Inspiron battery issue

Advice needed! I am in need of some help please.

I have a Dell Inspiron 1545 laptop which recently was updated to Windows 10. Most of the time it was used as the shack computer with a mains cable attached. Recently, it has been used elsewhere in the house mainly for web browsing. It has an after-market battery pack that is not that old.

My problem is the battery (which started at 30% charged) has gradually lost charge and now shows 0% and the laptop only works when plugged in on mains. Despite adjusting all the battery management plans the battery will not charge! I cannot see how to make it charge at all.

My question is....

Is there a way of making the battery charge, maybe by adjusting something in the BIOS?

WSPR with new Win 8.1 PC

I had a surprise today: my Inspiron 15R does NOT have a touch sensitive screen after all. Dell assure me I did not order, or pay for such a screen  This is not an important feature.

The next surprise was a sort of malware program called "optimizer pro" which managed to install itself and wanted me to buy a subscription to reomve hundreds of errors. A free call to 0800 028 2660 ( the FREE Dell support number) soon had this removed and the PC fully checked remotely. WSPR, Spectran and Ccleaner all installed and worked without issues. Ccleaner is a recommended free download to do the same and a lot more. I run Ccleaner regularly to check PC health.

I tried WSPR on 20m and 10m and the software ran without issues under Win 8.1. A nice surprise with Win 8.1 was that the PC's clock is already sync'd to an internet time server so that timing was not an issue with WSPR. No need to install special software for this purposes.

As far as I can see, Win 8.1 seems to do all I need.
