Precision 7550 & Precision 7750 owner's thread

This is warning about latest BIOS 1.24.0, release date 09 Aug 2023.

If you use Dell dock WD19DC only one cable light is on so you do not get enough power etc.

I have done all know reset etc. tricks. Nothing helps. BIOS downgrade fails.


Best temporary fix is to use Thunderbolt dock WD19TB and use Dell Precision 7X50 own charger as extra power source.

Now the all external displays work again.


Last good known BIOS is version 1.23.1, release date 20 Jun 2023.


Here is more discussion if you are interested

The faulty BIOS file is still available for download.
