Welcome to the Lenovo Forums.
Can you try to:
1. Make sure you use the original 65W 20V/3.25A or 90W 20V4.5A AC adapter that came with the unit.
2. Plug the AC adapter in another wall outlet in your house (preferrably another side of the house) - if this works, the original wall outlet that you used before when you got the issue may not be properly grounded.
3. Perform a power drain by:a turning the PC OFF. Remove the battery & AC adapter then hold the power button for 30secs. When done, reinsert the AC adapter and battery then boot into the BIOS by pressing F2. When inside the BIOS, press F9 to reset default settings and press F10 to save and exit.
4. Update the Touchpad Driver below:
Windows 8 32bit / 64bit Windows 8 32bit / 64bit
Let me know your findings
