Rs.1000 is not enough (u can only buy 10 coconuts

)
so its not good to offer any money if u can not afford it.
whn powerbook starts press and hold mac key
u can use external cd drive or memory stick with mac os image
if u have the system inside press mackey+S to goto command prompt and execute below command to restart apple setup again
mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now
(same technic to remove mac password)
hope this will help
