Clevo P775TM1-G Spare USB Lanes

[DoenerBoy123]

Hello folks!

 

I’m currently modding my Clevo’s keyboard. Like on lots of these machines, my keyboard backlight burned out, and I’m not in the mood at all to buy a new keyboard just because of that. So far, I’ve completely replaced the stock LED strip with an addressable one. It works as intended and is a huge upgrade over the stock LEDs, but it’s still far from perfect. I’m controlling the LEDs with a Nollie 1 controller, which works with either SignalRGB or OpenRGB, completely bypassing Clevo’s crappy software.

The problem I’m facing now is finding an unused USB port to connect the controller to. I thought about using the webcam or fingerprint reader data lines, but I don’t want to lose any features for this mod.

So, the big question: does anyone know of unused pads on the motherboard that I could connect the controller to? That would be awesome for this mod! I’ll post a follow-up once I’m done with it.

 

Thanks!

Hey mate sounds like a great project!

Here's  a link to the service manual / schematic for the board, you might be able to find something unused on here

Okay so I might found something promising. The service manual mentions a 3G/LTE port that also carries one usb 2.0 port. The pads of the slot seem to be present, but just left unused as this laptop never had an option for using WWAN network cards. To reach the usb pins I have to fully disassemble the laptop. I will give it a try the next days and report back whether those pins are actually working or not. If successful, I also gonna write a follow up regarding the keyboard ARGB mod as it might be quite useful for lots of people here, especially for those with dead keyboard backlights
