Symptoms
- Pressing power button does nothing
- No lights, no fan noise, no sound
- Screen stays black even plugged in
- Charging light doesn't come on
Likely causes
- CommonBattery fully depleted and charger not seatedA drained battery with a loose charger connection looks identical to a dead laptop.
- CommonFaulty or dead charger/adapterAdapters fail internally with no visible sign.
- PossibleBad wall outlet or power stripEasy to overlook and easy to test.
- PossibleBattery failure (won't hold or accept charge)Older batteries can die outright.
- Less commonInternal hardware fault (motherboard, power circuit)More likely after a drop, spill, or power surge.
What to do
- Plug the charger into a different, known-working outlet and confirm the connector is fully seated at both ends.
- Look for any light on the charger brick or near the laptop's charging port; no light at all points to the charger or outlet.
- Try a different charging cable or adapter if you have access to one, since cables fail more often than the laptop itself.
- Hold the power button down for 15–30 seconds with the charger connected to force a hardware reset.
- If the laptop has a removable battery, remove it, then try powering on with only the charger connected.
- Check for any swelling under the case or a warm/bulging trackpad, which changes the safety picture.
- Leave it plugged in and charging untouched for 30–60 minutes in case the battery was too deep-drained to respond immediately.
