Hi,
I have a HP Pavilion N4515 Notebook that will not boot. When I turn it on the lights go on and I hear it begin to run, then it turns off. It makes no sound to indicate any failing parts. I have tried it with the battery in and out. I have removed the HDD and tried it, also swapped with another HDD and it does the same thing. I have taken the CPU cooling unit out and checked that the fan was working, it is. When I took RAM out it sounded several beeps to indicate RAM was missing. I am not sure what I can do to continue with the diagnostics.
Thanks
