Originally I didn't possess an HP t610 and in Feb 2015 the pictures and information here had kindly been provided by Ken. In July 2017 I got hold of a t610 and updated some of the information on these pages.

Current data sheets on the range of models under the t610 name can be found on HP's website.

"The HP t610 Flexible Thin Clients deliver a true, PC-like experience for virtualized desktop environments. Built using AMD's new APU technology, the HP t610 combines dual core 64-bit processors and AMD HD 6320 graphics. Both thin clients feature DirectX 11 graphics support, DDR3-1600 RAM with up to 8 GB of capacity and AMD A55E Chipset with DVI-I and DisplayPort outputs for exceptional performance."

The t610 is available in a 'fatter' version - the t610 plus - and there is also mention of 'quad head' and 'six head' video options.

The t610 was launched by HP in February 2012.

depending on the exact model.

Power Supply

The unit requires a 19.5V supply. The supplied 65W PSU is rated at 19.5V 3.3A. The connector is a male coaxial connector. According to my micrometer the external diameter of the barrel is 7.4mm, the internal diameter 5mm. I don't what the size is of the recessed centre pin.

This style of PSU is also used by a range of HP laptops.

If you don't have an HP PSU/charger and are thinking of using a non-HP PSU see this page.

CPU

The CPU fitted to the t610 is from the first generation of AMD's Embedded G-Series System-on-Chip (SOC). It is a dual core CPU clocked at 1.65GHz.

Disassembly

This is straight forward and requires no tools. First remove the foot if fitted. Then, looking at the bottom cover of the t610 by the rear panel you will see the words LOCK, PUSH and UNLOCK moulded into the plastic. Push down on the PUSH tab and slide the cover to the rear and remove it.

Having done this you can then slide the side cover down about 5mm and then lift it away.

This reveals the metal screening cover. This has a couple of tabs that are lodged under the edge of the chassis at the left-hand (backpanel) side and a couple of tab/dimples which are an interference fit on the right-hand (front panel) side. Put your finger under the tab (arrowed), pull up, and then you should be able to lift the metal cover clear.

When you come to put it back together it is worth checking the tab at the top right (circled). This needs to be inside the internal metalwork, not outside. If it is outside then that corner is slightly proud but not enough to stop a ham-fisted person re-assembling the case and resulting in some small gaps in that corner. (That's the way mine came). It also takes a bit of brute force to get the plastic side cover on risking damage to the lugs on that as well.

Expansion

Click on the image of the circuit board for a larger version.

Flash: The Flash memory is easily replaceable. It's a DOM plugged into a SATA connector. There is also a standard 44-pin IDE connector (top left-hand corner) and another SATA connector. The detail of the two SATA sockets and the IDE socket are shown below.

In the photograph under the mods tab Ken has fitted a standard 2.5" drive to one of the SATA interfaces.

RAM: The RAM is standard 204-pin DDR3 1600MHz SODIMMs (PC3-12800). The two SODIMMs are on the rear of the motherboard and accessible via a removable panel. (See below). Whilst the t610 is capable of supporting 16GB of RAM, the amount you can actually use will depend on the operating system you have installed (e.g. With 32-bit Windows you don't see much over 3GB). [July 2017: Mario reported he'd successfully installed 16GB of RAM on his t610].

[January 2020] I tried out an 8GB 2Rx8 PC3L-12800S-11-13-F3 part from Hynix HMT41GS6BFR8A-PB which worked.

USB: There are two USB 2.0 ports on the front panel, two USB 2.0 on the rear and two USB 3.0 ports on the rear panel.

The retaining screws to hold the board in place are small. Luckily I found something suitable in my pot of screws from a dismembered laptop. At the time my crude estimate is was ~M1.

Subsequently I heard from Robert who wrote:

"M1.4x3 fits well however with my example I needed to add a home-made washer as the tiny screw head passed through the board mounting hole."

PCI-E: There is what appears to be a PCI-E expansion socket on the edge of the board. This is actually the connector that is used in the t610 Plus variant. The 'plus' version comes in a fatter housing and adds another serial port, parallel port and a half height PCI-E 4x slot. As the expansion socket is used to add a serial and a parallel port as well as a PCI-E 4x slot the connector can't be a standard PCI-E card slot. But all is not lost!

In November 2016 I received an email from Al who was considering using a t610 as the basis of a pfsense router.

"After studying info that I was able to find on the t610 (following traces of the riser card on a picture that I found on google) I came to the conclusion that it seems that the t610 actually has a pcie 4x compatible connector! So... after ordering an extender cable and cutting of the lanes 5-8 I was able to successfully connect a 4 port pcie 4x gigabit card to it."

i.e. The start of the expansion connector exactly matches the pin out of a PCI-E 4x connector. After pin 32 HP must use the remaining pins for the other features of the expansion unit. So, by connecting only those first 32 lines to another PCI-E socket, you can safely plug in and use any standard PCI-E expansion card.

Thank you Al for your detective work and sharing the outcome with us.

Note that a standard 44-pin cable connector is wider than the connector on the DOM. If you're using a cable to connect a hard drive you'll have to remove the plastic from the ends of the IDE socket in order to be able to plug in a cable.

Clear CMOS

HP's words for the procedure:

1. To clear the Setup or Power-On passwords if set, and clear any other settings, power down the computer and remove the AC power cord and the computer hood.
2. Locate the (blue/green) two pin password jumper on header E49 (labelled PSWD) and remove it.
3. With the AC power cord removed, wait 10 seconds until the unit AC power has drained out, then press the clear CMOS button. (This is typically a yellow push button, labelled CMOS).
4. Replace the hood and AC power cord and turn the computer on. The passwords are now cleared and all other user-configurable, nonvolatile memory settings are reset to their factory default values.
5. Re-enter the F10 setup utility.
6. Select File, Default Setup, Restore Factory Settings as Default. This will set the nonvolatile memory settings are reset to their factory default values.
7. Select File, Apply Defaults and Exit.
8. Shut down the computer, remove the AC power cord and place the (blue/green) jumper back on header E49. Replace the computer hood and power cord.

I'm not too sure who wrote this as at step 4 we have: ....nonvolatile memory settings are reset to their factory default values. So why go through steps 5-7 to repeat the process?

Fan connector

However we appear to have an anomaly here. My multimeter clearly shows the power pin sitting at +5V. Kenneth has used this connector to power a couple of fans. He reports:

I did initially try a 5v laptop fan and it blew out at extreme speed in about 3 seconds. The 12v fans I fitted subsequently appear to be operating at full speed.

If you have a t610 please can you let me know whether your t610 has +12V or +5V on this connector.

In November 2021 Robert reported he measured +5V on this pin on his t610 as did another correspondent in December 2021.
