Asus G751J M.2 modifier option
I just received an Asus G751J from a seller who didn’t include photos. It seems the touchpad IC failed, overheating heavily and preventing the laptop from starting. Before purchasing, I noticed the model had an M.2 connector, but when I opened it, those pads were missing—likely due to cost-cutting. I’m curious if it’s feasible to buy a replacement connector and solder it in place. From what I compared with high-res images of similar boards, the IC and capacitors look identical except for the presence or absence of the connector. Would that work? Would a BIOS update be necessary?
It could take more than expected. The connector is inexpensive, but you’ll also need an SMD heat gun, flux, and solder. I’m not sure if traces will be available. In any case, I wouldn’t bother with this.
I have everything at my workplace. The traces shouldn't cause issues; it seems since the SMDs are present, they likely didn’t create an entirely new motherboard without traces, but simply omitted the M.2 connector. Most users won’t attempt to solder an M.2 slot here, so building a new motherboard without traces probably wouldn’t add unnecessary expense. The question is, what type of M.2 connector exists on AliExpress, considering there are several 4+5 models with varying heights?
Updating this subject for those searching: The smallest height 4+5 M.2 connector likely fits a 2.3mm size. All traces are present, just solder it in place. Issue with SATA M.2 SSDs not being detected; you can adjust the BIOS and switch to NVMe SSDs. Refer to this guide: https://rog.asus.com/forum/showthread.ph...ep-by-Step. It advises using the 211 BIOS, though you've faced problems. If successful, flash it and the NVMe will appear during Windows installation. You can also try a standard SATA SSD on the SATA port, but it must be a compact one and removed from its case.
