Hi everyone,

 

My laptop is advertised to have a 6 Cell, 83Wa battery. 

 

However when I lookup the battery info using HP Support Assistance, it only shows cell voltage for Cells 1,2,3  (0 for cells 4). The same occurs when I use the UEFI diagnostic utility on boot-up.

 

Strangely when I look at component information for battery in UEFI, the info screen claims it is a  83Wa battery.  Is this a bug in the diagnostic utility or am I misunderstanding something (like is it 83Wa with 3 Cell or 6 Cell or do the number of cells matter )? 

 

I am experiencing battery life way below advertised rates (like 30% of what is claimed) so I am just trying to get to the bottom of this. I can barely get to more then 2H on battery just on MS word and some light browsing with low brightness setting and on "better battery/battery saver" modes.

 

Yes, I am calibrating the battery right now so I hope that improves things.

Good news, it looks like I was able to fix the problem with the battery life.

 

The culprit was an application called Corsair iCue, which is sort of all-in-one control center for Corsair keyboard/mouse/headphones /etc.

 

The problem was that the battery usage would not show up under the Corsair application but instead it would leech power under one of the core windows kernel processes such as  "System" (which made it hard to detect using task manager or app battery usage).

 

By running various report using powercfg.exe and doing some detective work, I was able to discover the start date where my daily battery life dropped from 4H to 2H! Once i figured that out, I looked at programs based on installation date and found the culprit. 

 

Not only my battery life estimation now in the 5-6H range, the laptop is now running much cooler (with low fan noise) and the cpu usage is under 5% when I am doing light work. 

 

So for all those using Corsair accessories and have iCue installed, it might be something you want to look at.
