Periodically, we had better bring out each laptop (also spectacles) to use for a while. This sentence is vague until I point out 1) oxidation and 2) longRest->recovery.

More than one laptop has shown “longRest->recovery”.
I had to power down for many days to get a few hours (or longer) recovery from a defect.

This pattern has many implications.

A slightly defective laptop (eg: A299) can be used in place of a new laptop to prolong the latter’s shelf life.
