no image, cpu gets warm no chime . Touchpad vibrates but keyboard light does not come on. Board are clean. can't turn on dfu
L7410/20/30 and L3500 0v
PLT_RST_L 3.3v
R3090/98 are ok

Don't expect iGPU voltage untill high graphics load is detected.

L3500 should have 5V only when USB device is inserted into corresponding ports.

If PLT_RST_L goes high, power on sequence has been completed; including CPU core voltage.
The board should be able to enter DFU.
Be sure to follow all the steps from tutorial.

Performs everything according to the instructions and still nothing
Can I force DFU mode by SOC_FORCE_DFU up to 1.8v using the PP1V8_S4 line (R4035) ?

 

[2informaticos]

Sorry, I just saw you have 00239 board; no DFU there!

You should try known good BIOS, clean ME.

 

[MarcinRdm]

Do you have a known good bios ?

Still the same. I use ezp2019+.
I also used the DS-809 but still no change.

 

[MarcinRdm]

Can anything else be done ?

 

[2informaticos]

If BIOS has been correctly done, probably bad CPU...
