If your work takes you a lot, a laptop without a usable battery can get in the way. Several factors can cause laptop batteries to fail to charge, drain quickly, or otherwise fail, including aging, damaged power cords, or damaged charging circuits. You can fix most battery problems by purchasing replacement parts. Let’s have a look!
old battery
All rechargeable batteries lose capacity over time. Laptop batteries lose their useful life significantly after only a few years. If you keep using the old battery, its runtime will decrease further until the battery only lasts a few minutes before it dies. To restore lost power, you will need to order a new battery from the computer manufacturer. Most laptops have user-replaceable batteries, but some may require professional disassembly.
bad power cord
A defective power cord can make your battery appear unchargeable – if the cord switches between working and not working, the battery will lose charge at the fastest rate. You can test the power cord by trying to run the laptop on AC power with the battery removed. If it works intermittently, it may be a loose connection.
charging circuit
If your laptop still fails even with a new battery or power cord, the internal charging circuitry may be damaged. If the wires inside the laptop from the power cord to the battery are damaged, the battery will not charge properly.
battery usage
Laptop batteries don’t need special treatment like some old rechargeable batteries. They don’t “overcharge” and don’t need to be fully discharged before each charge. If your laptop shuts down while you seem to have power left, you can try a full drain to reset the battery’s calibration. However, this process will not actually repair a damaged battery. If your computer becomes very hot during use, you may need to remove the battery while using the laptop on AC power, as heat can shorten the life of the battery.
