Vaio SR490 Power Issues

So my brand new SR490 is already having some weird power issue. What happens is, the adapter stops powering the computer. This started happening randomly last week. I would be sitting there on the computer, and the screen would dim (I have it set to do this when it goes onto battery power). I would move the adapter around, make sure it's plugged in right, but that didn't change anything. After a few minutes, it would switch back to AC power by itself. It was worse last night, when the battery actually died because it wasn't getting a charge. The computer was just sitting on the desk and it kept switching between AC power and the battery. I even tried different outlets, it seems to have nothing to do with the AC adapter. I switched the battery out, it has nothing to do with that either.

I turned the computer off and plugged it in, and behold this morning I had a full battery!

I called tech support and of course the Vaio wanted to behave and I couldn't replicate the problem. The only thing they could come up with was the DC jack. He didn't seem too sure though. A tech is coming to fix it soon so we can see if that works.. but I wanted to see if anyone here had any other ideas. Thanks!

 

I have a problem with a old power adapter (not the connection to the wall outlet, but the connection from the laptop to the power adapter). It is pretty old, and I guess some stuff is frayed inside, so in certain positions it will fail to power on, and I have to move the adapter around a little bit before it can establish a good connection. But it sounds like you have all new components, so hopefully the tech can fix it!

 

yeah i have had that with all my old laptops! this issue doesn't seem to have anything to do w/ the adapter because it doesn't respond if i move it around. so we'll see!
