Precaution before updating bios
Here I’m going to post some laptop screen photos showing bad video output.
I’ll explain what was wrong with the screen and how I fixed it.
This article describes a common overheating laptop scenario along with a fix that works.
Overheating laptop and related shutdown problems are very common in notebook computers, especially in home use.
A common example of this buildup of material is shown in the image to the left.
If the heatsink grill is sufficiently blocked, the fan will be spinning at maximum speed and it will no longer be possible to reduce, or even stabilse, the internal temperature of the laptop.There were a lot of vertical lines, and they were changing color without any pattern.To me it looked like Northern Lights (never seen in real life) :). As soon as I applied some tension to the screen it changed the pattern.The effect of this is to block some of the airflow over the heatsink grill.With less physical space for the air to get through, the air is not picking up heat from the whole set of fins.
