I have a lenovo ThinkPad laptop, with 2 user accounts; Administrator and guest account. I can not login to the guest account, as I forgot the password, and when I turn on the PC, the login screen comes with the default user being the guest account, and without the option of "switch user" so that I log in to the Admin Account. Already tried restarting the PC, removing battery, but all hopeless. Trying to access the boot menu to boot from CD, it asks for a bios password which I don't know too.. Any help on how to login to the admin account, or reset the bios password?

  • When you say you removed the Battery, do you mean the external large Lithium Ion Battery or the small disc shaped internal battery? Only the latter would reset the BIOS. – Jack Oct 20 '15 at 8:55

    I would not remove the CMOS battery, cases are known where the thinkpad detects this as trying to bypass the BIOS pw, blocking the BIOS completely and rendering the laptop useless. – BramMooij Nov 20 '15 at 11:18
