I using the E5-573.

After upgraded RAM and SSD.

Only cold booting is possible.

There is no option to delay booting in CMOS.

RAM 8G ,  SSD Kingmax 256G...

 

I called to ACER after service center... (here is south Korea)

They have no idea and they said to me " before several model had a same problem but E5 model is not that case...".

 

Plz advice to me.. how can I do something??
