This laptop doesn’t have CMOS battery.

Jim, the display panel is a sealed unit so opening it up and replacing both antenna cables is not an option.

You have a few options to make the wireless connection working again:
1. Expensive but reliable option. Replacing the entire display assembly. Maybe you can find a pre-owned not very expensive display on eBay.
2. Cheap but difficult repair. You can buy a set of wireless antenna cables. They are pretty much standard so the brand doesn’t really matter. Cut the damaged heads off as close as you can and try soldering new cables. The problem is HP Spectre x360 13-4100 has a very short Wi-Fi cables and you will have very limited space to work.
3. Cheap but also difficult repair. You can try removing the damaged heads from the existing antennas and replacing them with the heads from the new cables.
4. Cheap and fast. Buy an external USB Wi-Fi dongle for about $20. Hopefully the signal will be strong enough to cover your needs.

For options 2 and 3 you will need a microscope and micro soldering gun.

Much to my horror I discover where the wireless card and antennas connect or are supposed to; that both the connection of wifi card and antennas were not staying in place. Its a tight fit and trying to move around and connect the antenna to wifi card is tight. But as it turns of both the contacts on the wifi card and antennas have been forced in so roughly that instead of snapping on. They are bendt. Each should be a circle with one easily and firmly snapping into the other. Instead of being a nice round circle like two buttons snapping together. They have been mushed or mangled to the point where they will not snap together. HP did a horrible job both with this design and when they worked on my computer.

I am in the process of trying to replace the card and antennas. I tried to see if I could fix the rounded parts but just to bent. HP service / repair said sorry but I could have do this. I cant find any information about the wiring for the antennas other than hp saying how hard it is and send it end for additional charge. They did it the first place. I was hoping you had some information or pictures about the antennas.

I first thought about cutting of bad ends and wiring new ones on but not much space or extra length. I was thinking maybe a could wire it better myself. Any help or insight would be greatly appreciated. Sorry for the long explanation.

Sincerely……………………….Jim W.

ali, you can see the motherboard model in the step 19. It’s printed on the motherboard: DAY0DDMBAE0.
Looks like it’s available on eBay. Also, you can google the model number and probably find some other sellers.
