HP 15/84K04EA does this laptop model have a smart charging feature? Can I leave it plugged in all the time? Thank you .
Your HP laptop is a 2023 model and all modern HP laptops have the HP Adaptive Battery Optimizer technology built in, that is HP's version of Smart Charging, so with that and the Windows technology, you can safely leave that laptop model permanently connected to the mains electricity supply.
AI answer
Windows includes a Smart charging feature, but whether it is available and how it behaves on a specific HP 15/84K04EA device is determined by HP, not by Windows itself.
Smart charging is implemented differently by each device manufacturer and model. To check if this HP laptop supports it and how it works (including whether it is safe or recommended to leave it plugged in all the time), the device manufacturer’s documentation or support site must be consulted.
On devices where Smart charging is enabled, Windows may intentionally stop charging below 100% and show a heart icon on the battery indicator, with status such as “Fully Smart charged.” This behavior is designed to protect the battery when the device is plugged in for long periods.
For Surface devices specifically, Smart charging is always active and may limit charge to about 80% when plugged in for prolonged periods or at higher temperatures; it can be paused when a full charge is needed. Other manufacturers may offer similar or different controls.
