Anyone having problems with BIOS update ver 100 for the DZ77BH-55k?

After updating to this version I have lost the ability to wake the system from sleep state. I always have to use the power button to start the system. I thought that was strange. That is the only issue I am currently having after the update.

Hi, kurt person. I have some questions about your issue:

What operating system are you using?

Did you check if the power options in BIOS changed by any chance? What options are enabled? For example Deep S4/S5 or Wake from S5… You may want to reset those settings to default.

Windows 7 Pro. No changes that I noticed. I will take a detailed look and return to default settings. Another symptom I have been experiencing in the last couple of days is a cycling out of sleep mode by itself for extended periods, hours. At night I end up shutting down to avoid having a bright monitor waking us up. I'll reply with any other items I find or discover. Thank you for the reply.

So, this means that it does not wake up by using the keyboard or mouse, right?

I got an idea about the second issue; you may want to pay attention to the time when the system wakes up by itself or check the Windows* Event Log just right after it happens. You will see a Power-Troubleshooter event (ID: 1) that reads like this:

The system has resumed from sleep.

Sleep Time:

Wake Time:

Wake Source: Device - USB Composite Device (I used keyboard)

This way we may have know what triggers the issue.
