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.

Acer :: Findigs About Timeline Excessive Battery Drain

Mar 6, 2010

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

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?

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

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

HP ProBook 4540s OS/Software :: Battery Drains When Laptop Turned Off - Unknown Device

Aug 21, 2014

I just purchased a new probook 4540s core i5 with win7 x64 system.
 
Firstly, When battery full charged then turned laptop off for a few hours or next day it becomes 99% or 98% although its plugged in Ac power. Shutdown again for 1 hour and turn on it turns to 97%. Is that ok or there is problem in battery specially it shows that ( Plugged in, Not chareged ) so laptop should operate at AC adapter and battery remain 100%. Secondly, I have an unknown device can't find it as shown in figure below.

HP/Compaq :: Dv5t Excessive Battery Wear

Jan 16, 2010

Does anybody else with a dv5t have excessive battery wear? I purchased the laptop in August of 2008. According to hwmonitor my battery can only hold 30758 mwh down from the designed capacity of 47520 mwh. I rarely used the battery. Maybe once a week for 5 minutes to move the laptop.

I asked a friend with a dv5t purchased around the same time and his capacity is down to nearly 27000 mwh. Our laptops are the same except his has the intel integrated graphics while i got the 9600m gt. Also he uses the battery almost daily.

When i first got the laptop i got nearly 2 hours out of it. Now i can barely get an hour.

We both calibrated our batteries a few times by fully discharging and fully charging a few times which did nothing.

I know that batteries experience wear but does this seem excessive? I believe the estimate is about 10% a year. But this is almost 50% wear in a year and a half.

Acer :: 8930g (from 2008) Laptop Suddenly Turned Off And Now Won't Boot

Oct 12, 2009

Acer here. It's an older 8920g, but it has a 18.4inch screen and an Nvidia 9500 GS card

Basically here's how it goes:

Laptop unplugged, full battery or near full, placed on a bed (you can see where this is going), playing emulator games

Later, it suddenly turns off.

Upon trying to turn it back straight away, the laptop turns on, but only a blank screen is present.

I recommended to leave laptop off for 2 odd hours. Tried again after 2 hours, same result.

I got hold of the laptop now, basically it turns on, then suddenly flicks off and then back on again, and does.... nothing. The audio/media pad responds though (i.e. hold and mute button is responsive). I tried to take out the battery and turn it on, nothing.

Then I put the battery back in and turn it on, same result. Screen remains black throughout all scenarios.

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.

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%.

Dell XPS 13 :: Battery Drain While Powered Off?

Apr 18, 2013

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?

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 :: 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 :: 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..

Lenovo Y510P P/Y/Z Series :: Battery LED Turned White Which Indicates Battery Is Fully Charged

May 31, 2013

My 2 day old Lenovo Y510P laptop has a problem with charging. I noticed the battery was never going above 60% charged. I left it plugged in for over 24 hours and nothing changed. So I decided to completely drain the battery and used the laptop until it died. With the laptop off I left it plugged in until the battery LED turned white which indicates the battery is fully charged. Unfortunately the battery still shows 60% charged.

Dell :: E6400 + 6 Cell + Windows 7 X64 7229 + Standby = Serious Battery Drain?

Jun 19, 2009

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?

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?

Dell Inspiron 15 7537 :: Laptop Freezes When Turned On Or Resume From Sleep

Mar 15, 2014

I received a new Inspiron 15 7000 yesterday, and am experiencing the following issue:

Approximately every other time I try to either a) Turn On the laptop or b) Resume from sleep - the laptop freezes.

This is often accompanied by the backlit keyboard being lit and staying on. Nothing else happens. No screen etc. or other response. The only way to get the laptop to work is to hold down the power button to kill the machine, and try again. This usually works and the system starts in a seconds.

Acer :: New Laptop -- Battery/AC Adapter

Aug 28, 2009

My concern with this is the fact that with the battery removed, there's going to be a big space underneath the laptop where the battery used to be that's just asking for a bunch of dust and dirt to come in. Is that an issue? Or am I mistaken in believing that removing the battery sounds like a bad idea?

Also, is it necessary to remove the battery if I intend on using the AC adapter most of the time, since the only time I'd be away from a wall jack would be when I travel. When I'm at home, I can easily just plug it into the wall rather than use up the battery.
