After a failed or incomplete BIOS update, my laptop started acting abnormally. The touchpad stops working after shutdown and only resumes function when I close and reopen the lid. It frequently switches to tablet mode even when in laptop position, and oddly, the keyboard and touchpad remain active in tablet mode, making it unusable. Additionally, the Num Lock light stays on even when the laptop is completely powered off. These symptoms seem interconnected, possibly indicating firmware corruption. The system occasionally returns to normal, but the issues always come back after a few hours, suggesting the BIOS update didn’t apply correctly.
