Toshiba Satellite PRO (european) A50-EC stuck on dynabook logo

[Bartoloni]

This laptop stay on Dynabook logo for hours (after this boots normally to windows)

i have the dumped bios, and the bios that came from Toshiba Site

these are the same version ( 2.80 )

if any one can Rebuild a new one.. or better... has a dumped one from a working machine this can be great,

i think i will replace the EEPROM to avoid issues with it.

very thank you to all you guys!

Sorry SMDFlea,
here the other data:

Satellite Pro A50-EC-1k9
Part NO: PT5A1E-1E5004IT
SERIAL NO: 21070937H
SC: A1PT5A1E11U4

UUID: 807756C9-A46A-EB11-8145-C83231070937

i'm requesting to owner the rights to remove the mainboard (to retrieve the model to the back side)



P.S. the EXE file from toshiba site can be extracted using the "/extract" parameter

Motherboard removed, but there are just some minimal texts... (never seen something like that)

Try this bios.

Thank you SMDFlea, just flashed, but still on dynabook logo

the original eeprom i 127mb .. the "tecra" bios was 64mb (and also the one coming from yoo) ... SMDFlea do you think i can use a 64mb eeprom?

btw seems that right now the system is booting fast if i remove all subcards/keyboard/mouse/touchpad from teh main board (before with the original bios this is not happening)


P.S. or... the ME region is copied from the EC to and offset after the 64mb?

You can`t use a smaller size bios chip. I rebuilt your bios with the 7,680KB update extracted from the exe ,and cleaned the ME firmware. The bios is as good as i can make it. I can`t give you any more help,i think you have a hardware problem.

Yep, found the issue is something related to the PD controller of the Type-C connector, i can bypass the waiting time adding a 56K resistor to the CC1 signal (to ground) .. this make the port useless (can be used as a 2.0 with an adapter i think) but the laptop is now starting correctly.
very thank you for the BIOS, now i'm using the one provided by you.
