The tool supports **undervolting** the CPU by configuring voltage offsets for CPU, cache, GPU, System Agent and Analog I/O planes. The tool will re-apply undervolt on resume from standby and hibernate by listening to DBus signals. You can now either use the `UNDERVOLT` key in config to set global values or the `UNDERVOLT.AC` and `UNDERVOLT.BATTERY` keys to selectively set undervolt values for the two power profiles.
### IccMax (EXPERTS ONLY)
The tool now supports overriding the **IccMax** by configuring the maximum allowed current for CPU, cache and GPU planes. The tool will re-apply IccMax on resume from standby and hibernate. You can now either use the `ICCMAX` key in config to set global values or the `ICCMAX.AC` and `ICCMAX.BATTERY` keys to selectively set current values for the two power profiles. **NOTE:** the values specified in the config file are the actual current limit of your system, so those are not a offset from the default values as for the undervolt. As such, you should first find your system default values with the `--monitor` command.

### HWP override (EXPERIMENTAL)
I have found that under load my CPU was not always hitting max turbo frequency, in particular when using one/two cores only. For instance, when running [prime95](https://www.mersenne.org/download/) (1 core, test #1) my CPU is limited to about 3500 MHz over the theoretical 4000 MHz maximum. The reason is the value for the HWP energy performance [hints](http://manpages.ubuntu.com/manpages/artful/man8/x86_energy_perf_policy.8.html). By default TLP sets this value to `balance_performance` on AC in order to reduce the power consumption/heat in idle. By setting this value to `performance` I was able to reach 3900 MHz in the prime95 single core test, achieving a +400 MHz boost. Since this value forces the CPU to full speed even during idle, a new experimental feature allows to automatically set HWP to performance under load and revert it to balanced when idle. This feature can be enabled (in AC mode *only*) by setting to `True` the `HWP_Mode` parameter in the lenovo_fix config file : https://github.com/erpalma/throttled/blob/master/etc/lenovo_fix.conf#L41 .
