please you need to reset its bios. open the screws behind your laptop with keyboard icons to access your laptop cimos battery with care remove it for some time(3min), power on your laptop until it boots up. turn it off and put the battery back. the password will removed.
Both errors are related to the backup battery which is located under
the main battery. It is probably dead. You can get one on
eBay for $3.29 w/free shipping or pay a shop $20 to put one
in. If you do it yourself be very gentle plugging it into the
tricky little slot - it is possible to break the connector loose from
the motherboard but it is an easy repair if you have patience and
dexterity. As for the password, try just hitting enter. It
is the supervisor password to change the BIOS settings and was probably
Hope this helps.
you may need a bios update. if a password has been set for the BIOS then you need to use it in order to do the update. BIOS updates are usually available from HP website and depend on the model of your laptop.
Some of the older thinkpad had a program you from the OS or a boot floppy to had to run to get change the bios settings. But the BIOS key on most is F1. So if you press that key as soon as you turn the machine on and anything appears on the screen, and once you've provided the password you can then change the password to blank within the bios.
If you don't know the password at all, there may still be a way to reset it, but it may require a call to IBM/Lenov, or some other tedious process.
