Hello Everyone,

I have this board that has an autostart as soon as i connect the charger (no POST) and restarts after 20 seconds. cannot be turned off.
I'm suspecting main EC firmware problem (IT8227E-192)
Since this board has only EC_KSI6 and EC_KSI7 pin on keyboard connector to the EC this cannot be programmed trought it.

I would like to know if anyone can give me instruction how to program the EC.
In the Vertyanov tutorial instructions I have seen that alternative is using 8pin direct cable soldered to board.
Anyone knows hows if that is working...

Hey all,

would anyone happen to have a copy of the schematics and BV for a GH4UT LA-L151P rev 1B?

I have everything for 2B but there seems to be a few major differences in the 2.

thx

Hi:

A friend gave me this DELL WD15 dockstation that does nothing. Not detected by computer, no digital output.........just leds shines when it’s plugged in.
Here are the findings, followed by good pictures. :-)

When pluged in, LED3 glows
Measuring some voltage in the circuit.


Inductors
- PL202 has 5V
- PL201 has 3.3V
- PL300 has 1V

V. Regulators
- UT30 has 19v as input and 6V as output. It seems ok.
- UT27 (same reference as UT30, has no input/output voltage).


Thermal find...
