Gave a try on the bootpack.
Touch pad works and recognized as mouse - better than previous
Display seems to have recognized the ambient light sensor because it has the auto-adjust brightness option, however, VGA doesn't work, when I plug in, everything seems to freeze and have to force shut down - I have been using the external display without any issues.
It still doesn't sleep, although it seems to have no issues with power button now but still around the same issue, gives below reason:

Other items like sound works pretty well like before, but the audio device is not recognized as PCI in system info(which I have no problem as long as there's audio output) - it also doesn't play the charger-connected sound during startup but I have no issue with that.
Possibly I'll have to merge the setup to find the best match, I'll appreciate any further suggestions
