If you’re having trouble with your laptop’s AC adapter not working or not working properly, there are a few things you can check before buying a new one.
Verify that the adapter is plugged into the wall outletMake sure the AC adapter is firmly plugged into the wall outlet. Although it sounds obvious, adapters can become loose without your knowledge. If it’s partially plugged in, it may make the adapter look like it’s not working, but it may not be getting power from the wall outlet. When in doubt, a good way to ensure proper insertion is to disconnect and reconnect the plug.
Check the adapter lightMany laptop AC adapters have a power light on the adapter block. Check this light and make sure it lights green if there is one. The power light indicates that the adapter is receiving power.
Check the wall socket itselfSome wall outlets require the light switch to be in the on position to activate the outlet. Many newer homes, condos, and condos come equipped with this type of wall socket. If the light switch is on, verify that the wall outlet is working properly . Use a voltmeter to measure power output and verify that the outlet is functioning properly. Alternatively, you can try another wall outlet. Also, double check your circuit breakers to make sure nothing has tripped or turned off.
Check adapter block connectionsMost laptop AC adapters come in two parts. Make sure the two parts are firmly connected. The two pieces are joined at rectangular box pieces (often called bricks). You can verify the connection by disconnecting and reconnecting all cables.
Adapter not plugged into laptopAlthough it may seem obvious, the laptop adapter can easily become disconnected from the laptop. The metal tip on the adapter cord needs to be securely connected to the laptop for the laptop to receive power from the adapter. Additionally, there is usually a small metal pin on the tip of the adapter or where the laptop connects. Make sure this pin is not bent or broken, as this may cause problems with the laptop receiving power from the adapter.
Laptop power connection portThe power connector usually connects directly to the laptop’s motherboard via one or more solder joints. If the solder joints are damaged or detached from the motherboard, the laptop will not be able to power from the AC adapter. Fixing this problem requires very precise work, either soldering the power connector back to the motherboard or replacing the power connector itself if it’s defective. Sometimes, such problems cannot be repaired and require replacement of the motherboard or power strip.
If you think this might be your problem, it’s best to leave it to a technician, who may need to take the laptop apart to check the hardware.
