    compaq m2000 cap problem

    I have 2 identical M2000 motherboards 1 that is working and the other is totally dead.
    i have check the cap values(smd caps) on the working board to cross reference with the dead board
    working caps 198uf 0.06 esr and on the dead board the value is 670 uf 0.09 esr. Do i assume the caps in the identical positon on the dead board need replacing.
    Any help much appreciated

      They look fine i do belive the laptop was dropped at some point very minor crack to the plastic around the dc jack area . The board is dead when you power on no led's comming nothing.
      I have read posts on another forum that the resistor and mosfet near the dc jack do have problems, I have checked these and they both have the same values.

          Pictures of what you're measuring please.
          What are you using for measurements?

                    Yoga3 Pro-1370 Board NM-A321 DEAD no power at all
                    by k370
                    Hi everyone,

                    I have a NM-A321 board that is dead, with no power at all.

                    When I received the laptop, the +5VPMIC line was shorted. Removing the PU3 (ISL95905) solved the short, so I ordered and replaced the ISL.

                    With the new ISL, the short is gone, but still no voltages at all. I measured the following rails:
                    • +3VALW
                    • +5VAUX
                    • 1.2VSUS_PWRGD
                    • 3VALW_PGD
                    • 1.05VAUX_PWRGD

                    Additionally, the ISL95906 (PU3) is not getting any voltage on the VIN rail.

                    The only place on the board where I find any voltage is on the first MOSFETs, specifically:...

                    Nikon D5 – dead, power board issue ?
                    by corrize
                    Hello, the DSLR has heavyly fallen. It is dead : no sign of life and display nothing.

                    When it worked, it always displayed a card present state on LCD display, even when the battery is empty it display a empty battery symbol.
                    I found a dead fuse, I replaced it and a mosfet burnt, I changed it and another fuse burned. Nothing burned after. And I can't find any short circuit anywhere, it's weird.

                    Now, I try to understand how it works.

                    There is two boards (the little one on pictures has no component) : the first is a « power board » : managing...
