Your laptop may be running slow due to too many background programs, insufficient RAM, or malware. Try closing unnecessary programs, upgrading your RAM, and running a full antivirus scan to improve performance.

Reduce screen brightness, close unused applications, disable Bluetooth and Wi-Fi when not in use, and use battery saver mode to extend battery life. Also, consider adjusting power settings to optimize performance.
Turn off your laptop and disconnect any power sources. Use a can of compressed air to blow away debris, and gently wipe the keys with a slightly damp microfiber cloth. Avoid using excessive moisture.
