Wow.. I have never heard of DSDT and, I have no clue how to apply this patch! My screen will not turn back on after closing the lid. I purchased a new motherboard for my Dell E1505, since the sound stopped working on the other. Well this new one works great, except for when I close the lid. I have also googled and read forums on DSDT and it’s foreign to me! Anyway able to help me apply this? Thanks in advance. Email: cortlands @ Gmail.com

I am another Ryan N. with a D620 that has the same problem. I did not try the patch or looking at the DSDT problem. Also, my laptop only occasionally exhibits the problem (seems like most frequently when I close the display and say “oh, wait” and open it back up — after that, the display seems to never power up). Any ideas?

I have a D620 with a similar problem, unfortunately your patch does not match my DSDT.

Would you mind having a look at mine and seeing if there is anything you can do do help?

acpid may be useful to you for other purposes. It doesn’t read the DSDT table, it just responds to ACPI events from the kernel (and the kernel is the thing which reads and interprets the DSDT). For me, the only reason I had it acpid was to turn my damn screen back on when opening the lid. Now that I have fixed that on another level, bye bye acpid :)

so, this actually means, that if you have a complete and error-free dsdt table for your machine, acpid is not needed? only if you want to achieve special behaviour? I always thought the acpid just reads the dsdt table… -_-

Thanks for this patch! I just applied it to my DSDT on my Dell Inspiron E1505 / Inspiron 6000, and it works great. I’ve been fighting with the screen staying off for what seems like forever, and now it “just works.”

This will sure make life a lot easier when I try to get suspend working again. Most of the problems I’ve had have been related to the screen not turning back on.
