[SOLVED] HP G72 Laptop dead gpu fix by switching to cpu graphics?

[george9494]

Hi, i have a G72 hp laptop with a dead gpu chip and a black screen of death. I had the gpu chip reflowed successfully a couple of months ago and now it is dead again cause it is temporary fix anyway. I've researched the internet for alternative fixes and i stumbled across on a video from youtube in which the problem is solved by removing the gpu voltage regulator from the motherboard and instead, using the cpu's intel hd graphics (if it has). So my question is, has anyone done it and worked or are there any other possible fixes to switch to cpu graphics without removing gpu voltage regulator?

Yeah done it many times, what is the exact model? You cant obviously do much gaming anymore on the laptop since its older intel hd graphics but its fine for other use.

Yes i dont want to game just basic use. G72-120ev is the exact model and the cpu is an i3-330m which according to intel it has intergraded graphics.
Also, is this dark grey rectangular thing the voltage regulator which i need to remove? (see red arrow)

Your absolutely sure its exactly this motherboard shown on that picture? Double check it reads DA0AX1MB6F1 REV:F like on that pic on your motherboard

Yes, this is what it reads

Does it say PL11 on the motherboard near the coil ?

Not sure, cause I've taken this photo back when i disassembled my laptop.

Dont have schematics but this is model without discrete gpu : https://witcomputers.com/product/hp...oard-rpga-989-socket-da0ax3mb6c1-da0ax1mb6h1/

Looks like it doesnt have the coil, you can try removing it, some models need way more work than just that. Theres nothing to lose if your literally reflowing the gpu chip at this point

Ok, i will try this and i will check if it says pl11 too. What you mean by some models need way more work?

Might not automatically switch to integrated like magic, some models you need to literally desolder whole gpu chip. Try to find schematics for the exact model and you can pm me them if you find.

Actually, dear lord this one is a bit harder, i mean its easy for some laptops it works after removing component or two, or just even the coil, but not in every case
