Not strictly true. Older laptops could have their CMOS passwords removed
by battery removal but modern laptops store the password in EEprom
memory therefore removal of the battery will cause the laptop to lose
all it's settings, date, time, etc and maybe even prevent booting but it
will NOT clear the password.
That said, it is quite correct that there are bootable FDDs/ CDs that
will assist in password recovery/ password removal. It is also true that
physical access and time = full ownership - even if the HDD is removed
and duplicated.
