Oh, misread, He needs to open the menu and press the key to charge. If that dosen't work, it's a bug.

There are work arounds, though, like fortify destruction 100%.

Or you may have to clear your cache and start a new game.

Lastly, your enchantment magnitude might be so high to the extent that it cannot be used, but the weapon is still full, like if you did a fortify resto loop to make enchanting pots that you used to make the enchants.

Finally there are weapons with enchantments that don't need charging, like the ones on Ghostblade, Enhanced dwemer crossbow, Wuthraad etc.
