the changes.

Hope this helps.

Hi,

Check fuse in plug first...!

Take the battery out and then plug the power adapter in and try to power it on, if it comes on power the laptop off again remove power adapter and put the battery back in and plug the power adapter back in.
If it didn't power on or light up on the laptop then the power adapter has gone faulty, buy a new one.

Power it on again, if it doesn't power up at all and there are no power lights the battery has come to end of its life.

If it powers on fine, then it just locked up, one of those things.

Thanks

plz ask your vendor for help because it is under warranty

Try this -- it is called a Power Drain Procedure -- HP technical support helped me with this --
1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

hold the home and top buttons and the ipod will reboot itself.

remove battery and try ac-power if laptop boots up then battery need replacing but if no laptop bootup then take it to be repaired and tell the tecnition what happened and he or she will try other options to get you going again. good luck on problem.
