[Bug 120258] Re: Laptop Battery Time Remaining Outrageously Inaccurate
This is especially annoying since unplugging the laptop from power
results in "battery critically low, hibernating now!". with the 9 cell
battery, OTOH, it just says things like "Laptop battery low.
Approximately 7 minutes remaining (92%)" followed instants later by the
indicator claiming 3+ hours remaining.
perhaps not being so quick to believe itself would be in order.

Title:
Laptop Battery Time Remaining Outrageously Inaccurate
Status in Gnome Powermanager:
New
Status in “gnome-power-manager” package in Ubuntu:
Confirmed
Bug description:
Ubuntu 7.04 Feisty Fawn
Hardware is HP Pavilion DV1000 series (specific DV1588EA)
Battery monitor when running on battery reports percentage of battery
remaining correctly, but the corresponding remaining time is often
fabulously wrong (and can swing between e.g a few minutes to tens of
hours in the blink of an eye). /* What I wouldn't give for batteries
that can last 14 hours between charges... */
It looks for all the world like the underlying values are being held
in storage classes which are too small or where value-wrapping is not
being handled quite right...
BTW UBUNTU is fantastic; I'm a convert! Keep up the good work!
