I inherited a VGN-SR190 laptop from my niece. I cannot connect to the internet unless I am hardwired. Can this be happening because there is a dead battery in it?? It shows I am connected and have excellent reception but it will not connect to the internet. I am stumped and curious about the battery. I am afraid to purchase a battery online as they all have horror stories written about them. Thanks for anybodys input or thoughts!!
