Notebook Operating System and Recovery

As usual, my Hp laptop has stopped recognizing the charger. This would almost be comical at this point, if it wasn't so frustrating.  I've to "fix" this problem about every 6 months since I've owned this laptop. The laptop doesn't charge when it's turned on and will not show any indication that it even "sees" it when the charger is plugged in. At least it does still charge when the laptop is off. 

I have tried the other troubleshooting tests by running diagnostics and uninstalling/reinstalling the ac adapter and apci battery control in device manager. I do have a 2nd ac adapter and get the same results with it. 

In the past I've just updated the BIOS several times and the laptop finally starts charging. Sometimes 1 BIOS install is enough, other times I've had to install the same BIOS file multiple times before it starts "seeing" the charger. I am currently on BIOS version F.42. The online support (drivers and software page) shows a new bios update available (f.43 Rev A). F.43 doesn't work. The installer has "update" grayed out. In the other threads about the same problem with F.43 not installing, HP support has quit responding. 

So...if anyone has any ideas other than buying a new laptop (getting close to that point and it won't be hp), I'd love to hear them. Also, if anyone has the filename or a download link to the F.42 BIOS so I can try reloading it again, that would be great. The only BIOS file I can find on my laptop is f.41even though I am on F.42.
