+# Lenovo T420s
+
+## Flashing instructions
+The flash IC is located at the bottom center of the mainboard. Sadly, access
+to the IC is blocked by the magnesium frame, so you need to disassemble the
+entire laptop and remove the mainboard.
+
+Below is a picture of IC on the mainboard with clip attached, and a picture of
+the Raspberry Pi with cables attached. In this case it's a Winbond flash chip
+"W25Q64.V".
+
+
+
+
+For more details have a look at [T420 / T520 / X220 / T420s / W520 common] and
+the general [flashing tutorial].
+
+Steps to access the flash IC are described here [T4xx series].
