Greetings, and thanks so much for all the effort you've put forth into this software. I have a Dell Precision 7540 8FC8 laptop on my bench.

Hello,

If anyone has BIOS dump from dell precision 7540 touchscreen version?

I have similiar issue with Dell precision 7540. I swapped non-touch screen to touch screen from 7530(as they are same),touch screen does not work and Windows does not see touchscreen device....

Hi. My laptop stopped booting after Windows Update tried to upgrade the bios to version 1.32.0.
The regular Dell bios recovery doesn't work (both autorecovery and the "hold ctrl+esc while inserting the power" methods), it just crashes and reboots if I use newer versions of the bios and downgrade to older versions isn't allowed.
If someone can help me correcting the bios I would be very thankful.

Have attached a bios dump with this post.
