I bought this NUC D54250WYKH few months back. I am not using this very frequently. I have installed Linux mint on this after the Bios upgrade as recommended.
This configuration is as below
Wireless card Intel® Dual Band Wireless-AC 7260 Plus Bluetooth
RAM Crucial 4GB CL11 SODIMM DDR3
SSD PLEXTOR M6M 128GB MSATA
HardDisk HGST 1TB 7200RPM 2.5" INT SATA
Keyboard Mouse Microsoft wireless 800
It has been working without any problems. I have my linux mint power management option to suspend after 30 min. of inactivity. However it is now dead after it went to suspend mode. It does not boot any more. There is no sign of booting/harddisk sound / LED when i switch it on and the screen remains blank. When it went to suspend mode for the last time it did not wake up after any keyboard/mouse input. I had to switch it off. After that it is dead and won't switch on.
I have read similar reports on this forum. I am now planning to take it back to shop where i purchased from. It is still under warranty. Hoping to get it replaced.
This is a serious problem and looks like it has been faced by few people. I request intel to look into this on priority and work on fixing this. Also if there is a way to fix this without replacement please let me know.
regards
