Anyone knows what this PCB is called?

Laptop's a Qosmio G20.

PCB is circled in red in first picture. The second picture is a close-up (where the reason why I want to know what it is is quite apparent )







Thanks.

 

Bump

Btw it's directly below the touch-pad, has got pins leading to the battery (which is long-dead), 6 small black wires leading to a molex on motherboard, and then there's the thicker black wire encasing a lot of smaller ones going to motherboard as well.

The problem with this laptop is graphic glitches. At first there was a black "side-bar" on the left, showing from the moment the laptop is switched on.
Then later it started showing garbaged words on startup, windows didn't load and after 5 minutes it rebooted. This looped on.
Weirdly enough it does boot in safe mode (had to guess where the option was in the garbaged font) but always with a black vertical sidebar.

I'm pretty sure the problem is not from the lcd since it does exactly the same thing when hooked on an external monitor.

 

That PCB looks like a breakout PCB. All it does is just extend the current PCB into another area. Not exactly like a daughterboard, but kinda in a similar fashion.

I think it connects to your battery and your touchpad (?? on the last one)?

At any rate, screen messing up has only three causes:

LCD broken
GPU broken (the actual die, the package, or the package-->PCB link)
Drivers


IMO, it doesn't seem related to the circled component.

 

Thanks for the reply.

I don't think it's an LCD problem since using an external monitor does the same thing.

Unfortunately the 6600 nvidia is soldered on, so I think there's next to no hope of getting it to work again
