How to Check a Refurbished Laptop Before Paying (Without Getting Scammed)

Editorial August 29, 2026 Buying Guides

Buying a refurbished laptop in Nairobi is a bit like buying a used car. On the outside, it looks clean and shiny. The seller promises it runs perfectly. But if you do not know what to look for under the hood, you could be walking away with a machine that dies in two weeks.

The good news is that you do not need to be a computer technician to protect yourself. You just need 10 minutes and a simple checklist.

If you are about to hand over your hard-earned money for a refurbished HP, Lenovo, or Dell, here is exactly how to test it before you pay.

1. Test the Battery (The Most Expensive Risk)

The battery is the most common failure point in refurbished laptops. Sellers often keep the laptop plugged in during the demo, hiding the fact that the battery holds almost no charge.

How to check it:

Unplug the laptop from the wall.
Click the battery icon in the bottom right corner of the screen.
Look for the estimated time remaining. If it says less than 2 hours on a full charge, the battery is dying.
Pro tip: Open Command Prompt (search "cmd" in the start menu), type powercfg /batteryreport, and press Enter. It will generate a report showing the battery's design capacity versus its current capacity. If the current capacity is less than 60% of the design capacity, you will need a new battery soon.

2. Check the Screen for "Dead Pixels" and Spots

Refurbished laptops often have subtle screen damage that is easy to miss in a bright shop.

How to check it:

Open a web browser and search for "Dead Pixel Test" or "White screen test".
Open a pure white webpage, then a pure black webpage.
Look closely at the white screen for any dark dots (dead pixels).
Look at the black screen for any bright white spots (pressure marks or screen bleeding).
Check the corners for any signs of white light leaking through. A little is normal, but a lot means the screen was pressed too hard in a bag.

3. Test Every Single Port

A broken USB port or a dead headphone jack is a major annoyance that sellers sometimes hide.

How to check it:

Bring a flash drive and plug it into every USB port. Make sure the computer recognizes it in "My Computer" or "This PC."
Plug in a pair of headphones and play a song on YouTube. Make sure you hear sound in both ears.
Check the HDMI port if you can (ask the seller to plug it into a monitor).
Wiggle the charger cable where it connects to the laptop. If the screen flickers or the charging light turns off, the charging port is loose.

4. Listen to the Fan

Older laptops collect dust. If the fan is clogged or broken, the laptop will overheat and shut down when you try to do real work.

How to check it:

Open YouTube and play a 4K video.
Let it run for 3 to 4 minutes.
Listen closely. You should hear the fan blowing air.
If it sounds like a grinding noise, or if the bottom of the laptop gets painfully hot to touch, the fan needs cleaning or replacing.

5. Confirm the Specs (Do Not Just Trust the Sticker)

Sellers sometimes put an "Intel Core i7" sticker on a laptop that actually has a Core i3 inside.

How to check it:

Right-click on "This PC" on your desktop and select "Properties."
Look at the processor (CPU) and the installed RAM (8GB, 16GB, etc.). Make sure it matches what the seller told you.
Open "Task Manager" (Ctrl + Shift + Esc), go to the "Performance" tab, and click on "Disk." It should say "SSD." If it says "HDD," do not buy it.

The Golden Rule: Ask for a Warranty

Even after doing all these checks, a laptop can fail next week. Parts wear out.

Never buy a refurbished laptop from a seller who does not offer a warranty. A reputable shop in Nairobi CBD will give you at least a three to six-month warranty. If they say "once you pay, it is yours," walk away. That is the biggest red flag in the market.
