power-supply

The problem i am facing is the keyboard (USB) automatically disconnects when there is a fluctuation in the power supply to the speaker. The speaker and the pc both draw power from a apc ups.

The fluctuation occurs because the speaker plug is not tightly connected to the ups power outlet. It is okay for normal work, but a accidental jerk causes the fluctuation.

However after some amount of time (usually within 5 seconds) the keyboard automatically reconnects and windows plays the sound of hardware connected.

This problem will also occur if I manually take out the speaker power cable from the ups power outlet.

My question is whether the problem I am facing is due to electrical issues, or due to software problems.

PC config:

OS : Windows 7 Ultimate

UPS : APC 600 VA

PSU : Corsair TX 650

Speaker : Realtek
