My professional 3D designing software require higher system configurations, so upgrading is mandatory for me.

Current System configurations:

HP 240

Intel core i3 processor

256 GB SSD

512 GB HDD

4 GB LPDDR4 RAM

New Battery

(Battery life:

Approx 2+ hrs battery backup on continuous heavy tasks with full screen brightness including background running applications)

Having 2 dedicated RAM slots so it's very easy to upgrade RAM size. Although 4 GB is sufficient for efficient day to day tasks.
