After boot, your shield power should once more be visible from console info.
Keep in mind that your shields only run at 20% power until you are actually in
combat. Also, ramming attacks are totally unaffected by your shields.
Shields regenerate 5% every battle tick, and have a diminishing returns on
their ability to absorb damage. In particular, even a shield which has been
totally decimated by mage blasts and cannonball strikes will still regen back
to full within a minute.
