If your laptop won't power on, you can follow these troubleshooting steps:
Basic Checks
When the laptop is connected, look for any lights it has.
Battery:
In the case you can, it is recommended that you pull off the battery (if the one that is detachable is inside) and power the device using the AC adapter only.
You should replace the battery if the apparatus switches on when connected to the power source.
Cables and Connections:
As for the safety check, first examine the power cable, whether it has been damaged or not. If you have an option use another cable.
Hardware Reset
Hard Reset:
Pull the power adapter out and pull the battery out of the device.
This means you have to hold the power button down for the next 15-20 seconds to drain off any leftover power.
Unplug the battery and the power adapter and then plug it back again and switch on the device.
Display Issues
Check for Display:
The next thing is to listen for the fans or other sounds. If you hear them the laptop may be on while the display is off.
Perhaps, plug in another monitor to see if you obtain anything on it.
RAM and Peripherals
Remove Peripherals:
Unplug all other external appliances that the computer connects with (USB flash drive, external hard disk etc.) and start powering it on.
RAM Reseat:
If you feel alright, open the laptop and adjust the RAM sticks. Take them off and replace them with equal force.
Diagnostic Lights and Sounds
Check LED Indicators:
There should be blinking lights or a couple of error codes. The specific diagnostic code can be found in the laptop’s manual for proper configuration of the code.
Listen for Beeps:
In case the laptop produces some beep sound at start up, it is advisable to count the beeps. This can refer to certain problems with hardware in particular.
Last Resort
Boot in Safe Mode:
If you only noticed the logo but does it not want to start fully, press F8 or Shift + F8 while to get to Safe Mode.
Consult Support:
If none of these steps is effective there are a few more options available and in the end it is better to contact the manufacturer’s support or take the laptop to be repaired by a professional.
