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?
View 1 RepliesI'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%.
the battery of my Dv7t is draining very fast... first i was on vista, it would shut down directly at abt 30% and the battery would last like jus 45 minutes on full 100% recharge! now i moved to Windows 7 and the battery went from 100% to 6o% in just 20 minutes.. also there is a error showing on the battery bar saying "consider replacing ur battery .. the system might shut down suddenly"...what should i do.?the problem starting suddenly like 10 days ago before that my laptop was giving like 2 Hrs back up on full recharge!
View 5 Replies View Relatedi recently installed windows 8 pro on my dell vostro 3550 laptop. i was facing with overheating and battery drain issues. i read in dell forums that dell resolved battery drain issue in bios update and now my current bios version is A10. but problem is i saw in other dell thread that A11 has some flaw in it and not advisable to update and that too previously my bios update failed and dell replaced my Motherboard. so how can i overcome overheating and battery drain issues ?
View 3 Replies View RelatedWhat 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............
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.
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.
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
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 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
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?
I have a studio 1537 with the Ati graphics.
The problem i have is when i power on the laptop i get a warning saying Hit F1 Critical battery warning .
So i hit F1. Then get the option to hit F1 to continue or F2 to enter setup as battery cannot be identified.
So i hit F2 so in the bios i see not battery and it says NO charger detected.
Now my problem is the battery is totally flat if i pull the PSU the system dies . I have changes the power jack as i read the could give trouble.
What I could do next as other than this my machine is perfect. Just a note i also have two spare batterys one 6 cell and one 9 cell and still neither charge
My E530's battery drains 5% per day after power off. I searched online and somebody else complained about similar issue on his Y-series laptop. His problem was solved by plugging off power cord before turning off the laptop. Lenovo also updated BIOS regarding this issue for his model after then.
Yesterday I tried his way and the issue was gone too. Can Lenovo update BIOS regarding this issue?
I also find the power manage scheme doesn't work. It always charges the battery from 96% to 100% in whatever scheme I chose. I tried to uninstall the driver and downgrade the power manager, still doesn't work. I didn't try reinstall the system because it is too time consuming. Does it matter I installed win7 in my SSD?
my HP ProBook 450 lowers the brightness when its on a light screen (say the website background is white, it darkens the brightness) because white screens dont need the brightness ...and vice versa, it brightens the screen when its on a dark page.

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?
Is there a way to find this out WITHOUT turning on the computer?
View 3 Replies View RelatedBeen playing with my 1340 for a day and I have run into a real snag. No BSOD... something almost as bad.... a Memory Drain.
While running IE7, the laptop begins to build up its memory usage as outlined in the performance tools/taske manager until IE is using well over a gig of physical memory and the computer warns me to shut down some applications to free up some memory.
This is only happening with IE7... I have it running alongside outlook, excel, 2 access databases, and music. All the other apps are maxing out at 52-53k of mem use... ie is 900k+ after about 30 minutes of use
I just received my brand new XPS 13 yesterday and followed the quick start instructions. Plugged it in and pressed on the power button. As soon as the power came on, the fan started blowing and is so loud I cant believe this is normal. I decided to convert from my MacBook, so I'm new to Dell... is this normal? It's so loud, I can't ignore it.
View 1 Replies View RelatedI received my E6410 a few days ago and was quite dismayed to find out that I cannot charge peripherals on the powered USB port when the latop is off/hybernated/stand-by *and* the power cable is plugged in. The specs say that the latop has a powered USB port (the one above the e-sata port), and I had assumed that powered USB was the same as always-on. Is that not the case?
I checked a colleagues E6400 today and noticed that the same USB port has a lightning symbol, but that symbol is not on the E6410. The E6400 BIOS also has a setting for "USB PowerShare" which selects whether or not USB charging can be done when the computer is off or hybernated. No such setting in the E6410 BIOS..... Did Dell remove that feature in the E6410?
The Dell D830 comes equipped with one powered USB port at the rear.
The powered USB port is compatible with USB 2.0 connector. When used with a powered USB connector that looks like a bloated RJ45, powered USB port can supply 5V (beige), 12V (blue), or 24V (red)..
They are color-coded and connectors are keyed to distinguish between them..
Has anyone successfully charged an iPod (Touch, specifically) via the Powershare USB port, while the laptop was turned off. When I plugged my iPod Touch, it powers on but doesn't charge.
The manual that comes with the SXPS says some devices won't charge and some will.
I recently came across something regarding the right USB port of my M1530 (the port right below the Slot-Loading Optical Drive and next to S-Video).
The two ports on the left were full (one 160GB External HD and a Logitech V450 Mouse Receiver). When I plugged my other 80GB external hard disk to the right USB port, a pop-up box said that I should plug it into a "high-powered USB port" to maximize its performance or something.
Sure enough, when I was transferring big folders of music files, the transfer rate was very slow. So I plugged the external hard disk to one of the ports on the left, and the speed was back to normal
I have just recently received a new XPS 13 with the new haswell i7 processor, 8gb RAM, 256gb ssd, and windows 8.1.
I really like this laptop, but it makes a really bizarre noise. It happens constantly as soon as its powered on, like a high pitched whirring sound from somewhere beneath the keyboard. It also seems pretty inconsistent, like it flickers in frequency, and when you use programs (e.g scroll through webpages) it gets louder.
Looking to pick up a USB Hub and was wondering if I connect it to the USB port on the right side (not the USB/eSATA port), will it be powered?
View 3 Replies View RelatedMy Inspiron 15R SE which I purchased from Dell Canada in February 2013 recently acted up on me. It was just like any other day, I run the laptop battery down, then plug in the power adapter when its low.
This time however, the laptop just suddenly shutdown (not through Windows, like just up and died). I tried to power it up again and each time, barely 30 seconds after it powers up, it just up and dies.
I had to do work on it so I thought I let it sit for awhile to charge the battery, thinking that I can run it on battery at least. But alas I left it there for even a whole night and the battery did not even charge a drop.
I then tried removing the battery and only running on power adapter only but it won't even start. I have also tried another power adapter but the same issue persists so I can safely rule out the power adapter.
The power port doesn't look damaged either seeing as I have always loyally bought Dell throughout the years, and I really need to get work done (it is my primary computer).
