Support NoPowerFix

NoPowerFix is for people who want to check their own phone, laptop or console, and for repair shops that test customer devices every day. Prices for new devices keep going up. A repair, or just knowing what is really wrong before you pay for one, keeps a good device working and out of the bin. Everything here is free and nothing tracks you.

How it works

The tests are free with no tracking.

A review or a coffee helps the next fix.

Why privacy comes first

Show more

Many free test sites run ad and analytics scripts. While your test runs, those scripts can read the device details like the model, screen, graphics chip, browser, language and time zone and send them to ad networks and data brokers. They use it to recognise the same device again. This is called device fingerprinting.

In a repair shop, that device usually belongs to a customer. A technician runs a quick keyboard or screen test and, without knowing it, shares the customer's device details with companies the customer never agreed to. Most people who test their own device at home don't know it happens either.

So we made NoPowerFix. One place where anyone, and any repair shop, can test a device without being tracked and without anything being shared.

Our promise

Privacy firstNo ads, no cookies, no analytics and no third-party scripts. The tests run on your own device, and the pages are locked by the browser's own security rules so they cannot send results anywhere. Support and sponsors never change that.
Less e-wasteEvery tool here is built to find the fault, so a device gets fixed instead of replaced. Our goal: less e-waste, greener Earth.
Free for everyoneEvery test is free, with no account and no paywall. When prices go up, a free first diagnosis matters most.

Why it needs support

Show more

We build and pay for everything here ourselves, next to our day to day repair work. Keeping it free and private still costs money:

  • The forum server and the domains - online every day, with no ads to pay for them.
  • Test hardware and bench equipment - meters, scope, thermal camera, programmers and test devices for every new check.
  • Bench time - every guide, panic code and repair case comes from real measurements on real boards.

Sponsors

Sponsors are welcome if they share our goal: repair tool and test equipment makers, parts suppliers and companies who want devices repaired instead of replaced.

What a sponsor gets

  • Your logo and a plain link on the tool pages or forum categories you choose, clearly labelled "Sponsor".
  • A mention in our published repair cases where your tool was really used on the bench - with the real readings.
  • A short monthly report: views of the pages your logo is on, as plain totals from the server - no tracker on the page.

Our rules - the privacy promise stays

  • No sponsor scripts, pixels or cookies. Your logo is a plain image hosted by us.
  • Discount codes instead of tracking links. You see what our visitors bought, not who they are.
  • Totals only - never anything about a single visitor or device.
  • No say over diagnoses. A sponsor's part is recommended only when the evidence points to it.
  • We turn down any sponsorship that needs tracking.

Sponsorships open soon. Interested? Write to contact@nopowerfix.com with your company and the tools or parts you make, and we'll let you know as soon as they start.

Free, private, built to keep devices alive

✓ No ads✓ No cookies✓ Nothing uploaded✓ Free

In 15 years at the bench we saw too many good devices go in the bin because nobody found the real fault. Our Hardware Specialist and Senior Repair Technicians built these tools so more devices get fixed instead of thrown away. If they helped you, a review helps the next person find them, and your support pays for the next fix.

> goal: Less e-waste · Greener Earth

We find the real fault before parts are replaced, so fewer working batteries, boards and devices end up as e-waste.
