WYSE S10 Power up problem

I have a Wyse S10. The power LED comes on yellow immediatley when the power is plugged into the unit. Pressing it will do nothing, light stays on.  Holding it for 3 or so seconds will turn off the light until you release and it comes back on yellow.  Mean while there is nothing displayed on the monitor, just black, the monitor actually gois into power save mode beucase of no signal.  The original keyboard lights do not come on, Ie Numlock, and do not if you press num or caps on.  A USB bluetooth device was plugged into the USB port that has a blue LED on it for power, and that blue LED comes on on that so the USB's have power.

THe unit worled fine for a couple of weeks, then litterally when I got up to get coffee, came back, unit was in this state. 

Tried power button resets several times G Key with original keyboard, even tried unplugging the firmware chip ( yup, resorting to old fashoned meathods) and still same, nothing on monitor, no signal, as if nothing is even plugged into it.

Any Ideas?

    Tried the powering thing. Several ways.. Still comes on right away with the green light on terminal. No go. Tried another power supply as well. I tried to get a hold of WYSE to see if I could get the firmware chip, as nothing is even displayed on the monitor, the monitor doesnt even think a device is connected and goes to power save mode.

    The WYSE keyboard lights do not blink, nor numlock, caps lock etc so nothing after unit is just pwoered on, or after unit is powerd for a while.. seems like a dud!

Replacing C38 will fix the problem. It's a Lytics SMD Capacitor 47uF/10.3V.

    If you cannot find SMD buy a regular leaded one. Normally we buy caps from Also check You can use 47uF / 16V or 25V.

I solved this by unplugging all peripherals, leaving the LAN cable plugged in and cycling power to the S30.

    More specifically, I have a DVI connection to my monitor, and if the power to the T10 is removed, it won't boot up after power is re-connected if the DVI connector is plugged in. Unplug DVI, boot T10 and then re-connect DVI.



I had this problem on some S10 models, thought it's a hardware problem, I sent them immediately to Wyse support.

I've seen similar issues with the S30 after Power Generator tests, some terminals will have the Orange light on.

I read somewhere, ages ago, that this is a problem with the AC adapter. Simply pull the power cable out of the AC adapter and wait until the Green LED completely goes out.

Not until the power completely drains, will the terminal come back on.

It seems ridiculous, but even if the terminal is in a socket whose power is switched off, that little green LED on the AC adapter will stay lit up. We send someone in once a month, after the power generator testing to fix this. We tried recording which terminals were faulting, but soon discovered that different ones did not power back on each month.

WYSE S10 thin clients; we are hearing from users that when they hit the power button, the unit restarts instead. This behavior is also present using the gui interface. Not all units are doing this, but we...

Check in the BIOS, "Fireport" is the password. I cant remember if the power button behavior is set there or in the wnos.ini file.

You can check the config generator on to see if the command is in there for the wnos.ini

The Wyse S10s require a firmware update to connect to Windows Server 2008. This is due to lack of support for RDP 6.1.

The only way to get this update is to contact Wyse. However, I have deployed it on numerous clients (our entire base is S10s) and had great success.

Hard Reset

Youch, thats a pickle!!

Basically, because the terminal is in loopback mode when in the OS, you would need to find an up to date .i2d file, and for the S10, then try and re-image it with Wyse Simple Imager. This will use PXE and DHCP option tags to grab the device, and push an image to it.

Make sure PXE is first in the boot order in the BIOS, people often forget this!!

All the software you need (apart from the i2d file) is available from the Wyse website. When it comes to the i2d file, you will need to contact Wyse directly to get hold of this.
