Re: Yoga Slim 7 Pro-14ACH5 D - Type 82NJ
One more thing:
USB-C is responsive to power, but no signal (hence no post)
Regular USB: such as keyboard are not indicating as it was plugged in, like caps lock light ....no caps lock light in external keyboard; hence no post.
Any suggestions?Leave a comment:

Yoga Slim 7 Pro-14ACH5 D - Type 82NJ
Anyone have an idea why no display? Probably no post too (Firstly)??
Is this a known issue?
The laptop is new; took new bios from Lenovo website swap DMI and cut off cap.
It seems it has not got to read the bios yet hence not posting.
Laptop turns on, fans are spinning, USB-C is responsive....

Re: ThinkPad L13 YOGA
Maybe it is not possible...I need to read more....because I do not think there is a direct access vis the SPI chip. The access to EC is starting in the next boot ( after flash)....hence might not be usable directly.Leave a comment:

Re: ThinkPad L13 YOGA
In fact the segger pinout header is a TYPICAL JTAG HEADER....So maybe mapping the JTAG header to the spi and using jtag software might be a solution.
Any thoughts?Leave a comment:

Re: ThinkPad L13 YOGA
Well here where it gets interesting.
You post the EC chip map, which is great, however if the plan is to connect through the SPI Bios chip ( hence 25q128.....) I actually think the map of this chip, which is known in any data base (Winbond or even mouser etc for example). Now in my case to map it to Segger 20 pin out header as published above.
Am I correct?...Leave a comment:

Re: ThinkPad L13 YOGA
Nice!
So my first hurdle is to find the correct pinout from the clip header to the Segger J-link plus headers....how to map it correctly.
I found this one...but i guess will need more accurate links and how to.

If someone knows how to map this correctly will be appreciated.Re: ThinkPad L13 YOGA<br /> <br /> ...nd the correct...Leave a comment:

Re: ThinkPad L13 YOGA
I believe you are referring to Jtag. Ideally Vertyanov Programmer.
I only have J-link plus segger, ulink2 armkeil, ulink2 keil and arm link plus.
Will it be possible to use Jtag via the bios chip instead of the keyboard line?
I think it is possible. If it is I am thinking of using the clip of the cheap usb programmer and its 8 pin header and try to connect this to the pins of the Jlink plus pinout.....Any idea if possible?...Leave a comment:

Re: ThinkPad L13 YOGA
So far I have tried another dump from an unlock L13 Yoga Intel 10th Gen I have as well....Just to see if there will be any response from the laptop....Nothing.
It seems npce288 chip needs to be reprogrammed.
The reason leads me to this conclusion is the fact that after writing the "unlock bios" offered to me ( as mentioned above) the last stage was writing to EC...shut down and re program the original bios.....My conclusion that writing to EC messed the npce288 chip.
Does anyone have an idea? a good one based...Leave a comment:

Re: ThinkPad L13 YOGA
The regular usb one from eBay....I have used this programmer many times before.
after each read/write I always do full verification from the programming/writing the "offered" bios all is good and is not questionable.Leave a comment:

Re: ThinkPad L13 YOGA
Hello,
Following your private message and to this reply made by you: stating your solution to unlock will work AND WILL NOT BRICK THE MACHINE AFTER I HAVE CARFULLY RAISED THIS POSSIBILTY AS VALID....
YOU WERE WRONG ....NOW THIS L13 IS BRICKED NO RESPONSE DEAD...THANKS VERY MUCH...Last edited by piernov; 06-18-2022, 05:31 AM.Leave a comment:

Re: ThinkPad L13 YOGA
Hi,
Thanks for your quick post. I started reading more and realized that this L13 Yoga has NPCE288 chip. From what I have read it see that only with JTAG possible to unlock. Is this correct?
I don't mind trying your patch but I am concern about not able to use windows if not successful. I read that if patch is not working it might mess with the "allowed" number of password tries and will lock the laptop.
Is this correct? Or reverting back to the original dump should be fine?
Thanks in adv...Leave a comment:
