Problems With my Keyboard

I was surprised last Wednesday night after opening my computer. It processed very slow and it won't open thoroughly because a message was flashing on the screen telling something like,"there is no attached keyboard in your computer. I also noticed that the Num lock light is not flashing. I checked its connection but still it won't go through. I ended up buying a new keyboard. I guess not all electronics and gadgets are safe products. Right guys? If you are also looking for safety products especially for work needs, you can try to browse it in the net. I also read a warning in my keyboard that says, "Warning: To reduce risk of serious injury, read safety and comfort guide provided with product. So people out there including me of course, we have to be very careful when buying electronics and other gadgets. Never forget to read the safety instruction before using it. I am happy that my keyboard worked again. Cheers!
