Do we have another method? I don't have the adapter to back up the EC chip. I do have the BIOS chip programmer.

I'm still having the same error. It reaches 20V with 0.05A of consumption, but it doesn't turn on. I have the orange charging light, and the power light blinks three times. Could it be EC programming? Do you have a dump?
