Recent Ubuntu kernels do not boot under battery on my Dell Mini 9
 
I am running Ubuntu LTS 12.04 on my Dell Mini 9
Memory: 991.6 MB indicated
Proc: Intel® AtomIntel® 945GME x86/MMX/SSE2
Graphics: ™ CPU N270 @ 1.60GHz × 2
OS Type 32 bit
Disk 29 GB
Kernels:
Ubuntu 12.04 LTS, kernel 3.2.0-26-generic
Ubuntu 12.04 LTS, kernel 3.2.0-26-generic (recovery mode)
Ubuntu 12.04 LTS, kernel 3.2.0-25-generic
Ubuntu 12.04 LTS, kernel 3.2.0-25-generic (recovery mode)
Ubuntu 12.04 LTS, kernel 3.2.0-24-generic
Ubuntu 12.04 LTS, kernel 3.2.0-24-generic (recovery mode)
Ubuntu 12.04 LTS, kernel 3.2.0-9-generic
Ubuntu 12.04 LTS, kernel 3.2.0-9-generic (recovery mode)
Ubuntu 12.04 LTS, kernel 2.6.32-37-generic
Ubuntu 12.04 LTS, kernel 2.6.32-37-generic (recovery mode)

System works fine except that only the 2.6-based kernels will
boot when battery charger is not plugged in.
Grub jumps to black although "power" light remains on.

I am guessing that this is a power management problem.
I have been doing upgrades thru the update manager.

Is there anything that can check?
Is this the best forum for this query?

Ubuntu Netbook support finished. I suggest an old old hardware distribution. 8, 9, 10 Netbook

I run SalixOS on my Dell Mini9 without any issues, but it's still a 2.6.x kernel. Before that, I ran regular Ubuntu up through 11.04.

I doubt that Ubuntu's no longer offering a netbook remix has anything to do with it, but the kernel version might. I don't have any way of testing that tonight.

Just for grins and giggles, I burned a CD of the latest Ubuntu ISO (12.04 with kernel 3.something I forget exactly what), jacked in an external optical drive, and booted to the live CD while under battery power. My Dell Mini9 booted just fine.

(I know it's not quite the same as installing Ubuntu, but I'm not going to do that. I'm fed up with Ubuntu's antics.)

That does not solve your problem, but it does indicate that a Dell Mini9 should be able to boot that kernel under battery power. Hopefully, this will help a little bit by ruling out the possibility of some global version incompatibility with the Dell.

Good luck.

When can you please tell me the official Ubuntu Netbook Remix. 12,04 in 1018 to run the Dell netbook. Terribly slow.

Ubuntu no longer makes a netbook remix. They stopped about two years ago.

I'm running SalixOS--Fluxbox edition and quite liking it. If you want to stick with a *buntu, you might look at Xubuntu or, even lighter, Lubuntu.

You could also look at simply running a lighter-weight desktop, such as Fluxbox or LXDE, on your Ubuntu.

I thank frankbell for his heroic efforts.

Additional testing shows that booting with the charger attached is successful and,
moreover, I can unplug the charger and get a "init 6" reboot OK.

After a while I noted that the "power" LED remained lit, even though the screen was
dark. So I looked at the file /var/log/dmesg.0 and found that booting
had succeeded. I attach the file, which shows a few oddities, like the

ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared
and

apm: BIOS not found.

Otherwise I see no reason for no raster on the display.
But perhaps I am missing something.

[blush] Burning a CD and booting to it is hardly heroic.

I tried searching for

apm: BIOS not found dell mini 9
and turned up nothing that seemed obviously useful.

Further investigation will have to wait for more experienced persons than I.
