ubuntu 16.04 wakes up immediately from suspend after installing Fprint in lenovo T530

Question

I have read the posts on stackoverflow 1 and 2 but I cannot find which to disable, I'm having Ubuntu 16.04 on lenovo T530 with nVidia graphics. I installed the finger print functionality following the answer posted by Kostanos in here. After installing it the finger print got working fine, but the laptop got started to wakeup immediately from suspend. Here is the output of cat /proc/acpi/wakeup

Device  S-state   Status   Sysfs node
LID   S4    *enabled   platform:PNP0C0D:00
SLPB      S3    *enabled   platform:PNP0C0E:00
IGBE      S4    *enabled   pci:0000:00:19.0
EXP3      S4    *disabled  pci:0000:00:1c.2
XHCI      S3    *enabled   pci:0000:00:14.0
EHC1      S3    *enabled   pci:0000:00:1d.0
EHC2      S3    *enabled   pci:0000:00:1a.0
HDEF      S4    *disabled  pci:0000:00:1b.0

and I run a log to find out which cause the system to wakeup, here is part of what the log indicate

journalctl --follow
