Resetting a forgotten TPMpassword in BIOS(IBM / Lenovo ThinkPad)

           You have already replaced the old hard disk of your ThinkPad-notebook with a new, bigger one. You want to use the contents of the old disk in an external housing – however, that does not work.

           TPM-boards are hardware keys that ensure that the contents of a hard disk can be read only on the belonging computer. In order to remove this protection – e.g. when you want to read the disk on another computer – a password is required. Since this password is entered once and not asked again, one hardly knows when it is needed. ThinkPad owners can reset it.
            For this purpose, shut down your ThinkPad (with the old hard disk on board). Then switch it on again and press the [Esc] key untiringly – and for as long as the Windows boot-screen appears. As soon as that happens, keep the powerkey pressed, till the computer is switched off again. Then restart notebook and go to the BIOS by pressing F1.
