The code is based on autoport and that for X230. Major differences are:
- Only one DDR3 slot
- HM77 PCH
- M.2 socket instead of mini PCIe
- No docking
- No TPM
Tested:
- CPU i5-3337U
- 8GiB SO-DIMM
- Camera
- PCIe and USB2 on M.2 slot with A key for WLAN
- SATA and USB2 (no SuperSpeed components) on M.2 slot with B key for WWAN
- On board SDHCI connected to PCIe
- USB3 ports
- libgfxinit-based graphics init
- NVRAM options for North and South bridges
- Sound
- ThinkPad EC
- S3
- Linux 4.9 within Debian GNU/Linux stable, loaded from SeaBIOS.
Untested:
- Touch screen, which is said to work under ubuntu but not debian.

|
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](Ivy_Bridge_series.md), X230s has a single 16MiB SPI flash chip.

|
|
|
The general [flashing tutorial](../../flash_tutorial/index.md) has more details.
