R5-571tg-78g8 WD Black SN750 reporting it's using only 1 lane?

WCM5683

Can someone please help me to understand why my R5-571tg-78g8 which the manual nor any reps will tell you that it has a capable m.2 nvme ssd bootable slot on the mobo, is running only at x1 lane speed however? I've read somewhere it's because you have to switch in your BIOS from sata to nvme however my laptop is so old there isn't an option for that and I don't look for any future BIOS updates to come out at all much less to include this. Is there anything else I can do? It is still benchmarking at almost 900Mb/s however it's potential is 3100 up to x4 lanes. If I could even get just x2 lanes in that old laptop I'd be happier than now. This has been reported using WD SSD software as well as crystal disk info software. 

Thanks in advance.

Specs on the Aspire R5-571TG says the SSD support is SATA, so if you get an NVMe to work at all it's going to be at SATA speeds.

Hi,
Yes, you are going to get that sort of speed with WD SN750 because roughly the same speed others getting with this SSD in their laptops as well, unfortunately, nothing can be done to improve the speed.

Thanks for both the answers. I assumed it would run at least at 2 lanes, however. Could/would anyone know if in fact, I installed an m.2 b-keyed sata would run any faster at all? I'm again not a gamer so the results of it (on my benchmarks I have with crystal disk is 896 random which I'll take 8-9x faster than the HDD all day long, it was about what you've posted above with cpuuserbenchmark) which are SATA speeds correctly but still 5x faster. It beat buying a new laptop for sure since I am a Professor and was teaching from home for over a year. I was just thinking I could possibly get x2 lanes out of the SATA which would make a difference if I installed one but wondered if anyone could tell me for certain? 

One more. If you were to buy a new laptop for business and have the option of:
1. Dell, HP, Acer, Macbook (dual booted with windows) which brand
2. Gen 10 or Gen 11 and i5 or i7?
3. Would you just get the smallest NVMe it offered and then install the SN750 once in hand or?
