powerapplet_tray 2.2

powerapplet_tray is a battery monitor tray applet that I wrote. Quirky currently has version 2.1.

It was reported on the Lupu 5.0 forum bugs thread that the battery tray applet blinks when the battery is low, even when it is charging -- which is an annoyance factor.

Lupu uses Jemimah's Vattery applet, however it occurred to me that my powerapplet_tray has the same annoyance. So, I fixed it, the icon will only flash if charge is less than 10 percent and battery is not charging.

I have uploaded it to:

The powerapplet shows up on my desktop PC, which seems a bit silly. Is this intentional? It isn't supposed to try to detect whether or not it is needed?

re powerapplet not needed
I'll check that. It isn't supposed to.

Powerapplet_tray and APM
I just checked the code. For an ACPI system, it does check for existence of a battery, if none then exits.

However, the APM code is not properly developed. It doesn't exit if no battery. I need to develop this further on an APM system.

powerapplet_tray error
I have a HP550 laptop.

It should display a battery indicator but this has been missing in all puppies since 4.3.1 (lupu, wary, quirky, squeze/dpup) under jwm

The diagnostics are:
