Provide disc to correct software problem without lead for laptop - if it crashes it could be disastrous (9)
I believe the answer is:
doodlebug
'without lead for laptop if it crashes it could be disastrous' is the definition.
I can't judge whether this defines the answer.
'provide disc to correct software problem' is the wordplay.
'provide' becomes 'do' (do can mean to provide or serve up).
'disc' becomes 'O' (disc-shaped letter).
'to correct' becomes 'dle' (I can't explain this - if you can you should give a lot more credence to this answer).
'software problem' becomes 'bug' (I've seen this in another clue).
'do'+'o'+'dle'+'bug'='DOODLEBUG'
Can you help me to learn more?
(Other definitions for doodlebug that I've seen before include "World War II flying bomb (V-1)" , "may be cruise missile" , "WWII flying bomb - mineral detector" , "WW2 rocket" , "German bomb otherwise known as a V-1" .)
