Using the Ubuntu Kernel Update Utility, I've tried Kubuntu 18.04 with the 4.17.14 kernel and suspend and hibernate both work fine on HP Pavilion with Intel Pentium N3540.
(UKUU details here: https://www.omgubuntu.co.uk/2017/02/ukuu-easy-way-to-install-mainline-kernel-ubuntu - 4.18 kernel is also available but haven't tried that yet)
