Lenovo Yoga Pro 2 Flex :: BIOS Update Now System Won't Boot
Dec 4, 2014
I wanted to do a fresh install but my restore files are in Windows 8 and I wanted 8.1. I used my 8.1 pro disk and created a bootable media for installing using USB. I had to go into the BIOS and change it to legacy before it would see the USB drive. Went ahead and deleted all the partitions then created a single new one for windows. The installation worked flawlessly then I went ahead with the driver installs.
The very first driver was the firmware update. The system updated the firmware without any issues but once it rebooted I only receive the following message "Default Boot Device Missing or Boot Failed. Insert recovery Media or hit any key. The select 'boot manager" to chose a new boot device or to boot to recovery media. When I go hit any key it leaves me with no boot options probably due to them being legacy options. I've tried F2 on startup to get into the bios and change it back to legacy but this never works.. I have also tried F12 trying to get it to let me select the startup drive.
I have a severe problem (I guess) after the latest BIOS Update. Windows 7 freezes during startup.
I own a 64-bit Lenovo FLex 2 15D with AMD A6-6310 and R4, 4GB RAM and a SSHD (8GBSSH). I purchased it without OS and installed Windows 7 - which worked fine so far.
I yesterday updated the BIOS with version 9FCN23WW (for Win7 and Win8), the latest BIOS update. A mistake, it seems.
After Reboot, I first had to disable Secure Boot in the BIOS, because it would not let me boot at all. I figured out how to get into the BIOS-Setup to disable this (press Enter 2x, press Tab when in the Boot Menu to access the "Apps Menu", then "SETUP").
Now Win7 begins to start up, but freezes during the startup process (the splash screen with the win flag freezes and looks a bit strange. I used the "protected mode" Windows Startup and saw that the process always hangs when loading "amdkmpfd.sys".
That is basically it.I guess I have to find a way to re-install the previous version of the BIOS.
Now about what I did to fix this (poor, but I tried):
If I try to start from a Win7 installation CD-ROM (actually it is one for Dell PCs, but I guess that is not the problem) and press a key to boot from CD, Windows loads files, shows "Starting Windows" and at a certain point again just freezes. When I -do not- press a key, WIndows Boot Manager shows up and mentions that "Windows failed to start (etc.)" "File: EFIMicrosoftBootBCD" "An Error occurred while attempting to read the boot configuration data."
I can't even boot into Linux on a USB stick, because the Windows "Error Recovery" won't let me when I try (just offers to boot to Win7 in protected mode - it could be that it fails immediately and jumps back to Win Startup).
I just formatted my yoga 2 pro, downloaded the drivers and ran the Bios Update. I followed the instruction on the read me, ran the .exe, clicked next/ok until the laptop restarted and if I'm not mistaken a red menu with a progress bar showed up. At that point I left and when I came back a few minutes later the laptop was turned on, the screen lighting was on but the display was black, the keyboard backlights were also turned on and everything else was off. The lights on/near the power button that signal if it's turned on and plugged to the AC are turned off.
It's been like this for over 30 minutes now, no signs of progress. I'm not very keen on turning off or unplugging the laptop while flashing the BIOS, but at this point there's not much else I can do.
My new Yoga 2 Pro has a secondary display connected through the micro HDMI port. This worked like a charm initially. But after upgrading to newest Windows 8.1 (this is done automatically) it no longer outputs anything to the micro HDMI port. Display and cable is fully functional. But even though the display is powered on, the computer fails to register it and apparently it cannot output anything. Seems like the micro HDMI port is non-existing.
After the windows upgrade I have tried to uninstall / reinstall the display driver. I have also upgraded the Intel drivers to Win 8.1 versions found on the Lenovo support site (including BIOS 76CN38, Intel HD 4400 display driver 126.96.36.199.3496 and chipset 188.8.131.526). But nothing seems to work.
My laptop (Ideapad Flex 15) updated and restarted this morning -- upon which I lost all KB function. I could not log in since could not enter my password. I plugged in a wireless USB KB which works. How to restore laptop KB function?
After doing a system backup the intel wireless n7260 disappeared. I reinstalled it under device managers action and the driver got installed as (2) and not working, meaning the driver 1 must be actually there but is not visible and also not working. I therefore cant get an internet connection or see any available wireless networks. How to get this driver working again?
I bought this laptop 1 WEEK ago. 2 Days after purchase it crashed. Unable to get back in... tried turning on and off numerous times. Finally able to reacess, but system completely reset itself to factory settings. Thought it was a glitch..Its a brand new computer.. 3 days later, same problem. Finally able to get back on, through system repair, but all data is lost AGAIN. System update search states that "there has detected a serious problem loading language files and cannot continue. Please contact Lenovo Support Center" Also, touch screen no longer works.This is a brand new computer!??
A couple of days ago, and quite some time after the latest BIOS upgrade I noticed that under windows the keyboard and mouse on a unified receiver wouldn't work anymore. I normally use Linux and didn't notice the malfunction because Linux does find the USB and enables it (as seen in logs) and they work.
First I thought it's some weird Windows driver issue but the thing that is different is that when booting (grub) or in BIOS - the keyboard and mouse don't work there as well indicating that apparently BIOS doesn't enable it at boot.
I am now not sure whether the BIOS upgrade did this or something else. Since it works under Linux I can hardly consider it as a hardware problem.
What works under Windows anyway is charging USB devices - so apparently something comes through that port.
I purchased a new Flex 2-15 online the past week. The model name shown on the back is "20405". Manufacture date is May 12, 2014. The User Guide refers to a "Novo Button", which is shown in diagrams as being on both the left edge and the right edge near the front. Neither location has a button of any sort. The right edge has a pinhole in the supposed button location. A curved arrow icon is next to the pinhole. I have an inkling this may be some sort of factory reset button. Lacking the Novo button, what is the procedure for accessing the features which the manual says are accessed by pressing this non-existent button?. That is, BIOS, and/or the one touch image backup/restore system?
When i boot the computer to windows, a message pops up saying that i have to not charge the battery up to more than 70%.
It's says that i have to set up something in power consumption options but when i went there i didn't see something relevant to the battery lifespan(in french). Kow to set this up ? between i'm always on the sector (AC).
Yoga 13 bought in 2012. Was working fine with 128 GB / 4 GB. Tried adding another SSD and 8 GB RAM (Crucible), and now I get the message "Default Boot Device Missing or Boot Failed. Insert recovery media and select any key."
I went through the bios and Information says "Hard Disk: Not Detected". Have tried F9 factory reset. No response. What else can I do?
I have recently bought a Flex 2 15 and want to instal Win 7. I created a bootable Win 7 usb stick with the tool from Microsoft and it works just fine. The problem is, no matter what I change in Bios or Boot manager, The laptop doesn't boot from usb. All I get is the normal Win 8.1 installation.
I just flashed the new BIOS v38 and now USB charging does not work. I have checked Energy Manager settings, they are correct. I even uninstalled and reinstalled the EM software with no success. How to get USB charging working again?
I just bought a brand new yoga 2 11 only 10 days ago. I used it this afternoon, closed it up and walked away for a couple hours. This evening I tried to wake it up, and it's stuck on the Lenovo screen. After a while, it said Preparing automatic repair. It spun for 10 minutes and the screen went black. I forced shutdown and walked away, completely frustrated. Now if I try to reboot, all I see is the Lenovo screen. Nothing is happening. What can I do?!
I've been having problems with the dreaded "black screen" when starting my Yoga13 (but only somethimes!). To try and narrow it down, as there seem to be so many things that can cause this, I went into the Bios settings from "F2" and setup it up to ask for a "Power on" password before starting windows.
What I have discovered is that when the black screen occurs its BEFORE the Bios asks for the initial "Power on" password, ie I cannot see the box asking for the password and so Windows has NOT yet started to load. To overcome this, I just press the power button to switch off the system, wait 20seconds and then it will usually start.
Once past this, no errors ever occur on the windows side.
Using windows 8.1 i've uptaded my intel hd 4000 drivers, restarted and lauched a 3d game. After few seconds I tried alt+tab and then everything got stalled and eventually with lots of artifacts on screen I've got a message about a system crash and that system now is dumpin information to a file and next it will restart. In that moment I've panicked and hard reseted (so memory dump hadn't finished).
So now when I try to boot - for a quite some time there is a black screen and then a list of boot options pops up:
Normal Startup , bios setup , boot menu .... but the keyboard is not working at all.
So after connecting a usb keyboard I entered boot options and there iv noticed something strange:
Link to image
EC version is messed up.
Keyboard is not working at all and some other things.
On top of that when I'm choosing normal startup the windows "wheel" is turning but its newer getting to boot.
I get the error in the Title after i tried to flash the latest BIOS update for the Z510. I can press ok and then get into the boot manager but i cant choose anything there. Also I cant boot from a Disk with e.g. XP on it.
I also tried the Inside BIOS crisis mode (fn+r) with the BIOS file on my USB drive but it doesn't work and tries to access the file on the USB drive but boots normally instead to the error again. (Couldn't try it with removed battery as I have to remove the whole back to remove the battery on the Z510).
I just bought Z50-75 with AMD FX7500, 8GB Ram and FreeDOS. I installed Windows 8.1 Pro, and they pulled some drivers during the installation, and I went to Lenovo sight and downloaded all the rest (graphics, camera, etc.), after each installation the computer restarted normally and all was O.K. The last drivers that I saw on the site were BIOS drivers, and I downloaded those to and it started the installation after which it said:"The system will now restart for changes to make effect", and it did, but, it would not boot up after that, all it did was show me this on the screen:
And I tried both of the options (the second one with the Windows CD inside), but it just stays where it is, no effect.
I can enter the bios and change the settings, but none of them seem to work because this is the maximum where it will go, the only difference is when I change from AHCI to Compatible mode, it restarts and than I have a blank screen, I have to use the One button Recovery to get back to this one from the picture above...
Yesterday, I saw on the Lenovo System Update app, that I had couple critical and optional updates. These were the updates:
WER Patch Lenovo Comm Utility Lenovo Power Management Driver ThinkPad Power Manager Intel WLAN Driver BIOS 184.108.40.206
There were couple updates on the Windows Side. I ran all of them in one session so I can't really say if windows messed up something or the System Update is responsible but since yesterday I can no longer shutdown my x230t i7 Win 7 Pro. I closes the desktop and then it gets to the screen where you'll see a spinning wheel and the words "Shutting Down":
But it will hang there forever and never actually shuts down. I have to press and hold down power button to shutdown.
I just did a BIOS update the other day. No idea what version it is. When I booted it said it "detection error on HDD...". I have since reset the BIOS options to default, and now it boots to a DOS-like boot screen that shows the ATA HDD0 drive. But selecting it and hitting enter just flashes the screen and nothing happens.
When I attach a USB thumb drive with Linux, it shows up in the options on the DOS-like boot screen, but selecting it won't boot from it.The laptop is now totally uselss and I'm losing days of time and it's a major problem.
I just updated my bios on my Z510, and now the only boot options i have is network boot, something that i don't use. I used the bios update tool that Lenovo is distributing from the drivers page for my PC.
After updating to brand new BIOS from Jan. 19th I cannot boot anymore into Windows 8.1 - always get INACCESSIBLE_BOOT_DEVICE. Tried to repair using a Windows 8.1 USB Stick, no success. Even downgrading to 1.08 did not work as well!
I bought windows 8 .1 machine from factory. Then I had local shop install 8.1 on larger ssd. I just performed latest bios update and now machine will not boot. I am sure this is uefi related but I am not knowledgable in that area. The boot parameter returned to me by the shop was "legacy only" and secure boot was disabled.
Well, didn't check before installing Macrium Reflect Professional but it detected 7 (seven) partitions in my Yoga2 13 (Not Pro) as follows:
1 - WinRE_DRV 1GB total 313MB used - NTFS Primary 2 - System_DRV 260MB total 28.5MB used - FAT32(LBA) Primary 3 - LRS_ESP 1GB total 497MB used - FAT32 (LBA) Primary 4 - NONE Unformated Primary (?) 5 - Windows OS 422GB total 44.58GB used (C NTFS Primary 6 - Lenovo 25GB total 2.46GB used (D NTFS Primary 7 - PBR_DRV 15.75GB total 12.46GB used NTFS Primary
All Yoga2 13 are like that from the factory or Macrium created some of them? If they are like that from the factory what each of the partitions have inside (other than, obvlously, the #5 Windows.)
In creating an image for restore in case one is needed which ones I should include in the image?
