Battery not wanting to charge

[Laith]

As the title said, my dads ASUS A52F refuses to charge. It dosen't charge anything. I bought a battery some months ago on eBay, didn't work. I bought another one from eBay(not the same seller) and the same result happened, it didn't want to charge. Note that it dosen't charge the original battery either. Is this a problem with the computer or the batteries?

Hello Laith mate sounds very much like the charging circuitry has gone south. First up I would check the terminals for signs of wear or arcing or straight forward damage. If there are no visible signs extrenally you may have to go looking inside the machine to see if there are any signs of scorching on the PCB's or dry joints.

You may need a multimeter to test the rails in that circuit too.

Is there a guide that goes deeper into this? Because i have no idea about a laptops battery department etc.

Also, you might want to try this if ICIT2LOL suggestion doesn't work. It's from an older thread regarding a similar problem.

> Disconnect AC
> Shutdown
> Remove battery
> Connect AC
> Startup
> In Device Manager, 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).
> Shutdown
> Disconnect AC
> Insert battery
> Connect AC
> Startup

Yes that is worth a try too Laith the charging circuitry is almost certain to be on the board so hence why i suggested looking for any scorch marks or maybe dry joints.

To be honest I ahven;t had much to do with that particular issue it could be something as simple as a detached connection form the power jack or actually within the charging circuitry which of course regulates the charge rate ie a flat battery will charge quite quickly at first then slow down to almost nil when full - just being topped up to keep the required voltage and capacity.
See my ditty that you probably know close the first windows and click Sensors and then scroll down to where I have in the pic of my machine here.
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
See this for the rail voltage info
Power Supply 101: A Reference Of Specifications - Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
Disregard PART B:
