Hi:
Most likely your PC's M.2 slot is only PCIe Gen 3.0.
The Crucial P310 will work fine but it will not run at its maximum advertised read/write speeds from the Gen 3 slot.
The Crucial memory kit should work fine.
HP only has the service manual for the original 15-dy0xxx model series and chapter 1 indicates the maximum memory was 2 x 8 GB.
Maintenance and Service Guide HP 15 Laptop PC
You can run this command to confirm how much memory your notebook can support:
1. In the search box, search for cmd and click Run as administrator.
This will open the command prompt.
2. Once command prompt is opened, type wmic memphysical get maxcapacityEx and press the enter key.
There, it will show the maximum RAM capacity your PC's motherboard can support.
The capacity is shown as Kilobytes, so you have to convert it to Gigabytes by dividing the number provided in the report by 1,048,576.
Here's the link to the service teardown video for the original model series:
