Whenever I power-down my CPU (not reboot, full power-down) my Ubuntu system will not boot up. No other OS is on the computer, just Ubuntu. Usually reinstalling grub will fix the boot problem. But I don't understand why simply turning off the computer would mess up grub. I have to keep my computer running 24/7 or I have to go through the process of rescuing the system.
I'm guessing it's something to do with the hardware and not the OS.
Ubuntu 10.4 on desktop system.

View 2 Replies View RelatedMy mom's ubuntu 10.04 laptop ran out of battery during a software update and now it will not boot.
When attempting to boot normally, it comes up to the login screen but the keyboard and mouse do not respond at that point. Ctrl + Alt + F2 doesn't work.
Choosing recovery mode also does not complete. The last line showing is "Begin: Running /scripts/init-bottom ... Done." Ctrl + Alt + F2 also doesn't work at that point, although Ctrl + Alt + F7 changes to another screen of text with the last line showing "init: udevmonitor main process killed by TERM signal".
I've tried booting from a 10.04 live CD and ran fsck which did not find any problems on the linux partition. I can also mount the partition and view files.
Running 10.10 After a main power failure I can't boot.
It says:
...........
[sdb] Attached SCSI removable disk
[sdc] Attached SCSI removable disk
[sdd] Attached SCSI removable disk
[sde] Attached SCSI removable disk
and stops.
I get a (initramfs) prompt and have no idea what to do with it.
Allready tried to install 10.10 again from a CD. But it also hangs immediately when it starts to install. The liveCD feature works OK and I can access the hard disk. I tried to update the initramfs with the liveCD but it says I can't write since I have only "read-only" access. But if I do "sudo nautilus" I have full access to the disk.
I installed Ubuntu 10.10 a while back using Wubi. I have it installed alongside Windows XP. Just yesterday the power went out in my house while I was booted into Ubuntu. When I turned my computer back on I still have the option to select Ubuntu or Windows, but now when I select Ubuntu I get right into a grub prompt. Grub used to give me a list of kernals but now it just sits waiting for commands.
View 1 Replies View RelatedMy computer was on when the power went out. I am not able to boot into ubuntu 11.4 install since that happened. I also have debian 6 and ubuntu 11.10 installed on the same machine and both boot just fine.
The machine boots as normal but stops with the line "disconnected from Plymouth". After the machine just sits there with a blinking cursor. I cannot start another terminal. Is my only option to reinstall.
After a power outage Ubuntu fails to boot. How can I resolve this ? Is there a safe mode method to resolve the booting problem?
View 8 Replies View RelatedI was using Ubuntu 10.04 for the last 6 months, recently I have upgraded to Ubuntu 10.10, it worked fine for around four days, Now the problem is When I power up the system using power button, the system do not power up, I tried to boot from cd both Ubuntu and Windows XP, none works, I tried to go to BIOS setup using F2 and F12 (Acer Aspire 5920 model laptop), but i could not, just a blank display appears, here are some symptoms:
1. When powered on - LED indicating pocressor operation glows for a moment and disappears, few other LEDS indicating batter, music play, forward,stop LEDs glows as as usual,
2. Only blank screen appears
3. tried to switch on the wifi and bluetooth buttons, both did not glow indicating it is not working.
4. Paculiar thing is this symptons appears first time, suddenly all stop glowing and after 2 to 3 seconds again the system comes to this state and remains forever.
Questions:
1. Is it possible to be hardware problem?
2. If it a software problem the suspect can be Ubuntu 10.10 version?

I was originally going to install debian on this old iMac G4 and everything was going well. But then I decided, hey wait one second, I could probably find a version of Ubuntu which works on this old iMac, and so... i stopped the installation and loaded the ubuntu 8.04 disc. The only problem is, it will no longer register the boot CD... because i kind of already did the partitioning and nuked the OS X... So now I just see a gray screen with a file image displayed revolving between a question mark and the file finder image.
View 1 Replies View RelatedI'm on HP tx2000 Tablet PC, with nVidia GeForce 6150 Go onboard, 4GB of RAM, Ubuntu 10.04 amd64 Desktop. I keep getting a blank screen after boot splash when I'm on BATTERY POWER. Though I get a blank screen, the screen comes alive when I SUSPEND the laptop by closing the lid, and then RESUME the laptop. Then I can see the logon box and whole desktop.
Usually people get problem by suspending their laptops (usually the screen not coming back after resuming), but now I SOLVE the problem by suspending my laptop. Well like I said I can somehow get the screen right, but I really can't (and don't want to) suspend and resume my laptop every time I boot. Problem occurs REGARDLESS of type of display driver I use. nVidia proprietary, nouveau... whichever driver I use, I get the same conclusion.
I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?
I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.
View 10 Replies View RelatedI'm very new to Linux and recently setup a desktop PC with Puppy 5.2.5. only. I chose to have a permanent install on the hard drive and loaded additional PETS and utilities as I thought needed for my use. Last night after immediately booting up the PC I had a power cut lasting a few minutes. When power returned and I repowered the PC, I found during Puppy's boot sequence it reported an error and remained in what appeared to be a console mode - did not carry through and load my desktop. So I inserted the Puppy CD and booted from that but I'm afraid I'm not familiar enough with Linux to understand how I can get back my original desktop setup and run once again from my hard drive without having to go back to scratch.
View 5 Replies View RelatedOn the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.

I had unplugged my PC last night as sometimes there's storms at night this morning I plugged in PC and the power light is blinking and the PC wont come on at all tried different power cord, same result
PC is a AMD athlon64 3300+ 2.4ghz SiS graphics
probably the power-supply or what?
If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?
Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?
Due to a power outage, my EXT4 file systems (which contain /usr and /opt) no longer mount at boot-up. They are, however, seen by disk utility in Knoppix, so I assume the data is still there and that it's just matter of making a connection to it.

The server was running - Red Hat Enterprise Linux AS release 3 (Taroon). Please let me know if I can try to recover from this error by booting from the 1st CD of a higher version of linux like RHEL5. I ask this because I do not have the old media with which the system was setup. Can the use of latest OS CD cause any problem?
View 2 Replies View RelatedI'm developing an embedded Linux (it is almost over now). What I'm struggling with is the system goes unstable by cutting power source frequently and it does not boot anymore. It even does not perform fsck. The system just has a XFCE with a fixed Qt App autoloaded to display some charts. My question is that how commercial embedded Linux distros (like Wifi AP's management Linux, ...) avoid this problem?

However, after about half or nearly one hour, the box goes out of power and the monitor hangs with the same screen just before the power down. And we have to restart by first powering down the UPS. It is a DUAL BOOT system with WINDOWS 7 and it never happens in there. What is annoying me now is that my friend says, "This is the problem of Ubuntu". I then installed Opensuse 11.2 but again the same thing happens with linux and not WIndows 7. Here are the specs of his system:

View 2 Replies View RelatedI've been using Ubuntu on and off since 8.04, but only last week decided to make a real switch across to it.After installing 9.10 64bit though, my laptop while running Ubuntu just turns itself off at completely random times - it doesn't seem to go through any shut down procedure or anything, it's more like the power's just suddenly cut. It sometimes happens 5 minutes after being turned on, or sometimes 4 or 5 hours, it really is random.I really have no idea where to even begin trying to stop this. I think it must be a software thing because this has never happened with windows or earlier versions of Ubuntu, but other than that I don't know what to do to stop this.I'm dual booting Windows 7 32bit and Ubuntu 9.10 64bit, and this is on a Toshiba L350-D 11-D laptop, which has a 64bit AMD processor.
