OK, I've had a few of these with the no graphics issue and it was always a reflow or reball of the GPU.
Basically, I can barely see the "HP Invent" logo when I power it up. So I tried a known good LCD screen and it was also dim. No Backlight. I tried another known good one and it was dim also. So I'm absolutely sure it's a motherboard problem.
I do notice something interesting. The backlight will flash for an instant when the AC adapter is plugged in. It hasn't even been turned on yet and the backlight flashes. I believe that is some short of short since the power button hasn't even been pressed yet.
Any ideas?
