bootmenu seems to be completely ignoring the item, after updating to the latest version of BackupMenu :\

To determine consumption, reboot once before. A reboot typically eats about one percent. So, reboot, read battery, reboot, back up, reboot, check battery.

Drops of over 20 percent are common with reboots and are false readings.

BM doesn't eat much, I backed up and restored 2-3 times a day with little problem. However, screen is lit, kbd as well, a compressed file system is bein read and decpmpressed, so power consumption is non-trivial.

OK, never cared about that much but one day I realized that and just before I did a backup. So the bad boy was clearly pointed out ...

Oops - guilty of assumption again,
I had assumed the U-boot implementation in Power kernel
would hose the BackupMenu bootup menu.

I have been cautious (Always, when treading the turf of extras-dev)
and worked up this idea I would first buy the insurance of having
BackupMenu
and then install the power Kernel knowing I had a fallback position
before going on to apps and drivers (like fcam/Bless etc).

Thanks for your insight there, cheers.

I completely purged backupmenu, and manually removed the old item files.

Still not working here.

"apt-get install --reinstall backupmenu" perhaps?
Can you give me any specifics on what exactly happens when you boot with the keyboard open?

I searched this thread and saw some discussion about uboot, but I am looking for answer of this particular issue:
Previously I upgraded to titan's v44 kernel-power with uboot included. After not booting up and then reflashing to the stock PR1.3, when the device boots again while the keyboard is open, a black on white boot menu shows up which gives two choices: "Boot from internal flash" and "Power off (when not in charger)". I was thinking if uboot still remained even though restoring to the stock kernel.
That doesn't matter as long as the device boots and things get working.
Then I went ahead to install Backupmenu, hoping to use the backup/restore function and to see if the system crashes terribly . Now the device boots up with Backupmenu's boot menu, and that white boot menu page is gone.
Does it mean that installing Backupmenu will somehow replaces uboot? Maybe I mixed up the concepts so please educate me.

That black and white menu is from "bootmenu-n900", which BackupMenu -does- replace. U-boot doesn't have a menu(iirc), and shouldn't be affected.

Now I understand. Thanks RobbieThe1st.
I am just curious because before flashing kernel-power v44 I had never seen that black & white boot menu, even after installing backupmenu or kernel-power v42 (and below).
