    First of all, you have done all the normal steps that a consumer can do as you even tried an external monitor which is all that you can do, so its not the screen! I'm afraid that your problems are due and is a sign of the internal main 3.3V power supply not working and powering your laptop on, as its either its Super IO and other related circuitries that have issues, which could be one of its capacitors has deteriorated and burnt out or the actual Super IO has shortened and all this needs diagnosing and replacing, which can only be done by an experienced technician that has all the proper tools (even a thermal gun) and all the proper equipment, so take it to them and don't try and do anything else as you will damage your laptop and be up for bigger repair costs if you attempt this yourself. Good luck and hope this helps you out as I know that these sorts of problems are a pain and very annoying.

    It might also be the issue with battery, charger or power outlet.   Try to use the charger in a different room on a different power outlet.  Try to bypass the surge protector and connect it directly to power outlet.    Try to use an alternative charger if possible.    Try to turn on the computer without the charger and check it  ( as long as the battery is not drained out )  


    I am really sorry for the inconvenience..   Let us do the basic steps one more time and check..


    Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:

    Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and – sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

    If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 
     
    If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.  After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn’t bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it’s internal statistics.

    Connect all the cables back and restart the computer.  


    While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   
     
    It might also be the issue with battery, charger or power outlet.   Try to use the charger in a different room on a different power outlet.  Try to bypass the surge protector and connect it directly to power outlet.    Try to use an alternative charger if possible.    Try to turn on the computer without the charger and check it  ( as long as the battery is not drained out )  

    Try windows x 
    go to device manager 
    expand Battery
    right click on all the items below battery – uninstall 
    Restart the computer 
     
    It should work fine.. 

    Please let us know whether you are able to turn on the computer.
