there is no cure for BIOS locks. (by lenovo design rule #1)
that way data can not be stolen.
if you ask this is lenovo web support site they will answer you.
and is asked there 10,000 times, and the answer never changes.
even worse is bit-locker locked and with matching SED self encrptyed drives. (100% locked down LT) that business owners love. for a fact.
used laptop 101: "LT"
what you just did is 100% dead wrong. (now bios settings lost)
shorting any EEPROM is evil to the max is that Reddit lies ?
the only safe way is erase the HDD/SSD boot drive, ,heck all drives.
then reload the unstated OS to the LT.
if this is windows, well microsoft.com has the OS reset steps.
billions read this page ever day at MS ? factory OS reset
then there is answer 3.,
the Lenovo has a book as all LT have and the chapter covering this topic
OS recovery.
some LT have Install image on the HDD that reloads the unstated OS from scratch.
some say its and option in their book and is true. only looking finds that.
I guess you meant that BIOS ADMIN PASSWORDS ARE SET.
AND BIOS IS NOW DEAD FOREVER.(PAGES)
WHY NOT ASK THE MAKER FOR HELP FIRST AND NOT DO HACKING AS STEP 1.??????

I must worn you, many PC makers web sites forbid and delete all posts
with BIOS Password hacks. of any kind,. by laws too in many countries.
if the owner locked it , the only cure is ask the owner to unlock it.
or tell the broker you want your money back.
ADMIN locks are serious business now.
this hacked only worked back in the early days of LT, say some 20 year old Toshiba, with the hidden mobo jumper that did infact reset it all
desktops still have the jumpers, but not LT.
your LT is 2009 made? has DVD drive so is old.
Intel Core 2 Duo P8400 CPU at 2.26 GHz<< no good for w10/11
Q3 -2008 CPU.
old. and slow.
if it must be hacked just google forever, and even blow up chips
hot wiring them in bogus ways. RIP now double dead PC>
