Elitebook power management

HP Recommended
elite dragonfly
Microsoft Windows 10 (64-bit)

My EliteBook came with the HP Power Manager installed. When I open this program, it immediately complains that Power Control is not enabled in the BIOS. However, I is not possible to enable this option in the BIOS (Option is there, but I can't enable it).

What is it for?

How can I enable it?

 

I am getting nowhere near the advertised battery life.

The industry has used MobileMark 14 benchmark to determine advertised battery life... Unfortunately, the benchmark makes (IMHO) non-real life settings to achieve the published numbers... A newer version of the benchmark, MM 18, will be more realistic and HP will be publishing MM18 going forward on new models...

To answer your question, i would first make sure your system has up to date BIOS and drivers, and recommend the use of HP Image Assistant for that... also recommend the install of HP System Default Settings softpaq, which adds an HP optimized power profile... last, the main culprit of battery use is often the display, and lower the display brightness as long as it is comfortable for you will greatly benefit battery life

You do not mention if you have a FHD or 4K display with your Dragonfly, but a 4k lcd will take, probably, a 3rd of battery life compared to a FHD display

I work for HP. However, all opinions and comments are my own.

Hi Soccer_Dan. Thanks for the reply.

I do not have a 4K display. I do have a 4 cell battery and higher rated power supply. So was expecting solid battery performance.  I use a LAN connection, spend most of the day in Outlook, and about 4 hours on Teams calls. The machine is 3 days old and I'm getting no more than 4 hours out of the battery. I have the HP optimized profile set but this only seems to offer settings around shut down and sleep. The machine has the latest bios - was updated by when I got the machine.

 

I'm struggling to see much improvement with this all new high-end hp dragonfly 2 in 1 vs my 5 year old Asus zenbook 😞

 

Appreciate any inputs

Hello 

 

HP Power Manager software has nothing to do with how long the battery last.

DRagonfly may be built with two different battery size: 

2 cells , 38 Whr

4 cells, 56,2 WHr

 

so first of all check which battery you have inside your dragonfly.  Obviously 38 Whr battery last less than 56,2 WHr.

Even more you should check your display. is it a 4K display or a full HD disply ? 4K display consumes a lot of current and battery charge drop quickly.

bye
