For you to effectively trouble shooting on your emachine problems arising from your computer, you need to understand the power circuit. This is how power circulates from the source through the system and completes the circuit. A perfect example of an emachine is your computer system.
The first thing you need to be keen at is if your emachine is working normally. Power transmission causes resistance and these results to production of heat. The fan therefore cools off the heat by enhancing air circulation.
But when the heat is too much, it means the resistance to the current has increased and hence the voltage might be affected. A malfunctioning fan will not cope with the hit produced and hence the system might stall.
The fun needs to be lubricated with the required lubricant to minimize friction, tear and wear. This is why you need to check all the resources concerned on power supply to your e machine for regular checks and repair routines.
You can proceed to test the power cables. This is done with the system turned off and the wall socket power connection cable out of socket. This is a precaution to avoid electric shock. The second place is the functionality of the drives. You may start with the hard drive; use a voltmeter for this. Proceed on to test other drivers such as the CD drives.
Other e machine components you need to check is the adapter. The adapter is the first causality in an event of power surge due to short circuit. During your routine check up, you might realize that one or two components are low.
To change the components, you must replace them with original components with the same model specifications. Always make sure you type in the right specification code online when you are shopping for it online.
