Our Computer Testing Process
Student computers want to give you an accurate grading to all of our refurbished IT Equipment so you know exactly what you are receiving. Please take a moment to browse through our grading system and also our testing procedure.
-
HDD (Hard Disk Drive) – We test to see if it can store up to its maximum capacity, and our diagnostic tools checks for errors
-
RAM (Memory) – Our diagnostic tools checks for errors.
-
Screen (if applicable) – Check for damaged pixels, cracks and damages
-
External Drive (if applicable) (CD/DVD Drive) – Test several CD and DVDs to check the drive functions correctly, and if the external drive is writable we also check this
-
Keyboard – Check to see if every key is working
-
Mouse – check to see its fully operational, Mouse pad left and right click
-
Wireless Card (if applicable) – Check that it connects to several wireless connections
-
USB Ports – Check to see if different hardware peripherals connect successfully
-
VGA Port (if applicable) – Check to see if an external monitor correctly works
-
Ethernet Port (if applicable) – Directly plug in a Ethernet cable to test the internet connection
-
Cleaning – This is done to a high standard with our professional equipment, please see below the grading process.
