Lenovo battery not charging

Due to the nature of the lead acid battery it rapidly adopts a ghost or surface charge effectively fooling alternator regulators into falsely thinking the battery is nearly fully charged. The older the battery is the higher its internal impedance and the worse the situation is.

A vehicle alternator, whether on two or four wheels is not designed to recharge a battery and mostly is incapable of doing so. Vehicle ownership is still a task for a person who owns a battery charger and knows how and when to use it.
The vehicle alternator is designed to provide current for the vehicle electrics and to keep a fully-charged battery, fully-charged.

The first stage is to charge and test the battery and the second stage is to carry out a thorough visual inspection of the vehicle charging system. The third stage is to test the performance of the alternator with appropriate test gear.

Lenovo has their trouble shooting for this at their web page.

here is their brief info.
===================

Please follow the steps below to check your battery.
What can I do if the battery does not recharge after the power adapter is connected?

1. Check if the charger's indicator is on. Check if the charger's plug is fully inserted.
2. Check if another standard battery can be recharged in your device.
3. For some devices, you need to charge the battery for 5-20 minutes or until the charge level is 3% or higher before charging information can be displayed.

Note

1. Different versions of the operating system may have different menu option names.
2. Different versions of the software and features are available for different device models.

well this is a hardware problem.in this case your charging stage is not work.i am showing you a picture in the yellow marking fat 's are shorted if you can change these components the issue will be solved.sorry for bad english.

This sounds like your battery is consumed. Like all rechargeable battery's they have a certain lifespan. Its also worth taking the battery out and check the contact on the battery.

first thing you should check is the AC Adapter voltage output and Amperes that your computer requires.

if all ok, try this:plug in your AC adapter to your computer in a switched off position. wait for an hour or two then turn on your pc and check whether the battery has been charged or not. if not, then the battery is gone but if it's been charged and drains so fast while the computer is on then you should buy a new battery.

Most of the mouses have a kind of switch and when opened, there are 2 batteries. you can replace them with other rechargeable batteries

If the battery is charging up to 73% it means one or two of the rechargeable cells is exhausted, the battery will need to be replaced.

Was the adapter you bought directly from Lenovo? I just know that dell builds in a chip to detect the adapter, if not original it will not charge the battery. I do not know if it's the same issue.

It could be a faulty battery or a faulty charging circuit.
Rechargeable batteries have a finite number of charge and recharge cycles. There capacity reduces with age until they reach a stage where they won't charge at all.

I think that you should check whether your battery is not licking and also try to charge your battery in
any other NOKIA phone, to check whether your battery is working state or not and if its working then also also try to check your charger and finally phone using another battery.
