I was busy typing updates for my blog and chatting when I noticed something is wrong with my keyboard. I was shocked after hitting letter Y and saw letter X on screen and two other letters. I do not know what is wrong with the letter of my laptop keyboard that caused the mixed up. It took me lots of time typing because I have to make it sure that the letter I am hitting is the same letter reflected on the screen.arghs! I realized that I guess it is because of the dust and needs to be clean. I am thinking of how to clean it or hire someone to clean it for me. I was advised to buy brush and clean it for myself. I might try this one but if it won’t work out I will hire someone to do the cleaning for me.
