I have an HP Pavilion dv6 laptop that will not boot up. Or at least nothing is displaying on the screen. Pushing the power button seems to start the boot-up process but there is absolutely nothing displaying on the screen.
I tried plugging it into an external monitor via VGA cable but nothing displays on the external monitor either.
Tried pulling the battery and holding down the power button to clear out the CMOS. Didn't help.
Tried pulling and resetting the RAM chips. Didn't help.
If I pull both RAM chips and then power it on, I do get the CMOS beep error codes indicating that no RAM is present.
The cooling fans are powering on and there are two lights around the keyboard (one to the left of the Caps Lock key and one right above the End & Pag Up keys on the number pad) that blink in unison. Other than that, not getting any useful response from this laptop.
Sounds to me like either the video card or perhaps the entire motherboard is malfunctioning.
Would appreciate some ideas on troubleshooting this further. Thanks in advance.
