If you find that the Battery of your Laptop drains in sleep mode, especially when Lid is closed, the problem is usually due to the Lid closing action not being associated with sleep mode or power saving option.
Once the Lid Closing Action is associated with sleep mode or some other power saving option, you should notice a considerable improvement in the Battery Life of your Laptop.
Another common reason for this issue is due to Fast Startup being enabled by default on most Windows 11/10 Laptops.
While “Fast Startup” is designed to provide quick access to recently opened files, it can sometimes cause problems by preventing the computer from shutting down properly.
