Re: U410 Battery Gauge Rest questions...

That discharge rate of between 8000 with spikes of  12000 is good, so it does not seem to be anything pulling your battery down, i would keep an eye on the discharge rate though.

 

what does battery bar say you battery wear level is?

5%

 

Also, the discharge rate did get way above 12000 when playing Frozen Synapse - but that's quite CPU and GPU intensive game, so that's no surprise at all.

Re: U410 Battery Gauge Reset questions...

A further question:

 

I've started using the "Optimize Battery Health" function of the Lenovo Energy Management software (which only charges the battery to 60%), in order to prolong the total lifespan of the battery.

 

This however, of course, reduces the amount of time between re-charges.

 

So, my question is this:

 

Is it a good idea to connect the laptop to mains power when doing cpu/gpu intensive tasks (for  example watching streamed TV on demand, or playing games), regardless of the battery charge level?

Or will this lead to greater battery wear, because it would lead to more frequent, shorter, charge/discharge cycles?

Hi Scott,

 

for detailed information about proper Battery usage please have a look at 'Battery University' site...

Re: U410 Battery Gauge Reset questions...

Thanks Zehnsteine,

 

I had already looked at the Battery University site - it was that that lead me switching to the Optimized Battery Health setting in the Lenovo Energy Management program.

 

However, it really doesn't help with the question of whether I should have the laptop on mains power when doing CPU/GPU intensive tasks.

 

On the one hand, having it on mains power causes the bettery to charge, which causes wear, but on the other, not having it on mains causes the battery to discharge more quickly, which also causes wear.

 

But, which of the two situations is better?

 

That is the question.

Thanks, but that thread also doesn't answer my question.

Re: U410 Battery Gauge Reset questions...

Well, I still don't know whether it's the right thing to do or not, but I have been running on mains when doing CPU/GPU intensive tasks (e.g. watching video/gaming), and have had BatteryBar running for a while now, and it looks, in terms of Full Runtime, I'm doing the right thing, because (after initially dropping to <5hrs) it's been going back up - currently sitting at 5:24, but I've seen it as high as 5:30 recently. :-)

 

And on 60% charge that gives me about 3hrs runtime.

 

Which is not fantastic, but not hideous either.
