![]() I have 6050a2637901-mb-a02 with all present voltages except cpu voltage.
Fan on full speed after startup, no display ofc. This is orginal bios, any ideas? already tried lot of bios from this forum, even clear bios from hp - same result. Cpu converter replaced, same result. Resistance on CPU coil around 60-75 ohms i5-5200u. Other resistances on coils looks ok. ec reprogrammed and replaced ec winbond - same result. |

![]() Sometimes this can be solved by simply removing the CMOS battery (if it has one) for a couple of minutes, then putting it back in. Have you tried that?
