Arduino Yun Linino side dead

failed to understand how my arduino yun died, I've always fed with micro usb cable, all you did was install nodejs and all good, the last thing you install some modules were nodejs. then do not use it for 3 days and when I did .... died?

if I could see the console linino might think, but I've never been able to see anything on serial arduino monitor, or putty.
