+# Lenovo ThinkPad T440p
+
+This page describes how to run coreboot on [Lenovo ThinkPad T440p].
+
+## Required proprietary blobs
+
+Please see [mrc.bin](../../northbridge/intel/haswell/mrc.bin).
+
+## Flashing instructions
+
+T440p has two flash chips, an 8MB W25Q64FV and a 4MB W25Q32FV. To flash
+coreboot, you just need to remove the big door according to the T440
+[Hardware Maintenance Manual] and flash the 4MB chip.
+
+![T440p flash chip](t440p_flash_chip.jpg)
+
+To access the 8MB chip, you need to remove the base cover.
+
+![T440p 8MB flash chip](t440p_all_flash_chips.jpg)
+
+The flash layout of the OEM firmware is as follows:
+
+ 00000000:00000fff fd
+ 00001000:00002fff gbe
+ 00003000:004fffff me
+ 00500000:00bfffff bios
+
+After flashing coreboot, you may need to re-plug the AC adapter to make
+the laptop able to power on.
+
+## Known Issues
+
+- No audio output when using a headphone
+- The touchpad is misconfigured, the 3 keys on top are all identified
+ as left button
+- Cannot get the mainboard serial number from the mainboard: the OEM
+ UEFI firmware gets the serial number from an "emulated EEPROM" via
+ I/O port 0x1630/0x1634, but it's still unknown how to make it work
+
+## Untested
+
+- the dGPU model
+
+## Working
+
+- boot Arch Linux with Linux 4.19.77 from SeaBIOS payload
+- integrated graphics init with libgfxinit
+- EHCI debug: the port is the non-charging USB2 port on the right
+- video output: internal (eDP), miniDP, dock DP, dock HDMI
+- ACPI support
+- keyboard and trackpoint
+- SATA
+- M.2 SATA SSD
+- USB
+- Ethernet
+- WLAN
+- WWAN
+- bluetooth
+- virtualization: VT-x and VT-d
+- dock
+- CMOS options: wlan, trackpoint, fn_ctrl_swap
+- internal flashing when IFD is unlocked
+- using `me_cleaner`
