This is an HP DV7, I7-2630QM, 6GB, 250GB laptop. When it boots it does this beep which is a single long beep of at least 10 seconds or sometimes more. I also get a text message on the lower left of the screen which says to touch the Esc key to bring up the startup menu. Nothing changes when you push the Esc key, but when it decides to quit the beep, it boots as normal into Windows as if nothing had happened. It doesn't allow access to the Fn keys, and I can't find a way to get into the BIOS. I have done all of the suggestions in the Sticky pertaining to power up problems. Different power source, re-seat memory, replace memory etc. This item does not yet have a battery. One is on order.
