I have ASUS x550Jk and my BIOS is American Megatrends 303 2175.I15X550.007 F02S080001, which is the latest version of BIOS for my laptop.
Since yesterday when I start my laptop it automatically goes to BIOS and asks to set date and time. Date and time that BIOS shows is the current date and time, so if I just exit from BIOS my laptop boot up just fine; but when I choose 'save and exit', it automatically loads BIOS, not my windows.
I found that the problem might be my CMOS battery but laptop is only half year old. How do I prevent this from happening?
