Laptop Battery not charging

Hiya,

I have a laptop and the battery is not charging at all, I am assuming the battery needs replacing but find it a little strange that it never charges not even a little. Usually when laptop batteris died I thought they would take at least a little charge.

I dont have a spare battery to try.

Just wondering if there is anything I should try before ordering a new battery?

Thanks,

Try this software CPUID HWMonitor on it. It might tell you something about the battery (I forget as I'm not on laptop at the mo').

It could be the charging circuit in the laptop. Can you charge the battery on another machine?

I dont have another laptop with the same battery unfortunately

How old is the laptop? When the batteries are totally goosed the laptop will switch off immediately when you unplug the power cord.

Sorry to jump in.
I have same problem with a Dell Inspiron 1545, after a couple of years the battery wouldn’t charge, went and bought a new battery to no avail, came to the conclusion it is the battery charging circuit or the power pack. So now I just use it plugged in the mains. Not worth spending money to repair the battery charging circuit even if that were possible for a chaep laptop, but would like to know what else I could have done at the time.
Just run CPUID HWMonitor and got these results;
Old battery

Assume that if you remove power from laptop it shuts down.
Lithium batteries need regular cycling from full to empty. Otherwise they can become resistant to charging.
Problem could be charging circuit or battery. Not easy to diagnose Obtain replacement from amazon, normally able to return

This advice is incorrect. The lifetime of a Liion battery is measured in charge cycles, a cycle being going from full to empty. Your advice would shorten the life of a Liion battery.

I think the Charge level = 0% means it's not getting charged so you are probably right that it's the battery charging circuit faulty.

Also the Capacity seems very low. Mine shows:

Designed Capacity 88800 mWh 88800 mWh 88800 mWh
Full Charge Capacity 39782 mWh 39782 mWh 39782 mWh
Current Capacity 39782 mWh 39782 mWh 39782 mWh
Wear Level 56 % 56 % 56 %
Charge Level 100 % 100 % 100 %

After four hours on charge the new battery shows;

Designed Capacity 32560 mWh 32560 mWh 32560 mWh
Full Charge Capacity 32516 mWh 32516 mWh 32516 mWh
Current Capacity 784 mWh 784 mWh 784 mWh
Wear Level 1 % 1% 1 %
Charge Level 2 % 2 % 2 %

Compared with your results we can safely say that my pc’s battery does not charge due to the charging battery circuit being defunct!
