Laptop randomly turns off ? Soluation:

This is often due to:

• AC power adaptor sensing an overload of power drain
• Overheating processor due to a build of internal dust (clogged fan)
• AC power adaptor not able to sustain normal power needs (faulty power adaptor)
• Battery overheating, due to internal battery fault, or charging levels
• Intermittent short circuit or open connection (check condition of power leads)

On older Laptops, the most common reason is poor cooling. Try going somewhere air-conditioned and see if that helps. Inspect the areas near the internal cooling fan; see if there is a build up of dust fibres. Easy way to check this; with the unit running, feel the flow of air from the cooling outlet(s) - is the airflow very low? If yes, and the unit is at normal operation temperature, this may indicate the internal cooling system is partially clogged.
