Taiwan-based laptop giant (4)
I believe the answer is:
acer
'taiwan-based laptop giant' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for acer that I've seen before include "Tree of maple family" , "Type of maple" , "ornamental tree" , "Tree or shrub of the maple genus" , "Care about this tree" .)
