Battery Fully Charged turns off AC

Q: Battery Fully Charged turns off AC

This problem started 3 weeks ago.

When battery charge reaches 100% the AC LED indicator is turned off and the laptop runs from battery (decreasing it's performance even selecting High Performance power plan).
If the AC plug is disconnected and reconnected the AC LED indicator is turned on until battery is fully charged again, as soon as the battery is fully charged windows battery notification icon changes from "99% available (plugged in, charging)" to "Fully Charged" and then the AC is turned off and the laptop starts to run from battery again.

I didn't update any laptop specific software nor BIOS.

Last installed windows updates:

Does anyone know how to fix this? I want the laptop to run from AC when AC is plugged in, even if the battery is fully charged.

Thanks!

I have a 2 day old T480s with out of the box OS (Windwos 10) installed.  I've run all windows updates (not the October 2018 yet), and all Lenevo Updates as of 10/11/2018.  When the laptop is plugged in, and reaches 100% charged, it starts acting like you are unplugging and plugging it back in.  It does this rapidly, every second or so until you unplug the laptop.  You can see it in the attached event viewer image.  It alters between: Event ID 105:  Power source change.Event ID 4107: A caller specified the SDC_FORCE_MODE_ENUMERATION flag in a call to the SetDisplayConfig() API This thing is brand new, what could be causing the issues?  Seems like a driver to me as it does charge fine when I let the battery drains a bit.  I know there is a setting in Lenovo Vantage that allows you to change the point at which the laptop stops charging, then also sets a lower limit for when it will start charging agian.  When I do this, and set the stop charge to 95% or lower, the Off/On behavior no longer happens.    Any help would be appreciated it.

Should I do it unpluged or not? Thank you. 

A:Fully Charged Battery should be unplugged or not?

The computer is doing it right. When battery is completly charged, there is no need used the charge from it and then charge again. Hence once the battery is completly charged, the power is used from adator.You can leave the adaptor plugged in and continue working or if you want to take hte computer around then goahead and use the cheage from battery.

Hi,

I have Dell Ispiron 15 3542 and I am surprised that my laptop has been switched off directly even though the battery is 100% charged and even the charging icon is displaying at task bar when the charger is switched on. But red light for low battery goes on blinking and when the power cord is removed it switches off and if switched on the power cord a message appears as "Your battery has met with parmanent failure and needs to be replaced and press F1 to continue and press F2 for setup utility"

I dont know what happened, but today when I turned on my laptop it consistently shows that my battery is 0%

Obviously this isn't true as im using it right now to post, my laptop also shows that its fully charged (The LED light is lighted indicating that it is 100% charged)

What can I do here? I'm quite sure its not a problem of a virus because i've scanned my computer and all. I am using a Toshiba laptop, using the Toshiba powerplan. And if needing more info, I shall provide but I don't think thats necesary for this problem.

Not sure if this will make a huge impact, however.
On my laptop there is this wheel that you can turn to increase and decrease the volume. Yeah, this isn't functioning anymore (found both these problems when I turned on my laptop today)

I have an Acer Aspire V5-571G laptop with Windows 10 installed (there's only an opton for "Aspire Desktops", so I had to choose this, but please not that I'm using a laptop).  Originally, my computer's battery icon when fully charged wouldn't only say it's fully charged like now.  I don't remember what it was exacty, but it used to say something more, too.  I'm not sure if it happened because I always keep my laptop plugged in, but it shouldn't be this because my dad also told me that it's supposed to switch to using electrical power to run rather than the power stored in the battery once it's fully charged and that whether you always keep it plugged in or not doesn't matter (is this true?).  Mine doesn't seem to do that anymore, and it sometimes also shows that it's in "98% (Plugged in, not charging)" mode, and then the charge continues to decrease.  I also tried removing the battery and booting it for a while without the battery, with just the electrical power, and then uninstalling the Battery Driver Softwarea and putting the battery back in and rebooting so it'd install the software on its own; and then I didn't reboot it again, but I did drain and recharge the batter three times, while letting cool down between charges.  But that doesn't seem to have worked.  If I posted this in the wrong section of the forums, it'd be appreciated if someone were to move it to the correct section.  Any help anyone can give me on this...

Replacing my battery on G550. Manual says "Install a fully charged battery." How do I charge an uninstalled battery 

A:Install a fully charged battery

Hi Username12,
 
Welcome to the Community Forums.
 
I don't think this is an absolute requirement for replacement battery to have it fully charged.
It would be expected that it has certain amount of charge to maintain battery firmware when purchased and as all the stocked battery would eventually have depleted on certain degree a period of time.
 
Initially powering it without the ac charger would ensure that it is working fine.
You can simply proceed to check if the new battery is recognized by the laptop, charging eventually within 3-4 hours being plugged in. 
 
Hope this helps answer your query.
Update us how things go.
 
Regards

My laptop has a battery light which tells me when my laptop is fully charged. When it is fully charged (it is green), Windows still says "05 minutes until fully charged" and then charges for another half hour. In the past the light has been reliable, so I believe that windows 10 is the issue. My laptop has also had significant issues with charging. I can confirm this with two batteries. I have an Asus K55VD which I haven't changed the battery plugs in or anything like that. What could my problem be? Here's what I've tried:

-Disabling and re-enabling Microsoft ACPI-Compliant Control Method Battery (no change)
-Turning power saving off in BIOS (did a bit of help with the charging problem)
-Fixing the fan (turns out it wasn't spinning, which caused a range of issues. Helped the battery charge issue a bit)
-Keeping the laptop shut down (didn't help)
-Keeping it asleep (didn't help)
-Keeping it on with the screen off (did help it charge)

Yet I can't find a fix for the battery charging percentage and time issue. Any help would be appreciated.

A:Battery fully charged, but still charging

You won't want to overcharge the battery but allow it to run down a bit often while not seeing the ac charging adapter plugged in constantly. Otherwise the life of the battery will be shortened. As for the 4hr. batteries those will show 3hrs. 52min. of time not a full 240min.! depending on make and model laptop as well as brand of battery. Found that out fast when the need to swap the 2hr. battery that came with an older model HP laptop saw the 4hr. replacement. The new Toshiba 10 laptop however came with a 4hr. battery.

Windows any version isn't exactly the best battery level meter to begin with and shouldn't be relied on as being absolutely 100% all the time. It is afterall still "Software" in contrast to having an accurate physical meter as well as the differences between makes and models of laptops having different power requirements while batteries will tend to see a standard for everything in use! One model will pull a battery down faster simply from having it running then the next! Different cpus as well as the rest of the hardwares will play a role there as well as the individual board designs. Never leave a laptop constantly plugged in while a battery is present as those will tend to get quite warm as well as the overcharge factor to watch for. A good overnight charge of 8hrs. max and if not wanting to see the battery run low and running off of ac a few hours but never constant as that will tend to kill a battery faster.

You can try running an sfc scan to fix corrupted system files.

Or you could try alternative battery meters. E.g. theres one made by a forum member (Bagaria).

I just bought an Inspiron 15 i5558 Signature Edition two days ago, and it won't run if I unplug the AC adapter. It's acknowledging that there is a batter, and it says it's at 100% (but when I hover over it, it says not charging). It recognizes when I take the battery out, so I know the computer can recognize the battery, but whenever I unplug the charger from the computer, it immediately shuts off! The light at the front of my computer (which has a battery symbol next to it) is constantly flashing orange.

I'm incredibly fed up and am about to return this laptop if there isn't a solution. 

A:HELP!! Brand new computer won't run on a fully charged battery!

Look's like the battery is NOT fully charged, but totally flat. Download BattStat and see what it says about the battery and charging. Most likely you should contact Dell about warranty service.

have you made any recent changes to your system? (i.e. new battery or BIOS update?) Did you drop the laptop?

Hello everyone,

About a year ago I bought a genuine replacement battery for my U500. A few months ago, the battery seemed to have gone bad (no charging), and since I was traveling I didn't have time to take it back to the dealer for yet another replacement. Last week, however, it started working normally all of a sudden - or so I thought.

As it turns out, the battery did actually charge (it recharged from zero to 95% in about an hour, and now the icon says "95%, not charging"), but it won't power the machine; if I pull the plug, the machine will die immediately.
I tried taking the batter out and cleaning the contacts, but that didn't seem to help.

Any input on this is greatly appreciated. Thanks in advance.

Shady

A:Battery fully charged, but Satellite U500 won't power up

I think the battery is faulty.
Probably you purchased some kind of imitation product even if the part number would be the same.

Many 3rd party online dealers provide cheap ?china? batteries which are compatible (the battery dimensions are the same) but the performance isn?t the best?

I think you will need to replace the battery once again?

I want to keep the battery on my laptop as healthy as possible. I primarily use my flex 4 when it is plugged into a wall charger, and was wondering if when it reaches 100% does the battery stop charging? I know it says it does not charge, but can anyone confirm that there is no electricity running through the battery when it is plugged in and fully charged? What is the best way to keep my battery from degrading over time? Thanks!

A:Does the Flex 4 battery stop charging when fully charged?

Yes. it does stop charging. All modern laptops have a lithuim-ion battery that is computer controlled.But it is recommended to drain (use) the battery at least once a month to calibrate and maintain battery chemistry healthy.

Is this normal? I'm on an E5-474G. Does this mean that the laptop is drawing power from the battery while it is constantly being charged or it is running straight from the power adapter as in "plugged in, not charging".

Hi all,I have a couple of months old ideapad 720s running win10. Since a few days ago, I am not able to turn on my pc without the ac adapter plugged in. However, the second I turn on the computer, I can take the plug off an my pc works fine just on the battery. The battery is also charging ok, it just won't start the laptop. I don't recall doing any system/driver/software updates around the time this issue first occurred. Also, my energy managment seems to loose "memory" of my settings whenever I turn off the pc and unplug the ac adapter. If the cord stays in all the time while the pc is turned off, the energy managment settings work just fine. So, it seems like a hardware issue to me, but it's hard to imagine what exactly could be the problem, since the battery is charging.

Thanks for the post, I see that your computer is not booting. Kudos to you for connecting the charger and observing it overnight. I would like to assist you from here. However, for accurate assistance, I would like to know the product number of the computer and its operating system.

 

If you recall any updates being installed before this issue occurred, try performing a BIOS recovery, refer http://hp.care/2bXONjA

I would like to know if there are any lights blinking on the keyboard when you try to turn the computer ON. 

Also, do you get any HP logo or any error messages on the screen? 

Please refer to this article for No Boot troubleshooting http://hp.care/2eKbCpt

Also, when you  unplug the charger and press and hold the power button, the charger light blinks white three times, and then the windows logo on the screen lights up.  I assume it powers off again after this. What is you exact model of HP split x 2?   How Do I Find My Model Number or Product Number? Was there any changes made to your system before this happened? Have you tried booting into safe mode to troubleshoot?  HP PCs - Windows Safe Mode (Windows 10, 8) If you can get into safe mode you could try a restore to before this happened. If still have no success please contact HP support for assistance. Please contact HP support at Contact HP Support.  Please let me know the outcome. Thank you  for participating in the HP Forums! We want to help you as well as others who may experience a similar issue as you.

This happened once before when I first purchased the laptop for my daughter.   I called tech support and they had me push a series of function keys to get it started.  I really wish I wrote it all down as now it is out of warranty!  The laptop does not power on nor does it show a light when plugged in.  The screen is completely blank and no lights. I tried the hard reset and no result.  Please help this is my daughters laptop for school.

I bought this pc yesterday and it's the second one that gives me this problem. The screen starts flickering (changing its brightness a bit and frequently) only when the pc is fully charged at 100% AND wired. The thing is increased also when there's a refresh of the image, for exaple when moving around the arrow or watching a video.In battery mode I have no problems, but when I connect the pc with the original psu the problem return. Is there any setting I can tweak to eliminate the problem?Thanks Note: everything is fully updated.

Exactly same problem here. Small brightness changing on its own when notebook operates on AC. With full brightness on AC or on battery no problem. I disabled adaptive brightness in power manager, but problem persists. First I thought, that notebook has malfunction and I returned it to seller (my seller consider it as DOA). Grab another one and it acts the same. I think it is some problem with Windows system / Intel graphics driver, because on battery or full brightness there is no problem. It was also OK, when device was out of box factory new until Windows updated system itself and Intel graphics driver. Tried install original Intel graphics driver and factory reset, but no luck.

Hi everyone,
I need some help. I went to use my acer laptop yesterday after not using it for about 4-6 months and it won't turn on. I charged it and the indicator light says its fully charged but it still doesnt come on even if it is plugged in. I honestly don't think it is fully charged because the light turned blue after being plugged in only 1 hour. Do you have any suggestions that could help me?

Remove the battery and try turning on the laptop using only the AC adapter
