NUC dead after suspend mode

Hello people,

I made 2(!) dead NUCs during last year. Every time it happened after my NUC went to sleep (suspend mode).

I was not able to switch it on with power button. Only ethernet LED was flashing.

Now I have my 3th NUC (warranty exchange without any problem) but I would like to know if there is some hardware problem or bios issue...

I searched Intel forum and I found this similar topics:

NUC D54250WYKH not booting

Intel NUC D54250WYKH won't power on

NUC dead after suspend mode in Ubuntu 14.10

D54250WYK power on problems

D54250WYKH no power light after hibernate, Ubuntu 14.04, latest BIOS

My NUC is D54250WYKH with Fedora Linux.

Should I avoid to use suspend mode?

Have you reports about this issue from other users? Will you solve it?

Thanks,

Antonin
