I've never voided any warranty by IMMEDIATELY cloning the HDD to an SSD on all my new laptops and swapping onto the SSD.
Imagine buying a car and changing the wheels, then engine blows up and Toyota says AHA WARRANTY VOID.
If possible, I'd clone your HDD onto an SSD and then chucking the SSD in. Most SSDs will fit (they make them mostly the thinner height now)
I have. Ascent and an Asus laptop. It wasn't worth fighting them about it, and they mostly came to the party.
