Lenovo B50-80 80EW05Q0PB (i5 5200) Motherboard Replacement: Compatibility with B50-70 LA-B092P (i3)

Hello, I lost my motherboard in the lenovo b50-80 80EW05Q0PB (i5 5200 model), I can't find any boards on the Polish market for the b50-80, hence my question whether the b50-70 motherboard will fit my model (e.g.: LA-B092P with i3) I do not want to hide that I want it to be as cheap as possible.

What is your original album?
What exactly does "fallen record" mean? Maybe repair will be cheaper than replacement.

What's the fault?
The plates are repaired.

After replacing the disk, the laptop did not start. I checked the power supply and the power supply - they were operational. After connecting to the power supply, the battery charging LED did not light, so I took the laptop to the computer service, today they called back and said that the elements on the board are burned out and should be replaced. They also said that I have to find the board on my own and they can replace it, after asking about the model of the motherboard in the laptop, the service technician said that he had already assembled the laptop and did not know (he said he would call back - he doubts that I will find out today). He just gave me the type of laptop. (laptop with i5-5200 without external graphics card)

You've come to a site not only for plate changers.
Such defects can be repaired without any problems.
Unless the record is actually burned in such a way that it is impossible, which I doubt.

Check what they will propose on another website.

they said the components on the board are burned out

- the replacement of damaged elements is precisely the repair.
There are cases when repair is impossible or unprofitable. But if the service does not use plate markings, it may already be alert ...

Both disc markings?

What specific elements did they say? because it smells terrible and incompetent to me, the album is not cheap, you can try to fix it

Description 80EW05Q0PB is the "hidden" description of the equipment of this laptop according to Lenovo
That is: 15.6 "TN (1366x768) HD LED, Anti glare / i5-5200U (5th gen cpu) / RAM 4GB / ... black housing Link_ specification

The MB description will be on the board itself> white letters.
The disc can be e.g.

- in the photo. Celeron 3215U (SR243)

LA-B092P rev.? (3.0) this one costs around $ 120-130 on ebay
- last bought, SoC + fell?, repair costs greater than the ebay disc
LA-B091P rev2.0 >> LENOVO_B50-80-8

What happened that you replaced the drive?
Which one did you put in?

Explain to the uninitiated the marking of this element?

SoC (processor + chipset + ... = all in one 1168pin BGA housing

system on chip (SoC)

Use generally accepted notations not slang straight from the land of burnt silicon.

SoC in slang appeared daaawno> when Intel invented the Bay Trail platform on the Atom.
I do not see anything offensive or iconoclastic about it.

Hello, I spoke to a service technician - he said that there was a burned hole in the board in the converters section and the tracks were also charred and the labor would be more than for a new laptop.
In that case, I repeat the question whether the Lenovo b50-80 EW laptop will fit the b50-70 laptop motherboard. I am asking because there is no motherboard for my laptop on the Polish market.

Write them (after reading the subtitles from your CD), you will get the answer if it matches b50-70.

This is what the burnout looks like, definitely irreparable?

It is impossible to judge from such a poor photo. First of all, first you need to clean the laminate from burns.

You have damage in circuits from tensions approx
PU401 SY8208BQNC + 3.3VALWP
PU402 SY8208CQNC + 5VALWP



From the picture, you can barely see how deep into the plate the burnout - hole. (as you provide), clean and take a photo.
Lift the glands and measure the resistance after them

No.

Why remove the coils?

Because nothing appears from the picture so far.
Maybe only the circuits went "into oblivion with a lot of smoke"?

If the PU402 is damaged and a (in fact) burned hole, look for new albums!

____________
From the photo. you can see that PU401 made "more smoke and bang".
Desolder it and measure resistance on strap_ pin.5 LDO or + 3VLP , there will be clarity on cost effectiveness and repair.
