DEAD cmos battery OMEN Laptop - 15-en0013dx

[ytes]

I have a cmos 502 error, which is a dead cmos battery. I opened it up to replace the cmos battery and find out its soldered to the motherboard somewhere..... I saw on another forum I should send it in for repair at an HP service center thing. And I tried to fill out a ticket or something but its virtually impossible with their revolving door of a support system. How do I go about doing this..... thaannkss
