First Aid:

• Shut it down! Give your laptop a breather. Unplug it, remove the battery (if possible), and let it cool completely.
• Clear the vents! Dust buildup is a major culprit. Use compressed air or a soft brush to clean out the vents on the sides and bottom.
• Check for blockages. Is your laptop cozying up to blankets or pillows? Give it some breathing room on a hard, flat surface.

Preventative Measures:

• Software savvy: Update your drivers and BIOS. Disable unnecessary startup programs and adjust power settings for lower performance when on battery.
• Fan fiction: Listen to your fan! If it's constantly whirring or making strange noises, get it checked. Consider adjusting fan settings in the BIOS for more aggressive cooling.
• Cool it down!: Invest in a laptop cooling pad for extra airflow. Work in a well-ventilated room, and avoid using your laptop on soft surfaces that block vents.

Bonus Tips:

• Less is more: Close unused tabs and programs to reduce CPU strain.
• Undercover agent: If dust persists, consider opening the back panel (carefully!) for a deeper clean.
• Pro help: For persistent issues, seek professional repair. They can diagnose hardware problems and replace thermal paste (the goo between CPU and heatsink) if needed.

Remember, prevention is key! By keeping your laptop clean, cool, and optimized, you can avoid overheating woes and keep your work flowing smoothly.
