Sony :: Solution For All Vaio Battery Drain
Jul 26, 2009
I was running an FW and noticing huge percentage drop when I would hibernate and leave it unplugged overnight, sometimes it would be about 30%. However the percentage would always remain 30% lower then when I powered it down for a while so I figured my battery life was not affected overall and that the battery indicator was wrong. Well it turns out that I was wrong, I can usually squeeze out 2 min per percentage if I leave my computer idle and allow the screen saver to popup while on battery. However after the 30% drain overnight I noticed my overall battery life was affected severely, with 1 overnight on hibernate session my battery life went from on average 2 min per percentage to 1.33 min per percentage.
Possible Solution:
Turn on battery care function on the Vaio Control Center and set the custom setting at 100%. Having done this my battery during hibernate (and shutdown) overnight drops only 1-2%.

I just got a CW i5 from Best Buy.com a few days ago (its the VPCCW27FX). I have since noticed that it has serious battery drain issues.
My computer seems to lose about 7% of battery life PER HOUR when in sleep mode (although at some point it seems to put itself into hibernation). (I just put it to sleep for 2 hrs, and it dropped from 90% to 77%. Last night put it to sleep at 40%, and computer would not start up this AM w/o immediately going into hibernation again b/c battery totally drained)
Dunno why this is happening - computer seems to be asleep (screen off, blinking orange LED on front, etc.) and certainly is hibernated when I start it up again (vaio splash screen, etc.), but if I am losing 7% an hour, I will need to return it.
Battery life seems to be okay when I am using it though - watched and hour of DVD last night on battery, which dropped the charge from about 80% to 40%.

What is Battery Drain?
-When your computer is turned off or in sleep mode and looses large amounts of battery life.
How do I know if I am affected?
-To my knowledge, ALL Vaio CW computers (at least with the i5 and 330m combo). I have come to to this conclusion because I have had two of these with the same issue and I have yet to see more than one person say they do not have it on a Vaio CW
How can I fix this?
-Right now there is no fix for loosing battery life while 'Shutdown'. As for sleep mode, you can help make the loss less substantial by doing a 'clean install'
Instructions here
And also make sure that you have these settings in the 'advanced power options'
Tests:
All tests have been run on two different VPCCW27FX notebooks
Test 1: 100% Battery, 4 hrs shutdown: 90%
Test 2: 65% Battery, no HDD, 3hrs shutdown: 48%
Test 3: 48% Battery, 'Power Saver' battery mode, 5.5 hrs shutdown: 20%
Test 4: Wifi Switch off
Test 5: 50% Battery, Battery out: 50%
Conclusions:
At the time being, there is no fix or known cause for the battery drain while shutdown. For now, myths of a clean install or using different windows battery settings make no difference, which means this is either a problem with the motherboard, BIOS or the battery it's self.

Several times I charge the laptop to full and turn it off. When I turn it back on moments later, it shows the battery at 75-80% and it always does this.
I call up customer service (only to find out that they are a bunch of retards because they always refer to their "manual") and they say that this is normal. Which I think is total bs, because they specifically state 3-4 hours of battery life

I am starting this thread in hopes of getting to the root cause of the battery drain found in the VAIO Z-series (among other lines I've been told).
Battery drain here is defined as the amount of battery the laptop loses when turned completely off and left to sit for a period of time. If the battery is removed, the loss is insignificant: 1-2% in a week's time. If the battery is left in, the loss is significant: 5-10% in a 24 hour period.
I am here to try and determine what causes this loss. What I would like those who wish to participate to do is the following:
1. Charge your laptop to 100% (battery care must be disabled to do so).
2. WHILE THE LAPTOP IS PLUGGED IN, shut the laptop down completely (no sleep/hibernate/low power state, in other words, OFF)
3. Let the laptop sit unused for at least 24 hours
4. Just prior to starting back up, PLUG THE LAPTOP BACK IN, start it up and record your battery %
5. Post your battery loss here as well as your laptop's configuration
Keeping the laptop plugged in on shut down and start up removes the possibility of a large amount of juice being used for either process which has been documented to happen..

Us VAIO users will most likely have (and still do) experienced the common and annoying battery drain issue, which Sony has dubbed a 'feature'.
Sure, Lithium ion batteries do suffer some degrading when charged near 100% or fully discharged at 0%, but many here will have experienced the battery draining from 80% (Battery Care on) to 30% (a few days later), which, to everyone here, is NOT beneficial to the battery in any way............

I've had a strange people recently plaguing my D630 (purchased June 2008).
The battery states 100%, pull the plug, and within a minute, it goes to about 10%, then the laptop shuts down.
Now, here's the catch - the battery is still good. I've tried the battery out in my other D630 and it works perfect, still holding a charge. I also tried the other laptop's battery in the problem laptop and it did the same thing.

I've got a relatively new XPS 13. I noticed that I seem to lose battery charge even when I'm completely powered off -- about 10-15% overnight. Is this common or is something draining the battery that shouldn't?

I last used my DM3 about 2 1/2 weeks ago. When I shut it down the battery was at 100%. When I powered it up today, I had only 58% battery charge. This drain seemed excessive to me so I called HP and they seem to have agreed with me as they are sending me a new battery for free under warranty.
Anyone else notice excessive battery drain when the unit is shut down?

I have an Acer 4810TZ timeline (SU4100 processor). I had charged the battery up to 100% and then left on an 11 day vacation. When I came back, I found the battery to have only a 16.7% charge left on it. Is this an excessive lost of battery over an 11 day period? My laptop was left shut down (it was not in sleep or hibernate mode). I would think the drain on the battery would be minimal.
Is my battery defective or is this normal? I've had the laptop for about 2 months.

here we go, acer 3810tz :
1.Laptop turned off -> charger unplugged -> turned on after 15h, battery bar:
99,99-93,0= 6,99% of drain
2.Laptop turned off -> charger stays plugged -> turned on after 15h, battery bar:
99,7-99,0= 0,7% of drain
3.Charger unplugged (laptop goes to on battery mode) -> laptop turned off ->
-> turned on after 48h, battery bar:
98,0-97,0= 1,0% of drain
Conclusion:
There seems to be a bug in BIOS power managment, so:
1. Unplug charger, laptop goes to on battery mode (green leaf).
2. Turn off laptop

i just bought a Thinkpad e535.Every time I turn off the laptop (not hibernating, not sleeping) and unplug the power cable from the Ac Outlet the battery loses around 20% of charge every 24 hours,
What I've already done to troubleshoot:
-Disabled USB always on in BIOS
-Disabled Wake On Lan from Windows AND BIOS
-Running command powercfg /devicequery wake_armed to see if any device is programmed to power on the laptop
BIOS version is the latest one (2.08)
Power Manager software is 6.32

Fresh load of Windows 7 x64 7229 and when I put my machine into standby the battery seems to drain incredibly fast....almost like it is on. I will standby the machine before I go to bed and in the morning it's dead with 0% battery.
I used to do the same thing with my D630 and in the morning I would have 85% or so on the equivilant 6 cell battery. Is there something I am missing.

Earlier today, my Yoga 3 Pro decided to stop charging. When plugged in, the battery continues to drain as if it was not plugged in. I have tested the A/C adapter by plugging in my phone with a micro USB and that worked fine, and the USB charging slot works when my wireless mouse is plugged into it, so I assume it must be the strange Y3P USB cable that is not working.
Would a normal USB to USB cable work for charging my laptop? If not, how do I replace that "kink" USB cable?

On my T540p, I configured the rapid start technology according to [URL] ....
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days. I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to [URL] ....
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided?

I've seen many posts from people who want to use a traditional 2.5" HDD in their new Z11 laptops instead of the DVD/BR drive. I have a working solution.
I picked up a Lenovo Ultrabay III adapter for a W510 I had on order and subsequently canceled after 2 months of delays in shipping.
The DVD drive is attached via a micro-SATA connector. If you haven't seen one before, here's a comparison to a regular SATA connector .....

So I bought a Sony Vaio FW-340DW for school which is the lower end with the X-Brite Eco screen. However, I have noticed something about the battery.
When I'm on the Vaio Optimized battery plan, I get 2.5 hours of battery life. But, When I switch the battery plan to Maximum Battery I still get 2.5 hours

I have a Vaio CR-190 and am having battery problems. Over the past couple months, my battery would show a full charge when plugged in, but when I would unplug the computer the battery would literally drop from 100% to 80% and began dropping futher. A few weeks ago, the battery would drop from 100% to 50% or so when unplugged and the battery would quickly drain. Recently, however the battery holds no charge at all and the computer will only run through the a/c. My battery management utility shows an X through the battery and says there is no battery detected even though the battery is properly installed. Everything else on the computer is running fine. I'm just looking for some advice on what's the best steps to take next. I've read that Sony has had some problems with batteries suddenly dieing and wondering if that's what it sounds like. The battery is from Sony and is the extended life larger one if that matters.

Being a long term TX user, I eventually made the switch to the TZ, didn't need blue ray and didn't much care for the chrome sidings on the TT.
It's a lovely little laptop, but I have noticed a few things - mainly the battery is nowhere near Sony's claim of 7 hours.
My TX would give me a good useable 4.5-5 hours, this one barely struggles past 3 hours, even with the power management on battery life, screen useably dimmed and the CD/DVD off

First time poster, long time viewer.
I was just wondering if anyone experienced a battery increase after down-grading their Vaio Z from Vista/Win7 to XP? If so, by how much?
I'm currently holding a Z710dd (canadian vaio) with a standard battery with windows 7 installed. I previously had a netbook that lost a good hour and half from Windows XP to Windows 7. Even after disabling a lot of the windows aero mumbo-jumbo and themes

For example now I have open my laptop at 89 % and after 20 min goes down at 71 %. I have WIN 7 installed over 2 months but this problem appear about 4-5 days ago, so I think isnt from my OS or it may it be?
