Where can I find my jumpers

@ericbaah what kind of jumpers? What are you trying to accomplish? If you are trying to reset your CMOS via jumpers, I am sorry to tell you that you can't. The HP EliteBook 840 G5 does not have a CMOS jumper. You can try to reset the CMOS by disconnecting the CMOS battery. You can also try to reset it by using the keyboard shortcut,. Turn off the computer and plug in the AC adapter. Next press and hold the Windows key + V and the Power button for at least two seconds before releasing the power button, but continue holding the keys until the CMOS reset screen or beeping sounds appear.
