  • Base cover

The [Hardware Maintenance Manual](https://download.lenovo.com/ibmdl/pub/pc/pccbbs/ mobiles_pdf/x230s_hmm_en_0c10860_01.pdf) could be used as a guidance of disassembly.

The SPI flash chip (W25Q128.V in the form of SOIC-8 for the author's X230s, but varying is possible) is located at the circled place.

Unlike most Ivy Bridge ThinkPads, X230s has a single 16MiB SPI flash chip.

The general flashing tutorial has more details.
