Internal Keyboard Cables

[AverageMaleHuman]

I took apart my keyboard after I spilled water on it to let it dry, but after opening it up I noticed a cable disconnected. The cable was disconnected by forceful means (there is no port or connector, it was just soldered on and now it's broken off). There are two cables in total, one 14 pin, multicolored cable, and the disconnected single wire cable. After re-assembling and testing, the keyboard seems to work perfectly fine without the cable attached, including the lights. I'm curious as to what the cable did and if it's necessary to reconnect it.

Make and model keyboard?

Google the make and model and include the word "disassemble" or "take apart" or "repair".

You may find some link or YouTube video that identifies the cable.

Otherwise just keep using the keyboard. When you discover that some key combination or other keyboard aspect is not working then you will know what the cable was doing.

However, many keyboards have some common generic version that is subsequently modified or enhanced to become wireless, USB, PS/2 as required. And perhaps include some other special feature sure as a headset port or built in USB port.

Manufacturers often just add an extra component or two as necessary for the keyboard to work beyond the base configuration. The broken connection may be some such preparation.
