Why Assumptions Lead to Unnecessary Repairs
When a device suddenly stops working as expected, the instinct is to conclude it's broken. That conclusion is understandable — but it's often wrong. A significant portion of devices brought in for repair turn out to have no hardware fault at all. The culprit is usually something simpler: a drained battery, a misconfigured setting, a software conflict, or a loose cable.
Jumping straight to "it's broken" skips a short but valuable diagnostic process. Working through that process methodically doesn't require technical expertise — just a clear checklist and a few minutes of patience. The checklist below is organized to move from the fastest checks to progressively deeper ones, so you're not wasting time on advanced steps when the answer is a power button.
If you're also interested in getting more longevity from devices you already own, our guide on maintenance habits that extend device life covers practical upkeep strategies worth building into your routine.

What You'll Need to Work Through This Checklist
Most of these checks require nothing more than the device itself and a few minutes. A small number of steps benefit from basic accessories you likely already own.
Replacement charging cable
Used to isolate whether the original cable — rather than the device — is causing power or charging failures.
Another power outlet or extension cord
Allows you to rule out a dead wall socket or faulty power strip as the source of the problem.
Compressed air can
Useful for clearing dust from ports, vents, and keyboard gaps that can cause connectivity or overheating issues.
Manufacturer's support page or device manual
Provides model-specific forced-restart instructions and error code explanations that vary by device.
Don't Open the Device to Investigate
Unless you have specific repair training, opening a device casing to inspect internal components almost always causes more harm than it prevents. You may void any remaining warranty, damage ribbon cables or delicate connectors, or introduce static discharge damage. If the external checks in this checklist don't resolve the issue, consult a qualified technician rather than attempting internal inspection yourself.
Moisture Exposure Requires Extra Caution
If a device was exposed to liquid, do not attempt to charge or power it on until you are confident it has fully dried — typically at least 24–48 hours depending on exposure. Powering on a wet device can cause short circuits that create permanent damage where none existed before.
For devices with persistent connectivity issues, it's also worth running through our home network audit checklist — many apparent device problems actually originate with the router or modem, not the device itself.
After the Checklist: Next Steps
If you've worked through every item above and the problem persists, you've done something valuable: you've narrowed the problem down. You can now tell a technician exactly what you've already tried, which significantly speeds up professional diagnosis and reduces the chance of being charged for redundant checks.
Before assuming the device needs to be replaced entirely, consider whether the issue could stem from an app or software layer rather than hardware. Our article on auditing the apps on your devices is a useful companion step, especially if performance degraded gradually rather than failing all at once. Similarly, if you've been treating a high price tag as a proxy for reliability, common spec misconceptions is worth reading before you invest in a replacement.
Rule Out the Simple Causes First
The most common reason devices are unnecessarily replaced or sent for expensive repairs is skipping basic diagnostic steps. Power, cable, restart, and settings checks take under ten minutes and resolve the majority of problems that appear catastrophic at first. Always exhaust these options before concluding hardware damage.
Document what you observe during each check — unusual sounds, error messages, indicator lights, or specific conditions that trigger the problem. This information is genuinely useful to technicians and helps you avoid paying for a diagnostic you've already partially completed yourself.
