    Sounds like your charging system is okay but your display isn't working. Do you have a spare monitor you can plug into the back of your laptop to see if that works?

Why is my screen blank when I turn on my computer?


Before starting your laptop up... try to remove and clean the connector surface of the memory card/s with pencil eraser,soft cloth or tissue paper. Then insert the memory card/s back properly. check the unit if it is booting up nicely.

My HP 6720 won't switch on. When connected to the power source, a steady blue light comes on (normal) then goes to a light blue then goes blank. If I press the 'on' button, a flashing orange light appears...


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The power button could be bad.
5. The motherboard could be defective & needs to be replaced.

BLANK SCREEN ON MY hp compaq nx9420. my laptop was working fine and then when restarted I got a blank screen. The power LED and cahrging LED both light up but screen remains blank. have changed the video...


Did it display any video at all with boot options or HP logo? Any POST test or beeps after you started the laptop?
Try removing the power ac adapter and battery. then only boot it up with just the AC adapter (no battery).
Good Luck, JAJ

Was cleaning dell laptop screen and it went dark, is there a switch To lighten it back up?


Look on the function keys for a delicate blue description ... press the fN key and the brightness increase key.

I doubt you accidently unplugged the screen ... but dont discount that totally.

Good luck to you

Is the lightening bolt supposed to flash orange? The battery will not keep a charge at all, so I have to keep it plugged in all the time. Does the orange flash mean I may be in danger of losing files, etc....


The orange flashing lightening bolt is confirmation the battery does not charge. It is not an indicator of any other hardware failure.

You can remove the battery if you find the flash annoying. The laptop will be lighter without the battery too!

HP 550 Note book will not start


  1. Take out your battery and the power button for about 60secs.
  2. Start the laptop using the Adapter [without the battery]
  3. Lighten up your laptop...remove any external device attached [printer,scanner,pen drives etc.].
  4. It could also be a RAM problem,try changing the RAM if you have two start with one and exchange them.
After that when the system starts you can do the system restore START--ALL PROGRAMS--ACCESSORIES--SYSTEM TOOLS--SYSTEM RESTORE to restore it back to an earlier date when laptop was ok. THEN LATER ON PUT THE BATTERY BACK IN.
  • Try restarting after an hour gap.
  • If this doesn't solve your problem call the company people.Their might be a Video Card problem or any other internal hardware problem.

Hp pavillion will not turn on, took battery out and put back in still not working. blue light around power cord on and blue lightening bolt flashes


Hi Iceprincess5

The three flashing lights indicate the battery is dead. Since it still wont power up with the cable plugged in I'd say the port has gone. Try wiggling the adapter about in the port to see if it begins to charge. If not then you would need to take it to a laptop repair centre to get a new dc port soldered on or buy a docking station.
