Battery meter (only) not updating

I have recently installed a new battery on my 5+ year old hp compaq laptop. I'm not entirely sure, but assume the behaviour with the battery meter started then, though there have been some windows updates since then as well.

The battery meter does not update (anything - charging status / battery percentage) unless I right click on it. I don't have to do anything except right click, and can then click away. left clicking doesn't force it to update.

As I have set up different screen brightness for on/off battery, I can tell that windows is detecting the presence / absence of the charger, and as far as I can tell, the battery is actually charging fine. It is just the battery meter in the system tray which isn't responding normally. Also the HP support center

I have already tried re-installing the ACPI-compliant control method battery through device manager and this made no difference. I have also turned the meter off and back on.

I have installed BatteryBar which appears to be staying up to date, so suspect the problem is windows rather than hardware.

Any way to correct this issue? I could get by with the BatteryBar workaround, but would prefer to just use the one that comes with the OS.

Thanks indiacarnie,

I actually found somewhere else where someone had had a similar issues and they re-enabled one of the bluetooth related services (changed from disable start to manual start). I tried that (though for the life of me i can't figure out why it should work) and it seems to have fixed the problem. I'm a bit confused, as i switched that service off months ago, and only noticed the battery meter issue recently. Oh well, it works for now!

For the record, the battery is third party, but then so was the previous one (3 yrs service)
