Take out battery open the port were the ram is installed ......remove RAM
you need a small piece of wire and a piece of tape
you will see 2 mount points with B500 or "xxx" above them
simply place the small wire across the 2 points install 1 stick of RAM plug into wall leaving main battery out fire it up and it may restart 2 or 3 times or you will immediately be in
NO JOKE did this exact process last weekend and it worked
