Well it is possible that you have a dead motherboard, however there still remains the question of why would your motherboard just suddenly up and die while it is being transported from one location to another.
Here is what I suggest you try, the CMOS battery which is located on the motherboard can die, once the system is disconnected from the AC power supply, things can get crazy.
A dead battery can cause start up issues.
Make sure your CR2032 battery is a fresh one.
Computers can be the most finicky pieces of electronics you will ever encounter, they can almost convince you that they are possessed by a demon! LOL
I realize you are not in the USA and most likely use 230 volts.
Power is generated the same way all over the world, it is Alternating Current, AC for short.
The frequency range may be different in different countries, but it is still based on the same principle of Hertz, such as the USA is 60 Hertz plus or minus 5 Hertz.
The AC sine wave is basically the letter S
laying on its side. The S has a horizontal line running through it at its center.
As AC power is produced, it is done by a the use of a turbine, which rotates and outputs two different electrical fields, a positive one and a negative one.
As the energy produced becomes positive, the sine wave raises up over the horizontal line until it peaks out, like a mountain, then as the energy goes more negative, the line drops down to the line and then below it like a valley and it peaks at the same level it peaked at the positive mountain peak.
This process in the USA happens 60 times a second, the line goes from left to right, peaking and dropping, peaking and dropping up and down that horizontal line forming what looks like one S after another connected to one S after another. Too bad the keyboard does not have a characters that allows me to show you what it looks like.

The point I am making with all this gibberish is that even in your country reverse polarity can be a problem with some electronics.
