The Power Provide convert's your common household present into low DC voltage utilized by the laptop or computer. When this component fails,there is basically no activity going on wih your computer.Keep in mind to do the very easy troubleshooting 1st.Inspect the Energy Supply for any harm.Double-Check all connections.
Learning how to check your energy provide and how to replace it when necessary can be a life saver if you're a computer buff or in company with the trusted PC.Do not take for granted the easy pleasure of turning on your PC and every thing works just fine.
We turned on 1 of our computers recently and in about one hour,it just re-booted itself.And it continued carrying out so about 10 occasions a day till we found out the energy provide was the culprit.Items to appear for when your power provide is going negative or just dies on you are the following.
NO Energy TO THE Computer system
Here you should 1st check the wall outlet for power by connecting a different device such as a radio or lamp to be certain energy is present.If the computer is connected through a surge protector,check it as well.
If the wall out has power,check the energy cable going to the PC to see if AC voltage is producing its way to the technique unit.Do this with the use of a multimeter.
If there is power,you will have to open the PC and check for energy from the energy supply to the motherboard.
When working with a multimeter to check voltage,be sure you have a beneficial ground for the black lead of the multimeter.
RE-BOOTING Issues
One primary trouble you may possibly face with an ailing Energy Provide is that it may possibly re-boot the computer with out any warning.All information and facts is lost and it appears as though this occurs at the worst doable time.
Booting errors when the laptop or computer initially start's up is one more indicator of this component going on the blink.
Power DISTRIBUTION Difficulties
When the power provide begins to fail,you may obtain power at one device and not one other.For example,the Tough Drive may get energy but the CDROM Drive has absolutely nothing at all.
A different headache with would cause re-booting is the intermittent power going to the drives or the motherboard itself.Follow the steps below to check your energy supply should really you knowledge some of the above troubles.
CHECKING THE Energy Provide
If the wall outlet,and the power cord are great,make positive the connection at the motherboard is secure.Then you may possibly have to face the truth that the power provide itself is negative.If you have a Multimeter you can test the energy provide output prior to buying a new one.Just follow these actions.
Turn off the PC,but do not unplug it,open the system unit. Set the multimeter to read DC volts in the subsequent range higher than 12 volts.Locate a power connector similair to the tough drive,or cdrom drive connector that is unused and turn on the PC.
You can also unplug a drive connector and use it as properly.Turn on the PC and insert the BLACK probe into the energy connector on one of the BLACK wires.Touch the RED probe to the YELLOW wire on the power connector.
The multimeter reading should really be +12 volts Now touch the RED probe to the RED wire and the reading should be +5 volts.If no readings or diverse readings occured,you'll have to replace the energy provide.If the readings had been right,you must check the P8 or P9 connectors at the motherboard. These connectors may also be named P4 and P5.To check these connectors,carry out the following...
Insert the BLACK probe into P8 at one of the BLACK wires. Insert the RED probe into the P8 connector at the RED wire. The reading on the multimeter will need to be +5 volts
Check the energy going to the Motherboard connections by inserting the RED probe into P8 at the YELLOW wire and you should certainly get +12 volts.Leave the BLACK wire touching the black wire at the P8 connector.Check the BLUE wire and the reading must be a -12 volts.
Now move the BLACK probe to the BLACK wire on the P9 connector.Test the WHITE wire by inserting the RED probe and the reading should certainly be -five volts.Check the RED wires on the P9 connector and you will need to get +five volts on every single red wire.You won't get specifically five or 12 volts but the readings will be pretty close, such as 5.02 volts.
If the Energy Supply is a couple of volts off,in either direction,such as when the RED wire must be reading -5 volts but it reads -8 volts,or if there are no readings,replace the energy supply.
DO NOT remove the energy provide from the method unit case when performing these tests.DO NOT perform these tests if you do not feel comfy.Be confident to get rid of any and all electrical static construct-up from your clothes and body Just before touching any parts inside the method unit.And In no way open the energy supply case for any reason,considering that high voltage may perhaps be present.
