After replacing the motherboard, how do you get it to be accepted?

I’ve replaced the motherboard in my XE500C21-H04US. I did this because the power adapter broke on the original motherboard. The original motherboard works just fine in all other respects; it just is unable to charge the battery. In fact, if I reinstall the old motherboard I can reinstall the OS and everything works fine. I have reinstalled it twice now to confirm.

With the new motherboard I am able to charge. It starts up to a black or blank screen. The system does not seem to accept the new motherboard. Is there something special I must do to get the new motherboard integrated?

I have tried a number of ideas and have included them below with the results.

Power on:

  • Screen stays off (un-lit)
  • Power button light is on
  • After about 17 seconds, a sound plays through the speakers
  • If I hold the power button for 3 seconds, it powers off
  • Pressing the mousepad or a variety of keys seems to have no effect (ctrl-d, ctrl-c, ctrl-z, ctrl-t, esc, random keys, …), neither before nor after the chime sounds.
  • Power on while holding the reset button on the bottom of the machine:
  • Screen illuminates, but remains "black/blank"
  • Press the power button once and it powers off immediately

Power on dev mode:

  • Same as powering on in normal mode, except the chime sounds after about 50 seconds

Power on with reset button in dev mode:

  • Same as normal mode

Power on, with reset button, wait and insert recovery USB:

  • Screen remains "black" (but on)
  • When I insert the disk, the screen flashes off then on again and then remains "black" (but on).
  • The USB disk light seems to indicate that data is being read. I leave it in for several minutes.
  • When the LED light on the disc is idle (SanDisk "breathing"), I remove it.
  • The screen turns off but the power button led remains on.
  • Pressing the power button for 3 seconds powers off.

It took a while to convince myself, but the display was the issue. I guess I just got confused because there were no problems with the display when I went back to the old motherboard … until just recently. Plugging in a secondary display confirmed that all was well.

The new motherboard is working fine and does not really need anything special to activate. After I completely unplugged and reinstalled the display everything was visible and working normally!

It sounds like the new motherboard's BIOS/UEFI hasn't been configured yet.

Is there any way you can press a button at the computer’s startup to boot into the new motherboard's BIOS/UEFI utility? If the motherboard uses UEFI mode (as most new motherboards do), you may be able to download any drivers that the motherboard needs using the utility.

Booting into the BIOS/UEFI utility can also allow you to change your system's boot order so that your computer boots from your hard drive.

The special key you need to press to access the BIOS/UEFI should be on the motherboard's website. You may have to poke around the utility a bit to find the screens that allow you to download the drivers and change the boot order.
