I have 5 slow blinks and 3 fast blinks on caps lock so I have a BIOS problem. I reset the memory and the Li-ion battery. Next step is to reset/replace the CMOS battery, but I can't find it. I haven't completely disassembled and am hoping I don't have to.  I read somewhere that the HP15-dw1001wm doesn't have a CMOS.  Help please?

Hi:

 

The main internal battery also serves as the CMOS battery.

 

If you look at chapters 3 and 5 of the service manual, you will find no RTC/CMOS battery part number listed, nor a procedure to remove or replace a RTC/CMOS battery.
