Troubleshooting Guide HP t520 Flexible Thin Client

Populating the SODIMM socket
There is one SODIMM socket on the system board. The socket is labeled DIMM1.
Installing SODIMM
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain
before adding or removing the memory module. Regardless of the power-on state, voltage is always
supplied to the memory module as long as the thin client is plugged into an active AC outlet. Adding or
removing the memory module while voltage is present may cause irreparable damage to the memory
module 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. 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. Disconnect the power cord from the power outlet, and disconnect any external devices.
CAUTION: You must disconnect 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.
5. Remove the thin client from the stand and lay the thin client down with the right side up.
6. Remove the thin client access panel. See
Removing and replacing the access panel on page 9.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system components
to cool before you touch them.
