Hi everyone! My laptop is an HP Elite x2 G4

A few weeks ago, the touchpad became less sensitive. The next day, it stopped responding. Then I tried updating the driver, afterwards I then closed the laptop: the numlock button was flashing. I restarted the laptop again, then the whole keyboard began to flash. Then I left it off for a day, and then turned it on. It's completely unresponsive now. The keyboard has been unresponsive for weeks.

Symptoms:

• The keyboard is completely dark (no backlight, no Caps Lock light).
• The trackpad does not work.
• The tablet still detects the "Lid Close" magnet (screen turns off when closed), but "I2C HID Device" is completely missing from Device Manager (even under Hidden Devices).
• Volume buttons do not work in the UEFI/Startup menu.

Things I have tried:

1. Hard reset (30-second power button hold).
2. Uninstalling Intel Serial IO I2C Host Controllers in Device Manager.
3. Cleaning the pogo pins and gold pads.

I am worried it might never work again. What must I do?
