To jump-start an HP computer, first ensure it's connected to a power source. Hold the power button for 10-15 seconds to reset it. Release, then press the button again to turn it on. If it doesn’t start, remove the battery (if removable), unplug, and hold the power button again to discharge residual power. Reattach the battery and power cord, then try turning it on. https://medium.com/@rashasavvy22/how-do-i-get-rid-of-hp-jumpstart-in-windows-10-ad6ea7ca11cc
