I love the HP8470p and it has been performing solidly. But lately, there is something about the screen that's not working right.
Here's the spec: HP8470p; 12 gb DRAM (4+8); 256 gb SSD; 500 gb HHD.
Once in a while recently (more often now) when I move the laptop around (with AC plugged in), the screen will be all garbled, like in the old days when the TV station signed off and there is no signal. Hitting any keys doesn't bring it back except for rebooting. Pressing the power down button to shut it off and restart it solved the problem immediately.
Obviously, something is not right, or something is loose.
My initial reaction is that could be caused by the DRAMs. The machine originally came with 2x4 gb. I swapped one 4x with an 8x from another machine. Would there be any incompatibility that may cause this kind of problem?
Can someone point me to the right direction in repairing the issue?
Thanks.
