This is an UEFI system. Ubuntu mess it up a little bit by changing some UEFI/NVRAM stuff, (you might void your warranty by doing this) you will need to short the CL1 and CL2 pads under your RAM to fix it. You might also need to run a BIOS update from Windows (or FreeDOS - see the comments) to repair the “BIOS setup” you enter by pressing F2 while booting.
Updating the bootloader (grub) may also break the boot menu, so be careful with updating if you can't be without Windows until you have access to tools.
This is how i suggest you to installed this computer:

  • Format the drive as GPT from Linux Live
  • Install Windows 7 (if made correctly the first partition will be a 100MB EFI partition)
  • Install Linux/Ubuntu with EFI
  • Hold down F2 while rebooting, If you get in to bios reboot and hold F12. If any of these return a list where the only option is Ubuntu you need to do the NVRAM reset stated above
  • Install rEFInd in EFI/boot
  • You might have to adjust the boot order from the setup menu(F2 at boot)


The UEFI part is a bit messy, but once everything is in place it seems to work pretty well.

Thanks, worked for me after having issues with Ubuntu and centOS on my Fujitsu AH532.

Peter, 2017/04/17 07:54

Hi, I've had this for over two years now as it was, but now that I got a new laptop to work from I feel a bit adventurous again. My problem is, I seem to have blocked my bios completely. I cannot access the boot menu nor the bios settings, it just goes straight to grub, where I can boot up a fully functional Ubuntu and ElementaryOS installation. I have moved Windows to an external HDD with great effort, but now I cannot boot from it. My boot order prioritizes the HDD over USB sticks etc. but I think I tried taking it out and just leaving a stick in already without success. No change after shorting the CL1 and CL2 pads.

Do you guys have any idea how to etc. boot to FreeDOS under this circumstances to flash the bios again, maybe from GRUB somehow?

husham, 2019/03/28 12:26

Hi.. i am facing the same problem. I lost my F2 BIOS setup and my fedora 29 starts everytime. i also have windows on external usb harddrive. Can you tell me how you solved this problem or what u did ?? thanks :)

abdou, 2015/07/03 14:26

I have a ah532 and i forget password of bios what can i do for resolving this problem ? please help me thank you

mika2000, 2014/07/31 11:50

which one will be better according to u… ah53

Among the list of first steps will be to identify many of the dispensaries which have been established in your neighborhood. The most convenient way to begin this is by way of searching for Google or to search for the dispensaries making use of the Google maps.

pablo, 2013/12/08 22:42

I tried to run Ubuntu 12.04 disabling security, but does not allow disabling. I tried several combinations, even repeating the failure
The system insists that there are errors in the files of ubuntu

pablo, 2013/12/08 18:21

My computer is a samsung np500p4c-s02cl and after installing ubuntu 12.04, crashed and f2 did not work and continually turn on and turned off. Probe all shortcuts
The article was very useful, because next to the RAM memory found on plate welding two terminals that read “reset RTS”, which tried to play with a screwdriver, discharging the circuit and the computer again showed windows 8
Thank you very much for the information that solved a big problem for me

Eamonn, 2013/12/08 00:48

Hi guys, I've been having the same problem and am still confused as to what people mean by “shorting” the CL1 and CL2 pads - what exactly do I do with the tin foil? And should the laptop be switched on while I'm doing this?

Jim Murdock, 2013/12/07 01:57

Well, lads, it looks like the solution is oh so simple. Set the admin password in the bios, then all will fall into place. Jesus! I was considering mangling my motherboard and invalidating my 3yr warranty. :) Try it! It works. Now to install Ubuntu.

Timo, 2013/10/31 11:47

i got a problem on ubuntu 12.04lts and even 13.10 with my fujtsu ah 552/sl but my battery indicator just dont want to show up on my system start if i put in the charging kable it works just fine but if i restart my laptop its gone again maybe someone fixed this problem already and is able to help me

Apopas, 2013/10/08 14:51

Tested in Xubuntu 13.04.

Everything seems to work just fine.

labs, 2013/09/30 10:43

comment on fait pour reinisialiser le bios et effacer le mots de passe svp?

rotar, 2013/07/26 10:18

Is there any way to install linux in BIOS mode on this laptop?

Ottorino, 2013/07/09 15:58

Hi there,
I would like to add some information about the fact that this laptop has some feature in the BIOS which may darin the battery even when is in off state. Namely the “wake up on lan request” and the possibility to have current on USB ports even if the laptop is turned off. I went crazy in identifying those two features. Enter the BIOS (F2) and deactivate them both.

aXept, 2013/06/16 21:29

Have this with 4th generation i7.. Fucked up Win8 at install of Ubuntu. Cant get it back. First it booted directly to Win8 after install, then I runned “Boot-Repair” and now I can boot Ubuntu from Grub, but Win8 is gone. Cant see in in GParted. No Where!

Got the touchpad working with the fix in the BUG-report. But had to install gpointing-devices-settings for setup the speed of the mouse.

Optimus working great, (HD4000 and GF 620M)..

Goekan, 2013/06/09 01:15

hello, is there no other way to repair the boot menu and the bios? I deactived the the usual hd in the bios (because I thought there could be some problems while booting) and after that I installed mint on my external hd and now I have the same problem, cant access bios and the only thing in the boot menu is mint. I can enter the operating system when my exhd is plugged in without any problems. if it is possible for the os to change that, why its not possible to undo that? :S I also have warranty for the notebook but could there be problems if I would send it back?

thanks a lot

Rikard Lindström, 2013/06/09 07:40

You can try to clear your NVRAM as stated under “Notes” above.
If you can't get in to BIOS, do a BIOS upgrade.

I have no clue to what Fujitsu might say, but they might try to blame the software you installed.

glutton, 2013/06/01 20:49

Well done! Thank you! “short” the CL1 and CL2 pads help to me, back my notebook to life!

Read, 2015/09/29 17:32

guys what did you mean by `short`?

Ren Höek, 2013/03/12 16:31

I bought an AH532 on ebay but a BIOS password is set and the previous owner can't remember.

I could install Ubuntu, but it gave me an error, that grub-efi could not be installed.
I could install grub2 in chroot without an error.

Now, I still have access to the F12 Menu where I can select HDD oder DVD.
Booting from HDD starts immediately Ubuntu, without showing grub menu.
The other OS was Win 7 Home.

I'm not even sure if secure boot is activated and without access to the BIOS due to the lost password I can't do much…

Does one of the two mentioned options:
1. deleting nvram with CL1, CL2 method
2. updating/overriding BIOS with FreeDos
definitely also resets the BIOS password? And would secure boot be activated by default, maybe causing more troubles than I have now?


Rikard Lindström, 2013/03/12 17:03

Clearing the NVRAM should be enough. Just keep in mind you might lose any custom items in the boot menu.
There are probably no secure boot if it was sold with Win 7.

Ren Höek, 2013/03/13 11:28

Thanks a lot for the quick reply.
I was just about to get ready to clear the nvram, as the previous owner mailed a list of passwords, he could have used…
… I got lucky and one of them worked. So there was no need any more to risk the procedure.

As for the secure boot, it's not only deactivated but the option is missing all together.
Version of the BIOS is at 1.09.
There is an update 1.10 and a not compatible version 2.08 (is this the one with secure boot then?).

So I guess my problem, with the not showing grub menu, is grub related and I'll see into it…

Ubi, 2013/01/16 15:33

On my AH532 with Win8, Secure Boot was enabled, at first sight without a way to disable it. After searching the net I found the solution : Disabling Secure Boot works after setting a supervisor password.
After disabling Secure Boot I could install Debian Wheezy. Works almost perfect with a 3.6 kernel from the debian experimental branch (backlight hotkeys don't work). With the stock wheezy kernel the computer freezes occasionally.

Alex, 2013/01/14 12:31

the same situation with a laptop Fujitsu LifeBook AH552, but no contacts CL1 and CL2
Can someone help?

Manu, 2012/12/05 21:34

I've a NH532, little problem:
- Win8 work perfect on first HD
- install a 128GB SSD OCZ Vertex4
- install ubuntu from livecd on SSD, all ok
- next in bios, I make the SSD (with option UEFI: OCZ Vertex4”) the first boot device.

At reboot, black screen, no monitor response.
Umount hd or ssd doesn't work. I cant do anything.
When i turn on pc, no hd motor on, all is turned off, the monitor too.

What I've done?

Rikard Lindström, 2012/12/05 22:23

If you have been poking around inside the CPU/RAM compartment open up and check that there is nothing left shorting anything. And check that the RAM is correctly installed.

Try to remove both battery and the charger for a minute before putting them back.

Do a NVRAM reset in case there is some weird setting.

Manu, 2012/12/05 22:37

thank you Rikard for your answer.

I've tried everything, but I'm sure that cpu/ram compartment is good.
Problem come up when i retry to boot pc after check “save changes and exit” from bios, without touch the hardware.

However, I've tried reset procedure on CL1 CL2 pads but nothing happened.
With cl1 cl2 pads in short, PC wont power up (no power led, all is completly off, like try to run it without power plug or battery).

At least I've tried your advice, remove power and battery for some min, like ten, but same result.

Rikard Lindström, 2012/12/05 22:42

Have you tried an external monitor?

Either way, you probably need to contact Fujitsu support. Unless anyone else got a good idea.

Manu, 2012/12/05 23:11

yes, external monitor goes in sleep mode…
I'm on the Fuji support way…it's a little unbelievable…

I'll post something if some news come… :-/ Thanks a lot Rikard

Boris, 2016/11/28 12:35

Hey Manu, I know it's a little bit outdated thread, but maybe you or someone else will see that and help me. I just faced to the same issue with black screen on my NH532 and can't do anything after bios settings changes, reset procedure on CL1 CL2 didn't help me too.
I installed linux mint 18 with UEFI support (although I would like to disable it if it's possible). I was able to boot into OS using F12 boot menu, but after installation rEFInd, efibootmgr was not able to change efi bootOrder, and I tried to do some changes in BIOS which caused “black screen of dead”…

Did you find some solution in your case? Hope someone will see this somehow :) Thanks!

Finist, 2012/12/05 19:33

Please help, the same situation with a laptop Fujitsu LifeBook AH552, but no contacts CL1 and CL2 m(

Rikard Lindström, 2012/12/05 19:52

Look under the RAM, they can be quite small.

Here is a picture of AH532:

Just be careful.

Finist, 2012/12/07 08:52

Under the RAM no contacts CL1 and CL2

moerdock, 2012/11/24 10:44

Okay, I finally repaired the Boot menu. For shorting the two pads I used a small piece of aluminum foil. After that the boot menu worked again (i.e., I could boot from USB etc.) but the BIOS menu didn't. But you can fix that easily by booting FreeDOS from a flash drive (you do not need Windows!):

1.) Install FreeDOS on your flash drive and make it bootable. I used the boot image that is provided on this page:
2.) Download the “BIOS Admin Pack - LIFEBOOK A532/AH532” from Fujitsu's support site
3.) Copy the files DosFLASH.bat and FH6109.exe to the flash drive
4.) Make sure that the battery and the charger is connected
5.) Boot the laptop from the flash drive and run DosFLASH.bat

moerdock, 2012/11/30 04:00

It might be possible to repair the boot menu *without* opening the laptop + shorting the pads (thanks to Rikard again for that idea…otherwise I would have been totally lost). But I'm not totally sure if this works for you. Before you run any commands, read the whole post in order to get some understanding of what you are about to do. (I haven't tried this on any other laptop than my own one and no one else has tested it, yet. So in the worst case - at least that is how I imagine it to be - you would have to open your laptop to reset the NVRAM again…). Anyway, whatever you do, you do it at your own risk :)

First, my situation was the following: after the installation of Ubuntu, the EFI setup (it is called “BIOS setup” on the bootup screen) and boot menu weren't accessible anymore at the very beginning of the boot process - but I had a fully working Ubuntu installation.

I stumbled upon a program called nvramtool that allows you to write binary dumps of the NVRAM to your disk and the other way round. So I did the following: a) make a binary dump of my laptop's NVRAM when the boot menu was broken, b) make a binary dump of my laptop when the boot menu actually worked (i.e., after shorting the pads) c) make a binary dump when boot + efi menu worked (i.e., after b) + Flashing the NVRAM via FreeDOS). And, guess what: I can write any of these binary dumps to the NVRAM and it exactly reproduces the according behaviour. This makes me optimistic that everyone can fix their laptop without minimum fuss.

Long story, short: this may allow everyone to restore the boot and EFI menu without opening the laptop.

So, if Ubuntu has broken your boot and efi menu, try the following:
1. Boot into your Ubuntu system
2. Install nvramtool:
sudo apt-get install nvramtool
3. make a binary dump of the content of your NVRAM - this is your backup copy:
nvramtool -b nvram_backup
4. Download the following archive (beware of the crappy file hoster - don't click on any of the ads. The download button is the small one with the green arrow left to the word “Download”):
5. cd into the directory in which the archive is located in and extract it:
tar -xf nvram_binary_dumps.tar
The archive contains three files:
- nvram_fucked_up is the broken binary dump I made on my machine - this might only be interesting if you want to debug the issue.
- nvram_working_boot: the binary dump I made right after shorting the two pads on the mainboard
- nvram_working_boot_and_efi: after shorting the pads + repairing the EFI menu with FreeDOS

6. Write the - supposedly - working binary dump to your NVRAM:
nvramtool -B nvram_working_boot_and_efi
A short note here: if this one doesn't work, try at least to do the same thing with nvram_working_boot. This would still spare you to open the laptop, but you would have to rewrite the “BIOS” with FreeDOS (see the comments)
7. Reboot and try to press F2/F12 (there is very little time to press them - if you see the text ”<F12>: Boot Menu / <F2>: BIOS setup” it is probably already too late - in that case just do ctrl+alt+del and try again)
8. Please give feedback and report if this worked for you or if it made things even worse :)

moerdock, 2012/11/30 13:53

Oh my … please forget the whole NVRAM backup idea for now. It doesn't even work for me anymore. It worked *flawlessly* and *repeteadly* yesterday night (I could just copy the binary dumps around and make nothing work, only the boot menu and both menus). The difference yesterday was that after I had shortened the pads I tried everything consecutively without powering down the machine even once. And back then, the described procedure worked. Sry for the inconvenience. Maybe I can figure out how to make it work again….let's see…

Rikard Lindström, 2012/11/21 19:41

If you have multi boot with Windows you can run a BIOS update and it gets reinstalled. On the other hand there isn't that much settings worth caring about.

The computer should not be switched on when you clear the NVRAM/BIOS settings. You should remove the charger AND the battery before removing the RAM.

I blame Fujitsu, it seems their UEFI implementation is a bit crippled. Ubuntu can't read UEFI menu, but write it so it overwrites the whole thing. Also there is no UEFI shell… i think all computers should have that.

viking777, 2012/11/24 18:57

moerdock, your solution sounds quite good, but I need a little more information. Firstly neither of the files DosFLASH.bat and FH6109.exe would even copy onto a usb stick (invalid file name) until I had renamed them to remove the \ in the name. I have no idea if that will affect their operation. Secondly, exactly how did you make the flash drive bootable? I tried syslinux and was told that my Fat32 file system was not a Fat filesystem :-/. Any help appreciated.

viking777, 2012/11/25 09:49

moerdock, forget my previous post I managed to work it out for myself. I will just add a few notes to make it easier for others

Firstly the download you want is on this page: . Expand the 'Flash - BIOS' section followed by the 'BIOS Update - Admin Pack' section then download Admin Pack for your bios version.

When you get these onto your computer extract the files from the zip file. At this stage you wont be able to do much with them because they have a backslash in the filenames, so you need to change this. Just rename both files so that they are called 'DosFlash.bat' and 'FH6109.exe'. Instead of DOSflash\DosFlash.bat etc.

Next download the Freedos image given by moerdock above and extract it.

Place a fat formatted usb key into your computer, make sure you know its correct address (fdisk -l should do it) then run the following command:
sudo dd if=FreeDOS-1.1-USB-Boot.img of=/dev/sdb

The input file address (if=) will need to provided in full if your terminal is not in the same directory as the freedos download and the output file address (of=) /dev/sdb MUST be altered to the correct address of your usb key or you run the risk of deleting data.

Once this has finished mount the usb key and copy the 'DosFlash.bat' and 'FH6109.exe' to the key.

Reboot and hit f12 during the boot to get the boot choices menu and choose to boot from the usbkey.

The program bothers you to correct the date and time before starting up, they were correct in my case so I just pressed 'Enter' at each question. Once this is done you will get a traditional Dos C:\ prompt. At this point you type FH6109.EXE and press enter. A couple of minutes later the bios is flashed and you now have access to it again.

A million million thanks to moerdock for discovering and posting this answer, I am deeply grateful.

And for Rikard, I have no idea how to put my comments on this site in date order so they are not. I don't suppose it matters much.

viking777, 2012/11/21 18:38

Thanks to the author for the cl1 cl2 pad shorting idea. I haven't got my bios back from this (f2 still does nothing) but at least I can choose a boot device in the f12 menu which previously had nothing but Ubuntu in it.

Probably obvious to everyone else but I will mention it anyway, in order to short these terminals you need the computer switched on, so first remove the back, second remove the ram, third press the start up button (it won't boot, it has no ram) and fourth short the pads, fifth shut down, sixth replace the ram and seventh replace the back.

I don't know if it is Ubuntu or Fujitsu or (most likely) Microsoft who are responsible for this fiasco, but it needs to be sorted out and fast.

Tariq, 2017/08/26 16:57

I short CL1 & CL2 after removing the RAM, but the computer was in OFF state. This resulted in that now BIOS menu appears (whether you press F2 or F12) and in the “Boot Sequence” menu I only have “BISO Setup”. Rest of the BIOS works fine, detects the HD and DVD but nothing appears in the boot sequence other than “BISO Setup”. Any help in me getting back my laptop.

Tom, 2012/11/20 14:43

There's a fix for the touchpad here:

moerdock, 2012/11/23 11:00

Works (Comment #14 on the launchpad site). I need to put my finger on the touchpad such that only half of it touches the touchpad and half of it touches the plastic cover.
I used version 1.1 of the suggested driver ( Unpack the file with
sudo tar -xj –directory / -f psmouse-alps-dst-1.1.tbz

And then follow the commands mentioned in commen #14 on the linked launchpad site.

I have no experience with compiling kernel modules, but I think you need to compile the driver for every kernel update.

moerdock, 2012/11/23 11:08

Oh my…the unpack command above is supposed to have two - before `directory`. The forum software transforms two - to a –. It does the conversion even in code tags - sry.

krish, 2013/01/24 18:02

the touchpad scrolling works. installed the latest version found here it was 1.2 at the time of writing.
installed dkms as i did not have it, also linux headers generic which was also not present.
finally followed the commands as mentioned in the bug comment #14 on launchpad site. works great.

moerdock, 2012/11/15 18:27

If I remember correctly, there is just no scrolling available for the touchpad. Even under Windows it doesn't have scrolling (and the manual doesn't mention it either. See pages 26/27: (sorry, a direct link doesn't seem to work)).

But I must really say that I'm most satisfied with the laptop. The UEFI mess aside, *everything* I've tested works beautifully (multiple monitor support with HDMI, VGA, Webcam, …)

Dmitry, 2012/10/08 18:13

Thanks to the author for instructions to restore the BIOS of my laptop. It really helped!!!

Fyn, 2012/09/27 14:23

Hey there. I've also figured, that the touchpad has no scrolling. Is there any possibility to change that?

moerdock, 2012/09/09 17:41

Hello everyone,

could someone please elaborate a bit more on how reset the NVRAM?

I've removed the RAM, but I have no idea what the CL1/CL2 pads are supposed to be. Maybe someone can mark them in the following picture (RAM already removed):

Rikard, 2012/09/27 17:29

They are in the small white square straight down from where is says “FH6” on the motherboard.

user23, 2012/09/30 07:21

How does one “short” the CL1 and CL2 pads (e.g., soldering)?

Is there another way to reset the NVRAM (e.g., take battery out)?

Rikard, 2012/09/30 07:49

I used a tiny bit of tinfoil. Just be careful to not short anything else.

The battery is even harder to reach. Also it might be built to keep the settings even if the battery is removed for a short while, wich makes it a less reliable solution (not tested).

moerdock, 2012/11/15 18:30

Thanks for the clarification!
