Help this exact thing just happened to my E1505 last night and I have no screen, the computer is on but no display. I know this because we took the cover off and if you press the stanby switch you can see the screen for a few seconds then it goes back off again. What is a DSDT and how do I do this? If you cannot log onto computer and cannot see how can this be done? Please help me as I cannot afford another computer, I live on social security.

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… -_-
