Taiwanese laptop brand (4)
I believe the answer is:
acer
'taiwanese laptop brand' 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 with winged fruit" , "Tree of maple family" , "Type of maple" , "Care about the maple?" , "Tree or shrub of the maple genus" .)
