nRF52840 Development Kit not powering up or showing as USB device. No LEDs pulsating.

[Paarth_Ved23]

The device was working well for around 2 weeks and was able to program it via SES, but now on connecting USB cable to the USB Connector (J2) with SW9 at VDD, no LEDs pulsate and it doesnt show up in device manager or in /dev (Ubuntu). I have tried the following:

1. Tried different USB 2.0 cables with different ports and PCs.

2. Tried putting in the bootloader mode by holding down the RESET switch and toggling power.

3. Uninstalled and Reinstalled latest JLink to detect the connected hardware.

Please let me know if i m missing out on something, or anything else i can do to find the the source of the issue. Thanks in advance.
