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

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.

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?

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.

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 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%.

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?

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.

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%.

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

For the past 5 months that ive owned m laptop, i have been running the Windows 7 RC.
However, given that i will be leaving the country for the next four months (during which time my RC license will expire) i did a clean install to an RTM (retail) copy of windows 7 ultimate 64 a few days ago. Since then, ive noticed some bothersome issues:
battery life is fluctuating heavily, and the predictions are nowhere near as high as they used to be (with the win7 RC i got 7 hours or so in practical use)
the Launch Manager software is not really working, when i unplug i dont see the battery logo come up on screen like i used to when i unplug, and instead get random changes in brightness and beep sounds when nothing seems to be happening (i think thats related to the optical drive management software) the other touch buttons, like wifi do show a logo on screen when clicked, but the battery button does not.
in the time i have spent writing this post, the battery indicator has predicted 5 hours, 5 hours 30 min, 7 hours 30 min, and 6 hours, all between 85 and 83%. i know it fluctuates some because its calculated based on usage, but this is way more than it ever did before.
in addition i cant install the VGA drivers from acer because it says my computer doesnt meet the minimum specs when i try to install.

How do I make the long led on the front of my Timeline work? It becomes all red only when it is charging, but if running on battery I am not managing to have it work, i.e. to have it indicate how much battery i got left...

On my 4810TZ with Vista I was easily getting 8-9 hrs of battery life, but once after installing Windows 7 its hardly 6 hrs. I have installed the latest ePower Management, Optical Power Manaement softwares. The drivers are the latest for the Windows 7. I have not updated my BIOS, a little reserved about that. The display is at minimum brigtness, the Optical drive is truned off, so is the WiFi and bluetooth, but still just near 6 hrs.

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..

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

I did a clean install of Windows 7 ultimate 64bit a few days ago.
All is fine except one major issue; My battery capacity dropped to half of that in Vista. I am now lucky to get over 3.5 hours. In Vista I had an average of 6-7 hours.
What could be the cause of this? I have updated all drivers and empowering software. I also installed the Vista version of the Optical Drive Power Management just to see if that was the cause.
Anyone else experiencing poor battery times in W7? Is 64bit known for reducing battery times?

Is there any way to disable the blue LED that stays on once the battery is finished charging? It only stays on when connect to AC power. The light is very annoying in the dark.
If it makes a difference, I'm running windows 7 64-bit.

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?

One is marketed as business-grade, another is consumer-grade. Both look very similar and I am not sure if the materials used are any different. So tell me, as I am preparing to buy my next laptop.

For the past few weeks my DV5 has been behaving oddly when booted up from a cold start. The fan switches on producing an incredibly annoying rattle and squeal that almost sounds as if a bearing has gone in it. It's the same noise you occasionally hear from desktop fans that are clogged with dust and gunk.
It usually lasts for only a few seconds on initial bootup and is all over by the time Vista loads.
However, this laptop spends 95% of its time on my desk in my dorm room, residing on an improvised laptop stand for better cooling. I took it into the shop I bought it from now that I'm home and whilst they were happy to look at it, it just wouldn't replicate what I had been describing to them when they were listening to it. Murphy's law I guess. Anyway, they thought the only way to sort it out would be to leave it with them and they would try it daily till it it reared its head. Not knowing how long it would take to get over its stage fright (and needing some information off it) I declined that offer!
Has anyone noticed similar traits or symptoms in their machines? If so, how did you remedy it? I'm really tempted to pull it apart myself but it is only 7 months old so well within the warranty period that I may put in jeopardy.

I just got a new Dell XPS m1530:
2.5 Ghz
4 Gb RAM
300 Gb HDD
Geforce 8600
Vista Premium
I noticed that I can hear the hard drive spinning (like that little clicking sound it makes) almost like 70% of the time. Is that normal? I tried killing off some applications but it doesn't stop! Is there any way to find which application is doing this, is this even normal?

I have been trying to read thru the gazillion posts in the 14z owner's lounge - but there are too many! Anyways, I have decided to sell my ASUS G50Vt so I'm thinking about a Studio 14z.
About the only drawback I can think of is several reviewers have commented that the keyboard flexes too much.

I have a brand new DV7, and I've noticed that when I insert either Blu-ray or DVD-ROM disk, the computer gets very bogged down for about 5 minutes, and there's no recognition of the disk being there. There's no disk driving "whirring", and I can't explore the contents of the drive. Then, 5 minutes later, the drive whirs up and and the computer seems completely normal. This is bascially an out-of-the-box problem in terms of possible spyware, virus, etc. It's as if the insertion of the disk puts it in a coma for 5 mintues.
