Hello, I have a HP Pavilion dv7-4177nr Entertainment Notebook. I have not recently installed anything new. My problem began several months ago.
If I shut down, hibernate, enter sleep mode, or have a battery drain down, it will not come back. Everything starts to run like normal, (fan, disk drive, dvd drive, ect), but all I get is a black screen and the l.e.d in the caps lock button blinks once, every couple seconds or so. It takes anywhere from 20 minutes to 30 minutes of me constantly turning on (while pushing the fn and f9) and turning on before it comes back to life. Once on, everything works fine and or normal. It allows me to install updates and restarts like its supposed to do. Just dont let it turn off. I apprecaite any help cause I'm sure leaving this running all the time cant be good.
