Laptop keeps turning off why?
This could be due to overheating. If you have ever taken a laptop apart then you will have seen that on most laptops the cooling fan draws in air via a grill and then blows this air around the CPU and exhausts to the outside world again. This air is NOT circulated around the rest of laptop case to dissipate heat.
You can try these steps
1. Check your power chord, socket, UPS, everything that leads from the electrical network to your AC power adaptor, but don't forget to check your BIOS settings and software setup, because it's probably your adapter who's sensing an overload of power drain
2. In most cases, an overheating processor due to a build of internal dust is the cause for random reboots or turn offs.
3. AC power adaptor not able to sustain normal power needs (faulty power adaptor) - take care of the same items as those I mentioned at 1.
4. Especially with older laptops, the battery may overheat, simply due to internal battery fault, or charging levels.
5. If you have a new laptop, be sure to have all ventilation openings free, and when used on a desk, try not to allow full contact with the surface - use a book or two to keep the laptop above the desk and have some space beneath it.
