Hi!
No music. No talking. Just work.
If you are taking your Acer Aspire V3-772G 7448 laptop apart be careful and wear an anti-static wrist band or use other anti-static device. If you need to change a LCD usually you don't have to take screen out of a laptop. You can leave it on a laptop and watch the last part of the video where I am taking LCD apart. If you need to change a keyboard, you don't have to take all bottom screws out. There are usually some marks, like a keyboard picture, on a case bottom. If you need to put a laptop back to work be aware of screws. They are different and you better remember or mark them somehow to insure that you will put them back in to a right place.
Some laptops I take apart first time, so don't be serious on my time and performance.
If something got broken - ooops, it's your fault.
Believe me, some parts in your laptop are already broken, you just don't see that.
Have fun and good luck!!
