Re: Lenovo Y50 replacement motherboard compatibility

Hi kobeml , 

 

Welcome to the Community Forums. 

 

Would you have the machine number to identify details of your model? 

Compatible FRU is can be checked from the hardware manual from the support website.

 

Likewise parts lookup page (using your serial number) would also enlist those that came with your machine and likewise those parts that are compatible with your machine if available. 

 

Update us soon as convenient.

 

Regards

Re: Lenovo Y50 replacement motherboard compatibility

Is Machine Number the same as Machine Type Model? If so, it's 80EJCTO.

In the hardware manual my motherboard PN is found in one of the rows in Table 4 Parts List with the following entries for each column:

No. : 4

FRU :C Y50-70 W8S 4700 DIS 2G (Y50-70/Y50-80/
FRU no. :Y50-70 Touch/Y50-80 Touch)
CRU ID. :5B20F78873

That row does not tell me anything useful at all.
The table contains also parts for Y40-70 so how I am supposed to use that table to deduce compatibility?

 

Parts lookup page gave me this for my PN:

MB C Y50-70 W8S 4700 DIS 2G   (5B20F78873) is compatible with the following machines:

Hi kobeml , 

 

Greetings. 

 

Machine Type Model 80EJCTO , I believe that full machine number description is listed on the parts lookup page when you place in your serial number (you can also privately message me your serial number if you like but just not include it on the post).  Hardware manual would enlist general parts for the models as same reason we would like a specific machine number to work on. 

 

MB part number 5b20f78873 is compatible with machine number 59425943 , 59425944 , 59423621 , 59426255 , 59421810 , 20378  (anyone of this maybe yours) when I checked it with lenovo encompass

 

However 5B20G57048 would not show any details on compatible machine numbers and is cheaper but do not have the same description / specs on the original motherboard.  Other reseller claims end of life and is compatible to machine number : 59444129 59444486 59445775 59446045 

 

Regards

 

*** Edit note for update ***

 

For your LenovoY50-70  Machine number 59426157 

5B20F78873 MB C Y50-70 W8S 4700 DIS 2G SYSTEM BOARDS
No Substitutes , No on Most current service PN information either.

 

Other systemboards don't share all features . On similar cases  some devices may fail to be recognized by the board.

Suggestions would be getting unique OEM part 5B20F78873  MB C Y50-70 W8S 4700 DIS 2G SYSTEM BOARDS .

 

Challenge here is most are EOL (end of line) as some resellers like ebay may still have like here but not sure in your location/ country. 

 

Alternatively , closest option if exact board is not available would be getting boards for machine number 59425943 , 59425944 , 59423621 , 59426255 , 59421810 or compatible with those.

 

I tried finding soft substitution for MB 5B20F78873 from parts look up :

Part number 5B20F78820 MBCY50-70W8S4700DIS2G Substitution Type SOFT

Re: Lenovo Y50 replacement motherboard compatibility

If you could give me list of compatible replacement PNs for 5b20f78873, that would be great. Or some other designation which can be found on the motherboard sticker, that would work too.

 

Thank you.

Hi kobeml , 

 

Closest substitution for MB 5B20F78873 from parts look up :

Part number 5B20F78820 MBCY50-70W8S4700DIS2G Substitution Type SOFT  

 

Checked on machine number 59425943 , 59425944 , 59423621 , 59426255 , 59421810 uses same 5B20F78873 .

If resellers would say they tested functionality with any of these machine numbers then it would be good alternates but always check on return options to be on the safe side.

 

For OEM products , it would be useful to use FRU / Part numbers for searches to avoid incompatibility issues.

 

Hope this help answer your query. 

 

Regards
