Of course Best Buy just kept saying it was a virus and they needed to install "their" software to fix it (it was before we got married, I had not yet become the family tech guy yet). Of course after a bunch of trips they finally admitted it wasn't a virus and surprise! it was out of warranty. After googling it apparently it was a problem with the ball grid array (??? no idea) that HP won't acknowledge.
Never again. My next laptops will be Macs. |
Ball grid array is a way of making contact between an integrated circuit and a printed circuit board. The IC is made with tiny little balls of solder for its connections, which then melt to make a connection with the circuit board when heated. It's great when it works.
If this isn't done perfectly right, then the connection could be loose, and flexing the circuit board could make / break contact. That's probably what you were experiencing.
I don't know when your laptops were made, but there was a time when the entire electronics industry was going through reliability problems due to the introduction of new processes such as lead-free solder and water based cleaning.
