i was having this wierd behavior of my laptop where battery woudnt charge above 6%, ive tried most of the "solutions" on the web, but none of them worked.
-Desinstalling Microsoft's ACPI-Compliant control method battery
-Doing a vista clean install
-Restarting/Removing/Plugging the battery from the laptop with the system running and shut down, and all sorts of combinations between.
-Trying different AC (from dell, some of my friends have got some dell systems, i tried a m1330 AC)
-Tried to find a battery calibrator, but was unsuccesful, and even tried to downgrade my BIOS, but couldnt because my battery wasnt charged above 10% (thats a requisite to flash the BIOS)
NONE OF THOSE WORKED.
So i called dell, they told me to go to the BIOS, tech guys told me that the problem could be figured out there by 2 ways, it'd either:
-Recognize the AC adapter (in due case, it was a battery problem) -Or it wouldnt recognize it (in which case, it would be a MoBo or a AC adapter problem.
Turned out it recognized the AC adapter, so next step was to send me a new battery, since i had a 6 cell battery (which the dell guy confirmed after i gave him the serial number of the battery) i expected to receive a 6 cell battery replacement, but no, lucky me i received a 9 CELL BATTERY INSTEAD, free within warranty period (system is only 7 months old) so yeah, im happy, and my battery is charging again.
Everything is fine, so i thought i would share this info for you guys.
One thing to get in consideration: The embedded battery health indicator might not indicate that the battery is healthy, since my faulty battery had 5/5 green lights when i tried to check the health but was still faulty (my new one has 5/5 health lights and works wonderful)
When I unplug my laptop from the AC adapter, Acer's ePower system automatically dims the LCD brightness to a setting that is 2 levels above the lowest (and 7 below the highest). However, when resuming the laptop from standby, I noticed that the setting is increased to 4 levels above the lowest (and 5 below the highest). I'm kind of a stickler for these sorts of things and would prefer for Windows not to change the LCD brightness if the ePower manager is supposed to be handling it. Is anyone else noticing this, and if so, have you corrected it somehow?
FYI, I should mention that I recently downloaded an updated version of Acer's ePower management system from Acer's support website - this updated version corrected an error that was occurring where my optical drive wouldn't "wake up" after ePower management shut it down, so I would prefer not to downgrade.
I'm frankly a little confused about where exactly all the Acer-specific power options are located. What is the difference between ePower and PowerSmart? Or are they the same thing? I could go on, but I think I've raised enough questions.
I was just wondering since battery life is lower on an MBP running vista, and the MBP is one big heat sink, is there an alternative to SMCfan for vista that works with the MBP? And what is power management like on vista for he MBP? I think i"m finally going to break and get one
I know of course that the current Sony utilities are not really meant for Windows 7.
However, does anyone have Windows 7 RC with the VAIO Power Management utility installed?
If so, do you also see the issue where the PM plan is not called 'VAIO Optimized' but rather something like 'SPMResMui.dll,-100'? If you do not see this, could you please tell me the version of VAIO Power Management you are using?
I have a new Inspiron 7000 series that I'm setting up. I have a restore app running to download a sizable amount of data from my old backup to this new computer.
Although I have the laptop plugged in and told it to NEVER sleep when plugged in - and I adjusted the hard drive (advanced power management) to stay awake for 120 minutes, it still seems to be going to sleep after a short (less than 1 hour period of time).
I have to hit the power button and wait for the screen saver, then I swipe it out of the way and must login to my laptop. The restore application stops running when it goes into this sleep mode.
Frustrating as my settings all seem to imply the system should stay awake.
My new Lattitude laptop powers back on (sort of) when in either sleep or hibernate modes, but I have to power off in order to get the computer to start. Usually happens after a few hours of being in either mode. Does it have something to do with power management?
Has anyone noticed that Optical Drive Power Management occassionally stop working, i.e., pressing the eject button on your laptop, Windows does not detect your optical drive? Does anyone know how to get Windows to detect the drive, short of restarting?
(my OS is Windows 7 Home Premium 64. I am using Optical Drive Power Management for Windows Vista Home Premium 64 - I just installed the program in compatibility mode. Before anyone suggests this is the cause of the problem, I was experiencing this same problem in Vista Home Premium 64 and was hopeful that Windows 7 would fix it...)
Ideapad P 500 Touch - What driver do I use? I tried em8.08.0.2.4 driver. It will not work. It also has caused an error using my function keys on my key board. Error message:
"Compatibility issue between your power management system and Windows Your power management system isn't compatible with this version of Windows. The model name of your power management system is Lenovo ACPI-Compliant Virtual Power Controller."
I have since a few days my Power managment driver which doesn't recognize the battery any more.I have checked in the Windows Device Manager, which says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".Can it be related to a very recent Windows update I have made? (I'm on Windows 8.1)
I bought 2 of these in oct 2011 for my twins going to college. My daughters has had no problems. The other one died in may 2012 and was repaired under warranty. It died again in November 2012. I was able to get it running by removing the battery and disconnecting the cmos battery and letting it sit for a while.
It happened again, and this time I can't revive it. I want to add that I think there was something wrong when we got it back from repair. The battery icon for the Lenovo power management did not work, but the windows one did. In hindsight I think this had something to do with nvram problem I have since heard so much about.
I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. At least my laptop still will not make it through the night in sleep mode.
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops. Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.
My Bluetooth keyboard goes to sleep after a period of idle and it takes 15 seconds for the Acer Aspire 1810T to wake up and notice the Bluetooth keypresses.
However, I found out my Bluetooth keyboard works reliably when I have a second Bluetooth device connected and active at the time (such as either a headset or bluetooth tethering to a cellphone as modem), the computer doesn't have a 15 second lag in noticing the Bluetooth keyboard again - the keyboard works almost right away even after being unused for sometime.
So that means the culprit is in the power management on the Acer Bluetooth module. Is there a way to force the Bluetooth module to never go to sleep? Any checkbox somewhere, a register setting? Even going as far to purchase a different Bluetooth driver? Or any other option? Sometimes the sleep is useful, but it definitely isn't useful with the Bluetooth keyboard. This problem does not happen if I use an external Bluetooth dongle.
(With BatteryBar Pro, I notice that power consumption falls suddenly whenever the Bluetooth module goes to sleep when the keyboard goes idle for more than 30 seconds, and at this point, it has difficulty 'waking up' when I start typing on the Bluetooth keyboard. But the problem also still happens when the laptop is plugged in!)
Round 1 was the GPU and thanks to that ordeal I made my share of posts in the venerable "Vertical Lines on Reboot & Crash & Vertical Lines" thread.
To insure I wouldn't have to go through a mobo swap again, I also did the infamous Cu Mod - which, btw, worked flawlessly and I still support the concept, regardless of which revision nVidia GPU you may have.
So talk about my astonishment when my 1330 just powered off instantly last night while I was doing some 3D work (*and* charging the battery...). At first I thought it was an OS glitch but after noting that I couldn't power the 1330 back on, I realized I was dealing with another issue.
Round 2: Symptom, diagnosis & prognosis:
>1330 will not power on and the external PS's blue LED is not lit.
>Connecting the 1330's PS (adapter) with the 1330 causes the PS to immediately switch off (fail-safe circuit).
This is easy to determine because the infamous blue LED goes out and stays out until you unplug and replug the adapter to the AC outlet (mains). Reconnecting the 1330 with the PS causes the PS to once again switch off. And so on.
>Hence, my second Mobo replacement is on order... sigh.
There's the slight chance that it's only the so-called "charger Board" which is actually connected to the mobo (see my pics - link in my sig. below) but the last time they replaced my mobo, they replaced the charger board along with it.
I have a Dell Vostro 1710 laptop that was purchased in December 2008.
I am currently having problems however with the battery/charger. The battery does not charge except when I first plug it in. The Power Meter icon shows that it is charging but only for up to 10 seconds, then the message then goes to "On AC Power"
I first noticed that the battery icon on the taskbar in Windows XP PRo SP3 was saying "ONn AC Power" but not charging. Sure enough, it wasn't charging. My colleague who has the same laptop purchased at the same order but does not have an issue.
I have done all the things you normally do to troubleshoot a battery including reboot, check for software updates, swap the battery with my colleague, swap AC adapter, even replace the battery with a new one yet I still have that issue.
I have now noticed that it doesn't appear to be anything to do with Windows at all as when I power it down, plugging the charger in brings the charging light on for approximately 10 seconds, then the light goes out and the laptop doesn't charge.
This morning I tried a different battery that does charge into my laptop and had the same issue, which discounts it being a battery issue I think. I also tried downloading updated drivers from this website but again no joy.
dell xps m1210-worked fine forever-few weeks ago intermittent failure to show charging when plugged in-jiggled-twisted-would charge. last week same issue-no amount of jiggling would produce charge indicator. took to fairly well rated shop after research re installation of new ac jack-after done no difference. they find power enters at jack and then they lose it on MB somewhere they cant seem to reach to test.
I have read guidelines of battery maintenance. It says the best is to keep charge level of the battery at a certain level: 40% for storage, around 80% for standby. I am using same levels for my office laptop Lenovo T400. It is set via Thinkpad Power management utility and works marvelous! Hovewer I was not able to find similar settings in Acer Power management SW. Vista doesn't have that either (as it seems to me ). My main idea is to keep the battery attached and serve as a standby power backup, but minimize charge level to 40%. It is sufficient to protect against short power interruptions or roam around the house from one socket to other.
Last Friday i received my new Studio 1749 with i3. As told by the documentation I put in the battery, put the power cable in the ac-adapter, pluged the AC-cable into the laptop and then pluged the ac-adapter into the wall outlet. I booted the laptop and once I was on the windows desktop had a look at the battery symbol. It showed that the laptop was connected to external power and that the battery was being charged.
I wen't away from the laptop to let it charge the battery for 12 hours as told by the documentation. After two hours i came back to have a look at the laptop and it was off. Curious I turned it on again. After booting up it showed the battery at 60% and the laptop running from battery. Yet the ac-adapter was connected to the laptop. I hadn't changed anything. I pluged the adapter cable in and out, but it wouldn't recognize that the was external power available. Turning the laptop off an on again didn't work either.
Now I feared for the battery. My guess is that at one point it started to run on battery power even though it was not charged for 12 hours. Then when the battery was depleted the laptop shut down. This might have permanently damaged the battery!
I guess as soon as the laptop was off the ac-adapter charged the battery again, and when I came in it was just at 60%.
So I turned it off removed the ac-adapter, removed the battery, put the battery back into the laptop pluged the ac-adapter back in and booted up again. Now it showed it was running from external power again. All fine. It charged the battery as well. Actually it charged the battery up to 99% and then out of nowhere the battery symbol changed and it was running from battery AGAIN! Even though it was still connected to the ac-adapter. This happens all the time. It is reproducable.
So I thought something might be wrong with the ac-adapter.
I powered down the laptop and removed the battery. Now with only the ac-adapter connected ,I tried to start the laptop. The control lights above the keyboard came on for 2 or 3 seconds and then the laptop turned off again. Trying to hit the power button again after that didn't give another reaction.
Conclusion: The laptop won't run just on external power with no battery in the battery bay.
I put in the battery again. AC-adapter still connected. Hit power. Laptop starts to boot. Then while booting I removed the battery. Laptop keeps on booting - finishes booting - runs nice and well at full speed not missing the battery - FOREVER.
So it won't boot with the battery removed, but it will run without it flawlessly??? Strange isn't it?
Next test: I put in the battery again while the laptop is running from mains. And now it charges the battery again until the point... you already know... it "forgets" that it is connected to the ac-adapter and starts running on battery power. So now I boldly removed the battery while the laptop was running. After all it was still connected to mains/ac-power.
I have a Inspiron n5110 laptop and for about a month it had a problem. It works fine (battery charges as usual) until a power drop (even for a second) occurs. When power comes back battery does not start to charge. It gives a error message "AC power adapter type cannot be determined"...
I suspected the fault may be with the power charger/adapter and searched for new one in the store. But there I came to know compatible adapter for my 15R laptop is a 90W adapter. [URL] ....
And I got a 130W adapter when buying this laptop. So I thought they must have switched it by accident and it didn't bother me since it worked fine until now. But according to store, the adapter I'm using now does NOT supposed to be compatible with N5110
This is what I have now : [URL] ....
I have a working 90W dell adapter from my friend and i tried it to my laptop. It also gives the same error as above except my laptop identifies it as a 90w adapter and asks for a 130W adapter instead(When my adapter is plugged-in it doesn't even identify it as 130W as you can see from the image).
It started with a faulty power cord with bad connection that resulted in interrupted power supply (after the slightest movement of the power cord computer showed the battery icon and the screen backlight dimmed - as if there was no power).
I managed to deal with that just fine until the computer started a bad habbit of draining the battery and running out of juice when left ON overnight with the power cord connected. SOmehow it lost the power connection even when I didn't even touch it.
I still didn't pay much attention to that until about a week ago it refused to turn on at all. It does not charge the battery, insted it makes a strange ticking noise, sometimes the charging light flashes sometimes it's constantly on, indicating that it's charging when it really isn't. Whith battery removed, it still won't turn on. It turns on for a split second and then it's off again, followed by that strange ticking sound.
A opened it up, removed all the removable components from it (HDD, DVD drive, RAM, CPU FAN, battery) and still the same wierd behavior. The ticking sound comes from somwhere under the power button, I can't precisely locate it but it's pretty loud.
As a computer it still works. I know that because when there was still a little reserve left in the battery it booted up until the Windows dektop before it ran out of juice. I think with a fully charged battery it would work 100% fine. But the problem is that laptop itself isn't charging the battery anymore and the AC is not provided directly to the system either. So I can't use it anyway.
Some sort of power supply subsystem must be dead but I am afraid that it's integrated in the motherboard. And if that's the case, it would cost a fortune to replace.
Do I have chances of cheap repair that does not involve replacement of motherboard?
I bought this inspiron 15r 5521. Its approx 2 year old. There was warning in battery status in the PC checkup. Few days afterwards the laptop did not start up. I searched and did a hard reset..BUT when i shut it down or hibernate . again its like dead and i have to plug in the power cord for 20 min and do a hard reset to turn it on . It also happens that if i shut down while the power cord is plugged and i take it out and again plug it , it stops charging..(again need a hard reset).
I have a T440P, Up to recently, I was in Windows 7 with Lenovo Power Manager set with threshold charging limited at 63%, So far so good. Now, Windows 8.1 has been installed from scratch (Not an upgrade).
The laptop with windows 8.1 still stop charging at 63%. But there is no Lenovo Power Manager available for windows 8.1. I don't find any solution to deactivate this limitation...
