Thanks for your prompt response, but the patched dsdt didn't actually work on the wake up problem and my modified one is the same. system will go to sleep without any problem, either with a schedule sleep at a specific time or from the apple menu and choose Sleep or go to sleep by pressing PC's power button. but once it goes to sleep, the only way to bring it back up is to hold down power button to shut down it, and then i have to turn off and on power supply and restart it, if i don't turn the power off/on first and before i restart it, it'll restart into the sleep state again.

Please help with Lion/Snow Leopard Sleep/Wake problem. here's my modified DSDT.aml DSDT_DFIUTX58T3eH8.aml.zip which i made it using several dsdt tools and i'm using it now and everything seems to work fine, but a proper sleep and wake. i think i can enter system sleep from apple menu or by pressing power button but the system is unable to wake up, nothing ever happen at usb keyboard, usb mouse or power button when i try to wake it up by pressing them. here's the send_me file send_me.zip and this's my original/unmodified DSDT.aml DSDT_DFI_UT_X58-T3eH8_Bios429_Unmodified.aml.zip DFI UT X58-T3eH8 BIOS 4/29 Xeon W3520 12 GB 1333MHz DDR3 ATI Radeon HD 5850 Thanks.
