Hello!, on this model bios had password, did both 32mb and 16mb bios and now there is no password. but laptop starts only after 30-40 sec with error security Device problem (There is a problem with the Security Device on the unit.) Tried to update to the newest bios after boot to windows, but still same. Any ideas?, thank you!
