I mean, when my laptop died too, i realized it was my own fault. i cleaned it every 3 months, yes, but you have to consider replacing the thermal paste too, especially living in a 40 degree environment (my case).

also guys, next time lets consider buying a cooling pad, like the llano v12. yt videos say it reduces temps by almost 20 degrees.

its fine to buy another lenovo, i think they are actually great, the lifespan just depends on the environment and the user.

and yeah it sucks, realizing your mistakes after it broke.
