Hi folks, I've had my M1330 for about 2.5 years now and recently the AC adapter stopped being recognized by the laptop. By this, I mean that it no longer charges the battery or runs purely on AC power without the battery in. The light on the power brick still comes on; I've also bought a new PSU and tried this but no luck. The battery indicator doesn't show any problems and I can still run the laptop on the battery (although it's down to about 15% charge now). I managed to get it to recognize the AC adapter by wiggling the cable a little at one time, but now no amount of wiggle works. I'm at a bit of a loss as to why this happened or what is the cause, but I'm starting to think it's a problem with the power connector on the actual motherboard.
