hi kimo_land,

 

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:

 

Synaptics Touchpad Driver       Touchpad Driver (Synaptics, Cypress)

Windows 8 32bit / 64bit            Windows 8 32bit / 64bit

0mtp05w8.exe                         0mtp15ww.exe
90.5MB                                   243MB

 

 

 

Let me know your findings

 

Cheers
