+## Flashing instructions
+
+![x1_flash_ic](x1_flash_ic.jpg)
+
+You have to remove the keyboard in order to access the flash IC (the chip
+inside the red circle on the picture above), as it is under the wider
+cable (already detached from MB in the picture) connecting the keyboard
+to the mainboard.
+
+The flash IC can be a SOIC-8 one or a WSON-8 one, and may be covered with
+a piece of insulation tape.
+
+For more details have a look at [T420 / T520 / X220 / T420s / W520 common] and
+
+```eval_rst
+:doc:`../../flash_tutorial/ext_power`
+```
+
+Steps to access the flash IC are described here [X2xx series].
