Background and Information
The Lenovo S21e-20 is a lightweight laptop computer with an 11.6" HD LED display (1366x768). It is available in a silver color, with a 32 GB or a 64 GB hard drive, 2 or 4 GB of memory, and completed with Windows 10 Home 64. Older models, however, may have previous versions of windows pre-installed, such as Windows 8.1. In addition to it being small, it is practical- the 23.2 Whr battery allows up to 5 hours of usage which is perfect for the on-the-go user. Due to this device having several different optional features such as the hard drive and memory space, one may need to take this into account when attempting to fix a desired issue. Please refer to the box the device came with or the computer specs to see which specific model you have.
