In case you don't speak Russian the search field is in the upper right corner of the website- the one with "поиск" (search) button underneath. Type in the model you're looking for and proceed from there.

In case you can't find the manual you're looking for feel free to file a request in this thread. Someone may be able to help you with that.
Re: Service Manuals for Acer notebooks (repository)
I know they just were released, but if anyone is able to get the service manual for the M5-481TG or (alternatively) M5-581TG, I would appreciate it!
For that matter, if the 7741G series manual is available, that'd be great too. I believe I have a faulty touchpad and even though other manuals are similar, it'd be nice to have instructions for that specific model.
