Battery drain problem on new Vaio SR?

Hello,
Is there anybody solved battery draining problem?
Is this problem on all Vaio series? ex Z, FW, SR, SZ
Is it fixed in new Vaio SR or Z series?

 

i'm also facing same problem on my sr29 it drains about %5 in 12 hours i dont know what to do about this problem. Also my battery is not so tied a little bit loose. Is there anyone also have this problem?

 

There is no solving it; it seems to be a hardware issue.

All the vaio models seem to be plagued, including the latest revisions.

 

from what people have been reporting, it seems that the battery drain issue was done on purpose.. by sony

perhaps it's a gps locator thing, tracking our every movement...

 

There was one strange detail on the SZ - shut it down on battery and the battery drain didn't occur as pronounced when restarted immediately...

I don't know if anyone tested this for the SR...

 

The thing that bothers me is the fact that even if you leave the plug in, it'll stop keeping the charge at 100% and it will drain anyway. Is this not the case?

 

If you leave the plug in (with the socket switched on in the UK) the battery will remain a 100%

 

I got my SR 390 on Tuesday and I haven't experienced the battery drain issue. They might have fixed it.

 

It's not something you "fix" as they don't claim it's a "problem." How long did you test it and how?

 

Not ALL models are experiencing this. The FZ-190 I have does not loose ANY power when hibernated or turned off. I thought I was loosing power when hibernated but realized after upgrading from 2 to 3 GB, I was not allowing enough time for the hibernate to disk to finish before removing the A/C. Once I allowed the extra time, my battery loss went to 0%.

Note Hibernate is the S4 state and power off is the S5 state. And if you dig into the device manager you will find that certain devices have in their "Power Data" settings on the "Details" tab a D2 state while in hibernation and a D3 state when powered off. (See attachment)

Here is an article with details about S4 and S5 States: http://msdn.microsoft.com/en-us/library/ms798270.aspx

And one with info about the S4 and S5 states along with the D2 and D3 differences: Power "S" states and "D" states (See pages 5 and 6)

Very important informations thank you. So what must we do shortly?

Could you write this post in Z drainning problem topic too pls:

Fz doesn't has a Battery care Function and the drain happen for all new models with the battery care function !!

 

Yes the FZ does not have battery care function. That brings up three questions:

1. Are you SURE this phenomena is exhibited on ALL models with Battery Care function?
2. Do ALL models that are experiencing power loss have the Battery Care function?
3. Why/how would this software component affect power drain when the machine is powered off???

I am not suggesting you are wrong in linking Battery Care to the issue, just driving the discussion forward. I think you might be on to something, because I tried installing the Battery Care software on my FZ. It installed BUT all of the options were grayed out. I assumed that it was just a piece of software that would monitor battery level and shut off the charge circuit at a predetermined percentage. But since the options were all grayed out, maybe that was because the FZ lacks some bit of hardware needed to implement the functionality. It might be that this hardware component is ALSO responsible for the power loss issue.

Gary

 

thanks ......

 

The Battery care function does work at a hardware level too.

i.e. set it to 80%, switch laptop off and charge - it'll only charge to 80% - no Windows or OS in general involved...

But:
There is more to it than just the battery care function.

Has anybody tested battery drain if he/she shut down on battery rather than AC?

Just to repeat what I said earlier - shut down on battery and start my SZ, loss is 0-1% - shut down on AC and start, loss was 5% - I don't know if there still is a loss...

 

I just got a refurb SR290 off the Sony website yesterday. Ugh, this thing seemed perfect until I got up this morning and turned on my computer to a 93% battery. There has got to be a fix for this, but at this point it looks unlikely.

 

Try shutting down on battery - see how much it drains overnight under that condition.

 

Have they came out with a bios update for this yet? I've only seen a possible update on the 190's but not the 290's.

 

the update for 190's is just a sh.. , it doesn't solve this issue

 

jgill886 - Can you please tell us what and how much time you tested ?

I'm also interested on buying the SR 390 as many other ppl do...

 

my z doesn't seem to be draining either. i used the battery care function to leave it at 80%, no loss on ac. i'm gonna test it on battery soon.

 

Shut down on battery. I used the battery care function after 12 hours. Turned it up and I lost 8% (i charged full 80%).
There must be something wrong with the battery. I just bought this laptop 3 days ago. That's weird

 

Is this problem still exists in new SR490 series?

 

Yes. Sadly. I just bought one, but I think i may have found out what the issue is.

wow, this battery drainage is really bad..... seems like this problem is not new, when is sony going to fix this?

 

I have been trying to follow this and the Z Battery Drain thread to hopefully find a solution. So far nothing has worked. Last night and this morning, I noted the following:

1. Yesterday upon leaving work I put my laptop in sleep mode. Laptop is in my bag for 7-8 hours not plugged in. Later that evening I plug it in and wake from sleep mode. Battery charge indicator does not turn on and software reports @ 80% - fully charged which is correct for the battery care setting I am using.

2. This morning before leaving home I put laptop into sleep mode. Laptop is in my bag for ~45 minutes not plugged in. Upon arrival at work I wake laptop from sleep mode but DO NOT plug in the AC adaptor right away. Software reports 74.3% after only 45 minutes of sleep. I plug in the AC and the battery charge indicator turns on but software shows another ~2% drain before it stops showing a - discharge.

I should note that I am using Battery Bar 3.2 build 63 in conjunction with the Vista battery indicator to see the charge/discharge info and the percentages agree with one another. Based on 1 & 2 above, this indicates to me that this is a reporting problem and not so much a drain issue at least in my case.

So, case 1 is no battery drain after 7 -8 hours. Case 2 is 5.7% after only 45 minutes. I am thinking this points to a BIOS issue reporting the wrong info to the OS. I don't believe it takes almost 6% to resume from sleep.

 

From SLEEP mode? Impossible. Sleep mode keeps the RAM powered up so there will be SOME power drain. It sounds like you are confusing the sleep mode with the "shut down" mode aka power off.

Gary

 

I know the difference and I am not confused. It was sleep mode. Not hibernate and not power off. The yellow light on the power switch was pulsing and when it wakes up, turns green. After that it is almost an instant to the user login screen and subsequent usable desktop.

 

It seems hard to believe that after 7-8 hours there was zero power drain when in sleep mode, since the ram would be consuming SOME power. I guess maybe the power display is just not granular enough to show how much was consumed.

Gary

 

I agree. Sometimes battery says 20 mins left and its same for like 20 mins.

 

I guess that was my whole point. Trying to test for what is going on here seems to be random and different user's seem to have different results. What amazed me was when I plugged in my AC adaptor after 7-8 hours but BEFORE waking from sleep mode, the battery charge LED did not come on nor, did it come on after waking from sleep.

 

OK. So I tried the same thing. Put laptop to sleep. Unplug the AC adaptor and then let it sit for 5 hours. Plug the AC adaptor back in. Wake from sleep mode and the battery monitor indicates full charge (80%) and the battery charging LED is not on. Looks like this is repeatable.

I will try this test for a longer period of time when I get the chance.

 

Maybe the power controlled is defective on many SR's?

 

Something is definitely not right I do think it might be hardware-related with either the battery not being a perfect fit or the AC adapter but can only speculate at this point. Just used up my AMEX pts to get the extended battery which is kinda annoying as it seems like even that will only get me ~ 4 hrs. Turned off DVD drive AND changed the closing of Lid to do "nothing" (per similar thread)...battery still reads 98% charge with 2.5 hrs remaining. It doesnt matter what Power Mode I select either !

Here's an interesting tid-bit : I noticed in Win 7 if I unplug the lappy and after awhile plug it back in, it still shows the battery icon (w/ partial discharge icon) vs the charging Icon....any idea why? And only once in awhile it does this

 

Simple you must switch your hardware wireless button to off. This solved problem for me.
