Do not give up ! :) It is true that laptop's bios security is MUCH stronger then at the normal pc. Removing the bios battery, shortcircuit or whatever woun't fix that. However it is possible to rewrite the rom memory. This can be done in a specialised service. I don't know one in your country but here in Romania some services do that. Therefore keep looking for a service, you should find them. Tell them you need your BIOS rewritten.
