+The flash IC is located at the bottom center of the mainboard. Sadly,
+access to the IC is blocked by the magnesum frame, so you need to disassemble
+the entire laptop and remove the mainboard.
+
+Below is a picture of IC on the mainboard, with the pinouts labeled.
+
+![t410_chip_location](t410_chip_location.jpg)
+
+The chip will either be a Macronix MX25L6405D or a Winbond W25Q64CVSIG.
+Do not rely on dots painted in the corner of the chip (such as the blue dot
+pictured) to orient the pins!
+
+[Flashing tutorial](../../flash_tutorial/no_ext_power.md)
+
+Steps to access the flash IC are described here [T4xx series].
