Hardware :: PC Wont Power-on - Power-light Blinking?
Oct 30, 2010
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?

To protect my eyes I always lower the monitor's brightness to its lowest. In some of the computers/displays I can get the desired low brightness in some others I cannot. For example in my WinXP ThinkPad R51 laptop I can make the brightness extremely low while in Ubuntu 9.04 ThinkPad R41 laptop and Apple Mac mini/23" Cinema Display I cannot get the desired lowness easily.
But in my Ubuntu 9.04 ThinkPad laptop, just as the energy saving routine has started to dim the brightness of LCD, an idea has come up. The energy saver routine was apparently lowering the fluorescent light's power, I'm sure of it. So I wonder now if there's a way to control and set that by myself? I'd like to set the fluorescent light's power to a much lower level.

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.

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.

Kubuntu 10.04 64-bit
Gateway laptop
I popped in a scratched up CD of my wife's friend's music. It would not play or copy, had to just try anyway. So now the optical drive tray will not open, and the light is blinking. I have restarted the machine. Could this be my OS or other software error?

i have been using it since a friend suggested to use it a month or so ago. I have knowledge of computers so I am not ignorant of everything (I say this for the linux pros in case this is a simple solution, and I have checked many forums before actually posting this question with no luck) and have tried several options. My laptop freezes at random times with the caps lock light blinking which seems a little strange. the only correlation I can make to this problem is that every time I use only wifi without the ethernet cable plugged in it will freeze. I have read a few forums that say it could be a bug in the wireless card drivers and some suggest it could also be graphic card drivers but it seems to only happen when wifi is enabled.I am using an ASUS G73 series with an ATI Mobility Radeon HD 5870 1GB GDDR5 graphics card, 8GB DDR3-1066 RAM, Atheros AR9285 802.11n Wireless LAN adapter, and an Intel Core i7-720QM processor (1.6GHz/2.8GHz Turbo Mode, 6MB L3 cache). I am also running Ubuntu 10.10 off of a 320 GB seagate Momentus and windows 7 off the stock 500 GB Seagate Momentus.

I had a problem with the new network manager a week ago and got it solved with help from the forum so now I'm back again. I have a dual boot with Windows 7 (I have to use it when serving my corporate masters) so I wasn't in my Fedora partition much this week.
I just noticed this and I'm positive it wasn't doing it before my network manager problem but I'm not sure when it started or if they're related.
I'm running F15. The machine is an HP Elitebook 8440p and has a wifi light that is also a touch button to turn the wireless on/off. Whenever there is activity on the network now it blinks between orange and blue. I know that isn't really a big deal but it's really annoying and is driving me completely nuts!! The normal behavior is orange when it's off, solid blue when it's on (or connected) and blinks orange/blue just while it's connecting. During network activity it's always been just solid blue and that's what I want.
I found a script that some Ubuntu users said fixed the same problem but when I tried to copy it the directory they said to put it in "/etc/network/ifup.d" doesn't exist. I'm assuming that's a distro difference between Ubuntu and Fedora?
Has anyone else seen this? Any ideas how to fix it?

I am new to Ubuntu and am confused on how to fix my flashing wireless light issue. After browsing Google people are recommending that I make a script and put it into a folder, but when I try to put the file in there I get an error of "Error moving file: Permission denied".
Code in script...

Not doubt this sounds alarmist, and perhaps it is... anyway, earlier tonight my mum complained that her home network connection wasn't working. After complaining about Windows and running a virus scan, I returned to my laptop, only to find my Ubuntu 10.04 was having the same problem. Then I noticed the wireless connection light (next to send and receive, which always blinks anyway) was constantly flashing, as if transmitting data, even though neither of us was connected, of course. I turned the router off and on again a few minutes later. Initially the light was still blinking abnormally, but I could now access the internet, as could mum, so I ignored it.
Later on, while the virus scan on mum's computer was running, Windows notified her she was running out of hard drive space - normally about 30GB of the 51GB HD is used on her laptop, but suddenly 50GB had been used. I also noticed my 275GB Ubuntu partition had 235GB free (although total size of files on disk was 128TB - a bug perhaps?), i.e. 40GB used, which seems pretty large for a rather fresh install and a handful of documents!Currently, everything's normal where my router's concerned (no blinking lights except for my browsing), and my Lucid partition is still showing 235GB free (strangely, mum's laptop now shows 46GB used instead of 50GB). So, what do we make of all this? Were our computers hacked for storage space?

I installed Linux yesterday alongside windows vista. Everything went very smooth. I restarted the computer multiple times without issue, and the menu would pop up asking me which os to load. Everything was good. But today I attempted to boot up my computer and nothing happens. The screen just stay black. The lights come on on the laptop, but nothing else. Either I try to boot it and it goes on then off quickly, or it just sits there, still on, with a black screen. I don't know if this is related, but when I was messing around with ubuntu yesterday after I installed it, it would randomly freeze and my caps lock light kept blinking on and off. I was forced to restart when this happened and then everything would be ok.

I have a Compaq Presario CQ60 laptop and have one of those wireless light indicators. For me the light glows orange when the wireless is OFF and blue when the wireless is ON. In Ubuntu 9.10 (Karmic) the light was always orange, even if the Wireless was on, but my wireless worked right out of the box so I was grateful for that, but since upgrading to Ubuntu 10.04 (Lucid) I've noticed that my wireless light alternates between orange and blue frequently and sometimes flashes madly when wireless activity is occurring.
I was wondering if there is a fix for this as it can get quite annoying, the light sometimes stays blue for a while but will ultimately keep going back to orange and vice-versa, my friend who also has a Compaq Presario CQ61 (Revised model of mine) has his wireless light constantly blinking orange and blue no matter what.The wireless itself works fine, I can connect to any wireless connection and use it without having to install anything else, so it does work out of the box, which again, I'm grateful for.The wireless adapter is a Atheros AR5001 Wireless network adapter. Do I need to install additional packages or drivers to get the wireless adapter to work properly?

I need to know the necessity of swap partition in Ubuntu.. I have recently bought a new HD and installed Ubuntu(with NO swap,only Ubuntu on a single partition) on it and am facing frequent,random hanging issues with it.. Earlier,my old HD used an swap partition along with main partition and i never faced hanging issues at that time..
Actually, when in hanging mode,the cpu light keeps blinking continuously and the mouse movement is very slow,the screen also becomes dim.After sometime,it comes out of hanging mode and mouse movement becomes normal.Sometimes,even after waiting for 15-20 minutes,it does not come out of hanging mode and the system has to be restarted.(this is what forced me to look for a possible solution to this)

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 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'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.
