WIFI Replacement BCM94330U (BCM4330 Part# 20200050) Not detected in Yoga 13 Type 20175

2019-04-29, 8:26 AM

According to Yoga 13 service manual, AzureWave's BCM4330, Part number 20200050 is a replacement for WIFI card and should work. 

 


I believe even though it is listed as a compatible part in Yoga 13 maintenance manual, it is probably not whitelisted in System BIOS and probably that is why it is not detected at all



Yoga 13 has been working well for ast 5 years (part from the keyboard hiccups). I have also managed to update its SSD to 1TB and it seems to be working. I use it for my work (software development) and I need a 5Ghz WIFI replacement card for which I imported one 

 

 

Please help!. I am running the latest BIOS from lenovo site. If I need to downgrade the BIOS or do something with the BIOS, then I would like to do that in order to make the card work. It is listed as a suppored card and it does not seem to work. Please help. 

 

P.S: I have attached Ideapad yoga Maintenance manual as reference too!

I've bought the same card for wife's Yoga 13, I will try replacing it in a few days and will let you know.

Unfortunately no luck. Looks like it is blacklisted in bios. Probably an error in service manual where it states that it is compatible. Well, at least I've cleaned the laptop from the dust and repasted. If you have access to appropriate hardware you can flash modded bios with disabled blacklist.

I do not have access to the apropriate hardware. Do you mean SPI flash programmer or something?

Are you aware of such a guide which details both hardware/software & steps to flash a modded firmware?

 

I tried Insyde utility as well as Intel Flash utility.The "Error  28" does not allow me to move forward with the flashing as far as intel flash utility is concerned. Insyde utility wont let me flash unsigned bios.

 

So will appreciate if you can point me towards a resource that details preise procedure so that I do not mess it up!

 

Thanks

Yep, you need SPI programmer, Error 28 means write protected bios.

This thread will help you if you want to take a risk.
