Will Only Boot Up After Battery Has Been Unplugged For Extended Period Macbook Air 13 Early 2015

Chosen Solution

No light on charger, will not power on. Unplug battery, use charger only: no power. Unplug battery for extended period, plug back in, charger works and computer comes on… most of the time. Will work for several hours then just power off and won’t come back on until I unplug battery as above. I have cleaned around Power key, I/O board assembly and power socket. No change. Now I am running only on battery to run down the charge to almost zero, will recharge and run down again to calibrate battery to remove it from the list of suspects. Customer says no spill. Inside looks pristine, no water marks activated and no corrosion visible with my Dollar store magnifying glass
