[Guide] Lenovo Ideapad S340 Laptop on Catalina

[Dr.Aequitas]

I installed tonight BCM94360CS2 and addon DDR + HDD, all works perfectly, wifi and bluetooth without driver !

Some pictures, many thanks !

Does this laptop has two M2 slots?
@larsonbids had an M2 A/E adapter and BCM94360CS2 wifi chip and put those in where the original wifi chip was on. Am I right?

That is correct, use the M2 A/E adapter for the BCM94360CS2 to replace the original Intel M2 wifi card. There is a second M2 NVME slot where the oem SSD resides. At least for the 15inch model, there is an empty SATA slot where you can install an additional 2.5inch drive.

One last question about wifi. Will this M2 A/E + BCM94360CS2 fit inside 14IWL? If so, I will order them both right away.

Check with Alexnov, he has the 14inch model. He asked about the wifi card on page 22 of this thread. Not sure if he bought one. From the pictures shared, it looks like a tight fit.

Depends on the model.. There are differences between the 15'' versions. For example I have a lot less space than others users with the 15' probably because of the cooling system on my version. But I could install this M2 A/E + BCM94360CS2 even there wasn't enough space. It just make a little more "thickness", but no problem at all. (Don't cut the last part of the adapter, as I did, otherwise it doesn't work properly).

Edit: This is my pc still with the original wifi. You can see that there is not enough place for the M2 A/E + BCM94360CS2 but I could install it. It just stay up that black part and make a little "thickness"

Btw, do someone have tested the battery? I didn't have the chance cause I always use the power.. How much does it last?

 

[ClashFarmer]

I never did a drain test but on the occasions that I have it unplugged, I still have about 70% left after about 3 hrs usage on OS X or Windows. I don't do anything that taxes the cpu, just general light stuff like surfing and typing docs.

I ordered M2 A/E + BCM94360CS2 cards from china yesterday. in about 26 days i can tell u if it fits a 14" model w/o dedicated gpu.

not yet, just waiting mine to be delivered. Although according to pictures of internals it should fit w/o any issues on models without dedicated graphics
