hy max, why to read l14 npce68 the file is blank

Try by lowering the speedSPI to 3ms . that's solved mine. btw, leave the battery in so when you plug the adapter the laptop don't turn ON , good luck.

you should look at my posts, once I made a file for L14/15, there was an error but he managed to enter the setup and do F9. but I don't know anymore or know

Hi, can please tell us how did you exract the EC file ? and with what . thanks in advance .

[Ghost18_07]

Maxpower3 could You explain, what exactly does mean numbers above?

They are from offset when you read the EC file by a hexadecimal program like HxD . so you need to clear between those numbers.

I tried to comminicate, but RY809h don't have this chip in list of available chips. Auto dont work, so maybe resistor switch is required.

I think buying RT809H instead of SVOD was one of my biggest fault lat years.

hoaca388, tried your file and it's still not working. Now I am not able to power up the laptop. I have verified that I do have power.

If the pull up resistor is in question I would look at the NUVOTON chip specs and other programmers specs to see their requirement to perform read/write. I know there is a lot of research/homework that need to be done here unless someone here at the Badcaps.net have a solution for you.

ymifdal, I am not familiar with RT809H. If your RT809H software support NUVOTON chips, and the programmer support 1.8V and I don't see why RT809H cannot read/write. Just map the RT809H pins to keyboard pins.

rbvndonh already matched the pins I guess in post # 78
All is remaining is locating the pull up resistor to be able to test read/write

Could somebody confim this is working with Lenovo L15 gen 1 ?

Is there any way to read the EC for this model my friends using the RT809H?
