Re: HP CQ45 convert descrete to uma

Not possible to convert on this mb. Read page2 of schematic. LVDS grows from MCH and it is not possible to re-route it. So you need to replace the graphics chip. However, its very difficult to get a chip which is genuine.

Arrow on page 2 seems to be a mistake, LVDS signals are routed directly from GPU not MCH according to pages 19/20. If it was routed from MCH there could be a conversion possible. Here I confirm it's not possible. (MCH is P-series so it doesn't even have a GPU anyway)

This GPU shouldn't have a high failure rate (these have the "good" white underfill, as opposed to the previous series), see-ic has some refurbished G98-700-U2 (if that's what on this board), could be good enough.

Better to just replace the board at this point, you could buy the iGPU only variant LA-4101P if you prefer.
