In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific.

Let’s take a look at different failure scenarios.

Example 1. The computer is absolutely dead.

When you plug in the AC adapter and press on the power button, there are no signs of life at all. It appears to be dead.

What you can do ?

1. Make sure the wall outlet is working and the AC adapter is getting power from the outlet. Try another wall outlet.
2. Test the AC adapter, make sure the voltage output is correct. You can test the adapter with a voltmeter.
3. If the adapter is good, try reconnecting the battery. Remove the battery, wait for 1-2 minutes, plug in the adapter and try turning it on again.

If the adapter doesn’t pass the test with a voltmeter, replace it with a new one and test the computer. I always recommend buying an original replacement adapter from the manufacturer, not a generic one.

There could be more than one adapter available for your model.
The voltage output on your new adapter must be exactly the same as on the old one. The amperage, on the other hand, can be the same or higher.

If previous troubleshooting steps didn’t help, it’s possible your computer has a problem with the motherboard or DC power jack. In this case it’s necessary to disassemble the laptop and test the DC jack.

Example 2. The computer turns on and makes normal startup noises, the LED lights turn on but noting appears on

Difference between Intel Core i3, i5 and i7 in a Nutshell

To conclude in a statement, Core i7s are better than Core i5s, and Core i5s are better than Core i3s. The main reason here being performance. In general, Core i3 chips are found in budget PCs and low-end laptops. For a normal user who does browsing and watching videos, Core i3 works just fine. Core i3s have a low Cache size.

The mainstream or mid-range systems usually have i5. Systems with Core i5 are good for a moderate user and light gamer.
