can't wake inspiron 5675 from sleep
I have backup software that I'd like to run at night. I have computer set to sleep but it won't wake up without pushing the power button. Any ideas of how to get it to wake up? I've even tried task scheduler to wake computer at just a few moments before my backup program is to run. Nothing. Sound a sleep.

Are you expecting the PC to wake up entirely on its own or be awakened by the backup software to run the backup? You may have to play with the Advanced settings in the active Windows Power plan and/or with Sleep States in BIOS setup.
If you're trying to wake it up by moving mouse or pressing key on keyboard and it won't wake up, reboot and immediately press F2 to open BIOS setup. Look for a "USB Wake Support" option (or similar name) and make sure it's Enabled. Be sure to save the change when exiting setup. NOTE: The manual for the I5675 doesn't show BIOS screens so I don't know if a USB Wake option exists in BIOS on this model

I have problem waking up my Inspiron 5675 from sleep and followed your solution above did not fix the problem. It attempts to wake up after moving mouse or press the keyboard "Enter" key but failed. Monitor shows "No signal" then, back into standby mode.
There is no new hardware added, just drivers and BIOS updates. Don't recall having this problem prior to BIOS version 1.3.6 (not totally sure it's the latest BIOS that cause the problem). The following error event may give a clue for solution. I appreciate your assistance in this matter.

How is monitor connected, HDMI, DP or...?
Open Device Manager and expand list under USB. Double-click a root hub and click its Power Management tab. Uncheck the box "Allow PC to turn off...". Repeat for all USB root hubs. Then expand list under Human Interface Devices in Device Manager. Double-click each entry and if it has a Power Management tab, uncheck that same "Allow PC to turn off...". Reboot and see if that solves the problem.
If not, open the Active Windows Power plan and click the link for Advanced options. Disable Hibernation, disable Hybrid Sleep, disable USB Selective Suspend and disable PCI Express Link State Power Management. Save the changes to the Power plan and reboot. Does that help?
