Lenovo Yoga 2 Pro Flex :: New BIOS Breaks USB Charging
Jul 26, 2014
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 know, that F10 it's a Windows-only laptop and Linux not officially supported on it by Lenovo,
Have purchased just yesterday a new IdeaPad F10, Spanish edition
Have successfully installed Ubuntu 14.04.1 x64 on it. Have preserverd the possibility to boot Windows and Recovery.
The installation was smooth, every things was working fine, but:
After the closing the cap, the laptop was going to hibernate, and then no way to resume or get it on.
Have tried to press the power button for a 8-10 second then disconnect the AC cable.
When doing this the power indicator becomes white for around of 30-40 seconds then off, during this nothing is happens, the screeen is black, no fans no HDD activity noise. Only if pressing the Windows logo on the screen it´s become giving a some sound, not a beep but it hears like... a rattle or something like..
It is dead now? I belive that disconnecting the battery can solve this but it´s mean loosing the warranty, because it´s necessary to remove the back screws. Or it´s possible to reanimate it by the other way?
I have the issue that my newly bought Yoga 11 (three weeks ago) is charging whenever it seems to feel like. The first time I have charged it, it went up to 92 % telling me its now in power state and not charging. This happened triple. Yesterday my Yoga was beneath the 50 % mark and I plugged in the powercable, the same again: not charging. I unplugged the power cable and at 0 % and a shutdown I booted it and it charged perfectely up to 99 % without moaning. I unplugged the cable and at 77 % the same again, I plugged in the power cable and it charged up to 99 % again.
Is this a bug (battery problem) or a feature (thresholds for a long living battery)?
My battery is at 0% available, plugged in charging, but it never goes about 0%. I've tried resetting the battery gauge in Energy Manger 1.0.1.49 but that only runs for a few seconds and reports that the gauge reset is complete. I've also disabled the ACPI control in device manager then enabling it and the icon appears to be charging but only for a few seconds then stops. Having conservation mode on or off doesn't seem to make any difference.
The latest BIOS is installed and I believe I have the latest version of Energy Manager.
Earlier today, my Yoga 3 Pro decided to stop charging. When plugged in, the battery continues to drain as if it was not plugged in. I have tested the A/C adapter by plugging in my phone with a micro USB and that worked fine, and the USB charging slot works when my wireless mouse is plugged into it, so I assume it must be the strange Y3P USB cable that is not working.
Would a normal USB to USB cable work for charging my laptop? If not, how do I replace that "kink" USB cable?
I just have a few questions about how conservation mode and express charging work. These two are located in Energy Manager under settings.
Conservation mode keeps the battery percent at 55-60%. How is this done? Does the computer discharge until 55% and then charge back up to 60%? Also, if the computer is off, but the AC adapter is left in, will the computer still remain between 55 and 60%? Are there any detrimental effects on the battery?
Express charging allows the computer to be fully charged in 100 minutes. How is this done? Why is this feature not enabled by default? Are there any detrimental effects on the battery?
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?
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.
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.
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.
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 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).
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?
Is there any way to boost volume on Yoga 13?? I have my system volume and video player volume maxed out and it's STILL not loud enough. No it doesn't have anything to do with what I'm watching, and no, nothing to do with the player. Windows Media, VLC, and Divx have been tried.
I bought a Lenovo yoga 13 a couple days ago. the yoga freezes 1-2 times per day. the Screen Shows the frozen application, the Keyboard, touchpad or mouse didnt Response.
I watched into the logfile and DptfPolicyLpmServiceHelper is the last entry before the Crash. I uninstalled the Dynamic Platform and Thermal Framework, but it doesn't work....
I got my new Yoga Pro 3 and it is looking and working great except from the two fingers tap which does not. This is a real bummer since I use it all the time on my mac and Asus devices.
I´ve got a problem when I connect the yoga 2 pro with my TV (8 year old sony, full hd) with HDMI. The picture doesn´t fit into the screen, it is too big. I tried changing the resolution of both yoga and tv and at the Intel graphics driver I can´t change the scaling option. H
I paid $60 just for some recovery discs to recover my accidentally formatted Yoga 2 Pro. The discs came with no instructions whatsoever, and using them is weird. First of all, there is two disc 1's, no disc 2, yet there is a disc 3 and 4. Support confirmed this is normal. There is also no prompt between discs 1,1, and 2, so despite making my best guess at when to switch, I can't confidently say I'm not screwing things up.
After the whole process completes, the bios can't find bootable media.
I had bought yoga 2 pro from Malaysia three weeks back. And I had traveled back to India last week.The PC was working fine till yesterday. Yesterday while I was working suddenly the system hangs and I had to hard reset. But after that the system didn't boot up. It shows boot device not found. I have switched it off and tried booting using restore button and opened the bios it shows that HDD not detected.
Similar kind of issue I faced two times before but if I hard boot again it worked fine.
Where I can get the windows 7 Drivers for the Yoga 11s. After a format and clean install of windows 7 i have a bunch of yellow bangs in device manager?
I just got the Yoga 2 Pro and it seems like a great laptop / tablet. I have one big problem: the touchpad is near-unusable for me. It seems like I'm constantly activating the switch app gesture and just cannot use it.
How do I turn off all of the gestures on the touchpad so that it just functions like a normal mouse????
I've got a Yoga 11s which is barely a few months old and hasn't seen much use. Having the same problem - it won't power on or charge (powers on only when plugged in). In Lenovo Energy Manager battery status shows "Good" and charging status shows "Battery Connected". WIndows power management icon however, shows Plugged-in, not charging. Never had that problem before either, but it came with the power-on failure so I guess they're related.
I cannot get the Y2P to shutdown or sleep. When I try to shut down it powers off but after about 2 seconds it turns itself back on and boots up. Same thing happens when I try to sleep.I've tried pretty much everything I could find online including the following:
-Turn off wake on lan on the network adapter -Turn off auto restart on windows errors -Updated bios -Updated drivers -Disabled all non microsoft services -Factory reset of the OS
Went through every device in device manager and turned off "Allow this device to wake the computer"powercfg /lastwake (shows nothing).Shutting down isn't a huge deal as holding down the power button will eventually turn it off. But not being able to sleep the laptop when I close the lid is a deal breaker as the battery constantly drains.
I just got the Yoga 2 Pro, I also have an older Thinkpad 65W 20V AC adapter with a ThinkPad Slim Power Conversion Cable, so it will fit, but is it ok to use? All the specs match except my new Yoga 2 adapter doesn't have the wattage listed on it.
I just bought a Lenovo Yoga 2 pro and installed windows 8.1 by itsef. During Windows 8.1 initial setup I was able to use keyboard to type in PC Name, but after that the keyboard and touch pad was not working/no any response any more. After Windows 8.1 lunched the keyboard also no any response. I have to use touch screen soft keyboard. But when laptop in BIOS mode (turn power off and press a small round button next to power button) the keyboard was working fine. So I think that the keyboard hardware is ok, but some thing iwas wrong with Windows 8.1 software issue. I also un-selected all on Easy of Access->Keyboard section in Windows 8.1.
I have a Yoga 2 pro and the powered usb port was supposed to work as a charger even with the laptop turned off, but it is working just with the computer on, I already tryed to change the in the energy options the selective suspension of the usb and also in the device manager, I deselect the "computer can turn off the device to save energy" but nothing worked...
