the laptop doesn't see a (functional) hard drive; that's why you get the fixed disk failure message.
the drop may have just dislodged the hard drive from its connector. turn it off, open the bay, pull the old drive out and put it back in. then turn on the laptop. if it still complains, turn it off, put in the new hard drive and turn on the laptop. if you still get the fixed disk failure message then the mainboard or some other component is damaged.
my son dropped the laptop on the floor and now when we turn it on the fan stops working a few minutes after and we got a message:
error 0200: failure fixed disk.
pres <f1> to resume or <f2> to setup
i already bought a new hard drive and we got the same message.
and i have no clue why the fan stops working, maybe the temperature is the main problem. thanks.
