Thinkpad L520 won't boot without nox2apic kernel parameter

I can't boot using any of the stock arch kernels since 3.2.0 unless I disable x2apic. There's a bug report at https://bugzilla.kernel.org/show_bug.cgi?id=43054, apparently it's affecting other thinkpads as well.
If anyone else is having problems, try adding nox2apic to your kernel command line or compiling a kernel without CONFIG_X86_X2APIC. And be aware that installing arch using the net install iso will require using this parameter or ignoring the linux package when downloading/installing packages.
Booting without disabling x2apic was completely locking up @ the line:
"ACPI: EC: Look up EC in DSDT"

Interesting. No issues here with a T410.

Windows 8.1 Pro won't boot without USB Stick

Please HELP! I bought a Thinkpad e555 without OS, created installation media for Windows 8.1 in a 64Gb USB stick. When the installation was finalized, I followed the instruction of removing the stick after restarting. After powered on, black screen for hours. Put the usb stick back and Windows booted, finalized the installations and configurations, and started normally. So I started with all of the drivers downloads and installation. So I removed the usb thinking that everthing was ok. But when a restarted it, it wouldn't boot until I restarted it with the usb plugged. Complained with the retailer and sent me a new one. Now I'm trying the installation all over again using a 16Gb USB stick. The same, the OS won't boot without having plugged the USB that I used for installation. What am I doing wrong?

I have this problem on E455. Both in 8.1 Pro.It was after a driver update, but not sure which one.It doesn't what USB device is attached, just so long as there is one.

OS Mavericks won't boot without using safe mode

My macbook pro won't boot up when its not in safe mode. It gets to the apple screen and then freezes but I can move the mouse around. Safari also won't open even when it is booted in safe mode.

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the suggestion of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only run the test in safe mode, proceed anyway.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the script twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, just run the script as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it.

Intel D2700DC + Arch won't boot without display

I've faced really wierd (to me) problem running Arch as mini webserver on the Intel D2700DC mini-ITX board with Atom D2700 integrated and NM10 Express chipset.
I successfully installed the system, configured network and started sshd to continue setting up other services remotely via ssh console. Then I disconnected the keyboard and display from the case and put it under the table. After that I was quiet surprised that the system was not starting up anymore.
After some investigation I've found that the system is not booting if no display is attached to the DVI port of the motherboard. If I start the system with display disconnected, I can hear one beep that notifies about successful BIOS POST, HDD led blinks 2-3 times, and then just nothing happens. System isn't booting up. If I attach the display right after that - nothing is seen on the screen, and display is immediately falling into sleep mode. Keyboard is still active though, and if I press ctrl+alt+del - the system is restarting, and, if display was just connected, it boots ok then. Also it boots fine from the cold state if the display was attached to the DVI port at the time of powering on.
As I can assume from the timings and HDD led blinking, the boot process stops right after GRUB is loaded. There's nothing in system log, cause it seems that boot hangs just before the kernel is loaded by GRUB. I'm really stuck and don't know how to work around this situation, because if the display was disconnected when system was powered on - then there's no way to see anything on the screen until next reboot, and if the display was connected - then the system boots OK.
One more thing to notice:
There was an old CentOS installation on the HDD, to which I installed Arch Linux. I've tried to boot it once or twice before installing Arch, and, as I could remember, it could boot up without display connected, on the very same hardware. So I suppose it's definitely something in Arch that is preventing the system to boot without the display.
I guess that when no display is connected at boot time, NM10 chipset completely disables onboard video, and because of this we can't see anything on the display until the system is restarted. But this somehow affects Arch, so it can't boot without any video hardware present.

I'm afraid there's no such option, but it looks like arch isn't booting just because no graphics card is detected in the system when display it disabled during powering up.
There is a couple of similar topics about some other linux distros can't boot without video card inserted ([1], [2]) with some recommendations on what to do in such a case.
I've followed them - including enabling serial console in /etc/inittab, setting nomodeset in kernel line in grub's menu.lst, checking for enabled splash-screens... but that didn't help.
Does anyone know what options should be tuned in order to boot Arch without any active graphics card present in the system hardware?

Toshiba CB30 Chromebook won't boot a custom kernel.

I've had Arch running on my Chromebook for a while now, but I haven't been able to figure this out.
It runs fine with the standard kernel. The problem is, when I install any custom kernel it won't boot. I've tried both linux-ck and linux-chromebook and I get the same error, so it's not a problem with the kernel.
This is the error I get
I've tried re-making and re-making the GRUB config, so I don't think it's a GRUB problem.
Any ideas?

Two ways of reaching the data if your hard drive is still alive, Sue.
(1) Download a free CD that boots to another operating systems or to a preinstall environment and copy important files to external media. A popular bootable disc is Ubuntu. There's also KNOPPIX, Bart's, UBCD4Win, SystemRescueCd, and others.
(2) Remove the hard drive, mount it in an external enclosure, and access it from another computer. To remove the hard drive, see the first two steps here.

Factory fresh Thinkpad T440 won't boot into preinstalled Win8

As the title already tells,
my company orderd new Thinkpads with preinstalled Win 8.
So I packed one out and pressed the power on/off button but the Thinkpad won't boot into Win8. Right now it hangs in the screen where I can choose from which option I'd like to boot (network, SSD etc.)
So I decided to take another one but it has the same problem.
I have no clue what I can do about this problem.
Has anyone a suggestion for me what I can do now ?

Hi Mjschuster,
Welcome to Lenovo Community!
Check if the HDD is detecting in the BIOS.
If yes, then perform “System Restore” to reinstall the Operating System.
If it is not showing in BIOS, try reseating the drive.
Best regards,
Hemanth Kumar

Won't boot without video card

Hi,
I have a PT880 Neo-LSR and am trying to run a unix OS. This is the first time I've used a MSI board, but I've used many other boards without graphics cards since these are being used as servers.
The problem is that the OS won't boot up unless I throw a pci video card or a agp video card on the board.
Is there any way around this? I've searched in the bios but nothing looks like the culprit. Is there a jumper? Or is this a limitation of the board?
Thanks,
Bob C

I have never had a Server Board but why would you want to boot up a OS without a vidieo card...??? You should be able to post up to the point where the Beeps will let you know that no video card is present.. if a speaker is hooked up.. How you going to see what you are doing in the Bios.??? I must be Tired ....

Windows 7 won't boot without optical drive (SSD, Dual HD)

I recently purchased an SSD and an optical drive HD caddy so I could use two HDs on my macbook pro. I installed the SSD in the normal HD slot in order to install Windows via optical drive. When I move my SSD over to the optical drive slot, Windows hangs on a black screen before the Windows logo and never boots. I tried moving the SSD back to the main HD slot but without the optical drive installed, the same symptoms occur - no boot. This leads me to believe that Windows will not boot without the optical drive (which was present during installation).
Perhaps this is a problem with primary/slave drive settings? I learned today that the intel chipsets in macbooks do not have BIOS for Windows and do not allow you to access the EFI. Not sure if that would help anyways.
Has anyone experienced this and/or have a solution?

I am suffering the same issue. Macbook pro 15 inch late 2009 with 8gig ram. I have a 256gb ssd newly installed, a dead superdrive (thanks a bunch for the drop in build quality without the drop in price apple) and an optibay caddy which i intend on having my 500gb 7200rpm previous HDD installed in. I had the normal annoying issues trying to get bootcamp working with an external optical drive. I then had the bright idea of taking my external optical drive case apart and discovered its a sata drive with a sata to usb convertor attached. Got bootcamp/win7 installed fine using the superdrives sata connector with the optical drive (essentially having a temporary internal optical drive again).
OSX and windows function fine as long as the optical drive stays connected. There does not need to be a disc in the drive, i thought windows might be getting boot info from the win disc. Osx boots fine if its just the ssd. Windows hangs with a white screen right at the beginning. Also doesnt boot using boot menu via alt key. Nor using the reEFIt boot menu (installed later now deleted).
Disk utility says it cannot repair the windows partition and says to back up the data and reformat the drive. This also happens if i use a normal sata drive. I am attempting a few more ideas but at this rate i will be virtual machining windows instead. Far from ideal but seeing as my windows pc is now officially no more and there are two pc only programs i need to use for university i dont have much choice i NEED windows. Anyone got a bright idea that may help?

2014 DFR X1 Carbon Won't Boot without AC Cord

‎11-30-2014 04:36 PM
Apparently have to start a new topic...so here goes...
Brand new machine.
can boot with AC cord attached (after 3 blinks of the power switch and the Red LED on laptop lid). but without, the laptop does not boot.
have installed the 1.18 bios and checked for any hardward drivers errors
please help.

I had this problem too and our engineer changed the motherboard which seems to have worked for some people but not for me. The engineer then noticed that the "intrusion switch" which is on a small 3cm sq board was a bit floppy.
He changed it for another board that had a switch that felt more positive and closed up the machine. After attaching the power for the initial boot up it has now worked on every boot up without any AC cord attached. Hope this helps.

My ThinkPad T400 won't boot!

I honestly have no clue what could have caused this!
I turned it on this morning & it was stuck on the booting screen. It read "ThinkPad" in large letters followed by "To interrupt normal start up, press the blue ThinkVantage button." I waited for about a half hour for it to boot & it never did. I of course pressed the ThinkVantage button & to my dismay...nothing happened. Afterwards, I unplugged it & removed the battery pack. I then plugged it back in & attempted to start it up again. Once again, nothing. I unplugged it again & attached the battery pack. At that point I tried starting it up again and N O T H I N G!
What do I do?!
Solved!
Go to Solution.

have a look at your usb ports, there could be some sort of pins touching, as the result of damaged usb pins.

P55-CD53 Won't Boot Without CPU

I know this is probably a dumb question, but I just got all my parts in except my GPU and CPU. I plugged everything in and bumped the power button on the motherboard while hiding some cables. It started up, a few lights came on, and it instantly shut down. It went into a loop of flashing on and off every 3 seconds until I shut the power supply off manually (switch in the back). Did I mess anything up? More importantly, did I find out that my board is faulty? Or is it just doing this because the CPU isn't installed?
Currently, I have:
RAIDMAX RX-630SS PSU
P-55 CD43 MSI motherboard
GEIL DDR3 1066 2GB (x2) RAM
What just happened?

Quote from: cpljwlusmc on 03-January-11, 10:03:19
Just to clarify, I wasn't trying to boot my computer without a CPU. That makes no sense . I was concerned as to any damage as to what may have happened (if any) by accidentally starting up my motherboard. As I stated before, I hit the motherboard's power button accidentally while moving around some extra cables (i don't have a fully modular PSU). Also, I have heard a couple incidences where the MSI P55-CD53 will not start up at all, and will light up for a second and then shut down. I was concerned because I thought I may be having the same problem. But that will be determined as soon as I get my Core i5-760 in it. But my main concern was if I had inflicted any damage to my motherboard in any way. It's not something I've ever done before (I'm usually more careful than this lol), so I wasn't sure. I'm not COMPLETELY dumb, lol
Refrain from even taking the side panel off whilst it's powered. Some static from you and you could damage something. It's not worth the risk.
May I ask why the power cable was even plugged in, never mind turned on?

ThinkPad T400 won't boot

My ThinkPad T400 was in sleep mode - on battery power and not plugged in - over the long weekend. Yesterday, I noticed the power light was out, so I plugged the laptop in to recharge the battery. This morning, the laptop will not boot. I have light indicators for the device being plugged in and the battery charging, plus another indicator to the right of the hard drive light that looks like a Z (?). When I press the power button, it sounds like the laptop is preparing to boot, but nothing happens. I've never had any problems whatsoever with this laptop, so I'm at a loss what to try.

what is the model number of your T400?
xxxx-xxx
is your T400 a switchable graphics model?

Thinkpad T400 won't boot neither will it accept a new OS,any idea?

I have used my thinkpad T400 for like a year and recently I hibernated it and it could not boot. I tried the battery reset and it came right on but will not boot to windows (Blue screen after POST). I tried running a new OS instalation but anytime I boot from cd, I get a distorted screen (many colourful strips takes over the screen). I really need help............................from any one.
