eMMC) -only computer models. To check your computer,
1
Right-click the Start button in the lower-left corner and select Disk Management.

program on the C partition of your hard disk. If you cannot find the drivers for all the hardware
devices that you need there, download the drivers from the Lenovo consumer support website.
