Troubleshooting:-Peripherals

I am getting noise from my adaptor.

First confirm that noise is from adaptor only as it can be from laptop also, main power source or socket (like UPS, multi-pin-plug-socket, etc.). To confirm disconnect laptop first if noise persists then connect laptop to a different power source, or socket. If still noise persists then take your adaptor to a technician or contact customer-support.

Keyboard or mouse (either one) with USB port is not responding.

a)     Firstly ensure that your computer is not hang-up (freeze) by operating it thru the other working device (mouse or keyboard).

b)     In case your device is connected through USB hub or switch box, unplug it and plug it in directly to the computer, firmly.

c)     If still no response, unplug and remove all other connected USB devices (if any) and again plug the keyboard but in a different USB hub.

d)     If problem persists, try another keyboard or mouse to verify that the device (not computer) is really defective, on verification contact customer support.

Keyboard or mouse (either one) with PS/2 port is not responding.

a)     Firstly ensure that your computer is not hang (freeze) by operating it thru the other working device (mouse or keyboard).

b)    Check that your deice is connected to the right PS/2 port, as generally keyboard’s PS/2 port is in green and mouse’s PS/2 is in purple color. Unplug the defective device and plug it again to the computer, firmly. If works fine then okay else restart the computer as windows detects the changes and installs the required drivers automatically.

c)     If problem persists, try another keyboard or mouse to verify that the device (not computer) is really defective, on verification contact customer support.

In keyboard some keys don’t work or type even when I press them.

Some fluid is spilled on my keyboard.

Immediately unplug the keyboard, turn the keyboard upside-down and left-right to let the maximum fluid drain-out as much as you can. ProDot keyboard has a unique spill resistant design due to which it allows fluid to drain-out through holes in its body. Plug the keyboard when it is completely dry.
