Scanned NM-C741 Rev. 1.0

 

Scanned NM-C711 Rev: 1.0

Motherboards that go in the same case:

Lenovo IdeaPad S145-15IWL NM-C121 (Intel "i" 8th gen. DIS & UMA & RAM)
Lenovo IdeaPad V15-IIL NM-C711 (Intel "i" 10th gen. UMA & RAM)
Lenovo IdeaPad 3 15IML05 NM-C781 (Intel Celeron & "i" 10th gen. DIS or UMA & RAM)
Lenovo IdeaPad 15IIL05 NM-D031 (Intel "i" 10th gen. DIS & UMA & RAM)

 

Scanned NM-C511 Rev: 1.0

Check if it fits with this list of boards:

Lenovo IdeaPad S145-15IWL ----- NM-C121 (Intel "i" 8th gen. DIS & UMA & RAM)
Lenovo IdeaPad V15-IIL --------- NM-C711 (Intel "i" 10th gen. UMA & RAM)
Lenovo IdeaPad 15IIL05 --------- NM-D031 (Intel "i" 10th gen. DIS & UMA & RAM)
Lenovo IdeaPad 3 15IML05 ------ NM-C781 (Intel celeron & "i" 10th gen. DIS or UMA & RAM)

I checked.
All of these are blue from the list.
And NM-C171, NM-C511 and NM-D151 is green.
And they are AMD
NM-C171 is crap that heats A6 A9 etc..
NM-C511 seems to be Ryzen 3rd gen. and the AMD A300.
NM-D151 seems to be also Ryzen 3rd gen. and the AMD A300.
Which A300 found itself in the transition from the A series to Ryzen
But it is exactly the same board shape as the ones on the list.
Even the connectors match.

 

Scanned NM-C362 Rev: 1.0

The ITE chip is burned.
You can see it from the plane.
But that doesn't bother the picture.
Otherwise, it is a common problem with Lenovo when the DC connector is broken.
And when the ID pin touches the positive pin.

Scanned LA-L502P Rev: 1A

My bios chip was XM25RU128CH
Since my programmer (TL866II Plus) didn't have it listed, I read it as any chip that runs at 1.8V.
I chose the 25Q128FW.
I loaded that same content into the 25Q128FW and tested it on the motherboard.
The board worked as if nothing had happened.
