Fn Key is disabled on boot - Cannot enter bios

Hi there,
I'm running an x240 series machine running Windows 8.1 pro. I need to enter bios. I have tried butting it from PC settings, but there is no uefi option or any menu or boot menu option.
Hence, the only option was to enter via the traditional route. However, the moment I restart the machine, the fn key green light immediately lights up, effectively locking the button. When I interrupt the normal startup process via the "enter" key, I cannot enter bios via the fn + 1 key since the fn key is disabled or locked.
Is there a reason or a solution to enable the fn key?
Update: Felt like a complete moron. The F1 label was so small on the keyboard that I missed it. Just press the mute option. You will see a tiny F1 label on it.

There is also a way to access UEFI BIOS through Windows 8.1, though it's buried pretty deep.
Go to >PC Settings
>Update and Recovery (it's at the very bottom)
>Recovery (again, at the bottom. the next step shuts down you Windows session, so save your work)
   Click 'Restart now'
the OS shuts down and then displays some 'metro style' options.
   Click 'Troubleshoot'
then     'Advanced options'
then     'UEFI Firmware Settings'
then     'Restart'
then you hopefully will be presented with the options that you are looking for. (works on anything running UEFI Windows 8.1)
Have fun!

Windows 7 Stuck At BIOS Cannot Enter BIOS or Change Boot Media

My laptop has no problem before. Recently I try to install Windows XP. First attempt fail, so I change SATA at BIOS from AHCI to Compatible, success. However the partition that I want to install Windows XP to is not available.
So just to test I choose my Windows 7 partition. Since it want to format the partition, I cancel the installation. After restarting windows, it stuck at bios. I restart again and change SATA to AHCI. Restart, still stuck at bios. This time I cannot enter BIOS, recovery or change boot media. Assuming the boot sector has corrupt, will reseating the cmos battery will fix this problem. Please help. Thanks in advance.
Solved!

hi kiebloom,
Yes, you will need to boot without the HDD to try and access the BIOS again. If you're able to access the BIOS using this method, reload the BIOS defaults by pressing F9 then press F10 to save and exit.
From here, you can try to:
1. Re-insert the HDD and press the OneKey Recovery button to reinstall Windows 7
2. Create a recovery disc for Windows 7, format the HDD and downgrade to Windows XP
3. Dual-boot Windows 7 and Windows XP (see this guide)
Best regards,

Satellite C660-2C3: Cannot enter BIOS

Hello,
I enabled the Quick Boot Function which skips the Logos and only boots from HDD, but now I need to install a 32bit Windows for School, but I can't enter or reset the Bios.
I tried every button combination I can think of.
Is there any way to remove this feature again without taking it apart?
The existing Windows is not the Original one, so no toshiba software is installed.
Thanks for help.

HI

I have tryied to press "F2" button several times , but no response. I tryed to press "INS" key at the beggining , then "F2" key , but still no entering to the BIOS menu. If i wrong , pls tell me where?!

T430s neither boots, nor enters BIOS anymore

Hi all,
A quite tricky challenge:
I got a new T430s a few days ago. It worked nicely, with Windows 7. I started working on it for some days, with many reboots. I could also enter into BIOS. Now I created a backup image of the Windows-7 partition, and the partition called like "sysdrv", using an Acronis TrueImage boot CD. This went fine, the system booted from CD, and created a backup to an external USB HD. After having finished, I closed the Acronis program. Since then, the T430s doesn't boot anymore. It hangs with the following message:
"Initializing Intel(R) Boot Agent GE v1.3.81; PXE 2.1 Build 091 (WfM 2.0)". The cursor is blinking underneath.
I tried pressing ENTER at the beginning, which works. But then in the menu, I can select either F1 to enter BIOS, or F12 to choose temporary boot device, but both options lead me to the same text as above, with blinking cursor. The option F10 to run diognostics works, and doesn't find any error.
We tried with another bootable CD, no effect. The optical drive quickly sounds, but after some seconds the system hangs with the same message.
So, in conclusion: I cannot boot Windows 7, I cannot enter BIOS, I cannot change the boot order. Even Ctrl-Alt-Delete doesn't work to reboot. I can only press the power button for 2 seconds to shut it down.
Thanks for any suggestions
Solved!
Go to Solution.

I am guessing your Acronis backup you did was cloning the drive and not a full HD image to the external drive. If you clone and don't use advanced or responded incorrectly your original HD was modified by Acronis Trueimage. It may not longer be marked as an active boot partition and never boot again without fixing it.
As I recall the tools are on the boot CD and you should be able to fix it. NOTE: Window 7 partition is NOT the normal boot partition on Lenovo Win 7 systems. Its the "SYSTEM_DRV" Partition set as Active.
Good luck, you can call Acronis for help with their tools on fixing this and I would if you're not well versed in partitions and managing them. Once you screw it up its far harder and may be impossible to fix over the phone of via forum posts!!!

T61 at boot everytime enters BIOS (unable to skip BIOS)

I have a T61 with Windows 7 64 bits installed,
T61 did work fine for several months untill last week,
but now when booting immediately after the message to enter BIOS press F1 there is a message entering BIOS setup and then BIOS windows appears, by pressing F10 or ESC Windows 7 starts without reporting problems,
apparently there are no errors reported and I am unable to understand why BIOS setup window appears,
I did several attempts to restore BIOS to default values etc. (hoping to avoid the reported problem) without success,
when booting T61 enters everytime the BIOS Windows and I have to press Esc or F10 to continue normal boot,
How can I restore the original behaviour (i.e. booting without entering BIOS windows) ?
Has someone experienced a similar problem and found a solution ?
Thank you for help.

Have you checked the date and time to make sure they're correct?
They will enter bios if the date isn't set or if the cmos battery is bad, but I've never seen a T61 behave like this otherwise.

Satellite L840/020 - Cannot enter BIOS after enabling fast boot option

I have a Toshiba L840/020 (PSK8LA-020007) notebook. I recently installed an Intel 330 Series SSD and Windows 8 Pro RTM 6.2.9200 MSDNAA on it and enabled Fast boot option in the BIOS (Boot speed > Fast).
Now I can not get into the BIOS no matter what I do. I tried pressing power button while holding down F2 (as suggested by few other forums) , up on failing that I tried all F keys and Esc, but nothing works. I also tried repeatedly pressing F2 while booting, connected an external USB keyboard and pressed F2 on that , but no matter what I do I cannot get into the BIOS.
When I go to Download section of Toshiba support > Windows 8 64bit, I can also see a BIOS update for my notebook, but when I try to install that I get the following error :
Error
Flash process will be terminated!
Current platform have secure boot feature, it must provide NV storage location by IHISI interface.
Please contact OEM BIOS engineer to add the feature.
Without this IHISI interface, the authenticate variables will be modified or cleared by flash process.
If you understand the risk and still want to flash.
You can add the following setting in platform.ini to ignore error.
[EngineeringErrorDisable]
SkipSecureBootProtectionCheck=1
OK
I didnt change platform.ini and flash, without first seeking help from the community.
Please let me know how to get into the BIOS. Thanks.

Hi
Try firstly INS button and then F2 button.
Then you should be able to access the BIOS I recommend disabling the fast boot in the BIOS if you could successfully enter the BIOS.
Regarding the BIOS update.
I checked the Toshiba AU driver page and it seems that the BIOS v6.20 is the same like for Win 7.
I think that the BIOS update should be done running the Toshiba preinstalled system since Win 8 is not officially on the market yet and from my knowledge there are some big restrictions updating the BIOS running Win 8

U310 Touch Cannot Enter Bios Setup with NOVO Key

I am trying to enter bios and have tried the following and failed.
1) Through Advance Setup in Windows UEFI Firmware
2) FN F2 / F2
3) NOVO Key
The NOVO gives me an option to Bios Setup but it just boot me back to Windows 8.1.
I need on-site warranty on this laptop in Hong Kong. Is the warranty international?
Solved!

Hello,
I don't have an IdeaPad U310 myself, but I'm wondering if you hold down the F12 key after applying power, does that give you a menu from which you can get to the BIOS? That worked for me on a IdeaPad U410.

E531 Will Not Boot - Cannot Access BIOS.

Hi everyone, I'm running out of ideas here and I'm really hoping that someone out there can help me. I have a ThinkPad E531 which I cannot get to boot into Windows, or even into the BIOS. The screen just goes blank (but it's still on) and then hangs right there. I've tried various fixes already - draining the power by removing the battery and power cable, and then pressing and holding the power button all kinds of different lengths of time.
I've also tried re-seating everything I possible could to no avail (RAM, HDD, CMOS Battery, Processor, Optical Drive, Fans). As well I've also tried getting into the BIOS by booting with the HDD and optical drives disconnected. Tried swapping memory to a different DIMM slot.
What boggles my mind here is that there seems to be a consistent limit to what I can and cannot do:
If I try a "Normal" startup...
When it first starts, the Lenovo splash screen loads fine.
Once the splash screen goes away, it just hangs on the blank screen.
If I tap [Enter] on startup...
The Lenovo splash screen loads fine
When the splash screen goes away, the "Startup Interrupt Menu" appears
I can even hit [Enter] to Pause the default "Resume normal startup"
From the "Startup Interrupt Menu",
If I hit [Esc] (Resume normal startup), I get a white cursor in the upper-left corner of the screen which flashes twice, then freezes and the system hangs.
If I hit [F1] (Enter BIOS Setup Utility), the white cursor in the upper-left corner flashes for about a millisecond, then disappears, and the system hangs.
If I hit [F10] (Diagnose Hardware), it hangs instantly with the cursor in the upper-left corner.
If I hit [F12] (Choose Temporary Startup Device), it brings me to the Boot Menu/Application Menu.
From the Boot Menu,
If I select either the HDD or the ODD with a bootable disc, the screen just goes blank and hangs.
If I hit [Tab], I can switch the the "Application Menu".
From the Application Menu,
If I choose the first option (Setup), the screen goes blank and the system hangs.
If I choose the second option (Diagnostic Splash Screen), the diagnostic splash screen actually loads:

U310 with linux cannot enter BIOS

Hello,
I cannot enter my BIOS on a U310 no matter what I try, including soft/hard reboots, power plugin', Fn+F2, "holding B while powering on" combinations and other recommendations seen here or here.
I guess I should mention that I do not need/want Windows to the point that I even do not know what kind of Windows came on my U310 when I bought it, so there is a GNU/Linux (Fedora 17) installed, and the only problem I had was sorted as I wrote here. I have been happily using my laptop without problems otherwise.
My question is - how do I regain access to my BIOS now?
As I already stated, I do not care that a "One key restore..." button does not work for me, or similar single button functionalities are not perfect, but being completely cut off from BIOS is a totally different set of problems.

Update: the only hope of functionality left for me in this situation is that an USB DVD with a liveDVD can be choosen for boot by pressing Fn+F12, that gives me a boot menu, so I should at least be able to boot/install another operating system in the future, which is just enough regarding that functionality for me.
The problem with accessing BIOS remains, though, and I am looking forward to consult with a good lawyer after I try to figure out does this malfunction has anything to do with the UEFI recently forced by Microsoft - I somehow feel that at least in the EU courts it coud be presented as highly illegal to tamper with customer's freedom, and prevent me to use my laptop in a reasonably functional manner if I do not want Microsoft Windows on it.

Cannot enter BIOS (F2) w/Apple USB AluThin Keyboard --- Win XP w/NO PS2

Greetings,
I love my Apple aluminum thin USB wired keyboard with my Windows-based PC, but...
I'm d*mn frustrated.
I cannot enter my BIOS by pressing the F2 key at start up.
I also cannot press 'any key' when trying to boot from a disc.
The keyboard is unrecognizable to the PC until the Windows XP Pro OS loads, then it works perfectly, typing on it now.
The F2 button works as normal once XP Pro is loaded.
My mother board does not have any PS2 ports (it is an Intel DG33LT board). So I cannot plug in a PS2 based keyboard to enter the BIOS or boot from a disc.
I've read all about going into the BIOS and turning on the support of Legacy USB, etc. However, this is useless, as I cannot enter the BIOS in the first place.
I'm trying to upgrade my computer that I use primarily for producing my income via product design, 2 GB of RAM just doesn't cut it with Illustrator and Photoshop running at the same time.
I'd like to install Vista so it can support the 8GB of RAM I purchased. Can't boot from the DVD to install it.
Any suggestions?

Yes, easy solution.
I figured the obvious culprit was the keyboard itself. I was curious if there was a software fix, etc... rather than going to the store and dropping $20 on a keyboard just to access the BIOS/boot cd.
Well, I dropped the $20 on a junker keyboard, and it all works fine.
Also- do not correct my online etiquette.

USB Keyboard not working at boot to enter BIOS (Neo2-LS 865PE)

Hi,
I just upgraded to a new usb keyboard for my computer but it seems that I can't use it at boot time...When i was using the PS/2 KB I was able to enter bios and select the multiple boot selection...now with the USB one I can't! Is there any option I have to set in the BIOS to support USB KB at boot time ? If I let go the boot sequence up to Windows, I can use the USB KB in Windows...it is detected and everything seems to be ok!
Thanks!
My Motherboard is a Neo2-LS 865PE...

The BOSS is always right Yup, just enable what he said and you will be fine.

Cannot enter BIOS or boot from LSI MegaRAID SAS 9271-8i

Hello,
I have a LSI MegaRAID SAS 9271-8i installed in a C220 M3 (in PCIe1). When I go to CIMC, I can see the adapter there and I can create RAID arrays. I can set the first logical drive to be the boot drive too without a problem. If I boot from ESXi installer it will see the disks and install to them.
The problem is, the server won’t boot from the disks, and I don’t see any problems for the card’s BIOS during boot. I have disabled the on-board RAID controller.
How do I get the server to boot from the RAID card?

Hi,
Glad to see the issue is resolved now (I never saw your post before) was it that the OptionROM for the PCIe card was not enabled or the boot order was not properly set?

I bought a new msi amd motherboard it cannot go into cmos BIOS setup it just says entering setup and it doesnt go any further, I have the pc down to barebones memory cpu and msi board.

I have the same issue. After having pressed the Del key during booting up - the computer hangs with "Entering Setup" shown in the bottom left of the screen.

T430s cannot enter bios

Hi,
My T430s system has windows 7. I accidentally enabled UEFI boot and now the computer cannot get into both windows 7 and bios. When I press F1, the screen becomes black forever.
I flashed the bios to the latest version but the problem stays.
Any ways to solve this problem? Thanks.
Bo

Thanks! Spent the entire night trying the idea but unfortunately it did not solve the problem. Now it reports real time clock error and prompt F1 for entering setup. But when I press F1, the screen becomes black. I waited for a long time, no BIOS still. Tried a couple of times, same thing happens every time.
This is frustrating and ridiculous. What can I do now? The whole thing seems really silly.
