Computer Will Not Turn On ¶ 

When the power button is pressed, the computer does not turn on.

AC Adapter Issue ¶ 

If the computer is not powering on and it has been plugged into the charger, the charger (AC Adapter) may be broken. To see if the adapter is working correctly, start by performing a hard reset on your laptop (hold the power button down for 20 seconds and then try to power it back on by hitting the power button again 30 seconds later) without the AC adapter plugged in.

If the laptop is not turning on, you can try removing the computer's battery, plugging in the AC adapter back into the laptop and attempting to power it up again. If the power light turns on when you have the AC adapter plugged in, it most likely is not an issue with the adapter. However, if the power light does not turn on, your AC adapter may not be supplying enough voltage to your computer to power it up. If this is the case, try a different adapter that is compatible with your laptop.

Issues with RAM ¶ 

If you're attempting to turn on your laptop, the battery lights are coming on, and the screen is still blank and not responsive, there may be an issue with the RAM (random-access memory, a form of data storage that stores data and code currently being used). A reset of the RAM may be necessary at this point. Reset the RAM by releasing the RAM and then re-inserting it. Follow this guide to learn how to access the RAM. If that doesn't resolve the issue, the RAM will need to be replaced.

If the laptop can not start up because of stuck keys you must check each key to see if they are moving normally. If any keys behave differently it will need to be cleaned or replaced.

Damaged Power Adapter ¶ 

If the power adaptor is not functioning correctly, your computer may not be receiving enough power to charge.

To determine whether or not the power adapter is functioning correctly, check to see if the indicator light that is located on the power adapter is turned on when the computer is plugged in. If the light is not on, plug the power adapter into a different power outlet. If the light on the adapter still doesn’t turn on after you plug it into a new power outlet, the current power adapter is defective and will need to be replaced.

If the indicator light turns on, but the computer still doesn’t charge, test the voltage the power adapter is emitting with a multimeter. Place the positive multimeter lead inside the round female power socket and place the negative lead on the external portion of the socket body. If the read on the multimeter is not approximately 19.5V, the current power adapter is defective and will need to be replaced.
