Pencil

The Pencil is a completely sealed off unit.

To be able to get inside to replace that very teeny, tiny little rechargabke battery inside of an Pencol, means actually destroying the Pencil to get inside of it.

That is why.

Sorry.

You cannot store Pencils for any prolonged period of time and NOT keep them charged up to some level.

If your Pencil/s sat around unused or unopened and not kept charged up for more than a few weeks, or so, OR

EVEN LONGER, then the battery in your Pencil may have failed and is dead and you will have to purchase another

brand new Pencil or get, if still under warranty, a free replacement Pencil from Apple.

Sorry.

And it looks like some things about the Pencil have NOT changed in the new version 2 model, either.

FYI and something Apple will never, EVER divulge to it potential iPad Pro/Pencil customers/users unless the potential customer/user is smart enough to ask about,

Due to the “always on and active/standby” nature of the Pencil and, also, due to its very tiny rechargeable Li-

ion battery ( smaller than the eraser head on a REAL wooden pencil ), the Pencil needs to be constantly charged up to some significant charge level ALL THE TIME, even when not using the Pencil for prolonged periods of time.

The Pencil needs to be kept charged to a minimum of 5-10% all the time.

If the Pencil battery is allowed to drain down to 0% and allowed to stay in that flat condition for more than a few weeks, or so, OR EVEN LONGER, that very tiny little Li-ion battery is too small to keep at a 0% state for a long period of time and it will fail and the Pencil will be dead and you may have to “pop” for another $99/$129 Pencil, once again!

Apple only has a one-year warranty on any Apple accessory items.

You need to keep your Pencil charged all the time, even if it is only to 10%-15% charge. It must keep some charge level in that tiny Lithium-ion battery at all times!

One last ditch thing you can try is to plug the Pencil's Lightning connector into the iPad.

Then, try a simple hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

See if the Pencil starts charging then, when it reaches a sufficient charge, like over 15%, or so, or more, disconnect the Pencil and reconnect it to see if it Bluetooth pairs.

If it does pair, try using it.

Someone else posted another possible idea/solution that you can try before completely giving up on your Pencil.

Try heating up your Pencil using a hair dryer on its highest setting for 5-15 minutes, or so.

Do not get the hair dryer heat too close to the Pencil.

Or try leaving it near an active home heating register, where you live, for 10-15 minutes, or so.

See if this will revive the Pencil battery, or not.

If still no joy, your Pencil is definitely dead.

If out of warranty, you will need to purchase another Pencil on your own.

Sorry and Best of Luck to You!
