Lenovo Thinkpad Ec Pwd Bypass

[volinakis]

Thank you volinakis, it works — I can enter the BIOS, but for some reason I can't save any changes. I get the same message every time. I'm only having this issue with this model. Is it possible that the EC is write-protected?

don't save anything, follow Maxpower3 steps:
Don't save with F10, just clean Pwd with Enter twice. and reset security chip. Then restart with ctrl+alt+del

Boss, the laptop finally worked!!!
I flashed the 25Q128FV rom and it finally entered the BIOS menu!
Thank you so much!
It still has blue screen when windows is starting up but I'll try to install a new one and try Lenovo Golden Key

just clean Pwd with Enter twice AND CLEAR SECURITY CHIP
or try type a new password
Then CTRL ALT DEL

Formset Main 1247C8E8... Failed to save storage. System. Status:Write Protected.

This message appears when you press F10, it's not necessary!


MEC16 33/53/63.
The timing is a bit annoying; you have to start shunt earlier.
Each EC has a different timing.

Thank you very much, volinakis and Maxpower3. I don't know, I must have had brain fog and wasn't following the Maxpower3 steps. Everything works now — thank you so much

One more problem with this Lenovo model: pressing Enter twice or entering a new password doesn't confirm that the password has been saved. After restarting the laptop, the password is still not removed.

"AND CLEAR SECURITY CHIP"

"AND CLEAR SECURITY CHIP"

I did that, but earlier there was no confirmation that the changes were saved when I pressed Enter twice

[volinakis]

what I can tell you for sure is that I didn't have problems in clearing passwords following Maxpower3 steps. And I used this method tens of times.

Which EC, ITE doesn't work sometimes.
Try Boot F12 with shunt and golden key. Delete eeprom

[Andromedus_81]

It saves when I press Enter—if I reset the CMOS jumper on the motherboard with the battery disconnected, before connecting the power adapter.

Hi everyone, and thank you for sharing such info, its very helpful ! I have 10 units Lenovo x1 carbon Extreme 2th gen (9th gen cpu), can anubody share which pins should be grounded to remove bios password ? Tried this method on T490 and worked like a charm, but cant find any info about x1 carbon extreme 2th gen. Thank you !

[moljac]

hello boss!i have lenovo l13 gen2 20vh.one request, please, does this method also work with an intel cpu? I've been trying for several days without success... thank you... it says entering setup and comes back to asking for a password again

[kicker12]

Hi!
So, strange issue here...
I got myself a very nice T490... But BIOS is (was?) locked... I THINK I have been able to delete the password: now I can enter BIOS with NO password... Anyway some parameters still greyed out: Secure boot and -for istance- reset to OS default are greyed out. All password are DISABLED... I CAN edit boot order...

i.e. SECURE BOOT is now TURN ON and, being greyed out, I cannot turn it off. I tried to Restore Factory Keys, I tried to reset BIOS to factory settings but still cannot have SECURE BOOT turned OFF. It is actually on USER MODE (for Platform mode) and STANDARD MODE (for Secure boot mode), although I cannot change these parameters. Kernel DMA protection (in virtualization) is DISABLED. Also I tried to set up a BIOS password (both supervisor and system management) BUT Sexure Boot still active and greyed out... Grrrr....

What is wrong here???

Patching bios for unlock mec1503 and mec1723
and USB2 Dongle directly unlock
Is this thing real?
Please, is there an explanation or someone to explain? Thanks

[Maxpower3]

Is this a real thing unlock via usb?
Mec1503 & Mec1723 ??????????

I think it's possible. I've already heard about a USB solution. I don't know any more.

I don't have any information for you. Sorry, but I'm interested too.


Also, stop asking me in private messages about MEC 17 or 15.
I don't know. Never done it


ETC ......

I even came to think that he knew what he was doing, that he was someone with a bit of intuition and talent. I am referring to MaxPower3.
It bothers me to know that the people who perhaps you thought that contributed good things are the ones who contribute the least. and that when they do it they only transmit useless things.
Advice, do not download file coming from Maxpower3 of you will infect your computer.
