DIGITAL SIGNAGE FAIL – OVERHEATING ISSUES

DIGITAL SIGNAGE FAIL – OVERHEATING ISSUES
Posted: November 11, 2019 at 12:15 pm   /   by   /   comments (0)

I was walking past a retail store and saw a screen with a message I’ve never seen before. The message had:

POST ERROR

System Temperature

900-System Temperature.

The System BIOS has detected you machine was previously shut down to avoid overheating. Overheating may occur if the cooling vents are blocked or the operating temperature exceeds the system specifications. The machine should return to normal operation once the situation is resolved.

Press ENTER to continue.

FAIL FEATURES

  • Content is not displaying
  • Error message is displaying
  • Need to press the Enter key to continue

SUGGESTIONS/RECOMMENDATIONS

  • It’s hard to say whether there was actually any issues with ventilation or air flow as we couldn’t inspect the back. Our assumption is the screen is enclosed and there are no air vents to blow out the hot air.
  • We’ve never used HP digital signage screens but we’re assuming it has an internal media player. Since the error is POST boot this message will be displayed until someone presses the ENTER key. The only problem is if it’s in an enclosure access to the USB port to plug in the keyboard might be challenging and it’s not something the local retail staff is able to do.  For some of our retail stores, we do provide instruction on how to recover the system in the event of such failures
  • Unfortunately, since the issue is related to BIOS there are no remote tools that support staff can use to remotely connect to the device. Some screens and digital players do have a WOL feature where you can remotely restart the unit but in this particular case, it may end up on the same screen
  • We suggest the retail store or digital signage network provider to look at the root cause of the issue and see if maybe even the fans on the digital screen are working. It’s possible the fans are not functioning as expected due to dust accumulating over the year and has caused the fan to be faulty
  • There are remote power smart plugs that can be potentially used to restart the units but as mentioned above, the root cause of the issue needs to be investigated
