I have an HP Omen X laptop 17.3"
The "E" key came off as I was foolishly trying to remove to clean a spec of food underneath. In doing so, the plastic component which connects the key to the laptop broke and I need a replacement. Customer support only offers to replace the whole keyboard which seems quite excessive to me.
Specifically, the perimeter of the hole which allows the plastic to "hook" onto the laptop has broke.
Where might one find a spare plastic "foot" for a particular laptop's keyboard?
