Stuck in uefi (bios) setup after wakeup

I recently encountered something strange when using my laptop. I'm using Windows 8.1, and when I finished using it last night I pressed Fn + F12 (Zzz). This is usually how I put the laptop in sleep mode when I'm done using it.
Usually it wakes up without a problem but this time it woke up to the UEFI (BIOS) setup screen. I thought that was strange but I chose discard changes and exit. It exited and went right back to the same setup screen. I didn't press DEL to enter setup or any other key, it just automatically went back. I then chose Load Optimized Defaults and saved the changes. It exited and went back to the same setup screen. It seemed like it was stuck in some kind of an infinite loop.
After looking online, I decided to try disabling fast boot. After saving and exiting, it then brought me to the Windows login screen where I logged in and saw that all of my programs were still in the same state as when I had put the computer to sleep.
I have since re-enabled fast boot and I haven't seen the problem again yet. However, I thought this was very strange as I haven't seen anything like this before. I don't understand why temporarily disabling "fast boot" fixed the issue and why I have never seen this happen before.
Has anyone ever heard of an issue like this? Why would "fast boot" prevent the computer from waking up? Why doesn't it happen again now that I've re-enabled fast boot?

I don't know why but thanks for sharing the information.
May let us know your model and BIOS version?

    just wondering how can i overclock my CPU w/ this rig coz i cant see any threads regarding this mobo, also i cant open up the BIOS of my system i have a windows 7 64 bit ultimate. hoping for some good advise.  

    Recommend to do all the bench tests at the original auto/stock/default settings, then you have something to compare later results with. In Reply #10, I have given some basic pointers at which to start. Soon as CPU V. is taken out of auto, you will lose any power saving advantages at low use & idle. Another quick & dirty way to do it is to set the CPU V. at the industry recommended maximum of 1.400v's, & start to increase the CPU Ratio up one step at a time until it fails to boot the OS. Keep in mind, load overshoot will usually spike the VCore past the 1.400v's at times in varying amounts. For gaming, OC'ing RAM is a wasted effort. After extensive testing, it made almost zero change in gaming performance on it's own.

  • BIOS setup menu is missing in my G580 after installing fedora....

    Dear sir,
    I bought a Lenovo G580 [59337032] laptop about a month ago.
    It had no OS installed. I installed Fedora 17 in it.
    But after installing Fedora, I can't be able to access the BIOS setup menu by pressing F2.
    And also my boot order rearranged.
    While pressing F12 during boot, the boot devices list appears.
    But the first entry is Fedora, 2nd is Ethernet, 3rd is HDD, 4th is DVD drive.
    I found a similar problem in this forum. But the solution [disconnect the HDD and press F2 during boot]
    of that problem did not work in my case.
    I also deleted the recovery partion of lenovo.
    My BIOS version is 62CN34WW
    How can I fix my BIOS? 
    Now my OS is Windows7.

    Dear Sirs!
    Have the absolutely same problem with one difference - installed OS was Ubuntu 9.04.
    According to recomendation HDD mode was setted as "сompatible" (IDE). After rearranging
    disk to 3 parts: /, /swap and /user/home and setting up system I have find that BIOS setup
    are unaccessible and system won't boot up (Non system disk error).
    From LiveCD and USB, both Ubuntu and Windows XP SP3 system boots and work fine,
    HDD read/write accesible.
    Local serviceman told, that they have no possibility to reprogram BIOS flash by themselves
    and it will take 2-3 month to obtain new motherboard or whole laptop for exchange. This is
    absolutely unacceptable for me, because my job depends on the health of the laptop.

    Thanks in advance for cooperation!

  • K9N2 SLI Platinum raid setup after bios flash

    Hi
    I'm building a new system based on K9N2 SLI Platinum. Apart from a new 80 GB sys. HDD everything else is reuse from another MB (MSI K9N Platinum).
    Here is what is puzling me: Before trying to install WinXP i flashed the bios to 3.2 because of the included updates to the raid bios. Flashing went well, however in my setup I want the 80 GB HDD to be non-raid and the two 320 GB HDD to be raid1. I've set this up in bios so that only channel 5 and 6 is enabled for raid and would expect that the 80 GB HDD (channel 1) would show up as a normal sata HDD when starting up. But it doesn't - it is listed as 0.0 xxxx after the "press F10 to enter raid setup" message?
    This is strange because I had the same HDD setup on my old MSI K9N Platinum and there the 80 GB sata HDD was shown as a "normal" disk and not as a "appendix" to the raid list.
    Because of this I have problems installing WinXP on the 80 GB HDD
    Any suggestions?

    Hi BOSSKILLER
    Thanks for your quick response.
    Quote from: BOSSKILLER on 12-August-08, 00:14:44
    Well, leave the 80GB only and install XP over it.
    Then connect other two HDD's and enable RAID for them.
    Unfortunately this didn't help. As soon as I installed the Windows nVidia RAID SW it prompted med that it had registered  the 80 GB disk as a new disk that wasn't a member of any RAID. This happened everytime Windows XP was started.
    The trick was to add the 80 GB disk as a Spanned disk using the nVidia RAID BIOS setup utility. Install Windows XP (again) and the Windows nVidia RAID SW and setup RAID 1 on the other two sata disk.
    I don't think this is a great setup but it works. I hope that MSI will fix this issue in a later BIOS upgrade. It would be nice if the enabled/disabled for sata RAID setting actually worked.

  • Cannot Access BIOS or Boot Windows 8 After Changing UEFI BIOS to Legacy BIOS

    Acer V7-751, 500G HD, Windows 8.
    I changed the BIOS settings from UEFI to Legacy BIOS when I was working on a problem. Now I can't even get into the BIOS (F2)
    or change the Boot Order (F12). All I get is an error "Operating System not found". I can boot with a Win7, Win8, or Win8,1 DVD. I suppose I could boot with just about anything else bootable as well.
    The problem seems to be caused because it's set to Legacy BIOS and Secure Boot Manager as default #1 boot device. Legacy BIOS
    can't boot a Win8 drive that has been installed under UEFI (Secure Boot). I have to change the BIOS back to EUFI to boot the WIn8 drive, but the only way to change the BIOS is from within Win8. It's a very flawed way of doing things but it's the way it is.
    Does anyone have any suggestions that they KNOW work. Please don't Google answers. I've already done that. And please (please)
    don't tell me to power on and press "F2" (or any other key) to go into BIOS. If I could do that I wouldn't be posting.
    Once again, I cannot get into the BIOS without going into Windows first. I cannot load Windows because the install was done
    under UEFI. I cannot change from Legacy to UEFI because I can't get into the BIOS.

    In this case, I flashed the BIOS with a newer version of the BIOS/Firmware and that returned everything to the Defaults (not Legacy BIOS). I believe you could also flash with the same version. I don't think you could flash with an earlier version, but no harm
    in trying it. if you've flashed the BIOS previously, you may be able to restore the previous copy. It all depends on the manufacturer and how they handle flashing the BIOS.
    I wasn't able to, but you may also be able to boot from a correctly formatted USB drive with another OS (Windows XP/Vista/7) because Legacy BIOS allows you to boot from external devices. Essentially, you need to be able to boot from a valid OS that is not on
    the Hard Drive that was configured using the UEFI BIOS setting.
    Please let me know if you have any more questions, and I'll do what I can to help. If this solves your problem, please mark my post as the answer. Thank you.

  • LENOVO ideapad z580 uefi(bios) seems to be "untouchable"

    So heres my problem, i wont lie my z580 aint new one , its been guess already 2-3 years; well for the first year, remember being able to change uefi settings, but then it somehow was unchangeable; however i didnt think that it ll be an issue, i mean no big deal, at least not worthy to register in forums or contacting support center as m tooo lazy; well then 2-3 days ago i accidentally deleted windows 8 boot entry, and its not big deal as with cmd u can back it up, however i tried with shift + reboot automatic repair first as i knew if i turn pc off i wdnt be able to boot as no bios option available and thought automatic repair is guaranteed option however it turned out that automatic repair cdnt fix it and it made me reboot, and thats how i got stuck and not being able to change anything, whenever u boot it says bcd is missing, and only available option is esc=change uefi settings which ll just reboot and endless loop, i tried every combination keys to try to discover that bios key, nothing, and here is the problem even if i try to repair with windows 8 cd it wont boot it, it ll just keep saying bcd is missing as i cant prioritize cd rom over hdd; so after rampaging for 5 hours i discovered some new option, it turns out that novo button actually works but instead of pressing it when laptop is booting u have to press it while its turned off, and then 4 new menus but after trying them all i discovred that they dont function as well at least half of them , as bios setup and normal startup just tries to boot from hdd and loop again, and recovery and bios leads to one key recovery; then again after 654876123 times trying all of them, i got mad again and with choosing bios i rampaged on keyboard again and which lead me to advanced options, howcome ? simple, it turns out that after chosing bios u have 0.2 to press f8 or arow keys at least to access that option, else it ll automatically go to one key recovery; and 9 new option available ; and i tried every single of them again, 6 of them were useless same loop, 3 of them were safe mode (with cmd,with network) and i thought to myself i had solved it however 3 of them were literally same, i tried each one and only thing i got was blank desktop and cant use any commands (windows +r, alt + ctrl +del ), just had to wait, at least thats what my cursor said , so i obeyed but yet again another error which said unable to copy something like boot64.efi as partition is full, which surprised me as i had +100gb free space, but then there was browser option which was ridiculous as it said that i cd change source path (lol, source path rofl,not destination path, but source path of that file) but with browsing i discovered that it aint lying it somehow created some partition with 5mb size or something and it cdnt copy it lol so again i stuck, only thing i needed to fix my **bleep** was to be able to access cmd not even win 8 cd or boot option, so only solution was to go to technician and attach my hdd to another laptop just to be able to access to **bleep**ng cmd !!! and now i m trying every single thing to try to change uefi but m unable even with easyuefi, i mean is it normal ?   

    I am not sure why this works, or if it will work for your machine, but with my computer I read somwhere that this can be fixed by removing the battery with the machine off and plugged in.  Now hold the power button for a bit (20-30sec?) unplug and continue to hold (20-30 again), still holding plug it back in and hold (same amount).  Let 'er rip.  When you remove your finger it should start up.  So let it get going for a second and then put the battery back in.
    I also read somwhere else that someone is able to fix this by simply holding the power button for a good while with no battery and no power cable. 
    From what I understand, the method I suggested is what is used to reset a router.  It has something to do with flash having a tendency to hold its state, so an extra long 'reset hold' is needed.  No idea if that applies in this case though.  All I know is that my battery now charges to 100%, and when it sometimes borks when I change batteries, I can fix it this way.

  • G580 Laptop BIOS setup not starting

    Hello,I've a Lenovo G580 Laptop (2nd Gen PDC B960, 2 GB, 500 GB, DOS) When I bought it came pre-installed DOS, and then I install Windows 7 ultimate (32-bit, i didn't know at that time, 2nd gen PDC are 64-bit). My friend recommend me to disable UEFI from boot setup before installing any non-genuine OS, so I did disable that. My laptop is working fine, but all of a sudden it started to do random mouse freezes, surprisingly pressing ALT+F4 works like a charm to make mouse work again (by mouse I mean pointer actually, I'm using Touchpad, i don't think its a h/w related issue)I think may be it's because any virus/malware or whatever that was, and also I was planning to change my OS to Windows 8 (it's after 10-11 month of purchase date), so I decided to format anyway, instead messing up with mouse freeze problem.
    Now strange thing happen at this point -I'm not able to start my BIOS setup, nor able to use quick boot option (to select various bootable device option from list)I try to press recovery key (small button near power button), that open recovery module properly (no glitch/error).
    but unfortunately I don't have any backup made previously so no use of recovery module.and then I restart my laptop, then I press F2, it shows the first screen of BIOS menu, but my system stuck there (unresponsive state), i've no option else directly turning it off by holding power key for few seconds,..and then no boot menu F2, F12 still unresponsive.means whenever i open recovery module it able to open F2 menu (not F12) but that stuck too.
    else it just completely ignore F2, F12I'm not a computer noob (not flaunting), but I spend last 4-5 hours looking for a solution for it, but couldn't find any solution by myself.
    although my laptop is not in not working state. somehow I manage to install windows 8, but it's really weird that I can not access BIOS menu, my laptop is no longer in warranty period so I can experiment with it any way I want. 

    Hi envolt,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that G580 is not entering the BIOS menu and hanging at BIOS menu it at all it enters it, performing flee power should resolve the issue; below are is the step to perform Flee Power.
    Remove the battery and any other peripheral device connected to the computer. Hold the power button for 10 seconds and then connect only the AC Adapter and try to turn ON the computer and enter BIOS menu.
    If the issue persists even after performing Flee Power, I would Strongly Suggest Calling Technical Support for Assistance this is the only available option to get this query resolved, Click here to open a link where you can select the country and get the exact contact support number, I’m sure they will be a great help.
    Do post us back if the issue still persists.
    Best Regards

  • Confusion about UEFI/BIOS and GPT/MBR compatibility issues

    So a user said in another post that they were NOT able to boot in UEFI mode and install Fedora even though it is UEFI compatible.  But this person was able to useLegacy mode and install Fedora, and furthermore, was able to "keep the Windows partition."  I'm guessing that means that Win 8 that came with it, which would be installed in UEFI/GPT mode, correct?  I'm specificly referring to the Y510P but from what I understand *every* laptop that comes preinstalled with Win 8 must be UEFI/GPT.
    So the way I understand it is that the installed Fedora is in "BIOS"/GPT mode rather than "BIOS"/MBR mode because you can't have both GPT and MBR on the same disc.
    I have just started learning about this UEFI/BIOS and MBR/GPT nonsense, and it's going to drive me crazy until I finally understand it. So I guess what I'm asking is:
    1) When I get my y510p I assume it will be in UEFI/GPT mode. Can I install non-UEFI distros alongside it as I take it was done with Fedora?
    2) If I install a linux distro alongside Win 8, do I have to worry about compatibility issues with a drive that is in GPT format? Or does the MBR/GPT issue have nothing to do with it, so I don't have to worry about ever changing my drive to MBR?  
    For example, I read that Win 7 must be installed either as BIOS/MBR or UEFI/GPT.  This can not be mixed and matched.  This means that if I could not get the Windows 7 installer to boot in UEFI I would have to install as MBR.  This also means I would have to format the drive and reinstall Win 8 on the MBR.  
    So my question is do other OS's like Linux have these restrictions?  (For example, if a particular distro will not boot in UEFI and therefor MUST install on MBR)
    3) I have a pendrive with YUMI installed with a ton of distros/tools/Win installs/etc. (It is a USB boot tool like unetbootin that allow you to add multiple bootable images.) When I tried it recently on my dad's laptop.  I have used it many, many times with my older computers, none of which were UEFI.  It works great.  Now that I've had a recent encounter with my dad's ASUS Windows 8 computer (not with the y510p yet) I found out that UEFI seems to be complicating the crap out of things (for me, at least.)
    So when I used this computer, I noticed that when I boot (with legacy mode enabled) and enter the "boot selection screen" in order to boot with USB, I have two options a) UEFI:"name of usb" and b) "name of USB". The UEFI option would NOT boot, but it would boot without the UEFI: option.
    So does this mean that I am booting in non-UEFI mode and once I have booted this way and choose a distro to install that it CANNOT install in UEFI mode?  I recently saw a tool called Rufus that I have yet to try that has an option to set the bootable USB to UEFI, so that would possibly work if I wanted to install a UEFI compatible distro (Arch linux is what I'm wanting.)
    4)  If installing a UEFI compatible distro (such as Arch) requires that the USB device be able to boot in UEFI mode has anyone been able to do this?  Has anyone even been able to boot a device in UEFI mode to do *anything* such as run a live linux?  
    I'm 99% sure I would be able to boot in legacy mode and run a live linux (because I did so on my dad's computer) but the problems arise when I consider how to INSTALL.
    I would really like to know the answers to these questions (as scattered as they are.) Any help would be appreciated!

    (I started learning about BIOS/UEFI and MBR/GPT the hard way a few days ago by trying for hours to install Windows 7 on my dad's Windows 8 laptop because I could NOT get Win 7 installation to work...it kept asking for drivers before I could install until I finally used the Windows USB install tool, put the stick in a different USB, AND formatted the drive as MBR because Windows 7 would NOT install on the existing GPT drive until I used diskpart.exe -clean. And I have read that Win 7 64 bit will work fine on a UEFI/GPT setup. I used the Windows 7 USB boot tool which did NOT give me a UEFI: and regular option. It showed up simply as "name of usb" without a UEFI in front. Since I read that Windows 7 must either be in BIOS/MBR mode or UEFI/GPT mode that this drive would not boot in UEFI mode, and I don't know why...Although I believe I read that Win 7 cannot be installed from a USB in UEFI/GPT mode, only BIOS/MBR.  UEFI/GPT mode requires a DVD install but I did not have a drive to test this.)

    I have a Y510p which is running dual boot Windows 8.1 and Arch Linux.   I think that it is strongly advised to do plenty of reading ahead of any install if you will be using UEFI and Linux so that you understand all the issued before making critical changes to the existing system.
    Yes, if the machine comes with Windows 8 (as mine did) then the disk will be formatted with a GPT partition table (instead of the old MBR partitioning scheme), and will boot using UEFI. If you are going to try to keep the existing Windows 8 system and add Linux then you will need to keep the disk with its GPT partition table and partition structure, but you can shrink the Windows 8 C: drive to make space for the Linux partitions that are needed ( a root partition and at least a /home and/or /opt partition and possibly a linux swap partition also ).  If you want to boot the Linux install via UEFI then you can simply add the required boot directory to the EFI System Partition (ESP).
    However it is very important that before trying to do any linux install that you switch off Fastboot from within WIndows 8 (or 8.1). Also most Linux distributions are in some difficulty booting using Secure Boot, though a few such a Ubuntu and Fedora are supposed to be able to do so. Hence it is much easier to work with Linux if Secure Boot is first switched off from the BIOS settings menu.
    The order of operations that I used was;
    1) Switch off Secure Boot from the BIOS - and boot back into the Windows 8 system to check that it boots OK.
    2) With Windows 8 running go into the settings and switch off Fastboot (which does a hybrid suspend when it shuts down instead of a full normal shutdown - if you don't do this then the memory gets overwritten when booting Linux in the future which means booting back into Windows will fail). 
    3) Reboot back into WIndows and check all is well, and if so then use the disk management facility within Windows 8 to shrink the C: drive to make room for the Linux partitions.
    4) Reboot to check Windows 8 still boots OK.  
    5) If you are going to update to Windows 8.1 then do so, and then update everything once it is booted (it is a huge update and takes ages!). Once done then you will likely have to update drivers for the graphics cards, the clickpad and possibly the wireless chip and ethernet chip. I found that I needed to get drivers that were newer than were available on the Lenovo website, by going to the relevant hardware manufacturer website (eg for synaptics for the clickpad). Then spent a week or so in the evenings getting Windows 8.1 configured the way I like it.
    6) Then I did a lot of reading about the various options for the boot manager that would suit a UEFI boot for a dual boot system for Windows 8.1 and Arch Linux and there was a choice of Grub, Gummiboot, rEFInd, and others - and after reading the details I decided on rEFInd as my boot manager which can boot not only any new Arch Linux install but automatically finds the Windows UEFI boot files and presents the options in a nice graphical window once the system gets past POST at bootup.
    7) It was important to check which partition was the ESP and to know what partitions I needed to create for the Arch Linux system.  Then I went ahead and booted from a usbkey to a uefi install system, and very carefully proceeded with a standard Arch Linux install, being particularly careful to know where to put the rEFInd boot manager files and the kernel and initrd files. Also I used efibootmgr to write the appropriate NVRAM boot entry in the motherboard memory so that the uefi boot system knows where to find the rEFInd uefi boot files in the ESP.
    8) Once complete the system boots to Arch Linux as the default, with a nice Windows icon which you can select with the arrow keys within the boot timeout period (default 20 seconds).
    I noted also that it is possible to create boot stanzas in the rEFInd boot manager config files which allow rEFInd to chain load other Linux systems or even other bootloaders if you wish - so it is very flexible. So if you want to you could install a grub standalone set of diretories/files so that if the normal linux boot fails then you can select the grub icon from rEFInd and chainload grub to boot either the same Archlinux install, or point to a third linux distribution if you have more partitions containing that third install which might be Ubuntu or Mint or ....
    Either way although getting to understand how uefi boot works is a learning curve it is actually generally simpler than the old legacy BIOS boot. With uefi you no longer need an MBR on the drive, and only a suitable EFI System Partition which has to be VFAT formatted. However if you want to have one of the linux distributions booting from legacy MBR then you need to create an MBR at the start of the drive - so you would need to move the start of the first partition and create a suitable sized Master Boot Record otherwise MBR boot can't work. If you do that then of course you have to be careful if the Windows partition is the one being re-sized that it doesn't mess up the Windows boot! However since using uefi to boot rEFInd allows a chainload to grub/gummiboot or other bootloaders then there should be no need to mess with MBR booting if you go down that route.
    If you are interested in rEFInd then the author Rod Smith has a good set of documentation that describe the details at http://www.rodsbooks.com/refind/
    He is also the author of a really excellent disk partitioner for GPT disks - http://www.rodsbooks.com/gdisk/
    Clearly it is necessary to read up on the boot facilities available for any linux distribution that you plan to put on the system.
    One nice thing is that uefi boot with an efistub supported kernel build is really fast on the Y510p. My system boots Arch linux in about 7 seconds to the KDE login prompt once the POST is complete and that only takes a couple of seconds.  Of course Windows is much slower once it is selected at the rEFInd screen and takes somewherearound 40 seconds or so to boot, but at least Linux is super fast!
    Anyway I hope that this helps.
