| As a user, I find the laptop to be powerful and efficient in handling tasks. The CPU resources are adequate for multitasking. Gaming is possible but may require lower settings. The hard drive has enough storage space for files. The RAM is sufficient, but additional would be beneficial. The number of USB ports is suitable. The screen quality is impressive for office work, watching movies, and browsing YouTube. | ||

| I upgraded the memory from 8GB to 16GB and swapped the 1000GB HDD for a faster 500GB SSD. | ||
