Laptops will work without a battery as long as they are plugged into the AC adapter. Disabling the battery within Windows or physically removing the internal battery completely allows a laptop to run on the AC adapter alone without any potential for damage and can even help prolong the battery’s life by reducing the number of charge cycles.
Gaming laptops have bad battery life because their high-performance processors (CPUs) and graphics cards (GPUs) can use up to 10 times the amount of power needed for normal laptop components. Additional features common in gaming laptops such as high-resolution displays, RGB lighting, and louder speakers also reduce battery life.
How to fix a laptop that only works when plugged in by disabling and re-enabling the ACPI-Compliant Control Method Battery and restoring the default power schemes in your power profiles within Windows 10. These methods should work for HP, Dell, Lenovo, Acer, and other laptops that won’t turn on unless plugged in.
