Precision 7540 - After BIOS update, computer stays stuck after sleep
Hello everyone.
I have a Precision 7540. Every time I update the BIOS via DELL COMMAND UPDATE, the sleep mode becomes faulty: if I close the lid or press the power button while the computer is on, it goes into sleep; however, when I reopen the lid or press the power button, the computer "wakes up" but the screen remains black and the PC does not respond to commands/input, forcing me to forcefully shut it down.
This happens with all BIOS updates after version 1.30, I have installed them all up to version 1.36 and they all have this problem. Every time I perform a downgrade back to version 1.30 and at this point the sleep mode starts working correctly again (meaning that the computer wakes up regularly after going into sleep mode).
Thanks for your help.
