Question about HP Pavilion dv9000z Notebook
My screen has gone totally black. rebooting doesn't help
The most likely problem in this situation is that the inverter is burned out. Do you hear sound? If your computer boots and there is sound, it is definitely the inverter board. You might want to try to replace the inverter board. I think it's about $15 on ebay. If you are tech-savvy you can take the computer apart. The inverter is usually located below the LCD screen. for more info on replacing the inverter click here http://www.insidemylaptop.com/remove-lcd-screen-inverter-board-hp-pavilion-dv9000-laptop/

If its only 3 mnths old should still be under WARRANTY take it back
if its not under warranty
Turn Off the computer now as soon as you hit the power button, keep on holding Alt key & keep on tapping F10 key ie: Alt+F10, it will open the recovery console select full factory restore and follow on screen instruction. (Note:this will erase all datas on the computer) or
During the boot process you will see on the screen to press a certain key to enter setup usually delete or the F2 key this will differ depending on which bios you have
Press and hold that key during the boot up process to enter BIOS using the arrow keys you can load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart
hope it helps
