adaptive vs. battery

I don't know if it is just me but...

I feel as if the adaptive mode on vaio power settings makes my computer run slower than battery...

any ideas?

 

it seems as if no one has the same problem...

but it is a fact..

my computer runs faster when I set the cpu option of the vaio power management to battery, considered to adaptive...

when I choose adaptive, the cpu just lags constantly

 

I'm guessing with adaptive, the cpu will change on the need basis, whereas with the battery, the cpu will be at a high/performance setting when the battery is still full, then it will change to lower speed as the battery life diminish.
I could be wrong though

 

What model is your laptop? In S and TX, you can configure "Adaptive" and "Battery" mode's CPU setting and you can have a faster battery mode than adaptive mode. Also, adaptive means the CPU has to calculate how fast it can run as well, so there is a chance of "miscalculation" and power management still prohibits high CPU speed even though the system needs it. My personal solution is either quit the program then re-enter or force the power management to max. performance before loading certain programs.

 

Have you checked at what speed the CPU clocks with Notebook Hardware Control? In Max Battery mode mine won't allow the CPU to clock higher than 800Mhz and in adaptive mode it runs up to 2Ghz sometimes.

 

Could someone post some custom dynamic switching values as a sample?
I found these figures reading NHC guide, I guess they’re Intel’s voltage samples:

Multiplier:
6x
8x
9x
10x
11x
12x
14x
15x

Voltage #1
0.988V
1.052V
1.084V
1.116V
1.132V
1.164V
1.228V
1.260V

Voltage #2
0.988V
1.068V
1.116V
1.148V
1.196V
1.228V
1.308V
1.356V

I’m looking for a configuration to maximize battery life without compromising the stability of the system.

 

I've only changed the voltages on a few multipliers, but these settings run stable for me:

6x - 0,732V (anything lower is unstable on my system)
8x - 0,828V (can still be optimized)
9x - 0,876V
15x - 1,308V

 

Thanks, I'll give it a shot!

 

Boomfunk, are you sure about the last value (do you have a 2.0Ghz Pentium M 760?)? 15X 1.308V isn’t a bit too high, the highest figure I have is 1.244V.
I’m very inexperienced about undervolting, so I’m going to test your patience asking for an extra help!

1. Once I set the custom values you gave me I need to tick “Enable custom dynamic switching” under CPU speed, right?
2. If I want the system to run the CPU without being undervolted I just need to disable “Enable custom dynamic switching” and that’s it?
3. Will the new values be effective when AC is offline only or will they work when plugged in too?

Thanks a ton!

 

bump, anybody?

 

Sorry for my late reply, concerning your questions:

1.) You don't need to enable custom dynamic switching if you don't want to. The CPU will run with the Voltages you have specified in any case.

2.) No, you need to remove the tick below "on" in the CPU Voltage Control tab.

3.) They will be effectiv ein both cases

I have a Pentium M 760, hmm I can go up to 1.356V. Didn't really want to undervolt at 2ghz because when running at this speed I'll mostly be connected to the mains, so no need to save energy

 

It's all right! Thanks for your help.
