Cracked or damaged the back of your Lenovo 100e Chromebook? This is a brand new replacement top cover (also called the back cover or LCD back cover) specifically for the Lenovo 100e Chromebook 2nd Generation, model AST 82CD. The part number is 5CB0T70806, and it's in black to match the original. It's the plastic shell that covers the back of the screen assembly. If your Chromebook took a tumble and the back is broken, or you're doing a repair/refurbishment, this cover lets you replace just that part instead of the whole screen. Installation requires some tech skills – you'll need to carefully open the device, disconnect the LCD cable, and transfer the internal components to this new cover. Not for beginners, but if you're handy or run a repair shop, it's a straightforward fix. It's a genuine-style part, not necessarily from Lenovo, but made to fit perfectly. Great for schools, IT departments, or individuals who want to extend the life of their Chromebooks. Keep those educational devices in service! Always make sure your Chromebook model matches exactly (check the label on the bottom) before ordering. A cost-effective way to fix a common damage point on these popular school laptops.
