alienware 17 R4 power on/off, no post

[reverendalc]

hey all,

i've got an alienware 17 R4 on my hands, LA-D751P BAP10 Rev1.0

when i received it, this was the behavior:
press power button= fan spin, led/kb illuminate for a second, then powers off. no LCD/backlight
<repeat until power is cut>
if i remove the RAM and power on=
machine would power on then LED would indicate bad CMOS batt
if i remove the CMOS batt and ram, i will get NO RAM LED error

i tried several bios dumps from this forum, which all result in CPU FAILURE LED error. some bios will give me full tron lights, others only LCD/lid tron lights.

if i write back original BIOS, i get original errors/symptoms.

have tried disconnecting all RAM/HDD/SSD, various combination of batt/AC power, have tried cleaning ME on all dumps, so on and so forth.

totally at a loss here, help please!!!

followup: if i clean ME on original read, the machine will power on and complete ME initialization, and then start the on/off cycle.

i have uploaded all of my chip reads here. i downloaded a full suite from biosfix however now i cannot write to UG13. it errors out at 12% most often, sometimes 25%, and once at 31%. the chip has been erased. FML

Oops. I guess that's a 1.8V chip. Need to get a 1.8v programmer.

Is the KBC programmer viable in a situation like this?
