Hi,

My laptop was working perfectly when i last used it, but have just gone to use it today and it is unresponsive. The ac is plugged in and there is a green light on the power box but the laptop won't start. I've left it plugged in, incase it's run out of battery, but there is no difference. 

Any ideas? It's only 8 months old and I am so frautrated right now. 

Have been dissopointed with it since purchase, as it is terrible for picking up wifi signals unless you are in the same room as the hub (where as my old laptop could pick it up in any room) and now it won't even start. This is my first sony product and the most expensive computer i have ever owned, so am beyond disillusioned with this.
