I’ve had a laptop for about a year now, first time user. It was fine for about eight months until the power started flickering, didn’t think to much of it, it didn’t happen a lot though it gradually got worse and to the point where it wouldn’t charge if the power flickered off, it would drain the battery until it switched off and then started to charge until the power was flickered off. I sent it back for a repair, and they replaced the motherboard, didn’t tell me what had gone wrong and it was fine again until this month barely four months on. (unfortunately warranty expires March 15th) I caught it at the beginning stage of what happened before the power flickering intermitely at times. It’s currently back in for repair. I was speaking to someone I know and he told me it would be a problem with the tracers lifting off the board through excessive pressure to the ac adaptor port, and he gave the example of his wife throwing it down. That’s something I’ve never done, and the only pressure I realize may have been applied is when I hold the laptop at an angle to the surface that it’s on, the back tilted down, though I’d imagine this wouldn’t be a lot of pressure. Is this a frequent problem with laptops, am I at fault with the position I rest it on or have I just bought a dodgy laptop?

It sounds like a loose connector in your adaptor port, if you notice any wiggling or looseness when plugging in, this is bad, as the laptop environment is so densely packed. When you plug in, the port (if loose) could be shorting your battery connection as well. I would insist that this be double checked as typical laptop hourly bench charge rates are cost prohibitive.

That's exactly it, it's able to 'wobble and wiggle'. Also the adator port was getting extremely hot. After it was returned from the repair in December it was non-wiggly and seemingly in properly without movement and gradually went back to the loose stage it's now. Thanks for answering. Do you know what the course is? As I said above someone I spoke to gave the example of exessive pressure by his wife throwing it down, though it's nothing by rule that I do. Is the angle I occasionally held it at, at fault? It seems incredibly fickle it is.
