3 Routine care, SATA drive guidelines, and
disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
IMPORTANT: When the computer is plugged into an AC power source, voltage is always applied to the
system board. You must disconnect the power cord from the power source before opening the computer to
prevent system board or component damage.
Electrostatic discharge information
A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device
exposed to electrostatic discharge (ESD) might not appear to be aected at all and can work perfectly
throughout a normal cycle. The device might function normally for a while, but it has been degraded in the
internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
IMPORTANT: To prevent damage to the device when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
Note the following:
● Dierent activities generate dierent amounts of static electricity.
● Static electricity increases as humidity decreases.

Packing PCBs in foam-lined box
Multiple electric components can be packaged together in plastic tubes, trays, or polystyrene foam.
NOTE: As little as 700 V can degrade a product.
Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
sensitivity. The following packaging and grounding precautions are necessary to prevent static electricity
damage to electronic components.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.

Utilities Hard Drive Utilities
● Save/Restore MBR of System Hard Drive
NOTE: Windows 10 systems are generally not formatted to include an MBR. Instead they use GUID
Partition Table (GPT) format, which better supports large hard drives.
Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR
gets changed, the user will be prompted to restore the MBR. Default is Disabled.
The MBR contains information needed to successfully boot from a disk and to access the data stored
on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the
MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also
allows you to recover the last known good MBR, should changes to the MBR be detected when the
system is restarted.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is Disabled.
Only appears if all of the following conditions are true:
– MBR security is enabled
– A backup copy of the MBR has been previously saved
– The current bootable disk is the same disk from which the backup copy was saved
IMPORTANT: Restoring a previously saved MBR after a disk utility or operating system has
modied the MBR, may cause the data on the disk to become inaccessible. Only restore a previously
saved MBR if you are condent that the current bootable disk's MBR has been corrupted or infected
with a virus.
● Save/Restore GPT of System Hard Drive
Enabling this feature saves the GUID Partition Table (GPT) of the system hard drive. If the GPT is
subsequently changed, the user is prompted to choose whether to restore GPT.
● DriveLock/Automatic DriveLock
Allows you to assign or modify a master or user password for hard drives. When this feature is
enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither is
successfully entered, the hard drive will remain inaccessible until one of the passwords is
successfully provided during a subsequent cold-boot sequence.
NOTE: This selection appears only when at least one drive that supports the DriveLock feature is
