seanmcken, install kernel-power-settings. IIRC, your device gets automatically undervolted after installing KP by SmartReflex, but I may be mistaken... Anyway, open x-term (CTRL+X) and type sudo kernel-config show , and copy-paste output here.

Also, SmartReflex may be total failure (for my device it is, at least), and you can try undervolting manually, using available profiles or creating your own. sudo kernel-config load lv for a bit lower voltages.

Finally, what about your battery? Is it new or old, what brand it is, did it behave different prior to installing KP?
