Overview

• Most failures trace to low charge, a loose tip, Bluetooth or software glitches, compatibility gaps, or physical damage.
• Start with a 10‑minute charge, toggle Bluetooth, forget and re‑pair the Pencil, and try a force restart of the iPad.
• Confirm the tip is snug with a paper‑thin gap, test in Apple’s Notes app, and try the Pencil on another iPad to isolate the fault.
• Follow model‑specific charging: first‑gen via Lightning under the cap, second‑gen and Pro on the magnetic edge, and USB‑C model via its sliding‑cap port.
• Escalate when you see impact damage or persistent anomalies, noting that internal transducer damage requires replacement, and beware third‑party chargers or non‑Apple screen repairs that can mimic failures; for stubborn pairing, remove bulky cases, consider resetting network settings, or use the LightBlue workaround reported for some 10th‑gen iPad and first‑gen Pencil pairings.
