I'm playing on a PC. I can enchant and disenchant. I have arcane blacksmith too. Smithing skill is up to 73.

When I try to recharge a magic item, I select item and "T" pops up to charge it. Not only can I not select a filled soul gem, but pressing the T key does nada.

Yes I've done a search on this forum to no avail

Please help! This is driving me nuts

Numeric keypad controls which gem is selected.
By default you should have the Black Soulgems near the top.

Is there any chance you re-mapped the "T" key? There is a known issue (unless it's been fixed; I'm not sure), where re-mapped keys continue to display the default "key hint" on-screen. I.e. it might say T for recharge, you actually re-mapped to some other key then forgot you re-mapped it?

Do you have any filled soul gems in your inventory?

Yes I do have filled soul gems in my inventory. And yes, I did assign T to another function, but changed it back to its original function. All I have are filled Greater soul gems, Grand soul gems, etc. No black ones as yet.

Hmm, wierd. Maybe there's a bug where remapping the recharge function then re-mapping it back doesn't restore it correctly? You might try renaming the .ini file for the game, and letting skyrim generate a new, default one, to see if that fixes it?

apparently Steam changes the .ini file whenever the game is loaded.

Looking further into this, the damn recharge key (T) can have a glitch and not work ::sigh::

Well I loaded the game, went into controls and hit default. AND now enchantment works!!!!

Thank you BioFringe

Mine got remapped to U, after I remapped all my keys.
