overcharged laptop?

Hi all. I have a hp pavilion model 17-e117dx. The power needed for this laptop is 19.5V. I have a universal charger that can be switched from 10V to 20V. I had the computer charging at 19V while I was operating it. While in operation the universal charger was switched from 19V to 20V. This caused the computer to immediately shut down. Upon shut down I unpluged the charger and set it back to 19V. But now when I press the on button nothing works, and I mean nothing, nothing will start up, nothing. The power button blinks once every 6 seconds. Which I believe is a cpu failure. I have done a reset where you drain the power and I have removed the cmos battery on the motherboard, but with no luck... Any advice? Thank you in advance.

you need the oem charger

the only advice I can give is to get the original charger for the laptop. This is the only way to know if the failures is the result of you using a third party charger. You dont just look at volts when deciding on chargers, you also have to look at amps. You can burn out the power supply and the device may not function if not getting enough amperage.

generally when you are replacing the charger, you must make sure of the following

Make sure that the voltage matches as closely as possible.
Make sure that the new supply is rated to provide the same amperage or more.
Make sure that the connectors match, both in physical form and in polarity.
