If I use my laptop on bed when i do light task like office etc. In these scenario temps are near 45-55C. But at this temp my fan dont kicks. My fan starts to work mostly after temp 60-65C. The back side of my laptop is fully covered (i.e no vent ) except for fan (which is a very little opening). So there is no passage for air to go inside and cooldown motherboard components. I have also tested that using it on the bed and on a hard surface with light usage has a negligible effect on temps(aprox 1 to 3C only). So is it ok if i use my laptop on the bed????
