My laptop switches off after few seconds of power

If your Acer TravelMate turns on and shuts off within seconds, it’s usually a power or hardware issue. Start by disconnecting the charger and removing the battery (if possible), then hold the power button for 20–30 seconds to reset. Try booting with only the charger connected. Reseat the RAM and check for loose components. Overheating or dust buildup can also cause a malfunction—clean the vents and fan. Once it stays on, you can use a system optimizer tool to scan for system issues and improve stability. If the issue persists, please consider having it examined by a professional.
