I suspect my v6545 has some motherboard problems.
It started with the inverter cable, which caused display issues. When I jiggled it and pushed it into the motherboard slot, it became alright; then followed wi-fi issues: "there are no networks to connect ", when indeed there were; and some jitters in the mouse, music and video and overall processing, meaning some CPU problem I would guess.
However, opening the case and not doing anything seem to do the trick and make everything work again.
problem is I've opened it 4 times already this past month, and it doesn't function as a laptop because I'm afraid to move it around.
should I change the motherboard? I'm convinced it is the motherboard, since I know the other components work fine as long as I jiggle them and push them into the sockets.
