Issues

  • TPM. At the moment there is only basic support inside coreboot...
  • Boot time issues ( keyboard rest timeout )
  • ultrabay hot plug (event missing?)
  • some power management states missing

Nvidia GPU

State of dual graphics on Lenovo Notebooks: Board:lenovo/Nvidia_Optimus

Tested OS

  • Linux (through SeaBIOS-as-payload and GRUB-as-payload)
  • Windows (version>=7, through SeaBIOS as payload with proprietary VGA BIOS)

Proprietary Components Status

  • CPU Microcode
  • FDT(Flash Descriptor Table) => Always needed
  • ME(Management Engine) => you do not have to touch it(just leave it where it is)
  • GbE(Gigabit Ethernet embedded mac) => you do not have to touch it(just leave it where it is)

Flashing

T520 has a ST / numonyx M25PX64VG 8 MiB flash chip in a VDFPN8 package or a Winbond W25Q64.V 8MiB flash chip in a SOIC-8 package.

All Battery's and the Power-supply must be disconnected before flashing.

Next to the flash chip is a connector solder place "J100" where it is connected to.

-------- side to the screen     --------
NC  VCC  HOLD  CLK  MOSI
NC  CS    MISO  WP    GND
-------- side to the palm rest -------- 

We can see that the connector is very similar to an SOIC-8 flash pinout.

VCC     -- 8 --+-+-- 1 -- CS
HOLD  -- 7 --+ +-- 2 -- MISO
CLK     -- 6 --+ +-- 3 -- WP
MOSI  -- 5 --+-+-- 4 -- GND

Here are two picture showing the J100 solder place and a connector soldered to it.

Vendor firmware locks the flash and so you need to flash externally (unless until someone figures out a way around it).
