In many cases, it is very difficult to detect surges and power spikes. If you come across situation like laptop is not booting up shutting down randomly and abruptly then it might be due to the faulty power adapter. If this happens, you should diagnose and fix it as soon as possible. This is because it may damage the laptop components. What you can do is that run the laptop on battery and check whether the problem persists or not. If your laptop runs properly on the battery, then the cause of the problem is the faulty adapter.

If there is any wear, tear, cracks or other physical defects in the transformer on the laptop adapter it may cause the problem. A worn or torn adapter cable may also be the reason.

Run your thumb and forefinger along the length of adapter cable between the power surge box and the adapter tip, as well as between the power surge box and the pronged end that plugs into a wall outlet. Pinch the cable as you go until you see the indicator light flash on and off. This is the location of the short.
If the laptop adapter has some fault it might not be able to charge the laptop battery. Even it can reduce the effective battery life of the battery. Power surges created by a faulty adapter may make the battery charge unevenly which is also very harmful for the battery. If you find the battery is charging but can not run the batter for long it could be the result of faulty battery. On the other hand, if you find that the laptop battery is not charging at all, it is the problem of the faulty adapter.

Locate the frayed ends of the wires and twist them together to re-establish the connection. Make sure the ends of the wires are securely twisted together.
