Lenovo ThinkPad E15 Gen 3 Running Slow

A nearly full drive can significantly reduce system speed.

• Check Available Storage: Go to File Explorer (⊞ win + "file explorer") -> This PC and check the available space on the "C: drive". If it’s near full (under ~5% free), clear unnecessary files or uninstall unused programs.
  • You may want to also consider upgrading your storage if you are running low on space. [ADD LINK HERE]
• Run Disk Cleanup: Search for “Disk Cleanup” in the Start Menu (⊞ win) and run it on the primary drive. Select temporary files, system cache, and Recycle Bin items to delete.

System or driver updates may be missing, affecting performance.

• Run Windows Update: Go to Settings -> Windows Update and install all available updates.
• Update Drivers: Visit Lenovo Support and enter your device model (E15 Gen 3 Laptop (ThinkPad)) to find and install the latest drivers.

If your RAM (Random Access Memory) is nearly maxed out during use, the system may lag.

• Check RAM Usage: Open Task Manager (CTRL + SHIFT + ESC) and go to Performance -> Memory Tab. If usage is consistently over 80%, consider upgrading the RAM [ADD LINK HERE]

As the device runs, it stores temporary files and assigns system resources for various tasks.

• Restart Device: Restart your device (⊞ win + X, then press U, then R) so it can clear temporary files and reset assigned resources.

Excess heat can slow device performance.

• Check Vents and Fans: Turn off the device and inspect the vents. If they are dusty, use compressed air to clean them and remove any blockages.
• Internal Cleaning: Remove the back panel of the device and gently clean the fan area. Ensure fans spin freely and are not obstructed.
