							11 HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside
the operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.
NOTE:To start BIOS on a convertible computer, your computer must be in notebook mode and you must
use the keyboard attached to your tablet. The on-screen keyboard, which displays in tablet mode, cannot
access BIOS.

●
Computers or tablets with keyboards:
▲
Turn on or restart the computer, quickly press esc.
●
Tablets without keyboards:
▲
Turn on or restart the tablet, and then quickly hold down the volume down button.
- or -
Turn on or restart the tablet, and then quickly hold down the Windows button.
2.Press or tap f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a.Connected USB drive
NOTE:To download the HP PC Hardware Diagnostics (UEFI) tool to a USB drive, see 
Downloading

							12 Specifications
Input power
The power information in this section may be helpful if you plan to travel internationally with the computer.
The computer operates on DC power, which can be supplied by an AC or a DC power source. The AC power
source must be rated at 100–240 V, 50–60 Hz. Although the computer can be powered from a standalone DC
power source, it should be powered only with an AC adapter or a DC power source supplied and approved by
HP for use with this computer.
The computer can operate on DC power within the following specifications.
Input Power Rating
Operating voltage and current 19.5 V dc @ 2.31 A – 45 W
19.5 V dc @ 3.33 A – 65 W
NOTE:This product is designed for IT power systems in Norway with phase-to-phase voltage not exceeding
240 V rms.
NOTE:The computer operating voltage and current can be found on the system regulatory label.

							13 Electrostatic Discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for example,
the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components.
To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions:
●
If removal or installation instructions direct you to unplug the computer, first be sure that it is properly
grounded.
●
Keep components in their electrostatic-safe containers until you are ready to install them.
●
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●
Use nonmagnetic tools.
●
Before handling components, discharge static electricity by touching an unpainted metal surface.
●
If you remove a component, place it in an electrostatic-safe container.
