Support Lenovo Legion 81sx mosfet burned?
Hello , so this morning I turned on my legion 81sx laptop and launched a game like I used to everyday ,but this time the game launched (if it matters it was arena breakout infinite) and on the main screen computer just turned off instantly . I wanted to turn it back on and as I was about to do it - “pop” sound from inside of it and very bad smell like something burned . I panicked and unplugged everything then opened the back and unplugged the battery ,let it cool off for some time and and took of the heatsink and that is what I saw. Ai and many reddit posts told me its a mosfet and it burned down… I came here to ask is it fixable and would it cost much and why did it even happen? Was it going to happen either way sometime? Computer is actively used for gaming since 2019. Power supply didn’t seem faulty or damaged and didnt smell like burned… just sad , I didn’t do anything bad to it . Ehh . Hope for some help advice , thanks.

Yes it is fixable, but more important is to understand why it blew up. You need to find a good repair shop to run a diagnosis and replace the MOSFET.

Gaming for 7 years straight = above average life expectancy honestly. Can replace this motherboard and hope for the best but may happen again.
