| Overall, the laptop offers good CPU resources for multitasking. It may struggle with high-end gaming due to lack of discrete graphics. The 500GB HDD provides ample storage for files. 4GB RAM is sufficient for office programs and movie watching. The Full HD IPS display offers crisp visuals. | ||

| I upgraded the memory from 4GB to 16GB and swapped out the 500GB HDD for a 1TB SSD | ||
