very slow on battery ,very fast on power

[GodLikeBG]

Hello Guys

I reacendly bouth HP EliteBook 840 G3 and i did upgrade the machine havily.

Original config CPU - i5 6200U, RAM - 4GB DDR 4, HDD - 500GB WD Black

Now is with CPU - i5 6200, RAM 16GB DDR4 Corsair, SSD - Samsung Evo 860 500GB

And the problem is that when im on battery its very very very slow ,i did set it up on high performence it was a litle better but still very slow. there is no system resources usage abore 14 ,20 ,25 max % on the ram cpu or disk

When i plug in my power supply sudenly the laptop becomes rocket fast very very vast as it shoud be.

Anyone have any ideas ?

P.S. i have instaled and re instaled all the drivers possible checked intel site for updates and i did them too ,no effect. Set on bios for video dedecated 512 mb ,set in Intel Graphics Properties high performence too ,no efect.

Hi

I suggest you look at the power plans that are existing on your device.

Hi

i already mentioned that the power plan is High performance set from windows mobility centre.

I would first do like Professor suggests and check the power profile.

You can create a new profile in Control Panel->Power options->Create Power plan and max. out the settings to test

There are some utilities you can use to diagnose as well.

From Admin Command prompt the powercfg program lets you generate various reports (among other things)

Type powercfg /? to get help

You can also download the Intel Xtreme Tuning Utility to run some benchmarks and monitor processor performance, throttling, temperature at the same time.

Hi

I did try to set up my own power plan on max no effect same as before

i did diagnose the battery with hp tool for that

i will try powercfg 

and i'm downloading Extreme Tuning Utility

is there a hp power manager or tool or driver ,how come some laptops have on power setings hp power setings recomended

somthing else interesting when im on battery my fan its not working and temperature its not going above 41 C

same max temperature on stress tests for cpu and m

I was beginning to think if there could be some limit set in the power supply as you have a heavily loaded system.

In the XTU you can monitor the core voltage in both the graph and numerical value (the tiny wrench icon).

Also you could monitor the battery voltage with i.e. this tool:

I would be a bit surprised if you noticed much drop in battery voltage with  a new battery during the benchmark. I would think it's more like some limit being set in software somewhere, but who knows.

I think this thread somehow crashed last night..lost some of my messages an now one of your's is in a new threads. Let's see where this ends up to.

I wrote that some of the Lenovo's have had similar and weirder issues that were eventually fixed with a system firmware update.

 As a stopgap some users had used a utility called Throttlestop, which can be used to destroy the CPU and other things if set up wrong but can also be used to extend battery life by throttling back.

Have not tried it myself so this is not a recommendation, just something I found.

Here's a link to a guide:

PS. Note that you need to reset Intel  XTU settings to default and then uninstall it before using Throttlestop if you plan to try.
