Fedora Hardware :: Battery Replaced - BIOS Not Load ROM From PCI Adapter
Jan 16, 2011
I just replaced the battery on my motherboard in an older computer that I was going to load Linux on. Before I replaced the battery, I booted up the computer and my old copy of win2k loaded up fine. Now that I have replaced the battery, the BIOS will not load the ROM from my PCI ATA adapters (one SIIG ATA 133 IDE controller, and one Promise ATA 133 IDE controller) which are hooked to my hard drives that I boot from (software raid 1) and the CDROM drive in the system (along with some other hard drives for storage). I removed the adapters and stuck them in another computer to check them. They both loaded their ROM's into the BIOS of the other computer. So the cards are fine. The computer has an award BIOS. I have checked all of the settings and reset the CMOS again, but it will not load the ROMs from the PCI controllers into the BIOS on boot.

I have an HP Compaq nc4010 laptop, with Debian experimental installed on it.In the BIOS utility, I can view what they refer to as "battery information".Unfortunately, it's all horribly abbreviated, so I can only guess what the labels mean.Is there any way I can acces this same information from linux, preferably with full labels and/or descriptions?

A couple of days ago, my laptop battery starting discharging at random times. I could rectify this by either pushing the A/C cable in or rotating it slightly. Now the battery discharges unless the A/C cable is pushed in constantly. A few months ago I had a similar problem, though it was accompanied by the computer randomly shutting off. The battery had to be removed and reinserted before I could successfully power the machine back on. Purchasing a new A/C cable fixed this problem quite well. I suspect it may be the battery this time. The gnome battery monitor in LMDE is going completely nuts, announcing I have five minutes of power left and then happily informing me that I have 10 hours 42 minutes only a few moments later.

My Setup: Dell Laptop (BIOS allows boot from USB) - Vista 32 bit installed, 4 GB memory
External 500 GB HDD (iOmega) - Partitioned as follows:
NTFS: 50 GB
/boot: 1 GB
below two on one logical volume:
swap: 5 GB
/: rest ~ 440 GBI installed Oracle Enterprise Linux on the external HDD.
Did not install the Grub bootloader as I don't really want a startup boot option. The way I was planning to make it work was: When USB HDD connected and laptop powered up, it'll boot to the Oracle Linux. When the USB drive is not connected and laptop powered up, it'll boot to Vista. When I boot with the USB HDD connected, nothing happens. I get a blank screen with a blinking cursor. The USB HDD light comes on though. Is the above plan possible, or do I have to have a Boot loader installed?
If I have to have a boot loader installed, how can I just install the bootloader and not have to reinstall Linux on the HDD. The Linux drive is currently empty, so I'm open to any good suggestions to partitioning it. I want to keep a small amount of NTFS space on that drive to store some windows files and documents that I can carry around. The rest 450 GB is open for Linux. And I Plan to install Oracle Database and Apps on Linux (which takes about 350 GB of space).

I have a Samsung R510 laptop, with a short-life battery (holds up to 1.5 hours) Is there any way to make my laptop work longer by using some tweaks? Maybe it is possible to change the CPU according to the load?

I just want to tell laptop users how they can protect their hdd from heavy load cycle count (spin up/down of the hdd) when using battery.If you are not sure then just type this command several times in interval of 1-2 minutes, and you will see how much the hdd head spins down, and up: Code: sudo smartctl --all /dev/sda | grep -i load_cycle.Change /dev/sda with appropriate hdd path for your pc.

Im trying to test out Ubuntu while running Windows currently, once i got the ISO image installed into my USB device by following the steps on the Ubunto site, i rebooted my PC and tried to get into BIOS to change the setting to boot through the USB device.
but i was unable to open BIOS.
this is all i saw in the bottom right side of my screen as far as commands to open some thing before my PC would boot through my Cdrive and load Windows.

I have installed Fedora 11 and I have set it up as a web server with Apache. I have a domain name from GoDaddy that I own and I have set it to my web server. I am able to type the address into a browser on a computer outside of my network and it will pull up the web pages on the server. the problem that I am having is that after I type the URL, it gets replaced with the IP address. [URL] I know that I need a nameserver to resolve the IP address but I can not figure out how to do it. I have tried to use Bind but I can never seem to get it to work.

I use Fedora 13 (minimal installation), ISC DHCP server 4.1.1-P1. I'm running Fedora 13 too on a separate machine (minimal installation) with ISC DHCPclient 4.1.1-P1. My goal is to do some IPv6 testing. When I use the DHCP client manually (dhclient -6 -timeout 5 -d -v eth0), the client retrieves and installs a dynamically assigned IPv6 address.
Additionally, the client gets 1 DNS resolver address and 1 DNS search list. The resolver address and DNS search list always get written into /etc/resolv.conf. Perfect, exactly what I need. But when I do a "service network restart" or restart my system (which should trigger the same, as far as I understood), the DNS resolver addr and the search list get written into /etc/resolv.conf.save and the /etc/resolv.conf stays as before. How can I change this behavior? I don't need the .save file, I just want to have /etc/resolv.conf replaced by the latest DNS information.

I was using ubuntu 11.04 with a separate boot partition. Then i installed fedora 15 during which i erased(format) the /boot partition which holds the Grub2 entries for ubuntu. And its been replaced with the Grub's of Fedora. My Ubuntu installation is still intact sans the /boot folder. i tried copying the ubuntu vmlinuz and initrd into /boot (now belonging to fedora) and booted from grub - it throws me into initramfs , from which i dont know how to get into the lovely GUI of ubuntu .
[Code].....
where /sda1 is boot ; /sda7 is home ; /dev/sda10 having the [once] ubuntu installed files without /boot folder ; /dev/sda3 my fedora installation from where am typing this. Can i make a dual boot of ubuntu and fedora now without the need of reinstalling ubuntu again

I have old app that by default is looking for /dev/dsp as an audio device. The source is configured as such and I want to change that so sound will work on current versions of Fedora.
What is the equivalent of /dev/dsp in F15 ?
I think /dev/dsp was the default generic sound device .. ?

Above adapter can be installed on v10.2 and 11.3 using ndiswrapper:-
1. Copy the 3 driver files from Windows:- like netwpn111.inf, WPN111.sys & ar5523.bin.
(Be carfeul about the exact names, because they have changed over time).
2. sudo ndiswrapper -i netwpn111.inf
3. sudo ndiswrapper -m
4. sudo modprobe ndiswrapper (the adapter should light up at this point and networks will be detected shortly after - see network manager). (Be careful of paths here - e.g. I had to use /sbin/modprobe - so 'whereis' may be necessary to find these commands).
2nd When I reboot, I need to run the modprobe command again. How do I make the module load automatically on boot? Also (and this is minor), can I bypass the KWallet, keyring thing? it seems silly to enter a password for the keyring and then click another password dialog, when I can just as easily enter the password for the network itself.

getting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactions and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.
Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery Maintenance utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.
I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.

Just installed 9.10 followed by a 10.04 upgrade (wouldn't work as a 10.04 clean install). The install and upgrade all seemed to go well.
But now when booting I get a message saying "checking battery state" and then it boots no further. This is a laptop without a battery installed, running permanently from the mains through the charger.
How can I disable this check so that the laptop will still boot without a battery fitted?

I had Fedora 7 and Windows Vista dual booting on my computer. I just installed Fedora 10. When the live CD asked me where to install it, I chose "Remove all Linux Partitions and create default layout" The installation went perfectly, but now when reboot my computer, it boots directly into Fedora; GRUB does not load to ask me which OS I want to load. I know I did not overwrite Vista because I can still view my Vista files through Fedora. Here is my grub.conf file:

What do I need to do to make GRUB load again upon booting?

I have a 3 year old laptop with the original battery and its drained pretty bad. The "Battery may be broken" popup was driving me insane and this is how you disable it, in case you are in the same situation as me. Open terminal
Code:
gconf-editor
Drill down to...
apps --> gnome-power-manager --> notify
uncheck the low_capacity checkbox. This should disable the popup for you if your battery has little life left in it. Now, if any knows how to disable the Avahi popup, let me know.

I've got a font issue on my system: The normal arial is missing from my system and all software substitutes it with arial-black. It's a system wide problem:Firefox, konqueror and chrome all render Arial texts as Arial-blackOpenOffice and GIMP only display "arial black" in font selection, not arialInkscape displays bot arial and "arial black", but they're the same font.I tried reinstalling liberation-sans-fonts package and even rebooted, but the problem remains. I checked my fontconfig configuration, but nothing seems to be wrong.I believe the problem first occured after I uninstalled VirtualBox (proprietary edition). But I'm not sure.

I am using Fedora 12. Prior to this I was using Ubuntu 9.10. In Fedora 12, I am facing a problem with battery power. Sometimes when it is fully charged I remove the power cord, battery power comes down to 40%-41%. It never happened with Ubuntu, which gave quite a good battery performance. My question is when it is showing Laptop Battery 100% i.e. fully charged, if I remove the cord why it comes down to 40%-41% (and always in this range).

So I just installed F15 and I really like it. I had to upgradde to kernel version 2.6.39.1 to get my wireless from disconnecting -- aparentlyey it is a bug in kernels 2.6.38.x .Now my problem, and it was also a problem with kernel 2.6.38.x, is that my battery life on my netbook (gateway LT2320, atom n450 @1.6, gma 3150, 1gb ram, 1024x600) is cut by half. I used to get 7-8 hours of battery life, with Crunchbang, Ubuntu, etc., but now i get 4.5 hours.I have read that this is a problem with the current kernels available after 2.6.37.x.
My question is have they found a fix? Are we going to have to wait for 2.6.31? How much longer until that kernel is in the fedora repositories?

I reinstalled fedora the other day, and it's been working just fine, apart from the internet. It shows that I have a full connection with the wireless network, but it's really difficult to actually load a page. 80% of the time it just fails and shows "Page Load Error". It's really frustrating because it is connected to the internet. In fact, the icon in the address bar even loads from the site I try to access, but websites just will not load.
I've tested my wireless internet with another laptop which is running vista, and it works perfectly on that. Also, I'm running Fedora 10 on an Acer Extensa laptop.

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code:
title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
