Frequently Asked Questions

Models affected: TL7200, TL7400, TL7600, TL8400

The touch screen is either damaged, or the internal hardware is likely defective.

To run an initial check to your integrated touch thin client of whether the repair may be an in-warranty or out-of-warranty repair, check for cuts, faded areas or cracks across the screen, or damage to the system's plastic housing.  Any physical damage voids the system warranty.


There are several possible issues that can be checked:

  • Is internet service working (check with your internet provider)?
  • Is the wireless router working (powered on, ports working)?
  • Is the system within a reasonable distance of the wireless router?
  • Is software configured correctly? (network settings in OS, sw, drivers, router, wireless band [a/b/g/n/ac], passphrase)?
  • Is the wireless card properly connected and working?
  • Is your antenna properly connected (internal or external)?
  • Is the motherboard working properly?


  • Thinlabs PoE Computers can be powered by a POE 802.3at+ switch or midspan power injector.
  • A POE 802.3AT+ switch / injector can supply 30W or higher power per port.  
  • The device can be powered up to 100 meters (330 feet) using a CAT5e / CAT6 Ethernet cable.
  • Switches must be properly configured to provide the necessary power to a port. 
  • Check the peak capacity for an entire switch, which may be less than if all channels are plugged in.  


Configure your Cisco switch so that it properly works with Thinlabs Power over Ethernet (PoE) Computers (including, but not limited to,TL2530P, TL2640P, TL7600P, TL8510P, TL8610P models)..

Detailed Instructions

      Command or Action Purpose
    1 enable 

    Switch> enable

    Enables privileged EXEC mode - enter your password if prompted.


    2 configure terminal 

    Switch# configure terminal 

    Enters global configuration mode.

    3 interface interface-id 

    Switch(config)# interface gigabitethernet2/0/1 

    Specifies the physical port to be configured, and enters interface configuration mode.

    4 power inline {auto [max max-wattage] | never |static [max max-wattage]} 

    Switch(config-if)# power inline auto 

    Configures the PoE mode on the port.  Keywords and meanings:


      auto - Enables powered-device detection; if enough power is available, automatically allocates power to the PoE port after device detection (default setting).


      max max-wattage - limits the power allowed on the port; if no value is specified, the maximum is allowed.


      max max-wattage - limits the power allowed on the port; range is 4000 to 30000 mW; if no value is specified, the maximum is allowed.


      never - disables device detection, and disable power to the port.


    If a port has a Cisco powered device connected to it, do not use the power inline never command to configure the port. A false link-up can occur, placing the port into the error-disabled state.


      static - Enables powered-device detection; pre-allocate (reserve) power for a port before the switch discovers the powered device; the switch reserves power for this port even when no device is connected and guarantees that power will be provided upon device detection.

    The switch allocates power to a port configured in static mode before it allocates power to a port configured in auto mode.

    5 end 

    Switch(config-if)# end

    Returns to privileged EXEC mode.

    6 show power inline [interface-id | module switch-number] 

    Switch# show power inline 

    Displays PoE status for a switch or a switch stack, for the specified interface, or for a specified stack member.

    The module switch-number keywords are supported only on stacking-capable switches.

    7 copy running-config startup-config 

    Switch# copy running-config startup-config

    (Optional) saves your entries in the configuration file.

    Serial numbers of Thinlabs All-In-One Systems and Box Modules are 12 digits in length; serial numbers of ADITI Lithium Ion Batteries are 6 digits in length.

    Certification stickers with serial numbers are located on the back of box client modules.

    On integrated thin clients, there is a certification sticker on the back of the system;
    newer models also have a 2nd serial number sticker either on the left side bezel or on the bottom of the bezel.

    If the certification sticker has been destroyed, contact Thinlabs Support.


    • Turn the device OFF prior to cleaning.
    • Use any standard glass cleaner to clean the touchscreen - AVOID PRODUCTS CONTAINING AMMONIA.
    • DO NOT spray glass cleaner directly on the LCD - it could leak inside a non-sealed unit and cause damage.
    • Spray glass cleaner on a cloth / towel and then clean the touchscreen. A clean microfiber cloth can also be used.

    Increase the number of points to calibrate the touch screen using the Advanced properties of the touch screen software.


    - Check that the USB cable from the battery to the system is properly connected.
    - Check that the power meter icon is active on the lower right hand corner of the desktop.

    See the ADITI Mobile Computer for Medcarts Power Bank Guide for more information.


    This may be seen on systems with 2 GB RAM if the paging file is set to Disabled when installing resource-intensive applications. See the how-to document on Windows 7 - Memory Optimization for information on how to correct this error.
