Free laptop tools — FAQ
Are these laptop tools really free?
Yes. Every tool on this page is free to use and needs no signup or account. You do not have to buy anything from us to use them.
Where do the prices in the tools come from?
Shop prices come from NN Laptops's own current price list for laptops and parts in stock at our Hafeez Center shop. Repair, battery and upgrade costs are estimates based on our workshop's usual prices — the final price is confirmed after we check your laptop. They are a fair reference point, not a nationwide average.
Which tool should I use before buying a used laptop?
Start with the Used Laptop Deal Checker if you have an ad from OLX, Facebook or WhatsApp. Then use the Laptop Price Checker to compare the price, the Battery Health Analyzer to read the battery report, and the Windows 11 Compatibility Checker for older laptops.
Which tool helps if my laptop is broken?
Use the Laptop Repair Diagnosis to find the likely fault and a rough cost, then the Repair or Replace Calculator to see if the repair is worth it. For a broken screen, the Laptop Screen Finder decodes the panel part number so you get the right one.
Do the tools store my data?
Most tools run in your browser and do not save what you type. A few tools (such as the AI Laptop Finder and Repair Diagnosis) send your answers to our server to build the result; we do not ask for your name or phone number to use them.
Can I talk to a person instead?
Yes. WhatsApp 0314 4000131 or visit Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore (10:00 AM – 10:00 PM, closed Sunday).
Want a second opinion from a person?
Send a screenshot of any tool result on WhatsApp and we will reply. Every laptop we sell is tested and comes with a 30-day check warranty, with nationwide courier delivery.
