The SSD is modular on this, so you can throw the tablet away and put the drive in an enclosure to get your data back. No need to mess with the board :-). Refer to this guide up to the point the back is off to remove the SSD. It may be mSATA or M.2 AHCI NGFF, so open it up and find out which enclosure you need. Dell used mSATA longer then any other vendor, so it’s harder to say without seeing the SSD visually.

If the device isn’t stone dead and the internal screen is dead, you can typically hook it up to an external display for recovery purposes but you need to change it to only use the external - which may be difficult with a display that’s not functioning correctly. Pull your stuff off externally if the SSD is modular instead of messing with the tablet.

If the tablet is completely dead, pull the SSD and don’t bother with the tablet.

If you do not see an SSD here, it’s soldered to the board :-(:

The other clue is size - 32-64GB is a soldered SSD red flag and it’s usually eMMC - which has lifespan issues compared to NAND flash.
