What is the average battery life?

Why is my laptop overheating and shutting down?
Overheating can be caused by blocked vents or a dusty fan. Clean the vents with compressed air and ensure the laptop is on a hard surface. If it persists, consider updating BIOS and checking fan operation.
How do I update the graphics driver?
