How To Check Whether Your Laptop power Supply Works

You've bought this really hot laptop, maybe a few years old. It is a few years but works just fine. You are browsing the net on your laptop one day when the thing just goes off without even the hint of a warning.Even when you unplug the laptop and pull the battery out, the power still stays shut. You even go as far as to press the power power button which usually shows blue lights in front of the mouse pad.  Instead, power button flashes the dreaded  red light four straight times making you wonder "Well, what is going on hear?. Well, Bad News! Your laptop power supply could be dead. But  not to worry! I will show how to check whether your laptop power supply works or not! 

Things you'll need for this exercise:

• OHM meter(Buy one at your nearest electronics store)
• A/C Adapter
• Power Supply

 Plug A/C adapter into a Wall Socket

 Plug  a/c adapter into a wall socket. Make sure the power cable is properly inserted into the power supply brick.

Locate the A/C adapter's voltage level. This usually located at the bottom of the power brick 

Place The Red Wire at OHM Meter

• On the OHM meter, place the red wire at the slot  with a + sign(positive). Then plug the black wire in the - slot(negative). Make sure the plastic handles are off when you slot in the the wire ends.
• Set the Ohm meter to DCV(Direct Current Voltage) and make sure the voltage on the Ohm is set higher than that of the voltage listed on the power supply.the recommended level for the Ohm is 50.
• Place the tip of the black conductor on the outside of the a/c  adapter.
• Place the tip o0f the red conductor inside the a/c adapter.
• Look at the needle reading to check whether power is being supplied.  If the voltage needle lands on the marking near the listed voltage, it means there is power in your laptop, if not, then it means the power supply is dead. Meaning it is time to send your laptop to the repair shop.
