System hangs at POST after reboot

I have a Dell L400 laptop (p3 700mhz 256mb 20gb hd) and have sucessfully installed arch along with xfce and a few other programs. Everytime I reboot via "reboot" cmd or through xfce, the system unmounts everything and reboots but hangs at the POST screen. I cant get into bios or the boot option menu either. I also have a stripped down windows xp installed (before arch) and i can reboot from there. any ideas on whats going on?

Hi, I have exactly the OPPOSITE problem from you. Windows won't do a warm restart - hangs after the POST. Arch WILL do a warm restart. I still haven't figured it out. I am assuming that Windows is messing up something in the hardware that mucks up the restart and Arch isn't. Since you and I have different hardware for sure, you are likely experiencing the same sort of problem, but from a different source!
In my case, a simple power cycle resolves the problem and Windows boots properly. However, it will only boot from a power on. It will never boot from a warm restart.

T400 system hangs at POST screen after updating BIOS 7UET82WW

I have 3 GB memory and Win-7 Ultimate 32 bit OS installed in my T400 system. Recently I had updated the latest BIOS 7UET82WW thru TVSU and ended up with a serious problem.The BIOS update itself was succesfull, but right after reboot my problems started.
1. The system hangs during startup in POST screen and sometimes boots into OS after a long wait (20-30 mins)
2. When I try to press F2 to enter the BIOS, i get a long beep for about 10 seconds and screen becomes white
3. White screen garbage disappears in few seconds and blinking cursor stays for long time (around 20 -30 mins)
In net, I have to wait for around 30 mins for the system to boot into OS everytime. If I interupt in between by pressing any key, long beep and white screen garbage appears. I am not able to enter the BIOS as well.
After logon to the OS, everything seems to be absolutely perfect. But the problem comes back after reboot or hibernate and resume the system.
Appreciate any solution or feddback from anyone.

My T500 did this as well after the update. I went into the bios and loaded all the defaults, rebooted. Went back into the bios and reset my options (discrete only, turn off some unused features) and the system is working normally and Vista is booting as quickly as it had been before the update (and actually can accomplish a reboot).

Satellite A100-TA7 hangs at POST after BIOS update

Being kind of tech swavy, i know my chances are very low in fixing this but here goes.
I decided to update the BIOS on my Toshiba Satellite A100-TA7(PSAA8C-TA702C) laptop to the latest version available (6.00).
I did this because I've heard of people have better luck in making their FN keys work in linux with the newer BIOS.
The installation finished normally(went through all the steps, wrote all 21 blocks) without any errors but after rebooting I noticed that it now hangs at the Toshiba logo screen.
The blue progress bar moves twice but then gets stuck about 1/3 of the way through.
In order to see how bad the damage was, I pressed esc at the beginning of POST and saw that it gives me the right BIOS Version (6.00).
It also tells me that "No TPM or TPM has problem", and "2039M System RAM Passed."
It then displays the message "Press <F2> to enter SETUP" (which makes the message disappear, but otherwise does nothing.
If i press f2 during the Toshiba logo screen, it replaces the message at the bottom with "Please wait" and nothing happens even after waiting an hour.
(Which makes sense because before the whole blue bar would load before going into the CMOS settings). The thing is that the BIOS doesn't really "freeze", It just gets stuck at one specific place (I know this because i can press F2 even after waiting an hour and the laptop does respond to it by displaying "Please Wait".
Anyone have any more things i could try? Thank you
PS. I tried clearing the CMOS too. (By holding the power button for like 60 seconds without any power source <--- I'm not sure if this is how you do it on this laptop so any info would be nice). And I'm also 100% sure i chose the right BIOS update and followed every single instruction.

Hello Greg
I am very happy to hear you have solved this BIOS issue but I must react because of some your statements here. I do not have timet to do some research but let us write about some facts. I use Toshiba notebooks over 10 years now and I think I can say that I am pretty experienced with all this stuff.
Toshiba sold hundred thousand laptops and I can really not imagine that this can be some common problem because, I presume, all offered stuff on download page is tested. If 0.5% cases are the same it does not mean there is general problem. What you think how many people use the same BIOS update as you? I guess thousands of them.
About Linux support I can say the same as Eldorado. Sorry but I am afraid you do not understand what the support is. Just some facts:
Toshiba does not offer drivers for Linux OS
Toshiba does not offer tools and utilities for Linux
Toshiba does not offer BIOS for Linux
Toshiba does not test anything relevant for Linux functionality (very important for support)
With short words: there is nothing for Linux. If you can install Linux successfully and use it without problems you are very lucky guy and be happy, but there is definitely no support.
If you exchange experiences with other people it is really good and you should do this in the future but if you hear something and later something goes wrong it is your problem.
At the end I can say that this is user-to-user forum and you should be happy if someone here want to discuss about your problem and try to help. If you are not satisfied with comments or opinions it is your problem and if you want professional opinion you know very well where you can get it.
Have a nice day.

Update to 10.6.8 - system hang (mouse issue) after resume from sleep

I am on older
MacBook Pro3.1
Intel Core 2 Duo
2.6GHz
Run on 10.6.8 almost flawelessly. Shortly after upgrade to 10.6.8 system started to hang periodically after resuming from sleep. Symptoms are that it stops responding to mouse (be it touch pad or USB mouse). Keyboard seems to be ok but system doesn't seem to be fully functional. I am able to ssh from the other computer and 'shutdown -r now' after reboot system seem to be ok until next resume from sleep. What interesting though is that this problem newer manifests then I am using external monitor.

Found problem. It was due to magic mouse that I left on. I carry this mouse in the laptop bag but rarely use it. Last time I used it (around the same time I install the update) I left it on in the bag. It was apparently disconnecting/connecting on its own and by some reason sometimes was breaking touch pad and other usb mouse connected to laptop, as soon as I switched magic mouse off broblem was fixed

[Solved] UEFI. System hangs on boot after successfully activating swap

Alright.
Unnecessary Background:
I've been using Arch for years. I just bought a stupidly good computer with a bunch of specs that I don't think are relevant, except for the fact that I am using an X99-pro. It has RAID support, but I am not using that currently. I bought all the parts and finished constructing it this morning (I live in Japan, so that was a while ago). Normally, I have no problems with installation; however, I wanted to do this one UEFI mode. After booting into the live disk, I checked to make sure everything was working as it should. Arch recognized my graphics card, most of my ram (one of the cards is a bit finicky for some reason), my SSD and HDD, along with the built-in WiFi (although it is an annoying broadcom one, so I need to install the driver separately later). Now, there are plenty of sources of error in here:
Problem:
I got through the arch installation and tried gummiboot. It would hang every time after successfully activating swap. I tried grub, too, but had the same problem. Because gummiboot is much less cumbersome, I switched back to that. Interestingly, systemd will sometimes recognize my drive twice before activating swap, and if I edit my fstab to ignore the swap completely, it hangs on the next step with is mounting the boot partition. I would like to point out that because I am not able to successfully boot my system, I cannot provide the exact messages for you guys, which may pose a problem.
Solutions I have tried:
1. Chrooting / mkinitcpio -p linux
2. modifying fstab / removing swap from it completely
3. fresh re-install
Sources of error:
1. Construction. Everything seems appropriate on the live usb, but maybe there is a problem in which ports I used for the SSD and HDD
2. UEFI. It could be that UEFI just doesn't like mounting multiple things and freezes up when put on the spot.
3. Legacy. It could be that this is not a problem with UEFI or my construction, but something I missed in the installation.
Additional info:
Partitioning scheme:
sda1: ~500MiB boot / EFI partition
sda2: ~4G swap
sda3: ~110G /
sdb: ~2T, untouched (for storage later)
I apologize for any typos and hope it was readable. I am super exhausted and going to take a nap. I'll check back in on this in the morning.

Please post the output of:
# gdisk -l /dev/sda
lsblk -f
And the contents of your gummiboot loader.conf and arch.conf (or whatever you've called it).
Post the output of the commands after you have mounted all your partitions and (arch-)chroot'd into your system.
You can use wgetpaste to post the outputs, as described by @ewaller here:
https://bbs.archlinux.org/viewtopic.php … 8#p1500528
Alternatively, pipe the command output to a text file and export it (using a live distribution or a USB stick).
You should remove swap from your fstab -- systemd mounts it automatically anyway.

Initramfs seems broken, system hangs at boot after gummiboot menu

Did a full system update yesterday, and when rebooting the system hanged directly after the gummiboot menu with a black screen and a rainbowlike-colored bar in a pattern that looks like pink noise covering the top 10% of the screen. It seems to be a problem when loading the initial ramdisk. I have tried rebuilding with mkikitcpio, tested downgrading the kernel and rebuilding initramfs, triple-double-checked the filenames, and even verified that it doesn't look like that when the filenames are wrong. I also tried simply reinstalling the latest kernel from a chroot, but it didn't help.
I have pinned down the problem to the initial ramdisk, but can't figure out what else to do with this. I don't really want to do a full reinstall if it's possible to avoid. The system is a lenovo thinkpad w530 and I boot arch linux in uefi mode using gummiboot.

Unfortunately, no, I still use EXT4 on my system. However, what do you mean when you say "got unmarked as the default one"? Is that something local to rEFInd, or what do you mean?
I have tried downgrading to Linux 3.7.5-1, but that did not help unfortunately. My system worked with 3.7.5-1, when I upgraded to 3.7.6-1 it stopped working, and downgrading didn't help. I'll try downgrading to a 3.6 version though.

Tap to click setting in system preferences not persisting after reboot!

Hi,
This is the 2nd time this has happened.. I shut down my system, and boot it up later, and when I go to tap, nothing happens. I go into to system prefs > trackpad, and see that my tap to click & dragging options are unchecked......
Why is it not remembering those settings?
-patrick

I also have this behavior. It seems all trackpad preferences fail to persist after reboot and logout/login. I also disable Pinch Open & Close and Rotate settings and those also revert.

System Attributes/Preferences Discarded after Reboot

I have re-installed OSX Lion, Run Repair Disk a number of times, Repaired Permissions 3 times and restarted in Safe Mode before restarting as normal and resetting my permissions as I want them. After a reboot, those permissions default to their original configuration, e.g. iTunes defaults to the directory on the system disk but I had set it to the directory on an external disk.
Help would be appreciated.

I modified an applescript sample found at http://stackoverflow.com/questions/25645075/apple-script-to-select-system-prefer ence-notifications-alert-style to achieve removing Calendars from the Notification Center (as an example) after rebooting or logging in again. I'm using Keyboard Maestro to run the script at login. Note that when Apple fixes the bug, I'll discontunue using the script as it may have unpredictable results (or exactly the opposite results). Use at your own risk, thank you. It works for me though I'm unsure if it will work on all other systems. The script follows:
tell application "System Preferences"
    activate
    set the current pane to pane id "com.apple.preference.notifications"
end tell
tell application "System Preferences"
    reveal pane id "com.apple.preference.notifications"
end tell
tell application "System Events" to tell window 1 of process "System Preferences"
    repeat with r in rows of table 1 of scroll area 1
        if name of UI element 1 of r is "Calendar" then
            set selected of r to true
            exit repeat
        end if
    end repeat
    click radio button "None" of radio group 1 of group 1
    click checkbox "Show notifications on lock screen" of group 1
    click checkbox "Show in Notification Center:" of group 1
    click checkbox "Badge app icon" of group 1
    click checkbox "Play sound for notifications" of group 1
end tell

System Hangs on X-kill, reboot, or shutdown [an fglrx problem].

I'm pretty sure this is linked with my new monitor somehow. I got a new monitor, its hooked up with the DVI cable. Whenever I try to:
exit openbox
ctrl-alt-backspace to kill x
restart (shutdown -r now)
or shutdown (shutdown - now)
my system hangs. My screen shuts off, and starts blinking the power button, and its not responding.

I've no idea whether it's possible for a new monitor to somehow cause this... are you running ATI or nVidia drivers? Is direct rendering working, do you know?
Try doing
$ sudo chown -r yourNonRootUser /path/to/yourNonRootUsersHome
and seeing whether that remedies the problem with exiting openbox.
Also, look in /var/log/ for your Xorg.#.log files (I forget whether they're in a subdirectory in there... maybe under /var/log/x11/ ). See whether the most recent log file has any warnings or errors (EE or WW in brackets) that may indicate the source of the problem.

System does not post after Bios Flash

After using Live Update to flash my Bios to the new version, the computer does not POST. The Bios Flash was successful - it rebooted and started normally. When I tried to restart it the normal way, it will not boot. The fans run when the "power on" button is pressed but nothing more. I cleared the CMOS using the jumpers but the problem was not solved. Can any one help?
Can some good Samaritan give me a step by step method to resolve this problem?

I followed the link you provided and managed to resolved it:
1) Removed one memory stick and floppy;
2) Cleared CMOS and rebooted successfully;
3) Inserted floppy and reverted to the previous BIOS;
4) Inserted the other memory stick and brought system back to full power again.
Thank you very much for your assistance. I am sure MSI is aware of the problem and will take steps to rectify it ASAP

[VIA Series] PT880 Neo-FSR hangs during POST after connecting USB device

I "successfully" built a new machine from scratch for the first time. Windows 2000 was installed and working with updates. I connected an iPod to a USB port (during the iTunes software installation) and the machine froze. After a power cycle, the machine will not successfully boot. After the fact, I discovered that the grounding wires on the USB2 connector were no longer connected. I'm not 100% sure that I plugged the iPod into the USB ports connected to USB2, but that's a good assumption.
On reboot, the screen starts normally. When the line "DEL: Setup F11: Boot Menu F12:Network Boot TAB: Logo F10: Flash Recovery" appears, the machine stops. The next line reads "Flash Recovery". The D-Bracket2 indicator lights stop at "Testing Base and Extended Memory".
I'm unable to select any of the options to enter the BIOS setup, etc. I tried clearing the CMOS data using the jumper and I now get the logo screen, but the system still hangs with the same D-Bracket2 lights.
I do not have any spare memory, so if I need to swap it out for diagnostics, I'll have to go shopping.
Is there any way to salvage this board or did I permanently fry it?

No luck on entering BIOS or getting graphic screen to clear.
To clarify, I cleared the CMOS in despiration after the system hung and I couldn't get into BIOS. I don't remember all the details from the original screen (before it was obscured by the graphic!), but I know that there was no "error message" per se. Everything appeared normal except that "Flash Recovery" appeared an additional time below the "DEL: Setup..." line. Before clearing the CMOS, I had no apparent response from any key. (DEL, F10, F11, F12, etc.)
I'm inclined to assume that I managed to actually fry something on the board, but I'm hoping to get that confirmed before buying a replacement.

[SOLVED*] system hangs at startup after grub screen

My system is hanged after the grub window. I choose Archlinux, like always, apparently starts to boot and the next screen is frozen. It says:
/dev/sda2: recovering journal
/dev/sda2: clean ....
systemd-fsck[208]: /dev/sda1: recovering transactions file
systemd-fsck[208]: /dev/sda1: clean ...
systemd-fsck[221]: /dev/sda4: recovering transactions file
systemd-fsck[221]: /dev/sda4: clean ...
And that's it. It frozes in this point. I didn't make any update since 3 days ago. Yesterday the computer runs well.
I tried to enter into Fallback mode, but I get to the same point.
Any suggestions?
Solved partially: I connected a second screen this morning. When I disconnect it, the system starts. Now I have to solve how to add a second screen because when I add it once the system is running, it hangs.

System goes read only, after reboot all is fine for a day or two

OK, so here's the problem, I got a new PC, all fanless, SSD hard and all.
Works well for a day or so, then goes read only. For example - I come back from work, type something in the terminal and I get Input/Output Error. I cannot reboot, it says Input/Output Error as well.
So I hard-reset it, it boots up, everything is fine again for a day or two.
The HDD is Corsair CSSD-F40GB2, the MB is Gigabyte H55N-USB3, proc i3 540,
The / and /home are both ext4 mounted with defaults,noatime,discard.
I tried with/without discard.
I also tried changing the SATA/power cables - same results.
I also tried enabling/disabling features in BIOS like DMA/SMART/AHCI/compatibility stuff - same results.
Here's a dmesg I managed to get (errors are near the end).
http://pastebin.com/vJfdW90z
And here's a smartctl -a /dev/sda:
http://pastebin.com/eQxASEBM
Any suggestions are welcome. Also is there some diagnostic app for Corsair SSD that I can run and check the drive?
Cheers.

Well I don't recall how freshly booted, it was the only time that the system was read-only - giving input/output error to everything but dmesg was working so I saved it all to pastebin.
The system is a PC so I never tried anything else different from poweroff/reboot (works fine).

Strange system hangs, ati graphics card issue?

So okay, I`ve bought a new laptop, installed arch (I don`t regret it), everything was fine and so on back then.
I was running 2.6.13 and ati-drivers 8.20.
No problems.
Then I have tried upgrading to 2.6.15.
I was able to boot, again, everything worked.
However after a hour or so system completely froze.
After reboot everything was fine again. For few hours.
Needless to say that I`ve downgraded to 2.6.13.
Yet again, everything was perfect.
Of course I couldn`t stay on 2.6.13 forever, so few weeks later I`ve upgraded back to 2.6.15.
This time I`ve download 8.22 ati drivers.
So far so good.
I`ve experienced freezing few times again, but it wasn`t so bad, one reboot a week, so I didn`t bother.
Now I`m on archck, using ati-fglrx-archck package (8.23.7-1).
System completely froze again, second time in two days.

Sorry, didn`t really know where to post this thread, it might be kernel/hardware issue, but might not as well.
I have no idea what causes these hangs, it`s just a guess that it`s ATI.

KT3 Ultra2 hangs during POST - Memory Detection

System specs:
KT3 Ultra2
Athlon XP 1900+
GeForce4 Ti4200
PC2700 512MB RAM non-ECC
***Nothing else connected***
The system only passes POST after clearing CMOS. When I load the default BIOS settings, the system hangs when it gets to the Memory Detection step of POST. I have tried different memory sticks and even motherboards with the same results. This seems to be a BIOS settings issue. Any Ideas???

I have tried 2. Mushkin (Samsung chips) with a heat sink. The other was oem and the chips are also Samsung. Same problem with both.
The Mushkin works fine in another system.
