(Does #1 mean #2? What about #3? Is #3 grammatical? What about #5 and #6? Are both correct? I appreciate your help.)

1, 2, and 4 are fine.

3 would be okay if you use 'brought in' for the phrasal verb.

5 and 6 aren't used.

Yes, #1 means the same as #2. Both sentences convey the idea that someone instructed the man to fix the computer.

However, #3 is not grammatically correct. "Was had" is not a valid construction in English. Instead, you can use "was asked" or "was told," as shown in #4.

Regarding #5 and #6, neither of them is grammatically correct either. "Was got" and "was gotten" are not appropriate verb forms in this context. Instead, you can use "was asked" or "was instructed" to convey the meaning that someone requested the man to fix the computer.

So, to summarize:
- #1 and #2 are both correct and have the same meaning.
- #3 is incorrect.
- #4 is correct and means the same as #1 and #2.
- #5 and #6 are both incorrect.
