Component replacement procedures
NOTE: Details about your computer, including model, serial number, product key, and length of warranty,
are on the service label at the bottom of your computer. See Locating the product name, serial number,
product number, warranty information, and model number on page 27 for details.
This chapter provides removal and replacement procedures for Authorized Service Provider only parts.
There are as many as 56 screws that must be removed, replaced, and/or loosened when servicing
the Authorized Service Provider parts. Make special note of each screw size and location during removal
and replacement.
Unlocking the device and disabling Always On Remote Management (select HP
devices only)
HP Touchpoint Manager (HPTM) is a complete cloud-based solution for managing devices. For select HP
devices with the Windows operating system, the Always On Remote Management (AORM) feature is
automatically activated when HP Touchpoint Manager software is installed.
AORM can perform a secure BIOS level lock and can also securely erase internal drives (except for encrypted
self-encrypting drives). The HP Touchpoint Manager website (http://www.hptouchpointmanager.com)
provides access to the AORM lock feature. The device must be unlocked using an authorized PIN from the
same website before you can access HP Computer Setup and start the Windows operating system.
IMPORTANT: A service agent cannot retrieve the PIN from the HP Touchpoint Manager website. If a locked
device is returned for service, the agent must contact the customer to obtain the PIN to unlock the device. If a
PIN is not available, the entire system board must be replaced.
Before returning the device for service, be sure to unlock the device using the PIN from the HP Touchpoint
Manager website (http://www.hptouchpointmanager.com), and also disable the AORM feature in HP
Computer Setup.
