Our friend Raja has done it again where I had a little issue with my keyboard where a couple of keys collected a lot of dust and debris. So he gave a good clean and the keyboard is working fine again without any issues at all. Wish I could give him a 10 star review but maximum is five. Thank you once again my friend.,Our friend Raja has done it again where he found a simple solution for my keyboard where there was a lot dust and debris collected underneath the key. He just gave it a good clean and the entire keyboard is working and disruption happened either. Wish I could give the guy 10 stars but maximum is 5. Thanks once again Raja.
