There could be several reasons why your Lenovo laptop is not charging and you will have to conduct a series of checks to identify the exact issue. You can start with the battery and the power supply and then move on to others.
Check if Your Charger is working correctly
You use a charging cable with the adapter to charge your Lenovo laptop battery. Check it thoroughly. It should be plugged into the power socket firmly. If there is a tiny LED indicator, it will show if there is power in the circuit.
There can be a light at the point where you connect the charger to the laptop. It may light up to show that power is being received. If despite all this, the battery is not charging, then you must check the battery. Another way to check the charger is to connect to another Lenovo laptop and see if it is working.
The Power Supply Unit
The power supply unit in the laptop is a critical component. The problem you are facing could be due to either a faulty power supply or in the connections. If it’s the power supply unit that is faulty, it can be attended to only at the service center and you will have to carry your laptop to the center to get it fixed.
Using a Old Battery
Your Lenovo laptop’s battery may be old. Laptop batteries typically last 2-3 years depending on the usage and how frequently the device is run on the battery power alone. If the battery is weak, it won’t charge beyond a point or it might stop charging completely.
The only way you can check this out is by removing the battery and powering the laptop on. If the laptop works fine on direct power then the battery certainly needs to be replaced. If you feel the battery is new and can’t be faulty, you can fit it on another laptop and confirm.
The Battery Charging Circuitry
In a typical Lenovo laptop battery charging ecosystem, there are several elements at play. The battery driver may need to be updated. There is a power connector that is soldered on to the PCB and if it has been disturbed for any reason, the battery charging process in Lenovo laptop may not be complete.
