Why my computer only works when it's plugged in to a charger? and How to fix it in Vancouver?

One of the most common questions we receive from customers who visit BC Computers stores in Vancouver is, "Why does my laptop only work when it's plugged in to power?" No matter the brand of the laptop wether it's a Lenovo, Dell, HP, Asus, Razer Blade or Apple MacBook This issue is a common concern among laptop users, and it often indicates a problem with the laptop's battery health. It indicates that the battery health is likely degraded or faulty. Here are some additional factors to consider in such a scenario:

  1. Battery Degradation: Laptop batteries have a limited lifespan, typically measured in charge cycles. A charge cycle is counted as one full discharge and recharge of the battery. Over time, the battery's capacity diminishes, and it may no longer hold enough charge to power the laptop independently. If the laptop only operates when connected to a power source, it suggests that the battery's capacity has significantly deteriorated.

  2. Battery Calibration: Sometimes, a laptop's battery might not accurately report its remaining charge due to calibration issues. In such cases, even though the battery may have some charge left, the laptop may not recognize it. Calibrating the battery can help in reestablishing accurate reporting and ensuring the laptop functions properly on battery power. Consult your laptop's user manual or manufacturer's guidelines for instructions on calibrating the battery.



  1. Battery Replacement: If your laptop consistently requires a power source and the battery doesn't hold a charge, it might be necessary to replace the battery. Most laptops have removable batteries, while some newer models have integrated or sealed batteries. If your laptop's battery is removable, you can usually purchase a compatible replacement battery and follow the manufacturer's instructions for installation. For laptops with integrated batteries, it is best to consult an authorized service center, BC Computers in Vancouver or the laptop manufacturer for battery replacement.

  2. Power Adapter Issues: In some cases, the power adapter or charger might be faulty, resulting in the laptop not receiving sufficient power from the adapter. This can mimic a battery problem, where the laptop only operates when plugged in. To rule out power adapter issues, try using a different adapter or borrow one from a similar laptop model to see if the laptop functions properly without relying on the battery.

Remember, it's important to exercise caution and follow proper safety guidelines when handling or replacing laptop batteries. If you're unsure about performing any battery-related procedures yourself, it is recommended to seek professional assistance.
