Sony :: Battery Drain On My Vaio F Series Laptop

Apr 10, 2010

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

Sony :: Vaio CW Battery Drain

Jan 30, 2010

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%.

Sony :: Vaio CW Battery Drain Information

Mar 7, 2010

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.

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%.

Sony :: Vaio Z Battery Drain Diagnostics Thread

May 14, 2009

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..

Acer :: Is This Excessive Battery Drain (while The Laptop Is TURNED OFF)

Jan 1, 2010

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.

Lenovo 11e E/Edge :: E535 High Battery Drain When Laptop Is Off

Apr 8, 2013

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

Sony :: Battery Drain Fix Request Thread

Oct 8, 2009

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............

Sony :: How To: Disassemble Vaio CS-Series Laptop

May 20, 2009

how to open/disassemble my VGN-CS110E laptop but no one had the manuals, etc to how to open it. I have read from several places that the Vaio is like a jigsaw puzzle, and in which case it is. There are always different was of opening different Vaio's. From the "popup" keyboard, to "popup speaker" just to get into the fan. The CS-series is different, you open it as if it were a desktop computer.

First, turn the laptop over so the screen is shut and is on the bottom.

Remove the battery, once removed, there are 2 screws (ignore the 3 black screws), remove the 2 screws.

After this is done, unscrew the screws that is in the casing of the RAM as well as HD. The HD has two screws to be unscrewed, one is hidden thus you have to remove the HD to unscrew it.

In order to disassemble the CS-series, you must unplug a cord that's within the RAM compartment, in doing all of this, slowly lift the underneath piece of the laptop, it should pry away slowly and then you can see the motherboard, fan, etc. You can disassemble the monitor screen from the laptop now as well.

Sony :: Vaio Z Series Manufacturer's Battery Life Claims Mystery

Jul 23, 2009

I've had eye on Z Series for couple days, but there exists a mystery I couldn't figure it out.

I've searched this forum and the net, still no answers.

On the sony's official USA website (www.sony.com)

Sony claims VGN-Z790 CTO has upto 7.5 hours of standard battery life.

However, other preconfigured Z Series laptop such as VGN-Z790DND, VGN-Z798Y/X, VGN-790DLX, VGN-790DKX, VGN-Z790DMR, and/or VGN-720D/B has upto 6 hours of standard battery life. It's mystery I was unable to figure out.

what's difference between Z790 and Z720? (I mean fundamental differences like circuitry design or expansion limitations such as maximum ram support and so. Couldn't figure this out... probably one of those model number decryption wizard would know it.)

Dell :: Battery Drain + Power Off

Oct 29, 2009

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.

HP/Compaq :: DM3 Excessive Battery Drain When Shut Down

Dec 11, 2009

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?

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.

Lenovo Yoga 3 Pro Flex :: Not Charging - When Plugged In Battery Continues To Drain

Jan 25, 2015

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?

Sony :: Is Your Vaio Z Series Laptop Your Main Computer Or Secondary Computer

Apr 22, 2009

Do Vaio Z Series laptop owners use their laptop as their main primary computer or a secondary computer? Do Vaio Z series owners also have a desktop pc as their primary computer and use their Vaio Z Series as a secondary computer? Or is your Vaio Z Series laptop your one and only computer that you always use? Is it comfortable using the 13 inch screen for long periods of time?

Reason i ask is some people have more then one computer and some people just have one.

I'm just wondering if the Vaio Z Series laptop is a good choice as a main computer since it's got good specs and it's nicely portable but will the 13 inch screen be ok to use for long periods even at the higher 1600 x 900 resolution?

Lenovo T400 / T500 :: T540p Battery Drain In S4 Sleep State After BIOS And Intel WiFi Driver Update

Aug 17, 2014

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?

Sony :: (Old) VAIO Z BD Drive Fit In (New) VAIO Z Series

Mar 27, 2010

I'm wondering if the Blu-ray optical drive (Panasonic UJ-232A) of the (old) VAIO Z series will be able to fit into the (new) VAIO Z series? I would really appreciate it if anyone is able to answer my question.

The reason I'm asking is because I'm seriously thinking of selling my VAIO Z690 & just buying the base Sony VAIO Z (VPCZ112GX/S). I may just be able to afford that base model & the icing on the cake will definitely be the UJ-232A drive being able to fit into the (new) VAIO Z series & work.

Sony :: Vaio CR Battery

Sep 6, 2009

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.
