How often should I service my notebook (lenovo yoga 13)? I haven't open the casing and clean since I bought it 3 years ago...also am thinking to apply some protection like a vinyl skin and matte screen protector on it coz the rubbery side of the display is chipping away...
Can any sifus here recommend a computer shop where I can get all these done? Or is it better to just order them online and DIY?
Thanks for answering!

Since your notebook already about 3 years old, i assume your warranty is already over. You can DIY your own laptop, can search for tutorial on youtube for that. For the vinyl skin i remember there is service like that is lowyat plaza last time. How about you go there and have a look. Just remember to go straight to either level 3, 4 or 5 (level 4 & 5 is recommended). While you were there, you can go buy the material and equipment that you need to clean your laptop.
