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.
- 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.
Ist dies eine gute Frage?
