Windows 10: Battery charging limit

Should I set a limit to my battery charging ?

:)

 

Plugged in but battery does not charge

If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

Make sure to install all Windows important updates.

Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.


Step 1

1. Shutdown your laptop.

2. Remove the battery.

3. Connect the AC power adapter to your laptop.

4. Power on the laptop

5. Open the Device Manager by typing Devmgmt.msc into Start Menu or from Control Panel.

6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).





7. Shutdown the laptop.

8. Insert the battery.

9. Power on the laptop.

If above suggestions wont resolve the battery charge issue then follow below steps.




Step 2

1. Shutdown the laptop.

2. Remove the battery.

3. Start the laptop with only AC adapter connected to laptop.

4. When you login to Windows OS connect the battery while Windows OS working.





Step 3

Reset the System Management Controller. Use one of these methods to reset the SMC, which controls battery management, battery status light.

1. Shut down the computer and disconnect the power cord.

2. Remove the battery.

3. Press and hold the power button for ten seconds.

4. Reattach the battery and AC power adapter, then start up the laptop.


Hopefully one of the above suggestions will help you resolve the battery not charging problem. If battery still doesn't charge, you may need to replace your battery.

 

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file

 

Laptop battery charging limiter software?

There is no consensus suggesting such restrictions do any good with today's batteries. The "marketing" hype behind it is to prevent the battery from over-heating or worse, over-charging - events that may indeed shorted battery life. But notebook charging/monitoring circuits are not going to let a battery overcharge. And thermal protection devices are going to prevent over-heating. What may seem too warm for us is not necessarily too hot for the battery.

Chargers do NOT keep charging the batteries beyond 100%. And batteries do NOT keep asking for charge current once charged.

You will see some "experts" (cough cough) claim that Li-Ion batteries get too hot when they max out their charge to 100%. Bullfeathers! If that were true, why would battery makers allow it? The shysters... err... lawyers in their legal departments would not allow it!

Charge your battery to 100%. Pull the battery and let it sit on a table for 15 minutes. Does it stay hot?

Modern Li-Ion batteries are pretty smart. And so are notebook charging circuits. Batteries tend to charge very rapidly from discharged up to 70 - 80%. And that's when they tend to get the most heated. As they approach a full charge, they take on a charge at a much (s)lower rate. We see this all the time on our devices. It moves really quickly at first, then takes forever to reach those last few percentage points. That's perfectly normal. But it also means the lower charge rate generates less heat.

If this feature was necessary, why don't all cell phones have it? They use Li-Ion batteries. People leave them plugged in all night long.

See Tip # 6 here (second paragraph).

IMO, if your notebook does not offer the option, don't worry about it. Instead, enjoy the longer runtimes a full charge provides.
