iPads are a line of tablets made by Apple Inc.
iPad 1 (2010) not powering on:Edit
The battery has been deeply discharged and has to be replaced. There are techniques that may work, but do these at your own risk. I personally tried this and it fixed my two dead iPads. https://youtu.be/2QVFJIqD5Yw
Apple Pencil (G1/G2)Edit
|Not charging||G1: try connecting your Apple Pencil to the lightning charging adapter and charge the pencil for a few hours. Make sure that the charger and cable are preferably original or MFI certified and known working
G2: try multiple iPads to see if the issue persists. If it does, your only option is probably to replace the entire Pencil. Unfortunately these are not at all meant to be repaired and there are no resources available.
|Not writing||Check if your pencil tip is working correctly! I have personally seen many pencils that work perfectly, but just need a new 3$ tip. These tips are consumables that wear over time and eventually break. Luckily they are one of the only Apple products easily repairable. To change your tip, simply get yourself a set of replacements from the Apple Store, eBay or Amazon and follow these instructions: https://youtu.be/fo9CCDByXF8
The tip isn’t completely made of rubber. There is a tiny gold pin inside the tip that is necessary for the writing to be recognized. Sometimes this breaks. You may have removed it improperly or dropped it. Or dirt could be preventing a connection.
|Connection issues||Make sure your iPad working fine with other Bluetooth accessories. Updating it is also a good idea. Try the basics like reboots, restoring, etc. If you have determined that your actual Pencil is faulty, your only option unfortunately is to replace the entire Pencil.|
