-No Triple A titles

Requirement:
- RAM and SSD must be DIY upgradeable (not soldered)
- Battery life: min 4-5 hours of web surfing or office work. User removable battery a plus.
- Display: no size preference and no need high-end display.
- Weight: Nothing Above 3kg
- Brand: no preference but must be reliable and don't die within 2 years.
- Discreet GPU needed (GTX1050 or equivalent and above)

Was looking at Lenovo Y7000 2019, Y530, Y540 (LENXCIMB)
Skeptical about the battery life only.

Interested in Thinkpad T590 but not sure whether can run the games i play

Thanks in Advance.
