LA-K862P UMA conversion

[orientalsniper]

Hello guys, I got this LA-K862P motherboard, it has a shorted GPU core and memory chips, I've already desoldered the memory chips, do I need to desolder the GPU for an UMA conversion?


I've done the following:

• Moved RH44 resistor to RH43 (uma resistor switch)
• Removed PLW1 and PLW2 (gpu power)
• Removed PLV2, PLV3, PLV4, PLV13

I'm supposed to have 19v in PLB1 (+19V_CHG) but there's a leakage and I'm getting ~3v.

remove prv74 only

Conversion was successful by removing PRV74 and GPU, I'm not sure which one helped.
