Why is my Chromebook getting hot and making noise?
From one day to the next, it began to make a lot of noise and started getting really hot after a little while of using it. What should I do?
More than likely your issue is the fan. Over time fans can become dysfunctional due to dust buildup. You should follow the fan guide listed on this site at HP Chromebook 14-Q010DX Fan Replacement to remove the fan and clean it. If this doesn't fix your problem you should consider replacing your fan with a new one.
This could happen for A number of reasons. The 2 most common are “no air flow” on the bottom when in use. Make sure when you use your Chromebook, you have good “air flow” under it, on a hard flat surface is the best. Don't keep it sitting on A pillow, mattress, blankets, ect. this blocks the air flow under the Chromebook. The 2nd reason, A bad fan. All Chromebooks don't have fans, but for the books that do, fans get full of dust, loose exc. over time. Also checking the bottom of the Chromebook making sure the wholes are not full of dust is a good start.
