Laptop Won't Charge

       There are several reasons a laptop could be having trouble charging. Examine the outlet, cord, and connection first, since these are easily identified and often fixable problems. If you can't find any issues there, changing your laptop settings or resetting its battery management can sometimes solve the problem. If not, replacing the battery might be unavoidable.

1. Unplug for a few minutes, then try a different outlet. Unplug the laptop, wait a few minutes, then plug it into an outlet in a different room. Some users report that a laptop power adapter can temporarily stop working to protect itself from a perceived issue with the power supply.
2. Examine the cord. Examine the entire length of the power cord for tears, dents, and worn-down insulation. If you notice any, or if the power brick is warped or smells like burnt plastic, the cord is probably faulty.^[2] You'll need to purchase a new cord for your laptop.
3. Let the computer cool down. If your laptop battery feels very hot to the touch, excess heat could be interfering with the charging process.^[3] Shut down the computer and let it sit for several minutes to cool down. If you haven't cleaned your laptop vents recently, blow a can of compressed air into the fan vents at an angle, in short bursts, to remove some dust.
4. Replace the charger. Sometimes the adapter (the box in the cord) is faulty, or despite your best efforts you can't repair a loose plug. Try borrowing a friend's charger, or asking an computer store employee to test your charger. If your charger is faulty, buy a new part from a computer or electronics store.
