I have a Fujitsu Amilo Li2727 laptop which won't boot. I have checked to see if it could be a faulty hdd, ram or graphics but to no avail, they are not the cause. I have also checked the usb slots but all seems to be in order.When I tried to boot with just the battery, same result as with mains, the battery light flashes orange and no post. All the other lights are green.
