I HAD the same problem...if you run your laptop on your battery AND your mains, take the battery out and run it off the mains alone...then see what happens.

Could be a bad screen--did it just happen? Had you noticed any weird behavior prior to it going dark?
I believe your computer does not have a separate video card, so that leaves either the display panel or the inverter (provides power to the display panel) as the culprits.
Is the computer still under warranty? If not, you'll have to make the decision whether to fix it yourself or take it to the shop.
HP has a service manual on it's site to show you how to fix it.

See if you can get into safe mode, hit f8 before it re-boots, if you can the fastest way to fix it is to just do a restore. Start, programs, sccesories, system tools, system restore, take it back to the last time you are sure everything was working correctly, and let it restart. Hopefully that is all that is wrong, either a bad video driver or system file. If this does not work and you still have a blank or black screen, then you will require more assistance. Did you install anything between now and the last time you it was working right? Worse case scemnario you blew the lcd, but let's not go there yet.

Laptop hp6730b when powered on the flash lock iconA and the flashing icon1 appears and the screen is black and want boot


Being an Hp, it has overheated and unsoldered the GPU from the board. Remove the main board and send it away for a GPU re-balling repair. Take a look on ebay for the re-balling service in your country.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

HP Pavalian laptop screen gone black and blank.


It seems like the lcd back light may have failed can you see a faint image on the screen when you look really close, try it with a torch. If you dont see even the faintest image the inverter has failed and needs to be replaced. If you look on youtube again and search for videos of replacing both the back light and the inverter it will give you some info on how to change them. Do a google search for hp spares and you will probably find what you are looking, i think the inverter is about £30 and the back light is bit cheaper. hope this helps.

HP Laptop power lights go on, but the screen is black


That happened to me before, i just took out all the removable chips from underneath the laptop (you have to unscrew and take off the middle of the bottom plates) and i put them back in tightly. It worked for me so its just an idea
