i recently purchased the Sony Vaio-Y and it had great features. as i cam across some issues concerning my device, i decided to update the BIOS as per recommended by vaio update. at the time of making an update,my windows 7 crashed. i was not able to boot , no vaio screen, nothing . The fan starts but shuts down after some time, the power LED remains green, and there is permanent blinking of HD LED . i don't have an sufficient idea about that . please help me in this issue as i am finding problems with my laptop.
