Hi, I am looking for the schematic of this HP ENVY Laptop 17-cg1008ca Motherboard GPT70 LA-J504P or this component, PQB4 reference (Unable to read the text beyond P5) I also want to replace these two other parts on the same board, one labelled 43t (if I am not reading it wrong) and another resistor labelled 2R0. Furthermore, if someone with experience could tell me, why would this component burn in order to avoid this happening again? And I have a question about modding this mobo in order to have more VRAM, right now, it has two of this chip Model: H5GC8H24AJR-R2C Brand: Hynix Series:GDDR5 Capacity:8Gb Voltage:1.5V Which equivalent to 2 GBytes and I want to replace them to get 4 GBytes (to make some AI models work on it). Thank you. |

Burning 43t and 2R0 is most likely overcurrent. Three legs of 43t connected, so maybe a source. Maybe two different voltages through those two equal resistors. 9538 seems to be a battery charger. |

intersil datasheet may help if you don't get the mobo schematics |
