    DA0X81MB6E0 REV E No VCCcore

    laptop came working but with charging issue, after examining found oxidation in sensing charger resistors after replacement and finishing the work laptop is charging fine but it stopped working, VCCcore is not coming at all not even a micro second,
    3.3v, 5v, 1.20v, 1.05v, vccio 0.95v, 1.8v all are available and okay
    missing vcccore and vccsa
    cpu controller have 5v vcc and vr_on is 3.3v
    tried other bios files but no luck
    cpu resistance to ground is very good 17.8 Ohm
    laptop now give 1 caps lock blink which means CPU failure, tried to change the Cpu controller with one from spare parts board but same problem,
    PWR_good_3 is 3.3v

      Asus Prime x299 Deluxe - no VCCIO VCCSA voltages
      by lol999
      Motherboard after starting show Q code 00.
      No shorts on any rail ( at last I can't finde any)
      All voltage are correct on SIO - 3.3V, PCH power 1V , DDR 1.2V, SPI 8 leg 3.3V
      Nothing get hot, PSU starting, all lights came ON....
      One thing i can see incorrect is no VCCIO and VCCSA voltages and no main power on CPU.
      After deep looking I found dead Synchronous Buck converter CSD97374Q4M that is powering VCCIO for CPU but after replacing it nothing changed. Voltages on it are correct....
      This buck converter is PWM'ed by Asus DigiVRM ASP1405I-62T. Can't finde any datasheet...

      acer la-e921p dramrst missing but vcccore present!?
      by myth77
      This laptop came with problem turning on, no picture. PU1401 was getting hot and shorted on NVVDDS_BST1 line. After replacing all was ok on first...i have every voltage, even vcccore, but no picture...then i noticed that dramrst was only 0.07 Vol. First, i dont understand how it is possible to have vcccore without dramrst!? tried with two different bios but the same, signal DDR_DRAMRST# only rises to 0,07V. plt_rst is ok. I tried three different ram sticks. Any ideas?

      boardview and schmetic attached...

      Asus G512LI VCCCore raise and drop
      by battery.12v
      Hello guys, Asus G512LI, came with 3.3V drop down immediately .... 5V was stable ... after search and work found that +3VSUS_MUX is the issue (caused by U4701A TUSB1146RNQR) , left off the ic .. 3.3V came up again stable ... after power on laptop turn on for 3 seconds and power off ... VCCcore raise 0.9V for 1.5 seconds and drop down all other voltages do same thing ... Ram voltage , Gpu voltages, concerning VCCGT 0V all the time

      Does a vccio short mean bad cpu?
      by motanya
      This laptop, hp 1030 g2 OLDMAN-6050A2848001-MB-A01 came in with a burnt AKVH ic, removing it, the 19v short goes away but there is very low resistance on the coil after the chip(1.6ohms), replacing it, the laptop turns on but no display, cpu is cold and the chip overheats, does it mean the cpu is dead or something else is dead.(From most hp schematics, I have seen them use the chip for vccio, not sure though, I stand corrected)

      No schematics or boardview for this board

      asus gl502vsk no +vccore
      by myth77
      This laptop i believe have all voltages...no short, but i can not get +vcccore to rise. On PWM CONTROLLER NCP81205 i have 5v, i have all_system_pwrgnd 3,3V but it is not opening +vcccore. The cpu i7-7700 resistence on +vccore is 2.5 ohm i believe its fine. I get +1,2 volt, i have +vccsa, +vccio but no +vcccore. All other voltage on the board present(gpu, pch, ite...) only +vcccore missing. Already tried two dumb bioses but nothing.
      On PWM CONTROLLER NCP81205...... P_SVID_DATA_X1, P_SVID_CLK_X1 are 1V but P_SVID_ALERT#_X1 0V..i dont know is this ok? pins 18,19,20 i have 2V, pins 21,22 0V....
