you may have to check bios settings after its flashed and make sure any applicable settings are still set or if not, set them appropriately.
if none of that works, this is a fix that works for ideapad330 that may also work for your laptop.
To download and install, run this in a terminal: git clone https://www.github.com/Jookia/elan_i2c_dkms cd elan_i2c_dkms sudo dkms install . Then reboot your machine.
EDIT: the above git is for IdeaPad330 made by Jookia, and below is a version to work for the IdeaPad 130 modified by @aswathkk
git clone https://www.github.com/aswathkk/elan_i2c_dkms cd elan_i2c_dkms sudo dkms install
