Leaving a battery in an unplugged external charger can lead to some battery drain.
HOME / Is there still current after the battery is unplugged - VLM Commercial ESS
Had one router where a signal light would light up for 30s after unplugged. But it''s outlier. hose has to fill up before the sprinkler can function. once you''re done watering the lawn you turn the water off but there is still a little bit of water left in the hose that might trickle out of the sprinkler and will definitely get you a little
After the battery is fully charged, it shifts to maintain mode where the charging current reduces to as low as 13 mA. I noticed that even after I unplugged the charger, while still connected to the battery, the charging current didn''t fall to
After I unplugged the PC some LEDs on the GPU is still glowing also with my monitor''s power button glowing for a while after unplugged. IIRC electric speed is 1% of speed of light. there is still the potential for some current/charge to remain in the electronic device. Reply They work basically like a battery which charges up while
Every now and then, if I finished charging my laptop and unplug the cord (doesnt matter if the laptop was dead or alive), the battery status would still persisted on
I have replaced the CMOS battery with a brand new Energizer CR2032 (tested and working). I tried setting the SATA Mode to Disabled. I set the clock in BIOS and also went into Windows and synced the clock there. I took the CMOS out, used a jumper on the CLRCMOS pins, and let it sit with no battery for hours.

Note: If you''re still getting random shutdowns due to power issues, I''d assume your charger isn''t supplying enough power during demanding tasks so I would avoid them until you get a replacement battery. If there are no random shutdowns, you''re safe without a battery.
One of the fans didn''t work, so I bought a new one and tried to replace it myself. After disassembly and reassembly (which was hard enough due to a broken screw), my laptop only works when the battery is unplugged. (Via AC) When the battery is plugged, I get 3 red blinks next to the power button... - Lenovo Yoga-900-13ISK2
I believe I updated my bios to "A08"(?) prior to installing windows 10, unless there is new version out. When the laptop is plugged in, the battery icon stays at a 100% charge. When it has been unplugged and unused over night, the battery will have lost it''s charge. Then when plugged in, the battery icon will show that it is slowly charging.
I played last nite and charged it overnight. confirmed both batteries at 100% before I unplugged the extended battery and packed it up. If I still see a drain Ill try this, thanks. The Q2 battery drains even when there is no external battery plugged into it. A place for all current and future owners of Keystone Travel Trailers and Fifth
It shouldn''t explode and a do a powercfg -batteryreport to see how worn the battery is. It could be a replace soon threshold to a it dies within minutes of being unplugged scenario. If the first - ignore until the laptop dies quickly. But this is basically a warning that your laptop battery needs a replacement ASAP.
Being informed and conscientious about what you plug in and how long you''re leaving it there can help you save money and protect the environment at the same time.
LEDs use very little current so it can be powered for a short period after the power is disconnected. This is also why when resetting an electronic device by removing the power,
Fixes to Solve Laptop Shutting Down When Unplugged. Before trying the fixes, examine the battery icon on the taskbar to see if the battery status shows a “plugged in”
There is a small risk of fire. Be vigilant if the battery starts swelling or if you smell a strange electrical smell those are the warning signs. I''ve only seen one laptop battery catch fire. It was in a cardboard box to shipped back for a warranty replacement and it burned a little bit but not even though to start the box on fire.
There''s a bigger reason here- if your router failed because the IP address was fucked up on the core network, the way you resolve that is turning the device off for a while and routing tables update
If by any chance there is a fault, or it has been wired up wrong, or plugged into an incorrectly wired (reverse polarity) wall socket some wires may still be live. The appliance would go dead with all lights off, but electricity could
After that, click on OK and Apply buttons to execute the changes. Now, you can check if the laptop battery says 100 but dies when unplugged. Fix 3. Reinstall Battery
After plugging back to DC and installing fresh Windows and drivers directly from Acer''s site everything works just fine, except for the battery. It is detected by the Windows,
The most obvious reason for a laptop shutting down immediately after unplugging the power cord is that the battery might have gone bad. However, that isn''t always the
But if I were you I''d test myself with a meter inline between the battery and charger while it''s unplugged. S. samven. Joined Jun 11, 2003 Messages 1,281 OK so I went out to the garage and hooked up the meter on the 200 microamp scale and there is 0 current flowing with the charger unplugged. Its a Schumacher 2A charger/maintainer. WobblyElvis.
In short, even if you remove the battery from the car, there is still a good chance that the airbags will still work shortly after removing the battery. The operation of an airbag relies on electrical current from the vehicle''s battery, which
Windows 11 task bar icons shows 100% charge. I did confirm this by generating battery report, it too showed 100% charge. But when I unplug the charge the laptop dies. The battery was replaced 1 and 1/2 months back.
Obvioulsy not talking about electronics with batteries, but things like power supplies, battery chargers, and routers sometimes have lights that stay lit for a few seconds after being unplugged. Archived post.
Just because they said there is no battery problem doesn''t mean there isn''t one. Typical reasons for a battery not charging... The battery is going bad and needs replacing. The charger is going bad and needs replacing. A way to test for this is to try charging when the laptop is off. Not hibernate or sleep but off.
When you have a PSU connected to the Mobo, the battery is not used and just there for when there is no power to the system at all. It would probably be beneficial to change the battery (carefully!) with the PSU plugged in but the computer still off.
The house batteries still illuminate the inside lights, water pump etc. this makes no sense to me. I understand that when I turn the salesman switch off a number of things are still drawing power but with that switch off and the negative lead of the battery bank off as well it really surprises me that things are still powered. Any thoughts? Rick
The 30-second rule is still advised in modern electronics. The short answer to the question “Why?” would
I realize it''s not like a typical light switch, but there''s still an on and off. Try turning the light off, then unscrewing it. Does it still stay lit? I''m assuming the circuitry still thinks the bulb is on when you do this. Typically there would be some
Later I continued to use my laptop unplugged and after around 2h noticed the battery to be still at 100%. The Lenovo Vantage showed my laptop as having over 4h of battery remaining; then I have restarted the laptop and it showed 50 minutes left. If there is an update, follow the instructions provided on the official website to update the

A power switch would work. But it sounds like there is a connection being made that shouldn''t be. In an active circuit the circuit is completed by the 1/4" jack going to the amp. If the cable is not plugged in and the battery is still draining then
In reply to # 4328782 by wadsey Is this normal behavior to see any voltage at all after disconnecting the ground from the battery? I disconnected the negative ground from my battery and put a multimeter between the solenoid brown cable connector and various locations on and around the engine, and got 2.8 volts (which has been steadily decreasing since then).
Having said that, many batteries these days keep a hidden buffer so you are never really charging to 100% or fully discharging. Also, most modern BMS will account for battery degradation and attempt to reduce the amount the battery is charged to 100% and also reduce the charging current after 80% to minimise the stress of the battery.
My laptop is a Jumper EZBook X1 the thing is that when I unplugged the charger the battery will drop really fast, it take around 12minute to drain 100% I try to reset the laptop but is still not fix The methods you told me did not work will, the battery is still darning really fast. if you have more methods pls help me out. thanks for the
Yes. There are still components in the laptop charger that uses a "little" energy when it is plugged in. About a year ago, there were numerous commercials on TV stating to unplug your cell phone charger when not in use due to the same
My Advent 5431 laptop is dual booting windows 7 and ubuntu and has a U40-3S3700-B1Y1 battery pack. It says that it is always charging even when the charger is unplugged. Why would this be? When I unplug the power cord it continues to say that it is plugged in and charging but the battery life goes down until it powers off without a warning.
your best bet would be to get the battery examined by a qualified person and/or try a replacement battery first. It is however more likely that your electronics on your laptop is broken. In Linux
The maximum capacity is often a bit above where the OS puts the 100% mark (so the battery doesn''t get charged to full capacity, which is often detrimental to its lifespan) and the 0% mark that the OS uses is the lowest level that the battery can still provide a sufficient voltage for the computer to use, it''s not the actual minimum capacity of
If you are facing the problem where your Windows 11 or Windows 10 laptop turns off when unplugged, even with a new Battery, then this post could be helpful for you. The most obvious reason for a laptop shutting down immediately after unplugging the power cord is that the battery might have gone bad.
Assuming you've zero'd the DC clamp on, it may be supplying a small current. 13mA is okay. See the manual: Maintain Mode: When the FULL CHARGE (green) LED is lit, the charger has started maintain mode. In this mode, the charger keeps the battery fully charged by delivering a small current, when necessary.
The most obvious reason for a laptop shutting down immediately after unplugging the power cord is that the battery might have gone bad. However, that isn't always the case, especially with newer laptops. It should be noted that the battery usually degrades over some time, and the change is noticeable.
If the battery voltage drops below a preset level, the charger will go back into charge mode until the battery voltage returns to the full charge level, at which point the charger will return to maintain mode. The voltage is maintained at a level determined by the battery type selected.
Depends on the charger. A few (such as Apple's charger) detect when they're plugged in and turn themselves off (leaving only a very microscopic current drain) when not plugged in. Most original equipment supplies for name-brand laptops meet US energy-saving standards and draw relatively little current when not plugged in.
Possible reasons: 1. Battery calibration issues: The battery may lose its ability to communicate correctly with the system, resulting in an inaccurate battery display (for example, showing that 100% is actually low, or that the battery remains 0% when it should be charged).
