I study this topic: viewtopic.php?p=59795#p59795
But I find there is somethings different.
I have N5010 DG15 with this voltage:
AC_IN_KBC#=.17V
LID_CLOSE#=3.3V
PCH_RSMRST=3.3
PM_SLP_S3#=0V
EC & BIOS firmware sews and OK.
But not start.
so I test voltage on working exact M.B and I see this:
AC_IN_KBC#=.17V
LID_CLOSE#=3.3V
PCH_RSMRST=3.3
PM_SLP_S3#=0V but working fine.
I want to know this voltage existence to laptop start is necessary? so why second one start and work fine without AC_IN_KBC#,PM_SLP_S3#?

see start-up sequence in schematic diagram (p94 or 98)

thank for good advise. I follow voltage according to Power sequence . all exist and good , by pressing power switch KBC_PWRBTN_EC# & PM_PWRBTN# goes to 0 but after power switch press, PM_SLP_S4# not appear on EC. U think it mean we have corrupted HUB(PCH)?

If PM_RSMRST# is 3.3V, BIOS Ok and previus conditions ok then it possible.

I changed PCH(HM57), so.......... When plug power jack turns ON and goes OFF after 1 sec, I sinned on PL4901, resistance 10 Ohm, took PL4901 and connect power jack and turns and stays ON. So there is Short circuit, but I cannot find, I checked 1.05VTT connections but no success. What do you think?

Try to program bios (with clear ME), because you had changed PCH. Maybe it didn't solder?

I sewed BIOS, but what is ME bios?

ME - Managment Engine - is a Intel part for ME-engine in PCH. ME-region is a part of flash IC. Other parts are: BIOS-region (bios exactly), GB-rerion, OEM-region. There is a lot of information about ME.

Wonderful, U have any reference to digging more about this? ( ME-region and .......) and How can I made BIOS, ME_region?

on DELL web bios with clear ME.

I confused, there is some exact techniques to generate ME-Clean Bios files? I mean that Where I can prepare ME firmware and How to send it into the bios files?

Lab DC power supply to short circuit: 1V 2A (find hot elements) or try to find in scheme (+1.05V_VTT) by "brute force" (sorting one-by-one)

I do this before, without CPU , V=1V , current =0.28A there is no hot element, with CPU, V=1 current= 2.13A there is no hot element again!
I checked according to schematic, some route goes to CPU( I swapped CPU), some goes to Clock ( took it and test) and some goes to PCH ( changed IT before), mysterious!

does any one has Clean ME-region BIOS for this laptop? Nobody answered my question about creating ME-region Bios!

Can You be kind enough and Upload ME-Region Bios?

I told you all yet. If you don't see - it is your problem. There isn't ME-region BIOS. Read carefully.
Think, try. Bye.

reball s-bridge or rework it
