Replacement Batteries (x2) both giving Blown Fuse (42) error

[jdb333]

Hi, original battery degraded recently with support assistant recommending replacement. Unable to source original HP part, so I found an alternative replacement. The first replacement battery was not recognised by HP Support Assistant other than % and charging status and the battery check returned No Battery (60). HP PC Hardware Diagnostics 1.6.6.0 passed the battery test when the AC charger is connected. However UEFI diagnostic tool 7.7.0.0 returned the blown fuse (42) error. I tried uninstalling the battery items from device manager, removing the battery and replacing etc, but no change. I've also update BIOS to F.14 but still no change.

I then assumed it must be a faulty battery, so ordered another one from a different supplier (Duracell) which appears to be of different manufacturer but is presenting exactly the same problems, which presumably indicates no fault with the battery. I have a spare AC charger, but using that makes no difference.

When the battery items are uninstalled from device manager, battery removed etc, on first reboot, the task tray battery icon animates as if charging for 10-20 seconds, but then becomes static again - not sure if this is significant.

Spent hours now searching for solutions, but nothing and getting desperate, so any advice would be most welcome.

Many thanks

Thanks. I spoke to support yesterday, seems that there may be some damage to the charging port (which seems possible with recent usage) that may be the underlying cause, rather than the batteries - though the original battery had been degrading for some time.
