How to troubleshoot laptop power failure issues?
Laptops offer you a greater flexibility to be a part of your day to day activities or business procedures even while traveling around. However, technical issues with laptops can be frustrating. Unlike desktops, it requires lot of expertise and technical assistance to resolve technical issues related to laptops. One of the main issues associated with laptops is the power failure. The first thing majority of people do is to replace the battery when the laptop does not turn on or the battery does not charge. Today, you find thousands of PC repair companies that do not have expertise in resolving technical issues and simply replace parts. While replacing laptops parts is easy, you need to spend lot of amount on things that can be solved easily. Here are detailed instructions on how to troubleshoot laptop power failure issues.
Be it a laptop or a desktop, there is a certain methodology to follow while troubleshooting an issue. You need to begin your troubleshooting steps from the starting point and then move on. There are different instances when laptops do not power on.
Laptop does not power on with the adapter as well as Battery
Consider an instance wherein your laptop does not turn on with the battery or the power adapter. Follow these steps in order to identify what is causing this issue. First of all, check the power cable and the power socket. Make sure that other components are working with that socket. If no electronic device is turning on, the issue is with the power wall. Secondly, examine the power cable to identify any cuts or cracks on the cable. If you find any cut on the wire, you need to replace the cable. Check out the led on the power brick. If the led on the brick is not glowing, then the power supply is not reaching the laptop. The next thing is to check the power led on the laptop. If the led is not working, wiggle the cable for loose contacts. If the power adapter turns on when you connect it to the wall and then turns off when you connect it to the laptop, there might be a short circuit. If everything is fine with power adapter, try borrowing another adapter from your friend to make sure that the issue is not with the power adapter.
Identifying defective component
Power failure issues often relate to other components. Any other component like memory, hard drive or a cd/dvd drive can cause a power failure. To identify the defective component, remove one component at a time and check the status. The most common component that can trigger a power failure is the memory stick. Remove each memory stick and check the status of the laptop. Put one memory stick in one memory slot and then swap it to see if the issue is with the memory slot or the memory stick. The next component to check is the cd/dvd drive. Remove the drive and turn on the laptop. If it turns on, replace the drive. In the same way, check out the hard drive. Remove other components like wireless cards, graphic cards and sound cards. Dissemble all components and check the status. If you are comfortable, remove the processor and the screen to narrow down the troubleshooting procedure. If the laptop does not turn on, the issue might be with the motherboard. If you know how to use a multimeter, check the power supply. If the power failure issue is caused by any of the component other than the motherboard, you can identify it by following these steps in a sequential order. If the issue is with the motherboard, you need a technical expert.
