Laptop won’t turn on? Work through this checklist before you panic

“Won’t turn on” covers several very different faults, and telling them apart is most of the diagnosis. Work through this in order.

Step 1: Is anything happening at all?

Press the power button and watch and listen carefully.

• No lights, no fan, no sound. No power reaching the board. Go to step 2.
• Lights come on, fan spins, but the screen stays black. The machine is running. This is likely a display fault, not a dead laptop. Go to step 4.
• It starts and then immediately turns off. Often a power or overheating fault. Go to step 5.
• You see a manufacturer logo and then an error. The hardware is largely fine; this is likely a software or drive problem, and your data is probably recoverable.

Step 2: Rule out the charger

Chargers fail far more often than laptops. Try a different socket. Check the cable for damage, especially where it meets the plug that goes into the laptop — that is where they break. If the charger has a light, is it on? If you can borrow a known-good charger of the right type, do.

Step 3: The drain

This genuinely fixes machines. Unplug the charger. If the battery is removable, take it out. Then hold the power button down for 30 seconds. Put it back together, plug it in, wait a minute, and try again. You are discharging residual power that can hold the board in a stuck state.

Step 4: Check the screen, not the laptop

Plug an external monitor or TV into the HDMI port. If a picture appears there, the laptop is working perfectly and you have a screen, backlight or cable fault — a much smaller job than you feared.

Step 5: Listen and feel

Beeping in a pattern is the machine telling you what is wrong. Very hot, or dusty vents, points at overheating. A clicking or grinding noise from an older laptop is a mechanical hard drive dying — in that case, stop. Every additional power-on can make data recovery harder. Bring it in as it is.

Step 6: Bring it to us

If none of the above worked, the fault is likely on the board — a power circuit, a charging IC, a failed component. That is exactly what our in-house workshop is for: we do micro-soldering and component-level fault finding on site in Radstock, rather than posting your laptop off to a third party and waiting.

Drop in any weekday between 8.30am and 5pm, and we will book it in and take a look.
