1. Does this laptop come with a 1 RAM slot or 2? Would the warranty be void if i upgrade RAM?

2. Does the Laptop come with an additional slot for upgrading SDD? Can i add another 512GB SSD?

Here is the Service Manual:

Manual 

So right now you have a pair of 4 gb DDR4-2666 SO-DIMM modules and even though the Manual says a pair of eight gig is the max its actually a pair of 16s for 32 gigs total as the max. You are allowed to upgrade memory and storage and retain the warranty. 

As for storage, you have a 512 gig PCIe/NVME M.2 SSD. There is no other place to put a storage disk (hard drive or SSD). The only way to have more internal storage is to install a larger PCIe/NVME M.2 SSD. You could use an SD card for additional raw storage of files if you wish. 

Post back with any more questions and please accept as solution if this is the info you needed.
