[SOLVED] ArchLinux does not boot if AC adapter is plugged in.

Well, actually it does not boot when AC adapter is unplugged too! When I boot ArchLinux it stops working (i.e. the screen becomes completely black without the chance to recover it) just after it says: "Waiting for UDev uevents to be processed".
The only workaround I found is to plug in the AC adapter before turning the computer on and unplug it exactly after it started booting the kernel. Otherwise it does not complete the boot process (as I said, it stops at: "Waiting for UDev uevents to be processed").
More, on KDE startup I always see a message concerning Power Management, but it is too fast and I cannot read it. If I go to System Settings > Power Management I see this notice: "Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it inside `Startup and Shutdown`". Do I have to add `powerdevil` to `Startup and Shutdown` as pre-kde startup service?
As for my configuration I have this modules in my rc.conf:
MODULES=(ac battery button acpi-cpufreq cpufreq_ondemand acpi)
The last one was acpid, but at startup it said it could not find that module, so I changed it to acpi.
Thank you,

Ok, I tried and I got something
+ -------------------------- MODULES -----------------------------------+ Result +
| ac battery button acpi-cpufreq cpufreq_ondemand acpi | FAIL |
| battery button acpi-cpufreq cpufreq_ondemand acpi | SUCCEED |
| ac button acpi-cpufreq cpufreq_ondemand acpi | SUCCEED |
| battery | SUCCEED |
| ac | SUCCEED |
| ac battery | FAIL |
+--------------------------------------------------------------------------------+-------------------+
As you can see, it fails booting only when ac and battery are loaded together.
EDIT: With lsmod I can see nobody uses either ac or battery, so can I remove them from MODULES? This would solve the problem.
Mod Edit: I added code tags -- that output was just too ugly I took them back out, they did not help

[SOLVED] Archlinux does not boot any more after update

Hi all,
yesterday I decided to update my Archlinux system again after postponing the updates for some weeks.
In general I update anything except kernel stuff, but this did lead to some dependency problems recently,
so I decided to make a full upgrade now via pacman.
After restarting the system, the kernel refused to boot. It told me, that it couldn't find my root partition /dev/sdc1 and left
me in an almost useless recovery shell. The error was:
ERROR: Unable to determine major/minor number of root device /dev/sdc1
Has anyone an idea, what might have happened? I had to install Ubuntu into a free partition to post this
topic. The disks and partitions are okay, I managed to "boot" using the old kernel, but of course the system
remained useless in that case due to wrong kernel module versions.
Thanks in advance for any hint, how to proceed.
Cheers, Zmann

Hi all,
thanks for the quick replies and sorry for the delay (children prioritized :-)
Yes, I'm using an older SATA controller (more or less 6 years), so the problem might be related to what you posted.
I was not able to boot the old fallback kernel, same error message. The fallback kernel simply uses a different initrd
file, perhaps I should think about a more sophisticated approach.
Nevertheless I already checked the file /etc/mkinitcpio.conf and it did not contain a hook called autodetect. So maybe
the mkinitcpio won't help anyway? Should I prefer using the suggested LTS kernel instead? I assume, this is done by booting
using an archlinux CD, then chroot and using pacman? Maybe it's sufficient to chroot from the currently running ubuntu instead?
Or will the booted kernel have any influence to mkinitcpio or the like?
Cheers, Zmann

Satellite 1800-814 does not start if AC adapter is plugged in

Hello,
I've got a problem with my 3 year old 1800-814.
It all began with sudden Windows crashes. Sometimes it ran smooth, sometimes it just hung up. So I decided to reinstall the notebook. My Problem is when it is plugged into pressing the power on button does not start the laptop. Just the green light is on nothing else happens. Sometimes it starts after a wait of 3 or 5 secs. On battery it starts every time. What can I do? Defect hardware or just dust somewhere?
Thanks,
Jens Grieger

Hi,
If you have a voltage tester test the AC adapter and see if it has the right current voltage, which is written on the adapter. If it does, plug the adapter into the portable and move it around, see if the light turns on and off while you are moving the ac plug(near where it plugs in to the computer, to see if it is a loose ac harness inside the computer). Does the computer randomly turn off if you have the battery removed? Or do you notice that it suddenly switches to battery power and back to AC adapter while the adapter is plugged in? Could be the adapter. Check that first. If that is good, then check the adapter plug(located on the back of the computer, where the adapter plugs in) to see if it is loose. If you find that it is loose, you can take it to an Authorised Service Provider and have them fix it. I hope this helps.

[solved] ArchLinux does not detect my usbstick

Hi,
I just installed ArchLinux a few days ago. Today I wanted to plugin my usbstick. I expected an icon to show up on the Gnome desktop. But nothing happened. Gnome-device-manager doesn't show anything. And dmesg also doens't mention anything about a usbstick plugged in. It's like the system doen's detect it.
Any idea why this is?

Dv 6809wm laptop. Computer still does not boot up when battery out and ac adapter plugged in?

dv 6809wm laptop. Computer still does not boot up when battery out and ac adapter plugged in?
It lights up initially for a split second when I push power button, but does not continue to boot up. When ac adaptor is put in it glows blue like it is supposed to. Any suggestions?

i'm going to try to see if a different ac adaptor will work hopefully that solves the issue.

Hyper-v Client in Win10 Enterprise Technical Preview does not boot to PXE via Leagacy Network Adapter after OS is installed using gen 1 BIOS

Using Hyper-v within Windows 10 Enterprise Technical Preview to boot a Win 7 Legacy BIOS (Generation 1) Operating system client does not boot to PXE legacy network adapter after operating system has been installed within the Virtual Client.
Hyper-v Client will boot to PXE Legacy Network Adapter only when no other boot device is available and no OS is installed.
Hyper-V settings seem to ignore BIOS - Startup order within Hyper-V Client Settings and will always boot to VHD before Legacy Network Adapter even if Legacy Network adapter is first in the startup list.
IF VHD is deleted and a new VHD added to the Client then will boot to PXE using Legacy Network Adapter. Again once OS is installed then will not boot to PXE Legacy Network Adapater.
Gen 2 BIOS/UEFI works as expected and boots to PXE network everytime.

Thank you for the information.

X102e - Hard drive does not boot into Windows

Hi, I was trying to reinstall Windows on my X120e.
I tried clean install with Windows 7 Professional, but the hard drive does not boot into the Windows once it has done the first phase of the install(you know, the copying part)
After the restart done by Windows, it goes as far as "Starting Windows" but does not actually boot into the Windows.
When I try to install Windows with another HDD, the device works well, but I can't swap the HDD because it is not 7.5mm think HDD.
Is there any possibility the HDD will work trough any software-level process? The HDD works fine as external HDD when tested with external HDD adapter, and installs well. only problem is that it fails to boot

Thank you for reply.
This is not exactly the issue. I was talking about the HDD originally installed in the PC.
The PC successfully recognizes the external disk I used to install the Windows, but the problem was that I did not boot into the "First boot" screen, which basically works on the already installed data.
As of now I have installed an SSD and is working fine. strange part is that HDD works just fine when I use it as an external HDD via adapter. Strange huh?

Toshiba satellite c55t-A5123 . Does not boot any devices.

I have accidentally formated the pre-installed OS in my laptop. Now I try to reinstall it again with win8 installation disk but it does not boot the DVD . i tried to make a bootable USB too but same thing happened. Anyone here can help my problem?
Is there any way to solve it.. Please I really need your help . Thanks in advance :-)

Best to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media. All the drivers and utilities are properly installed.
If you failed to create recovery media, obtain it from Toshiba. Scroll down to Get Recovery Media here
See the instructions in the section Restoring from recovery media, which begins on p. 56 of the User's Guide.

T60 does not boot with Intel T7600G CPU

I replaced my Intel Core Duo T2400 with Intel Core 2 Duo T7600G CPU in ThinkPad T60(1951-CTO) laptop. However, laptop does not boot with Intel Core 2 Duo T7600G CPU. It doesn't even complete the POST: https://db.tt/8UL8FlE0 As seen in the video, I plugged in the power adapter at 0:02 and pressed the power button at 0:06. One can hear a little click made by optical device. If I press the power button again at 0:16, this click does not happen. BIOS version is 2.27. I have reset the BIOS settings by disconnecting the CMOS battery, but this didn't help. Once I replace the T7600G with my old T2400 then I'm able to boot the laptop.
Any ideas what might cause such behavior? Shouldn't there be beep codes in case of CPU issues? What else to try?

Since you came from a T2400, does your T60 even have a Rev. 3 motherboard? If it does not, then no Core 2 Duo will work, only Core Duo's.
I don't claim to be the top authority on T60 motherboards, but I believe any will use a Core 2 T7600, 7400, 7200 if the firmware is updated.
My own experience mirrors what TuuS has stated. I have yet to see a T60/p from any walk of life with a recent BIOS that will bark at a proper Core 2 Duo CPU.

M macbookpro does not boot

macbookpro does not boot

Is it plugged in?
Does the cable show any sign of fraying?
Is there power coming through the outlet that powers something else?
Have you tried holding down the power button a few second and then letting go?
Does it have an externally removable battery? If it does, does removing the battery solve the issue?

Satellite Pro A100-080 does not boot - stays dark after 3 beeps

Hello,
after one week off, the Toshiba Satellite Pro A100-080 (PSAASE-00G004GR, 4 GB RAM) of my children does not boot anymore.
When powering on the system, it *beeps 3 times* (one longer, two short beeps), then the HDisk light shortly blinks "blue" and then nothing more happens. A/C, Power and Batterie LEDs are "blue", which seem to be the OK state.
No other useful help, as the display stays dark.
We had upgraded to 4 GB MEM (Kingston) one year ago and I already tried the former used 1 GB (included when purchased) or the 2 x 1 GB replacement from December 2007, but same status with those modules. So it is not
a defect memory.
I hope it is not the mainboard, probably only the included NVIDIA GeForce Go 7600 graphics adapter?
Does anyone have an idea, what might be the issue?
Thx for a short help.

Hello
Generally speaking this kind of beep codes are hardware related or with other words hardware is malfunctioning. So I think its a hardware problem and an ASP should check your notebook to identify the reason of this.
On the Toshiba website you will find a list of ASPs:

New MBP i5 does not boot after hard disk swap

Hi there,
I received my new i5 MBP today. After booting it once with the installed HDD to check if it's ok, I exchanged the hard disk for the one in my Late 2008 Macbook Pro. After doing this, my Late 2008 Macbook Pro boots fine with the (new) hard disk from the new i5 MBP, but the i5 MBP does not boot with my old hard disk.
To give you some details:
- I have installed 10.6.3 on the (old) hard disk that's not booting.
- The i5 MBP boots fine from the installation DVD
- Disk utility finds and can read my hard disk, no errors
- PRAM NVRAM reset did not help
- when booting in safe mode, I can see the system stop booting after or while loading Extensions.mkext
My guess is, it tries to boot and load the wrong Extensions for the new system (CPU? GPU?). I have no idea how to fix this.
Any help would be greatly appreciated!

Focx,
Welcome to Apple Discussions.
Inserting the drive from an earlier model MBP will probably not work. The version of the system you have on that HD is designed for earlier hardware so when you put in in your new machine it's going to be recognized. What I'd recommend is re-installing the disk that came with the new machine and of course putting the 2008's disk back in the old machine. Then use Migration Assistant on the new machine and migrate your data from the old machine into the new machine.
This will provide a much more stable system and should work just fine.
Regards,
Roger

Satellite L745D-S4214 Does not boot; HDD recovery partition not working

I tried to apply the recent windows 7 updates and my laptop no longer boots. I tried to press F12 and select the HDD Recovery partition, but it does not boot regardless. There is a message that it does not communicate to a specific device. I believe the address called out was 0xc0000e9, but I am going by memory. I never created a recovery CD because I thought I was covered by the HDD partitions. This was purchased on 10/26/2012, so it should still be under warranty.
PLEASE HELP!

Hi I'm going to assume that your recovery works like mine and that the recovery partition is still good and not corrupted.
Shut down your PC. Press F12 and select HDD recovery. Click enter. This should start the recovery from the hidden recovery partition.
PS I would advise you to make the recovery discs or USB recovery Try this first.
Perform a power cycle
Even when your laptop is off and unplugged, residual power can still be held in some components. While this is normal, clearing it can help with boot problems. Perform these steps to complete what’s called a power cycle.
Ensure the laptop is turned off.
Unplug the laptop's AC power cable.
Remove the battery (if the model has a removable battery).
Unplug all wires or peripherals. This includes CDs, DVDs, USB sticks, mice, printers, and any other accessories.
Hold down the power button for thirty seconds.
Reattach the battery.
Connect the AC adaptor to the power socket that was confirmed to be working in the first step.
Connect the other end of the AC adaptor to your computer.
Try starting the computer.
If your laptop starts normally now, you're done!

Satellite M30-107 does not boot correctly after Recovery disk usage

Hi
I've recently got hold of a second hand toshiba Satellite M30-107 laptop, and decided to freshen it up.
I used the toshiba recovery disk, but after doing so the laptop no longer loads windows.
When turned on it shows the Toshiba start up disk for about a second then goes to a blank screen and freezes.
When turned off and on again a screen comes up reporting an error in shutting down and gives the options to start in safe mode etc. but choosing any of the options causes the machine to freeze.
Any help or advice would be much appreciated.
Thanks
jt

Hi
Sounds a little bit like the notebook does not boot due to the Windows software issue
Did you recover the M30 with the original Toshiba recovery CD which was supplied with this M30 unit?
Maybe Im wrong but for me it looks like a wrong recovery CD was used and an image with non compatible drivers was installed
You could try to install the OS from original Microsoft Win XP CD and could check if it would be possible to get the notebook ruining using clean OS.
In such case we ( you and me ;) ) could find out if this issue could be related to the software or hardware.
Bye
