CAUTION: Regardless of the power-on state, voltage is always present on the system board as long as the system is plugged into an active AC outlet. You must disconnect the power cord to avoid damage to the internal components of the computer. 5. Remove the access panel. 6. Locate the battery and battery holder on the system board. NOTE: On some computer models, it may be necessary to remove an internal component to gain access to the battery. 7.
NOTE: After the battery has been replaced, use the following steps to complete this procedure. 8. Replace the access panel. 9. Plug in the computer and turn on power to the computer. 10. Reset the date and time, your passwords, and any special system setups using Computer Setup. 11. Lock any security devices that were disengaged when the access panel was removed.
B Statement of memory volatility The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business PCs. This chapter also provides general instructions for restoring nonvolatile memory that can contain personal data after the system has been powered off and the hard drive has been removed. HP Business PC products that use Intel®-based or AMD®-based system boards contain volatile DDR memory.
NOTE: A third-party application that, ideally, is U.S. Department of Defense (DOD) 5220.22-M approved can also be used. NOTE: The Secure Erase process will take a long time. The amount of time varies based on the hard drive capacity and write speed. 84 a. Enter the F10 BIOS Setup menu by powering on the system and pressing F10 as soon as the HP logo appears. b. Select the Security menu and scroll down to the Hard Drive Utilities menu. c. Select Secure Erase, and then select the desired drive. d.

SATA hard drives The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for HP personal computers have built-in drive failure prediction that warns the user or network administrator of an impending failure (crash) of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
D Linux technical notes HP offers a variety of Linux solutions for HP workstation customers: ● HP supports Ubuntu on some HP workstations. ● HP supports Red Hat Enterprise Linux (RHEL) on HP workstations. ● HP certifies and supports SUSE Linux Enterprise Desktop (SLED) on HP workstations. For Linux setup and restore procedures, see the user guide for your workstation at http://www.hp.com/ support/ workstation_manuals.
Audio All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions. The audio hardware provides basic playback and recording features. The ability to simultaneously play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.
NVIDIA graphics workstations Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA drivers for best results on Linux systems. HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder.
AMD graphics workstations Some workstation configurations include AMD graphics hardware. The supported Linux distributions should all have some “in-box” driver that supports the hardware well enough for the X server to run. Here are some of the Xorg drivers that may be loaded as the server starts: ● The Radeon in-box X driver will associate with some older GPUs. ● The fbdev or vesa X driver may activate for certain other cards.
