Upgrading System Memory; Installing A Memory Module - HP t628 Troubleshooting Manual

Upgrading system memory

The memory socket on the system board is populated with one memory module. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory.
For proper system operation, the memory module must adhere to the following specifications:
● Industry-standard 204-pin
● Unbuffered non-ECC PC3L-12800 DDR3L-1600 MHz-compliant
● 1.35 volt DDR3L-SDRAM memory module
The thin client supports the following:
● 2 Gb and 4 Gb non-ECC memory technologies
● Single-sided and double-sided memory modules
● Memory modules constructed with x8 and x16 devices; memory modules constructed with x4 SDRAM
are not supported
NOTE: The system does not operate properly when a nonsupported memory module is installed.

Installing a memory module

CAUTION: You must unplug the power cord and wait approximately 30 seconds for the power to drain
before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to
the memory modules as long as the thin client is plugged into an active AC outlet. Adding or removing
memory modules while voltage is present may cause irreparable damage to the memory modules or system
board.
The memory module socket has gold-plated metal contacts. When upgrading the memory, it is important to
use a memory module with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the thin client or optional cards. Before beginning
the following procedures, be sure that you are discharged of static electricity by briefly touching a grounded
metal object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.
1. Remove/disengage any security devices that prohibit opening the thin client.
2. Remove all removable media, such as USB flash drives, from the thin client.
3. Turn off the thin client properly through the operating system, and then turn off any external devices.
4. Unplug the power cord from the AC outlet, and disconnect any external devices.

5. Remove the stand from the thin client.
6. Position the unit flat on a stable surface with the right side up.
7. Remove the thin client access panel. See
