Hello again, and thanks Maxpower3 for continuing to check and sending me the images for testing.
I flashed the last three images you provided in the link, and all three have the same result as always; (black screen, PC does not start, and the 2 LEDs of the "ESC" key and the "i" letter of the Thinkpad logo are permanently lit and the PC is locked without showing the boot LOGO or entering the BIOS or the errors of "CMOS" battery failure and pressing ESC or F1 or anything at all appear... Then finally I tried to flash my original image and it worked again, it shows...

Thanks Maxpower3...!!!
This time the link really works. Tomorrow I'll check the images you provided in the link and comment on the result as soon as possible so you can see it. I'd like to be able to understand all the information you sent me, and I'll read it little by little as I can to see if I can gain more knowledge. In any case, I really appreciate it if you can take the time to run tests and post them to the forum so I can test them out. You guys are really the best. People are talking about it everywhere, and I completely agree. You guys are awesome, and I personally appreciate the...Leave a comment:

Sorry, Maxpower3, but I tried to download the attached file (Desktop) that you added in the previous post, but I can't download it. When I try to download it, I get an error saying "invalid file specified." Could you check the file or see if there's a problem? Because I can't download it, but I can download the rest of the previous ones...
Thank you very much.Leave a comment:

Hello again, and thank you first of all, Maxpower3, for continuing to help me!
As soon as I get home, I'll try this last image you sent me and post the results as soon as possible.

By the way, I don't know if it's important, but when I flash my original image with a BIOS password, when I press Enter I can enter the BIOS, but I can't change anything because the supervisor password is enabled in the Password menu. One thing I didn't mention is that the option to set UEFI BIOS options and password at unattended boot is also enabled. Could this help further?
Thanks again.Leave a comment:

Thank you so much for continuing to help me here, Maxpower3.
I skimmed the PDF and the link you posted in the post, and I think it would take me months to understand all that info... hehehehe...
I'm still a newbie and I'm just learning, to be honest. That's why I don't really understand what you're showing me. I'll try to read everything little by little to see if I can figure something out. But thank you, really. Anyway, I tried the images you posted in the post, but with both flashed, I get the same problem as always: -> PC WON'T start; black screen and both LEDs lit solid as...Leave a comment:

Perfect, first of all, thank you so much for continuing to help me, Mxpower3. I really appreciate all your help.
I'll explain the entire order of work I've done and the results I've obtained. I've tried each of the images, and in this order:
1-> Yoga 11e_Password vss FF AUTO_PATCHED -> PC WON'T boot; black screen and both LEDs on solid
2-> Yoga 11e_Password vss FF + Nopwd_Patched -> PC WON'T boot; black screen and both LEDs on solid
3-> Yoga 11e_Password vss FF -> PC WON'T boot; black screen and both LEDs on solid, and 4 beeps.
4-> Yoga 11e_Password...Leave a comment:

Thanks again for your help, Maxpower3! I'm looking at the files you sent me, but I see there are 4 images. Could you tell me how to flash them or which files to flash? Is there an order I should follow? Could you please specify how I should proceed and test them? I'd appreciate it. I'm still learning from all of you, and although I'm beginning to understand some methods by reading the rules and steps in the posts, I still have to gradually learn more from you...
Thanks, Maxpower3!Leave a comment:

Thank you very much for your help, Maxpower3!!! I tried the image you provided, and the PC won't boot. It freezes (the ESC key LED and the "i" LED on the THINKPAD sticker on the bottom right of the keyboard remain permanently lit). It means a black screen, solid LEDs, and a black screen that won't boot. This is also the case when I tested the jumper between LAD0 and GND on the Nuvotron NPCE288GA0DX chip (I got the same freeze and couldn't boot the PC or enter the BIOS). I reflashed my original BIOS image, and the PC started up perfectly again, with the password back as it was at the...Leave a comment:

I've read many posts on your forum looking for information, but I haven't found a solution. I've seen that there's also an option to connect some pins of the Nuvotron ncpe288 chip to GND, shorting the LPC bus between LAD0:3 and GND, but it hasn't worked for me. I've tried it several times, using pins 1, 128, 127, 126, and GND from the LLA-1 17833-1M motherboard schematic, but I haven't been successful. I haven't been able to reset the BIOS password following the steps in the post, as the BIOS option always appears to be locked with a password. I would greatly appreciate it if any of you could...Leave a comment:

Hello again badcaps team! In the end I tried modifying the BIOS with autopatch and I managed to create the patched image of my original BIOS, then I tried erasing the original and flashing the patched image to do the password reset according to the steps you have to do in your post of the autopatch manual. Also, now I have some practice and I know how to verify the flashes well and I know when I can have a failure and correct it, and I do all the work correctly, but it turns out that my image patched with the autopath does not work (the LED of the ESC key and the LED of the letter "i"...Leave a comment:

Thanks again, I'll wait for now to see if anyone can confirm if there's a way or a BIOS patch...

That's true. Thanks again, moderator SMDflea!!
From what I've read in the forum rules post, I seem to remember that the password on these devices was stored on the Nuvotron NPCE288 chip. Is that true? If not, please correct me. If so, then I'm sorry. I'm still learning and wasn't sure. I thought the password would be in the BIOS chip: 25U128. The problem is that I don't currently have a readout of my Nuvotron NPCE288 EC chip. I need to get one to be able to read and dump it, but I still need to look into which one and where to get one. I guess there's no way to do it without the EC chip...Leave a comment:

Hello friends and colleagues! I'm here to ask if you can help me. I have a PC with a supervisor password in the BIOS, and I can't remember it. Could you fix the reading and dumping of my BIOS chip image and remove the password, or offer me a generic image if there is one that might work for my PC? I would greatly appreciate it. I've tried the autopatcher, but it didn't work for me. The information you need:
PC: Lenovo Yoga 11e 5th Generation
MTM: 20LNS0QU00
SERIAL NO.: R9115RSF
MOTHERBOARD: LLA-1 17833 - 1M 448.0DA06.001M
BIOS CHIP: 25U128 (1.8v)
Thank you very...Leave a comment:

Well, I finally got it thanks to you all. I want to thank each and every one of you; Hoaca388, lapfix, danito, and especially SMDflea, who has been very patient with me. In general, thank you all for taking the time to answer my questions and helping me. The problem I was having was a flashing error. I tried several times, but it turned out it wasn't done correctly. Finally, with one of your clean images, it worked. Thanks again to all of you, and I hope to continue learning a little more with your help. A big hug, and see you soon!Leave a comment:

Well, I waited the 30 seconds and nothing, the PC is dead, I'm starting to think that I have no solution, in addition, only the As programmer 2.1. 2 program is the only one that searching for the XMC25RH256C chip lets me do a dump and flash, I tried the Hoaca dump again and it didn't work, after doing the flashing, it decided to check the flash verification and it gave me a data verification error, but the flashing was done correctly, I'm starting to think that I don't know if the original reading I did is correct since I haven't been able to do any other readings, I don't flash with other versions...Leave a comment:

Hi Lapfix, first of all, thank you very much for your help!
I've performed both the BIOS reading and flashing without a charger connected, without the CMOS battery connected, without a battery, and
even with and without RAM installed. I've tried multiple methods, and the same thing happened every time. I press the power button.
The button lights up for a couple of seconds, then it turns off and won't boot. I've also tried the dump Hoaca provided me in post #36 again, as you mentioned. I even tried the dump you provided me again just in case.
It might have flashed incorrectly...Leave a comment:

Please can someone help me? I have a black screen, the PC does not start, does not boot, does not enter the BIOS, and it does not work even when I flash my original dump again, it is something that I do not understand because both my CH341a programmer and the As Programmer and the connection cable between both work correctly, the problem I had when flashing the image that the user lapfix provided me, from flashing that image, I have a black screen, even when flashing my original dump, please help 1, my PC has died, please!Leave a comment:
