Rather than paying an expert to do the needful for you, you can certainly do so on your own since troubleshooting issues related to laptop chargers is not quite rocket science. Read on to obtain acquainted with an easy step-by-step process to know if your laptop charger is faulty:
Ensure your charger is plugged correctly into an outlet. You can even check perhaps the outlet is functioning needlessly to say by plugging in another charger or appliance. The troubleshooting process is only going to work if your charger is receiving power using this outlet.
Try to run your laptop directly from your charger. This is one of the finest ways to check if your laptop power supply is working or not. If your laptop doesn’t run entirely on the charger, it will probably possess some problem. Additionally, laptop chargers can power a notebook without charging the battery. This is also a sign of a fault. Remember to hold back for some minutes to see any result after connecting your laptop to the charger.
If your charger passed the previous troubleshooting step, try to charge it after turning off the laptop power. Many faulty laptop chargers can successfully charge a notebook, that will be turned off, but fail to do the exact same when the laptop is turned on. The shortcoming of a notebook charger to power a tool while charging the battery is really a sign that there surely is a snag.
Take your laptop battery out and check it carefully. Closely inspect all elements of the battery and battery-case in your laptop. A corrosion or leakage of any sort in and round the laptop charger adapter battery-case or on the surface of the battery may indicate a notebook charge fault. Get your laptop power supply, charger, and battery tested by a professional as soon as possible in such a scenario.
Testing laptop chargers with the help of a voltmeter is the simplest way to check their effectiveness and functionality. When you have got an Alternating Current (AC) charger, you will have to adjust the voltmeter reading to 25 VAC. All AC chargers are generally tested only at that value. Bring the probes touching the contacts and study the reading on the voltmeter. If the voltmeter doesn’t indicate any reading at all, your laptop charger is almost’dead.’
If you have a Direct Current (DC) charger, you will have to adjust your voltmeter to 25 VDC. Bring the probes touching the contacts (as above) and check again. No matter what the reading on the charger is, it should read one or more volt more whenever you perform the test. If it does not show a reading higher by a margin of one or more volt, simply switch the probes and perform the test again. All laptop chargers must certanly be clean before they’re tested with a voltmeter. You are able to remove dust and corrosion with the help of a cotton swab.
