How to Bypass BMS (Battery Management System) on a Laptop

A laptop battery pack integrates a battery management system (BMS) that ensures that the battery is kept safe and functional at all times. It’s important to understand this safety measure so you can bypass it if necessary. BMS is designed to keep the battery safe, prolonging its lifespan and preventing the risk of overcharging, which could cause it to catch fire or explode.

It does so by forcing the battery to stop charging once it’s full, even if it’s plugged in. In rare cases, however, you may need to bypass this system and use the battery outside of its normal parameters, for example, when operating on external power or in certain emergency situations. This guide will help you with everything from understanding what BMS does and how to bypass it on your laptop in no time.

Sometimes, you may want to disable your laptop’s battery management system (BMS). This can be useful if you’re using your laptop in an area with a lot of dust or if you’re constantly moving your laptop around. Plus, this can come in handy if you have a bad battery. However, there are some dangers associated with disabling the BMS. 

If the battery pack is damaged, it could overheat and catch fire. Additionally, if the BMS is disabled, the battery may not charge properly, which could shorten its lifespan.
