Laptop battery won't charge
This is very common, and most of the time it's the cable, the outlet or a setting rather than a broken battery.
Be careful: If the charger or laptop gets very hot, smells of burning, or the battery looks swollen, unplug it right away, don't charge it, and get in-person help.
What to do
Step 1: Use the Chromebook's own charger and plug it straight into a wall outlet.
Step 2: Try the other USB-C port if your Chromebook has two.
Step 3: Check for a charging light near the port.
Step 4: Do a hard reset: turn it off, then hold the Refresh key (the circle arrow) and tap Power.
Step 5: Check for updates in Settings, then About ChromeOS.
Still stuck? If it still won't charge, try a known-good charger of the same type, then contact the maker's support or a trusted repair shop, as the battery or charger may need replacing.
