|
|
|
|
| activity indicator (dot on 7 segment display) does not flash |
|
|

|
| then the LINDY CPU Switch is not receiving data from the |

| screen and this type of auto power down occurs then the |
|
|
|
|
| screen becomes blank. Keyboard and mouse data is |
|
|
|
|
| captured by the menu process and so is not sent to the |
|
|
|
|
| computer to cause it to wake up. The operation therefore |
|

| appears to ‘hang’. To restore the video under these |

|

|
|
|
|
| avoid leaving the menu on the screen if you have a PC that |
|
|
|
|
| exhibits this anomaly. |
