4. Operating Instructions

This replacement keyboard functions identically to the original keyboard it replaces. It features a standard QWERTY layout, a pointing stick, and backlighting for improved visibility in low-light conditions.

• Standard Typing: Use the keys as you would any standard keyboard.
• Function Keys (Fn): The 'Fn' key, typically located in the bottom-left corner, can be used in combination with the F1-F12 keys to access special functions such as volume control, screen brightness, external display toggling, and keyboard backlight control. Refer to your laptop's user manual for specific Fn key combinations.
• Pointing Stick: The pointing stick (TrackPoint) located between the G, H, and B keys allows for precise cursor control. Use the associated mouse buttons below the spacebar for left and right clicks.
• Backlight Control: If your laptop supports it, the keyboard backlight can typically be toggled or adjusted using an Fn key combination (e.g., Fn + F10 or Fn + Right Arrow).

5. Maintenance

Proper maintenance can extend the life of your keyboard and ensure optimal performance.

• Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps. For dust and debris between keys, use compressed air. Avoid spraying liquids directly onto the keyboard.
• Spills: In case of a liquid spill, immediately power off the laptop, disconnect the power, remove the battery, and turn the laptop upside down to drain the liquid. Do not attempt to use the laptop until it is completely dry. Professional inspection is recommended after a significant spill.
• Avoid Force: Do not apply excessive force to the keys or the pointing stick.
