Please make sure you have done the appropriate uninstall reinstall of drivers and updates for drivers for power sources. Stop usimg so many different kinds! Btw a huge issue you are potentially having is you are looking at the wrong number. Stop looking at the wattage.

Your laptop should have the 4 something ampere output, not the 3.3 or the 3.6 or whatever. So it should read on the back, 19.3 v 4.(?) A out put
