I bought a Patriot 16GB DDR5-5600 SODIMM for my Lenovo LOQ 15AHP10, but it failed to work in both my laptop and a friend's laptop. The system powers on with fans and lighting, but it will not reach the BIOS whenever this module is installed. I tested both slots, tried the module by itself, reseated it repeatedly, cleaned the contacts with an eraser and isopropyl alcohol, and compared its behavior with working memory. The module warms up normally, but that is the only sign of activity. The seller issued a full refund and told me to dispose of it, so I still have the stick and am wondering whether there is any safe or worthwhile way to revive it. I'm willing to experiment, even if the chances of success are low.

Check the Patriot warranty and contact the manufacturer if you want a final diagnosis or replacement. Be upfront that the original purchase was refunded; do not try to claim a second reimbursement. Since the module fails in two different laptops and the basic troubleshooting has already been done, an official replacement is the only realistic route.
If the laptop cannot POST with the module installed, even after testing it alone in every slot, it is very likely electrically defective. Heat, fans, or RGB only show that some power rails are active; they do not mean the memory chips or controller are functioning. There is no practical consumer repair for a failed SODIMM, and opening or modifying it is more likely to make it permanently worse than restore it.
The DDR5 module may use on-die ECC internally, but that is not the same as requiring an ECC-compatible laptop. A normal laptop should still be able to use it, so ECC compatibility probably is not the cause.
It is worth checking the warranty, but I would avoid risky repairs unless the manufacturer specifically offers a diagnostic process. SODIMMs generally cannot be repaired with cleaning, firmware changes, or software tools when they prevent POST.
