If the machine is only needing what you describe, you should get the HP splash screen, then a black screen with a flashing cursor, and the message no operating system found, or no hard drive found. If you get nothing, the PC has other issues, probably the motherboard.
I was given an hp g60-120us laptop. It doesn't have memory sticks, a hard drive, or battery. When, I turn the it on there is nothing on the screen. There is the power light and ac light on. I push the F10 key but it won't go into bios. Is the board?
