To unlock (turn off) Scroll Lock on a laptop, try the following methods:

• If the keyboard has a Scroll Lock (ScrLk) key, simply press it to toggle Scroll Lock off.
• On some laptops without a dedicated Scroll Lock key, use a key combination:
  • Dell laptops: press Fn + S
  • HP and Lenovo laptops: press Fn + C
  • ThinkPads: Fn + K
• If none of these options work or there is no Scroll Lock key, use the On-Screen Keyboard feature:
  1. Open the On-Screen Keyboard by pressing Windows key, then typing "On-Screen Keyboard" and selecting it from search results.
  2. On the On-Screen Keyboard, click the ScrLk key to turn off Scroll Lock.
  3. Close the On-Screen Keyboard.

These solutions let you unlock Scroll Lock on most laptops even when the key is missing or hidden behind function keys.
