Hello there!
I need some help on identifying this components on the motherboard!
The component market with 1 is missing, and the 2, 3, 4 and 5 appear to be bad. Maybe its a good idea to replace them? What are your thoughts?
All comments are more than welcome!! thank you!
(I forgot to mention, laptop does not power on)

Carles, looks like they already have been replaced. All of them are part of the 15V boost regulator circuit. Since you do not know what happened to the board before and what components were soldered on it, I'd replace it.
#1 Reference Designator C3880 is a 0.1UF 25V 10% X5R Capacitor in a 0402 package
#2 Reference Designator C3891 is a 10UF 25V 10% X5R Capacitor in a 0805 package
#3 Reference Designator C3898 is a 4.7UF 50V 10% X7R Capacitor in a 1206 package
#4 Reference Designator C3896 is a 4.7UF 50V 10% X7R Capacitor in a 1206 package
#5 Reference Designator C3897 is a 4.7UF 50V 10% X7R Capacitor in a 1206 package

Hello!!
First of all thank you for your time and your help....you are an eminence of ifixit!!
Allright, I will be ordering the components, but if you say they have already been replaced, maybe some other component is blowing them?
What you think about LT3957 or DFLS230L? Could they be the problem?
Thank you!!
LT3957 could have gotten some damage, but you do not know since you do not know what happened to the board. I'd clean the board and replace the parts properly, then re-evaluate.
Okay thank you su much!!
Let's see what happens!
