New HP Notebook Won't Turn on

[VINTAGESYNN]

Hello all! I’m in a rut My HP notebook won’t stay on. I start it up, it gets to the login screen, I login in with my credentials and once it’s on my desktop it shuts off after a few seconds. I believe it’s some type of virus because unfortunately before it started all of this acting up I was being shown ads for tons of different virus protection after my free trial ran out but didn’t purchase any. Smh it also will not hold charge without the charger cable plugged in. NOW WE’RE HERE. HELPPPPPP
