Hello,
One day I was surfing on internet and suddenly my sony vaio laptop stopped working. I tried to restart it but nothing happend. There is no sound no light absolutely nothing. I tried different power cord and also tried another battery but nothing happend. Is my motherboard gone? How can I take its backup? I tried to open it but it looks impossible for me. My model is PCG-z505 cr/k (japanese model).
Please help me!!!
