Modern laptops use lithium-ion batteries, so keeping them plugged in at 100% won’t damage them instantly.
Once they’re full, charging stops and the laptop runs on the adapter.
The real issue is leaving a lithium battery at 100% for long hours, especially with heat.
Over time, that slowly reduces battery health.
Simple fix: if you’re mostly plugged in, set a charge limit around 80% or unplug once in a while. If you’re always on the move, you are good to go. No issue
