Step‑by‑step checklist before you pay

1. Body, hinges and overall condition

• Outer body: Check top cover, bottom panel and palm rest in good light. Hairline scratches are normal; avoid deep cracks, missing pieces or bent edges.
• Hinges: Open and close the lid slowly at different angles. It should feel firm, without wobble, creaking or sudden loosening.
• Rubber feet & screws: Turn the laptop over – rubber feet should be present and screws should not be missing or loose.

2. Screen test: dead pixels, lines and brightness

• Physical damage: Check for cracks on the panel, pressure marks, white patches or light bleeding, especially on the edges and corners.
• Dead pixels / lines: Ask the shop to show plain white, black, red, green and blue backgrounds. Look for black dots, coloured dots or vertical/horizontal lines.
• Brightness & colours: Increase brightness to maximum and minimum. The screen should be evenly lit, readable, and not flicker.
• Touch (for touch models): On a touch‑screen laptop, swipe and tap around all corners to ensure the touch response is even across the display.

3. Keyboard and touchpad

• All keys: Type each key at least once (you can open Notepad). Ensure no key is sticking, double‑typing or not registering.
• Backlight (if present): Turn the room lights low and toggle the keyboard backlight keys to check if it works consistently.
• Touchpad: Move the cursor in circles and straight lines. Test left/right clicks and two‑finger scroll. The pointer should be smooth, without jumps.

4. Ports, webcam, speakers and Wi‑Fi

• USB & HDMI: Plug in a USB pen drive/mouse and an HDMI cable (if available). Confirm detection on screen and that display output works.
• Audio: Plug in headphones and check the 3.5mm jack. Also test speakers with a YouTube video or sample audio.
• Webcam & mic: Open the camera app and a video call app to check video and microphone clarity.
• Wi‑Fi & Bluetooth: Connect to the shop’s Wi‑Fi and pair a Bluetooth device if possible. This confirms wireless is working.

5. Battery health and charger

• Charger: Inspect the adapter and cable for cuts, exposed wire or loose pins. Confirm the charging pin fits snugly in the laptop.
• Charging behaviour: With the laptop on, plug in the charger and check that Windows shows “plugged in, charging” and the percentage increases after a few minutes.
• Battery health: Ask the technician to show you the battery health/status page in Windows or BIOS. Ideally, health should not be close to the end of life.

6. SSD health, RAM and basic performance

• SSD: Confirm that the storage type shown in Windows matches what you’re paying for (for example, 256GB SSD on models like the Dell Latitude 5400).
• Health / errors: Ask the shop to open the SSD information screen in Windows or BIOS that shows drive status/health; it should not show warning or failure messages.
• RAM: In the system information screen, confirm the RAM (for example, 8GB on these Latitude models) matches the invoice.
• Quick performance feel: Open a few browser tabs, a PDF and an Office document together to check that the system is comfortably responsive for your typical workload.

7. Windows activation, BIOS lock and security

• Windows activation: Go to the Windows activation settings and confirm it shows that Windows is activated with a valid licence.
• BIOS / admin lock: Ask the technician to enter the BIOS setup in front of you. There should not be any unknown password blocking entry.
• Company locks: Ensure there is no organisation or school account still linked that prevents you from resetting or reinstalling Windows later.

8. Matching serial numbers, warranty and invoice

• Serial number match: Note the serial number printed on the laptop’s bottom/under battery. Confirm it matches what is printed on the invoice.
• Warranty terms: Read the store’s warranty and return policy. You can also review Karthik Computers’ detailed warranty & returns page online.
• GST invoice: Ensure the invoice has GST details, laptop model, configuration, serial number and price clearly mentioned.
