Questions about this item

How much heat or noise does the 45 W 20 V adapter produce when it runs continuously?

The unit has no fan and no moving parts, so it is silent; warmth is normal for a 45 W brick under load.

What must I already have for this charger to work with my Lenovo?

Your laptop needs a 4.0 × 1.7 mm charging port and must accept 20 V 2.25 A input; the adapter includes the mains cord.

Will this 45 W supply safely run my older IdeaPad 310 that originally used a 45 W brick?

Yes — it matches the 20 V 2.25 A 45 W rating and the 4.0 × 1.7 mm tip used by the 310 series.
