Does my Asus VivoBook have a backlit keyboard?
Some VivoBook variants are backlit and some are not. If yours lights up via an Fn shortcut, order a backlit replacement; a non-backlit keyboard will fit but never light up.
Asus keyboards vary a lot by backlight: many VivoBook models are backlit, gaming TUF/ROG keyboards use RGB or single-colour backlighting with different connectors, and some budget VivoBooks are non-backlit. Confirm whether your current keyboard lights up and whether the frame is included.
These Asus keyboards mark layout and backlight. Send your Asus model (for example VivoBook 15 X512) to confirm the backlit variant before packing.

Yes. Gaming keyboards use different backlighting and connectors from VivoBook/ZenBook. Match the exact Asus model and keyboard variant.
If your current keyboard lights up (often via an Fn + space or Fn + F-key shortcut), order a backlit replacement. A backlit keyboard has an extra ribbon connector, so a non-backlit replacement will not light up even if it fits.
Single keycaps can sometimes be refitted, but if multiple keys fail, the membrane or ribbon is usually damaged and replacing the whole keyboard is the lasting fix.
It depends on the variant. Some models ship the bare keyboard, others include the top frame/palmrest. Each product page states what is included; match it to how your current keyboard is built.
Most Indian laptops use a US/English layout. Confirm the key arrangement (especially the Enter key shape and extra keys) matches your current keyboard before ordering.
