In case your laptop is overheating and randomly switching off, then it might be because of dust or there may be a broken fan or dried thermal paste. A professional laptop fixing service may be a good solution before changing the device in order to have the root cause. The technicians will be able to wash internal parts, enhance the airflow, and verify hardware damage. Your processor and motherboard can also be caused damage due to overheating with time lapse and you should not disregard it. Every-year maintenance will go a long way into ensuring that your laptop serves longer and is consistent in its performance either at the office or when playing.
