1. No, they are not the same.

in 1, it says for a meeting, and in 2 it says to have a meeting.

2. A good word for death could also be "passed away" or "gone away" or exterminated, no longer with us,etc.

3. Yes #4 could be changed into #5, just change some words around, they are not the same, different wording.

1. Two months ago, he was flying to L.A. for a meeting.

2. Two months ago, he was flying to L.A. to have a meeting.

(Are both the same?) They're pretty much the same. The first one implies that he will attend a meeting. The second one could mean he is attending or that he is conducting the meeting.

3. While he was writing a report, the battery in his computer died.
(What other words can we use instead of 'died'?)
For an inanimate object such as a computer battery, you can say it died, its power ran out, it ran out of power. You would NOT use "passed away" or any other suggestions above unless you are referring to a person or animal.

4. He couldn't finish the report because the battery in his computer died.

OR ... because his computer's battery died.
OR ... because his computer lost power.

1. Both sentences are grammatically correct, but there is a slight difference in meaning between the two.

- "Two months ago, he was flying to L.A. for a meeting." This sentence implies that the purpose of his flight was to attend a meeting in L.A.

- "Two months ago, he was flying to L.A. to have a meeting." This sentence suggests that the meeting was scheduled to take place after he arrived in L.A.

2. In the given context, the words "died" and "stopped working" can be used interchangeably.

3. Yes, sentence #4 can be changed into sentence #5, but they do not mean exactly the same thing.

- "He couldn't finish the report because the battery in his computer died." This sentence states that he was unable to complete the report because his computer's battery stopped functioning.

- "He couldn't finish the report because of his battery death in his computer." This sentence conveys the same general meaning, but the phrase "battery death" is not commonly used. Instead, it would be more natural to rephrase it as: "He couldn't finish the report because his computer's battery died."

It's important to note that "battery death" is not a common idiomatic expression in English and could potentially cause confusion.
