Laptop Testing and Diagnostics
Run the same style of checks our technicians perform on every Qevora device. Tests marked browser run right here; tests marked guided walk you through checks the browser can't perform directly. Nothing is uploaded — camera images and microphone recordings stay on your device.
01 Screen Test browser
Fill the screen with solid colours to spot dead pixels, backlight bleed, and uneven brightness. Press Esc, click, or tap to exit; use arrow keys to change colour.
Look for: pixels stuck on one colour, bright/dark patches, glow along the edges.
02 Keyboard Test browser
Click inside the keyboard area, then press every key. Working keys light up copper. Some system shortcuts may be captured by your operating system.
03 Mouse & Trackpad browser

Multi-touch gestures (two-finger scroll, pinch): try them on the scroll box — most register as scroll or zoom events.
04 Webcam Test browser
Your browser will ask permission. The preview and any capture stay on this device — nothing is uploaded.
Camera access: not requested
05 Microphone Test browser
Speak normally and watch the level meter. You can make a short recording and play it back — it never leaves your device.
Microphone access: not requested
06 Speaker Test browser
Play a tone through each channel. Set your volume to a comfortable level first.

07 Battery Check browser + guided
Checking browser battery support…
Full battery-health instructions
Windows: open Command Prompt and run powercfg /batteryreport, then open the saved HTML report. Compare Design Capacity with Full Charge Capacity.
macOS: hold Option and click the Apple menu → System Information → Power. Check Cycle Count and Condition.
08 Storage Check browser + guided
Checking browser storage estimate…
How to check drive health
Windows: Settings → System → Storage for capacity; run wmic diskdrive get status or the manufacturer's SSD tool for health.
macOS: Apple menu → About This Mac → Storage; use Disk Utility → First Aid to check for errors.
09 Memory (RAM) guided
Browsers can't fully test RAM — it needs operating-system tools. Safe options:
- Windows: search "Windows Memory Diagnostic", choose Restart now and check for problems.
- Mac: shut down, then hold D while powering on (Intel) or hold the power button → Options (Apple Silicon) to run Apple Diagnostics.
- Any PC: most BIOS/UEFI menus include a built-in memory diagnostic.
10 Network Test browser
For full download/upload speed, use a privacy-respecting test such as speed.cloudflare.com.
11 Bluetooth guided
Manual check: open your system Bluetooth settings, confirm the adapter turns on, and pair a device (phone, headphones, mouse).
12 Port Checklist guided
Plug a known-working device or cable into each port your laptop has and tick it off:
13 Touchscreen browser
If your laptop has a touchscreen, drag a finger across the whole grid. Every cell you touch turns copper — untouched cells may indicate dead zones.
14 Device Information browser
Everything your browser can safely report. Browsers cannot read serial numbers, exact hardware models, or full specifications — anyone claiming otherwise is guessing.
Test Summary
Mark each test above as Pass or Needs review, add notes, then save or print your report.
Disclaimer: browser-based diagnostics are a helpful first check but do not replace professional hardware inspection. Results depend on your browser, operating system, and permissions. Every laptop sold by Qevora Technologies additionally passes a full technician-run, multi-point hardware inspection.
