The BIOS (Basic Input/Output System) is a software that controls the basic functions of your tablet, such as booting, hardware configuration, and power management. The BIOS also stores some important information about your tablet, such as the Machine Type and Model (MTM), System Serial Number (SN), and System Brand ID. These values are used to identify your tablet and provide warranty and support services.
Sometimes, these values may get corrupted or erased due to various reasons, such as a faulty battery, a BIOS update failure, or a motherboard replacement. When this happens, you may see an error message saying "Machine Type and Serial Number are Invalid" on your tablet screen. This means that the BIOS cannot recognize your tablet and may cause some problems with your device functionality.
The good news is that you can fix this error by using a utility program that is included in the system BIOS update package. This program allows you to enter the correct values for the MTM, SN, and System Brand ID in the BIOS menu. To do this, you need to follow these steps:
- Download the latest BIOS update package for your Lenovo tablet from the official support website[^1^]. Make sure you choose the correct model and operating system for your device.
- Extract the downloaded file to a folder on your tablet or a USB flash drive.
- Restart your tablet and enter the BIOS menu by pressing F1 or F2 repeatedly during the boot process.
