Troubleshooting Laptop Power Issues

A laptop cannot function without adequate power, and laptop power issues can sometimes be difficult to diagnose and to fix. Here are a few of the most common power issues and a few ways to troubleshoot them.

Laptop Won’t Power Up

When a laptop won’t power up, the problem usually lies in the AC adapter or battery. Try running the laptop from just the battery, then try running it with the AC adapter with the battery removed. If possible, try borrowing a working battery or AC adapter from a friend or at a repair shop. Replace the adapter or battery as necessary.

Battery Doesn’t Charge

The operating system usually gives an indication as to whether the battery is charging. When the battery does not charge correctly, even when plugged in, the problem is usually a faulty AC adapter or a bad DC jack. If replacing the AC adapter does not solve the problem, the DC jack (where the AC adapter plugs into the laptop) may need to be repaired. Take the laptop to a professional repair technician.

Laptop Turns Itself Off

If your laptop is turning itself off at random moments, there could be a few causes. Over-voltage or under-voltage from the AC adapter can sometimes cause the computer to turn off, but the most common cause is overheating. When the laptop becomes overheated, it will often power down to save components from being damaged. Use a can of compressed air to blow as much dust and debris from the laptop’s vents as possible, and check that the cooling fan is working correctly.

These are the most common power issues you will encounter with any laptop. Hopefully, the troubleshooting tips above will help you to diagnose and fix the problems you encounter and get your laptop back up and running properly. If you have tried the troubleshooting tips above and are still having problems, it is a good idea to take your laptop to a qualified repair technician.
