Troubleshooting

Laptop Won't Turn On? 6 Things To Try First

By Dwane Thompson, Owner· August 6, 2026·7 min read

About a third of the “dead” laptops that come through our door aren't dead. Here's the checklist we'd run through with you on the phone, at no charge, in the order that finds the problem fastest.

Start with the boring one: is it actually getting power?

This finds the fault more often than anything else on this list, and it costs you nothing but a minute.

Unplug the charger from the wall and from the laptop. Plug the charger into a different outlet — one you have tested with something else, like a lamp. Plug it back into the laptop and look at the charging light.

No light at all? The problem is the charger, the outlet, or the charging port. Those are three very different repairs and the light tells you which direction to look.

Light comes on, laptop still won't start? Power is reaching the machine. Move to the next step.

One thing worth knowing: chargers fail far more often than laptops do. The cable flexes every time the lid opens, and it eventually breaks inside the insulation where you cannot see it. If you can borrow a charger of the same wattage from someone, that single test rules out about a quarter of no-boot calls.

Do a hard reset — properly

This clears the machine's residual power state, and it fixes more laptops than people expect.

  1. Unplug the charger.
  2. If the battery comes out, take it out. Most modern laptops it does not — skip to step 3.
  3. Hold the power button down for a full 30 seconds. Not five. Thirty. Count it.
  4. Put the battery back, plug the charger in, and press power normally.

People almost always undercount that hold. Thirty seconds feels absurdly long when you're standing there holding a button. Do it anyway.

Listen and feel before you look

Press power and put your ear near the machine.

Rule out the screen with a second display

If you have a monitor or a TV with an HDMI port, plug the laptop into it and press power. Many laptops need you to press the display-switch key too — usually Fn plus F4, F5 or F8, marked with a little screen icon.

If a picture appears on the TV, your laptop works. The fault is the screen, the backlight, or the cable that runs through the hinge. That last one is common on machines that have been opened and closed a few thousand times, and it is a considerably cheaper repair than a motherboard.

Take the removable stuff out

USB drives, SD cards, docking stations, external hard drives, a phone left plugged in overnight. A faulty peripheral can hold a laptop in a state where it will not complete startup, and a stuck SD card is a genuinely common culprit.

Strip it down to bare laptop and charger, then try again.

Check whether it's the drive, not the laptop

If the machine powers on, shows the manufacturer logo, then hangs, restarts in a loop, or lands on a black screen with a cursor — the hardware is probably fine and the problem is the drive or the operating system.

Stop here if your files matter. If you suspect the drive and there is anything on it you cannot replace — photos, business records, a dissertation — do not keep restarting it, and do not let anyone reinstall Windows on it. Every additional boot writes to a drive that may be failing, and a reinstall can overwrite the exact data you are trying to save. Power it down and leave it off until someone has imaged the drive.

When it's worth bringing in

Call us at 915-886-7098 and describe what you found. Most of the time we can tell you on the phone which of the above it is, roughly what it costs, and whether it's worth fixing at all.

Bring it in if: you got no charging light and a known-good charger didn't help; you heard beeps; the external monitor showed nothing; or you think it's the drive and your files matter.

We're at 816 Franklin St A in Anthony, right on the state line — see drive times from your town. The diagnostic is $99.95 and it comes off the repair if you go ahead. If we can't fix it, you don't pay for the repair attempt.

Common questions

My laptop has power but the screen is black. Is it the screen or the laptop?

Shine a bright light at an angle across the screen while it's on. If you can faintly see a desktop or a logo, the display panel is fine and the backlight has failed — usually a cheaper repair. If the screen stays truly black but the fan spins and the keyboard lights up, it's more likely a graphics or motherboard fault.

How much does it cost to find out what's wrong?

Our diagnostic is $99.95, paid up front, and it's credited toward the repair if you go ahead. That covers a technician actually opening the machine and testing it rather than guessing.

Is it worth repairing an older laptop?

Sometimes yes, often no — and we'll tell you which before you spend anything. As a rough rule, if the repair costs more than half what an equivalent refurbished machine costs, we'll say so and show you what's on our shelf instead.
