Could anyone help me with a ThinkPad, which is currently password in the BIOS?
thinkpad x1 extreme gen 1
model : 20MF-000DUS
bios : N2EET42W (1.24)
s/n : R9-0V246W
year : 19/05

note : I already tried with Lenovo Patches v2 and it left my laptop with a black screen and beeps as if it was missing memory ram.

Off topic, this thread is for the T480.

Hello. I'd like some help with a t480 with a (presumably) corrupt bios.
Type: 20L6-S18E00
S/N: PF-1FD5RP

The device doesn't boot and gives a chime, error code 010288.
Due to this, I don't know about the bios revision information.
Dump of the chip is attached.
Thanks in advance for the help!

As someone said before, this isn't the most active thread.
I understand that, but I'd also really appreciate a pointer or two.
As things are now, I have no idea how to go about things.
Thanks in advance yall.

Boots fine, but seems like the bios is locked.
I get the message 'Bad CRC of Security Setting in EFI variable' and then i meet with a locked bios.
Should I try the auto patcher now?
Thank you so much for your help, if you have any more advice I would sincerely appreciate it.

Yes, of course you can try the autopatcher.
Then you can Load Defaults (F9) and maybe the error will disappear.
If not you probably need to rewrite your DMI info with Lenovo U1 or Golden key this will rewrite your CRC. There is plenty of info about dowload and usage here :

Okay. I will keep this in mind.
Running autopatcher leads to the same jingle as before, so I will probably make a post in that thread.
Thank you so much for your help.
