Chosen Solution
I want to reset the BIOS password of my machine. Reading a Lenovo support guide[1] they say: """
- Turn off the computer.
- Remove the battery pack.
- Remove the backup battery. For instructions on how to remove the backup battery, click here.[2]
- Turn on the computer and wait until the POST ends.
- After the POST ends, the password prompt does not appear.
- The POP has been removed.
- Reinstall the backup battery and the battery pack. "" Step 3 mention a backup battery. I suppose it is the CMOS battery. In that case: What are the steps required to only remove this battery? If that’s not the case: What is it and how to remove it? [1] https://support.lenovo.com/ve/en/documen… [2] https://support.lenovo.com/ve/en/product…
Hi, Here is a link to the service manual for your laptop. On p.73 subject 1070 Backup Battery, it details the procedures necessary to remove the backup battery. https://download.lenovo.com/ibmdl/pub/pc… Hopefully this is of some help
