Laptop Battery Drains in Sleep Mode
In most cases, the issue of Battery Drain in Sleep Mode on a Windows Laptop, especially when its Lid is closed is usually due to the Lid Closing Action not being associated with a 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 10 and Windows 11 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.
With this understanding, let us go ahead and implement the two steps required to fix the problem of Fast Laptop Battery Drain in Sleep Mode When its Lid is closed.
