## Flashing instructions
|
|
|
|
|
|
|
|
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].
