Ensure that the laptop vents are not blocked. Clean the vents with compressed air to remove dust. Consider using a cooling pad and check for any BIOS updates that may address thermal management.

Reduce screen brightness, close unnecessary applications, and disable Bluetooth and Wi-Fi when not in use. Utilize the power saving mode and check for BIOS or driver updates that may improve battery performance.
Run a virus/malware scan to ensure the system is clean. Use the Task Manager to identify and close resource-heavy applications. Consider upgrading the RAM or switching to an SSD for better performance.
Visit the Dell Support website and enter your laptop's service tag. Download the latest drivers and follow the installation instructions. Use Dell's SupportAssist for automated driver updates.
