so my toshiba satellite keeps getting hot (Really hot) from a few hours of use i havent cleaned out my laptop in a few...

i've experienced something similar to this before, i fell asleep with my laptop ._. and when it fell down it bent the tip of the charger, the next day i thought nothing of it so i decided to use my laptop however when my laptop had the low battery signal i immediately plugged in the broken charger. little did i know that the charging port must have broken and possibly short circuited the motherboard. i had to get the entire motherboard replaced :I i hope my experience can help you properly diagnose the issue you are having as well ^.^
