BackSD card reader not working on Mesa Pro
28 Jun 2024
This information applies to Mesa Pro tablets.
Improperly inserting or removing a micro SD card can cause the SD card reader to stop working. For example, it may stop working if the SD card was
- Aligned incorrectly in the card tray.
- Inserted while the tablet was in sleep mode.
- Inserted after the tablet was shutdown but still connected to external power.
- Inserted after the tablet was shutdown but the red LED had not been off for 15 seconds.
To reset the SD card reader,
- Remove the external power. Then, power off the tablet.
- Wait for 15 seconds after the red LED turns off.
- Remove the battery door.
- Remove the battery pack by pulling up on the black tab on the battery pack.
- Use the card tray eject pin that came with your tablet to pop out the card tray.
- Make sure the SD card is properly aligned in the tray.
- Push the card tray back into place.
- Replace the battery pack and close the battery door.
- Power on the Mesa Pro tablet.
For more information on using a micro SD card, refer to the Mesa Pro User Manual.
Operating System Checks for Installed SD Card
To reduce power consumption, the operating system checks for a micro SD card each time the tablet is powered on, and if no card is detected, the operating system disables the SD card reader and the corresponding USB mass storage device in the Device Manager. This saves battery life by allowing the SD card reader (and other related USB resources) to go into a low power state.
To disable this feature, set the registry value:
[HKEY_LOCAL_MACHINE\SOFTWARE\Juniper Systems]
"DisableSDCheck"-dword:00000001
