HP Notebook - 15s-du1015tu

 

I have the problem CMOS 502 error.

For this error, I have to start my pc with the power cable. Or the laptop never starts.

 

I installed the bios version F.57 as this is recommended by HP Support Team to fix this error.

But the problem is still there...

 

And I can't change the CMOS battery because, I think, there is no CMOS battery in my laptop.

Please help me fixing this BIG PROBLEM!

And, if there is a CMOS battery in my laptop, where is the CMOS battery located?
