The battery on the Asus N55s laptop is not charging, what could be the problem?

Question

laptops

Hello,
Asus N55S laptop, the laptop was not used for about 12 days, it just stood on the table, the charger was not connected.
After connecting the charger to the laptop, it immediately turned on, without pressing the power button, the time was knocked down in 2011.
Battery charge shows: 0% available (connected, charging). And the charge does not rise above 0%.
I checked the battery wear, aida64 shows 10%.
Also checked via powercfg energy:
Battery: Battery Information Battery
Code ASUSTekN55--52
Manufacturer ASUSTek
Serial Number
Chemistry LIon
Long Life 1
Estimated Capacity 57200
Last Full Charge 51194
When turned on, the charging indicator is constantly on. If you turn off the laptop, it lights up for a couple of minutes, and then starts blinking.
The laptop is about 3 years old. When working on it, the charger is constantly connected.
Actually, the questions are of concern:
1) Why, when you connect the charger, does it immediately turn on? With what it can be connected?
2) Judging by the wear of the battery, it is still alive, but why is it not charging then?
3) Why is the time reset?
4) When discharging the BIOS battery, can there be all these symptoms?

Answer 1

On my ASUS, the blinking of the indicator and the lack of charging appear sometimes with a Chinese high-capacity battery. This is similar to the fact that the data from the battery stops coming. It is treated by juggling the battery.
In your case, it seems that data is also not being received from the battery controller.
It is necessary to check whether the time is lost after turning off the laptop without a battery.
If they go astray, then replace the BIOS battery on the motherboard. Set the current date.
Connect the power supply. Take out the battery, insert the battery. Should earn.
If it does not work, then it is most likely easier to replace the battery, since resetting the error in the battery controller and repairing it will cost almost as much as buying a new one.
The battery controller goes into error if:
- there was a deep discharge
- there was a difference difference in the voltage of the battery cells above a certain threshold
- .... sometimes for some unknown reason (possibly due to the number of cycles or service life)

Answer 2

The battery has discharged below the lower limit and the battery controller has disabled it (thinks it is dead). I had this on my DNS laptop - it is treated by physical intervention (usually) - the battery is disassembled and each bank (usually a couple of 18650 cells) is charged separately from the power supply unit - with a current limit of 500 mA for 10 ... 15 minutes, up to a voltage of 3.4 V ( should be measured). If all banks are alive, the voltage at all will be approximately the same with a difference of no more than 0.05V (if the difference is many times greater, then the bank is dead). The banks will be charged and the controller will turn them back on (it depends on its logic of work - it worked for me). After that, it will be charged with regular charging.
