Samsung Galaxy Book 6 Pro Battery Not Charging Fix in Hyderabad

“Battery not charging” on the Samsung Galaxy Book 6 Pro is distinct from “charger not working”: the adapter is alive, the laptop runs on AC, but the battery percentage stays frozen or drops. Samsung Settings includes a Battery Protection mode that caps charging at 85 % — widely enabled and often forgotten, it accounts for 30 % of our calls. Hardware causes include a failed charge-controller IC (BQ24 series) that powers the system from the adapter but fails to send charge current to the cells, or a degraded battery whose internal BMS reports full capacity to prevent overcharge even though cells are depleted. Gas-gauge IC mismatch after an incompatible battery replacement is a third cause we see regularly.

We check Samsung Settings Battery Protection settings first (free, two-minute fix if enabled). If hardware, we read the gas-gauge IC via SMBus to confirm cell voltage and state. Charge-controller IC replacement is done under microscope with solder paste and hot-air reflow. New battery comes with gas-gauge calibration and a full charge-discharge verification cycle.
