This information pertains to LabQuest 2.<\/h3>\n

If you have a LabQuest 3, see this article<\/a>.
\nIf you have an original LabQuest, see this article<\/a>.<\/p>\n<\/div>\n

If your LabQuest 2 partially turns on but doesn’t load the LabQuest 2 app all the way, it is possible to recover the unit with a special SD drive.<\/p>\n

The special SD card cannot<\/i> fix hardware or power problems. So, if you have problems getting a LabQuest 2 unit to turn on in general, the best place to start is I have trouble getting my LabQuest 2 to turn on\/start up. (flowchart)<\/a><\/p>\n

The special SD card can<\/i> fix software corruption problems that can’t be fixed with LabQuest 2 software corruption recovery instructions<\/a>. In particular, it can fix
\n–units that start up at least part way, regardless of whether or not they are running version 2.0-2.3.3 or 2.4 or newer.
\n–certain types of corruption that the USB drive can’t.<\/p>\n

Note: This SD card is very difficult to create. If you need one, contact Vernier Technical Support and we will send one to you.<\/p>\n

To use the SD card<\/b>
\n1. Turn LabQuest 2 off (remove the battery\/AC power if you can’t get it to turn off).
\n2. Put the SD card in the SD card slot on the top-right of the device (under the protective flap).
\n3. Plug the LabQuest into AC power (if it isn’t already) and reinsert the battery if you removed it.
\n4. Turn LabQuest 2 on.
\n5. Watch the scrolling text for a few minutes. When it is done, LabQuest 2 may instruct you to press the power button to turn it off, or it may turn off automatically.
\n6. Remove the SD card.
\n7. Turn LabQuest 2 on.
\nIf everything went well, it will prompt you to calibrate the screen.<\/p>\n

The SD cards will put an older version of the software on the LabQuest 2. After finishing with the above process, update the device normally by following the instructions at:
\nhttps:\/\/www.vernier.com\/support\/updates\/labquest\/labq2\/<\/a><\/p>\n

Do not connect the SD card to a Windows computer.<\/b> If you do plug the SD drive into a Windows computer, Windows will advise that the disk is corrupted and offer to “fix” it for you. Select no.<\/p>","protected":false},"excerpt":{"rendered":"
