Some keys aren't responding on the gaming laptop.
My laptop (MSI Stealth GS75 10SE MS-17G3) was experiencing frequent high-temperature CPU crashes. I chose to open it up and reapply the thermal paste. Once reassembled and powered back on, I noticed several keys were malfunctioning—some LEDs lit but typing didn’t register properly. After several attempts to reattach the keyboard ribbon cable, all keys functioned correctly. A few days later, some keys stopped working entirely. I brought it to a local PC repair shop for evaluation. The technician suggested the issue was likely software-related but insisted on a diagnosis before proceeding. After installing Ubuntu, the keyboard issue persisted, indicating a hardware problem.
I searched online for replacement parts and found a keyboard online for around $70 to $80. It seemed reasonable, though I lacked detailed instructions on resealing a keyboard or understanding the process’s complexity. None of my nearby repair services were willing to reseal keyboards but offered to replace the entire bottom shell. I couldn’t locate an exact shell for my model, but I suspect a lower-spec shell would fit, costing approximately $500.
I’m trying to decide whether I should try resealing the keyboard myself for about $70 or proceed with replacing the shell entirely, which would cost around $700 plus repair.
repairing a faulty laptop keyboard follows a clear, easy-to-follow procedure using basic tools and some technical skills.
if you’re familiar with the process or know where to look, i consider it an enjoyable challenge.
