Hardware :: What To Do With No-booting Power Supplies?
Jan 13, 2010
I have 3 old power supplies, each 3+ years old (out of warranty). One just blew out after a power failure, but it was on a beefy 750 kVA ACP uninterruptible power supply / surge surpressor. It just won't boot a 939 motherboard, but I can not find anything wrong with it. I short the 3rd and 4th pins to turn them on and check many of the pins. They are all ~exactly at nominal voltages. It is as though I forgot to plug in the ATX 4 pin, 12 V cable, but I didn't. Strangely enough, they all boot a very old Athlon XP (32 bit) single core processor on an AGP motherboard. I don't have a good setup to load test them. Is there any trick to rescue them? A fuse inside? Hotwire wire 4 to wire 8? I hate to throw them away as they are nice, quiet, high power supplies:
Antec Neo 480 W
Enermax Liberty 620 W
Enermax eg651p 650 W
Perhaps, I could charge my car battery with one? Install 12 V lighting? Electrolosize water and start an Oxygen bar?

I am struggling to get Debian 8 stable to boot on an apple powermac g5. I installed using guided partitioning, and chose the all on one partition scheme. I am able to select the Debian hard disk from the boot drive selector from mac. I get to the first stage bootstrap, press L for Linux, and then it simply redirects me back to the drive selection. However, after I'm redirected the colors are messed up.

I have just installed Ubuntu in a Windows Vista system. The installation seemingly went fine. After installation, system restarted to boot menu (grub?) where I selected Vista. Vista started fine. I restarted the pc from the Vista login screen. Now the problems started. At grub, I chose Ubuntu. It began to start up, made it through the Ubuntu logo with the dots, some splash screen or wallpaper came up and *bam* the computer powered off. Next I Wanted to boot Vista again. Grub came up for a half-second before power-off.
I tried to boot from the CD again to see about repairing grub or just reinstalling. The installer ran for a second before power-off. Next, tried BIOS boot manager to boot from the HDD again. Powered-off at the BIOS boot manager screen before I could choose where to boot from. Twice in a row. Tried to boot into BIOS to check settings for anything odd. Powered-off within 1 second after I got into the BIOS. Finally, I would hit the power button and it would turn on and then power-off instantly.
I unpulgged my Logitech VX Revolution mouse and the charger (it's fully charged and holding fine). I thought maybe the computer was hot (feels normal though), so I waited one minute. After that, I was able to boot from Grub to Windows fine. I restarted the pc from the windows login screen to try Ubuntu again. Got into grub and just repeated the same process from before with the same results. Nothing works. I waited one minute again, and I was able to boot into Vista fine. I am posting this from Vista with everything connected and working fine.
I downloaded the 32bit desktop version from the "enhanced download page." I burned the iso with the Toshiba DiscCreator software that came with the computer. I've used DiscCreator many times before with great success. Ubuntu was burned to a normal 80min/700mb Maxell CD-R. I'm afraid to reboot from Vista now and find that one of these times, I won't be able to get back in. I installed Ubuntu into an empty 9.77gb partition and formatted it as ext3. Used an empty 1.46gb partition as swap.
Here's my setup:
Code:
Satellite A215 Detailed Product Specification1
Model Name: A215-S5837
Part Number: PSAEGU-03801J
UPC: 883974072095 .....

Out of nowhere my computer will not boot up. I get the message like this
NMI received for unknown reason 29 on CPU 0.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

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 am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.

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.

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?

On 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.

After much research, I have found the solution to my intermittent wireless problem!Whenever the laptop is plugged into power, wireless is perfect, when I'm on battery, wireless is horrible.Here is the fix:
Code:
sudo iwconfig eth1 power off
Unfortunately, I have to type this in everytime I unplug the laptop.

i decided to install ubuntu in my PC,i downloaded the .ISO image and i installed it in my USB. After trying it and all that i observed that i really liked it and i decided to formally install it to my computer in the hard drive. When i reached the partition thing,i selected to dual boot with Vista and select between each them in every startup,when i clicked FORWARD it gave me an error which i did not read(because,again im a noob) so i clicked cancel.
Today i wanted to go through the process again and now really install it,so again i went to the time zone part and i clicked forward but then,instead of taking me straight to the partition phase,it appeard a window saying "The installer has detected that the following disks have mounted partitions: /dev/sda ...." I clicked yes,to unmount this partitions so it took me to the partition thing,once there i selected the option to install Ubuntu with Vista and select between them i neach startup,then i clicked forward and went to the username/computer name process,once i finished i continued to the next part,the installation,but i selected to import all of my WIndows VIsta default user data,after that i clicked forward and went to the installation process,i went down stairs to eat soemthing while it finishes,i came back and it was finished,it asked me to reboot so i clicked in Restart Now.
When it tried to boot,appeared an error saying: Error: no such devide found: #################### Grub load(or something like that) grub rescue: and it was a command line,since there i havent been able to boot into vista or Ubuntu,im really scared because is the first thing related to OS installing ive done,so i booted my USB and ran the trial and right now im trying to find out what to do from that trial version.
I just went to the INSTALL UBUNTU 10.04 LTS application under the System>Administration Menu and found out that in the partition phase the Install and allow to select between both systems in eahc startup option,i dont know what to do,i foudn out that my HD has still all its data(MUsic/Videos/Folders/Programs/ect.)its just that i cannot boot from it. Also in GParted it appears as /dev/sda1/ and a warning icon besides it,also when i go into information, thers this warning there [URL]

I am using a linux kernel 2.6.36 using mips architecture. I have succesfully booted the machine through Flash memory, but it is not booting through nfs. It is getting stuck at the stage where the image starts loading. In short the vmlinux.img file is being copied properly to nfsroot but the image is not loading.

I've been searching the forums for any posts that cover my problem, but most of the booting problems I've found are different from mine.Anywho, the situation:ell laptop, 2 partitions, first is Windows XP, second is Ubuntu Karmic.Whenever I turn on my computer the first loading screen that shows up (is this the BIOS? Excuse my little knowledge of this stuff), before GRUB loads, is really slow. It takes about a minute to load.However, whenever I restart from my XP partition, it suddenly loads fast! And this does not happen when restarting from my Ubuntu partition or anything

I have an old Power Mac G4 400 I'm trying to install Debian 4.0 Etch on (to run a particular program that's ported for this Release).I've twice burned iso CD's for it, but on holding down the C on the G4 I get no more than a blank screen.(no prompt, no installation). Battery still at 4 volts, hours of googling, I have found no information on what is causing this. Anybody out there have an answer for this fellow cyber-sufferer?

Unbeknown to us our son removed the battery and I unplugged the power cord. Instant off! Since then I can't restart. The error is very lengthy but each Control-D brings a reboot but the same sticking point. If I understand correctly I am asked to run setenforce as root. I did this and it does each separate file. How many will I have to do? Is there another way to restart?

I turned off laptop dimming and a few other settings in the power management app, but these are not used so as soon as I watch a film on batteries or otherwise it dims the screen! I tried to search the forums but it won't let me search for terms like ignored or unused

I installed Ubuntu 9.10 in my friends pc. 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:

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.

Does anyone know of a way to determine how the PC/Server was powered on? I'm interested in writing a startup script that performs a specific action depending on the poweron cause.
For example:
If powered on by "wakalarm" perform task X & shutdown.
If powered on by "power button" perform task Y.
Is there any way to determine the cause of the power on? I'm running Federa 12.

I've got a F10 machine set up as a media center (with mythtv...mythdora to be precise) and I love that it's based on fedora since I'm most familiar with it..I would like to map the power button press to a command "pkill X" since sometimes the frontend freezes and running this command kills X (I'm running ratpoison for the speed and simplicity...it just gets the job done and doesn't get in the way).Any help in mapping a single button press to "pkill X" would be greatly appreciated. I also need some help adding this command to the sudo list so the regular "mythtv" user will be able to run it...no password can be entered since the machine has no keyboard. Currently I log in via ssh to get this done but it would be nice to not have to boot up a laptop just to do this.
