OK. Update! Did the 20KΩ. And it worked perfect on a ProB 6475B as well! ....Again.... Thanks Team!

Ding Ding! It works, Thank you so much!! (Isn't it crazy? A post from 10 years ago is still helping people today) Thanks to the author and the "Internets" sic. (a little dig at "Dub-ya")

Hi!sorry for bringing up an old post. But my HP 6450B is having the same problem right now. However, my motherboard is different compared to the one in this post. From all of the information here. i believe i could make it run by boosting the middle pin to 6-7 volt. Can i just simply run a resistor from 19v (red) to the 2.4v pin (blue). Can i do it this way since the motherboard is different despite being the same model
