_Auster_: Kinda hard to be precise, but if your specs are similar to mine (i5-5200U, also 8 GB RAM and Intel HD Graphics 5500), these games will likely work, although some need some tweaking to run at bearable speeds:
ABZÛ (kinda of a stretch; it was barely bearable at min settings); Atari Vault (only intro seems to lag; also includes ROMs); Bunny Swordmaster Story (old freeware); Celeste, Celeste Classic & Celeste Classic 2; Dreaming Sarah; Dusk Child; Dust: An Elysian Tail (optional challenges and a certain mandatory area are pretty laggy, tho); Etherborn (need to tweak graphics and it's still a bit laggy); Final Fantasy VII; FINAL FANTASY X/X-2 HD Remaster (if the game starts freezing or crashing, lower the resolution, since it has a bug with some graphic cards; otherwise you can be generous with the settings and it should still run well); Grey-Box Testing; Kimmy; Knight Club; LiEat; Mary Skelter: Nightmares; Metal Slug 3; Minecraft; Minoria (run kinda laggy on any settings, but fast enough to be playable); Mobile Light Force (aka Gunbird); Moero Chronicle; Momodora I, II, III and Reverie Under The Moonlight (II can be kinda laggy in some parts); Okami (runs well on medium graphic settings); One Strike; Phoenotopia [Flash version]; Portal; Rabi-Ribi; Saints Row: The Third; Songs for a Hero - A Lenda do Herói; Starbound (getting it to run well is a gamble; optimization mods could help); Tanglewood (also includes a ROM); The Deed; Unparallel; Va-11 Hall-A: Cyberpunk Bartender Action; Wake Up; Wishing Sarah (also includes a ROM); Wonder Boy in Monster World | Wonder Boy V: Monster World III (also includes a ROM); Micro Mages (also includes a ROM); Slipways Classic
There's also hundreds if not thousands of commercial games that can be emulated that likely work on such a laptop. And indies should often work too, although they're starting to get more resource-intensive. And bigger games from before 2010 (2015 at most) should work too.
going to try these games..
