Hi,
I am using the Acer Predator Helios 300 purchased it from Flipkart. It has serious heating issues (CPU reaching 99 degrees Celsius when gaming), and so I have decided to undervolt it using Intel XTU. After undervolting the CPU temperatures have reduced to 85-87 C. However, when I shut down the laptop and opened it the next day, I found that the offset voltage default has changed to -0.133V, the value which I used for undervolting. 
It has changed from default 0.000V to -0.133V and Intel XTU was not running. After startup immediately I found this change by using HW Monitor.
How will I revert it back to 0.000V? Has this been changed from BIOS? I cannot find any voltage options in BIOS.
Please help.
Many thanks!

    Why can't you re-set it back to 0.000v with XTU? Jack E/NJ

    Use the slider you used earlier to set to 133 to set back to 0. And save. This would be now set to defaults.

    You can always use the slider to move it back to 0, be sure to double check on a regular basis as sometimes, it will stay at your undervolt settings and other times it will revert back to 0. So I'd recommend setting up a profile of what you want your undervolt to be so you dont have to keep manually setting it.
