How to check if your mac has still its original parts

I have a terrible doubt. Two weeks ago I split some juice on my mac. It happens, everyone knows.. But what it happens later was worse. I spoke with customer center and I booked an appointment on an apple center, but I didn't go because it was kind of far from my house, instead I went to Jump+ that have a kind of relationship that I haven't still understood with apple. Anyway, they opened my macbook and they asked me for 2600$ (the price of my laptop) because they said that it was impossible to repair. Anyway, two days later I went to a shop suggested by my teacher (I study IT) and they repaired my macbook for 25$.. big difference.. anyway, when I came back home I noticed that my screen seems different.I anticipated furthermore questions saying that I always check my laptop since I'm working on it everyday and I've never noticed any imperfection on the screen. My keyboard is sticky too, it makes sense because I split some juice on it but it wasn't that sticky. My question now is, is it possible to check if all the part of my mac are still the original that I bought less than 4 month ago? Because I have a doubt that is that in the first shop they could replace "by mistake" some part of my mac with other laptop part, maybe older part, because, as I said before, I always check all the part of my laptop everyday, and I guard it like it is the most precious thing in the world.. Thank you in advance, I'm looking forward for any suggestions

" is there any way to clean a keyboard of a 13' macbookpro bought in september 2014"

If the keys are operating correctly and it's just that their action is sticky there might be a way. However, since I've never laid hands on such a new machine I wouldn't be sure how the keys come off.

Here's a video referenced by iFixIt:

Make sure your keys work identically before trying this.

" I would like to know if it is possible that any part of my laptop was replaced without my knowledge, and if it was, how can I check it (like with a particular software or with a serial number"

If the computer is still operating you can look under the Apple: "About This Mac - More Info" and the serial number of the installed logic board will be on that window. Match that to the serial number embossed on the bottom of your MBP.

Otherwise it would take someone very versed in computer methodology to examine the inside of your computer carefully and under high magnification to determine if there was any tampering or modification.

Wow, you are getting scammed all over the place!

"2600$"

Totally nuts you could buy a new MBP for that.

"25$"

Equally nuts.

"Two weeks ago I split some juice on my mac"

No way that problem can be repaired for that price.

" it wasn't that sticky."

It will get stickier with time.

Also here's my standard blurb about a water/liquid incident:

"Whenever a liquid spill occurs the first thing that has to happen is the laptop should be shut down immediately. All power must be removed as soon as possible.

It is especially important that the battery be disconnected and removed.

No attempt should be made to start/restart the computer since this could potentially damage the logic board beyond all repair.

All affected parts must be removed from the laptop and carefully and closely inspected. Any involved area should be marked for special treatment.

Then all affected parts would be washed in deionized water and blown dry with compressed air. (In a water spill the deionized water is probably not as critical. Depends on the mineral content of the water.). An orange juice spill will be especially bad because of the sticky factor due to the sugars in the juice. The sugar will work it's way into the logic board and result in corrosion. The sugar is hydroscopic.

This is especially true of the large chips on the logic board. Liquid can wick under them and cause havoc for weeks if not months and years after the incident, depends on the liquid..

The logic board should then be placed in a drying/dehumidifing oven for at least two days. Longer depending on the spill.The keyboard is a separate matter

In fact for 25$ they didn't repair, they just checked for any problem in part like motherboard or HD. My question was slightly different. I would like to know if it is possible that any part of my laptop was replaced without my knowledge, and if it was, how can I check it (like with a particular software or with a serial number)?
Furthermore, I really appreciate your suggestion, and you are right, my keyboard get sticker but, is there any way to clean a keyboard of a 13' macbookpro bought in september 2014? Thank you in advance.
