I have a Lenovo Y570 laptop on Ubuntu 14.04. I have my settings to suspend my laptop whenever I close the lid. However my laptop doesn't suspend when I do so. It doesn't even suspend when I click on suspend (in the "Shut down" menu). I tried solution here and it seems that some of my devices are enabled:

I saw what devices were number 6 and 12 and they are a USB and ethernet controller:
07:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57781 Gigabit Ethernet PCIe (rev 10) 09:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04)
I tried to disable them using
sudo acpitool -W number however I can't disaable them even as sudo. What do I do? Its a problem as I am not able to suspend my laptop and its drains the battery.
