It is with great interest that i have read all the posts concerning my Sony SVE 151A11W and tried most things. If i may explain. After taking out the battery for 30 seconds did help, because when i start it up i have now wireless connection, the HDD is running also the fans, the key board lights up like a Christmas tree. But the screen stays black and after a minute powers down, is there a chance that the ribbon connecting the screen to the motherboard could be faulty. I would be grateful for any help. Thanks Bill
