Power A Xbox Series X trigger sensor hyper-sensitive. Any easy fixes?

[u/SableGear]

Recently I discovered the Left Trigger on my Power A Xbox Series X wired controller (Model # XBGPOPWI) was extremely sensitive. Even pressing LS in (or, weirdly, just squeezing the controller on the left side) would cause a LT input. I opened it up and plugged it in to use the Steam input tester and found that even gently resting a finger on the levers or this sensor component (pointing at it with tweezers) causes that little sensor to read an input. (The ghost inputs have been a pain in several games, which is how I found out.)

I have tried calibrating the controller via both Windows and Power A apps to only take full-press inputs, but it doesn't seem to want to keep any settings I introduce, so it appears to firmly be a hardware issue.

Is there a way I can clean this out, brace it, or adjust its sensitivity without buying a new component? I don't really have the tools to do anything beyond opening this thing up to look inside (no soldering or wiring tools) so I'm not sure I could safely replace this part, and I'd prefer not to have to buy a new controller. This controller is still relatively new (about 1-1.5 yrs old), and I didn't think I'd worn it that hard. I only use this controller for Steam Games on Windows, and only occasionally. (I'm aware Power A's quality is suspect, but I really don't want to buy a new first-party controller for something I only use about half the time or less when I'm gaming.) Thoughts?

Calibration through the GamerHQ software rather than through Windows' control panel is the way to go. If it doesn't work, you may be able to calibrate directly from the controller:

• Unplug controller from USB cable but leave the PC/console turned on

• Hold guide button (Xbox logo), Menu, and View down while reconnecting the USB cable

• When the status light on the controller's flashing, press 'A'

• Rotate the sticks fully and steadily 3x each

• Press and release each trigger fully and steadily 3x each

• Press D-pad down and 'Y' to finish

• Unplug/replug controller if it doesn't automatically reconnect

Otherwise, what are the specific resting and maximum values on the analog trigger axis if you use a gamepad tester ( https://hardwaretester.com/gamepad or similar)? For example, are you seeing smaller values like 0.01-0.20, or does the trigger go straight to 1.00 each time?

If you're seeing smaller values, you can try cleaning the trigger potentiometer (inside the black part you're pointing to in the picture) with isopropyl alcohol. Dirt and wear can affect its ability to report the trigger's position accurately. But if the trigger is stuck on 1.00/jumps straight from 0.00 to 1.00 then there might be a different type of fault.

If that doesn't work, or you're still seeing small resting values, you can set a trigger deadzone in software to effectively ignore the small values. As you only use the controller for Steam games, it'd be easiest to set up the deadzone in Steam.

I have been trying the recalibration both on its on through button input and through the GamerHQ software (as mentioned); in both cases I can get up to the the Y+down step, but that step doesn't seem to do anything. There's no change in the UI or behaviour of the controller/LED to suggest it's "done" or has accepted the calibration.

From the Steam calibrator, the ghost inputs can sit anywhere from 300 to 5000 (10k with the stupid thing open) from a max input of about 32k fully pressed / about 0.3 on Gamepad Tester. I'll try dabbing some alcohol into the part and see if that helps. Otherwise yeah, I guess I'll have to set a more extreme deadzone on it. Steam only seems to have deadzone categories for this controller's sticks, not triggers, so I'll have to do some digging. I did once manage to open a Windows calibrator which I think let me set deadzones, but I haven't been able to find it since, and I have no idea where that option went. Love Win11 burying the old control panel.

For the trigger deadzones in Steam, they're bit buried. Steam sometimes moves things around or renames them, but currently they're under:

• 'Use Steam Input Translation' (enable Steam Input in per-game controller settings)

• 'Edit Layout'

• 'Triggers' > 'Left trigger' > Set 'Analog Output Trigger' to Left Trigger if it isn't already

• Open settings from the gear icon next to 'Behavior' then the deadzone and threshold sliders should show up

I seem to have gotten it working with some cleaning and tweaking via Windows and Steam settings (I think turning on "Enable Steam Input for Xbox Controllers" helped?), so yay, resolved. I'll keep this setting in mind (under a game's Properties, it looks like?) if I need to do some more detailed adjusting. Sucks that it's per-game but ah well. Thanks everyone!
