Abstract
Systems and methods for determining the state of health for a capacitor module are provided. In some embodiments, a method for monitoring the health of a capacitor module comprising an array of capacitors is provided. The method may include steps for disabling a charger coupled to an array of capacitors of the capacitor module, determining if the capacitor module is healthy based at least on operating values of the capacitor module, and enabling a write back mode for the memory module if the capacitor module is determined to be healthy.
Claims17
An information handling system, comprising:
- a processor;
- a memory module coupled to the processor;
- a capacitor module associated with the memory module, the capacitor module comprising an array of capacitors coupled to a charger;
- and
- a controller coupled to the capacitor module, the controller configured to:
- disable the charger coupled to the array of capacitors;
- after disabling the charger:
- enable a write through mode for the memory module;
- determine if the capacitor module is healthy based at least on monitored operating values of the capacitor module before the capacitor module is fully discharged, the monitored operating values including a time duration for each capacitor in the array of capacitors;
- maintain the write through mode for the memory module if the capacitor module is determined to not be healthy;
- and
- enable a write back mode for the memory module if the capacitor module is determined to be healthy.
