if + will

[Iryn_]

Hello, dear forum users!

1. Is it Ok if I will use your laptop?

This sentence doesn't seem to be a conditional, so is it ok to use 'will' in it?
Will be grateful for explanations!

[Piscean]

It is not OK to use 'will' in that request.

[Iryn_]

so 'will' is never used after ''if'', doesn't matter whether it is a conditional or not?

That is not a logical rule to synthesise based on one sentence. One example is never enough for a rule. Rules are based on patterns of usage and often have exceptions. Will can be used after if when it is being used for persuasion/suasion:

Will is also possible after if in indirect questions:

I don't know if he is coming tomorrow,

Will is also possible after if in indirect questions:

I don't know if he is coming/will come tomorrow.

I agree. The "if" in that sentence is similar in meaning to "whether".

(1) If you will help me, I'll complete the task within three hours.
(2) If it will make you satisfied, I'll quit the job.

Do these sentences work?

[Piscean]

Both are possible.

However, as they are deviations from the norm, there should be a reason for using them. They are not simply optional variations that mean exactly the same as the standard forms.
