I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello good people,My younger has a Lenovo Yoga 720-12IKB Laptop. For the past few days, I noticed that it's frequently showing the "Blue screen error" and restarting after few minutes of usage. So, I decided to re-install the Windows and all the drivers.  While installing Windows its showing another error. I have taken several attempts, results are same. It says:  "Windows installation encountered an unexpected error. Verify that the installation sources are accessible, and restart the installation.Error code: 0xC0000005.  Is there any solution?

The touchpad on brand new Lenova Yoga 720 does not function properly. After install, mouse pointer does not show and the touchpad does not work. The only way to get around on the computer is the touchscreen. Keyboard still works. A hard reset solves the problem temporarily. To get the mouse to show and the touchpad to work, I will have to hard reset the laptop everytime before desired use. If the computer goes to sleep, the touchpad dissapears. I do not think that the touchpad shows up anywhere in my devices. I am not sure because I do not know what the file may be called. Otherwise, I would uninstall the driver and re install. Support said to download driver off website, there isn't a touchpad driver available for download. I'd like to keep this laptop  and correct this issue. But it is a new computer so if there isn't a solution soon, I will return it instead of wasting time adding to it. Seems that many have had similar issues. Anyone any closer to an answer? Hello? Help?

I just purchased this laptop Monday, and this has been an issue from day one. I start the laptop and everything works fine, I close the lid and it goes into sleep mode. When I open the computer and resume from sleep mode the track pad does not work. the only way to get the track pad to work again is to restart the laptop. This happens every single time without fail which makes it a real PITA to use. . . I have updated the synaptics driver and generic mouse driver with no change in behavior. I have completely uninstalled all relevant drivers and let windows re-install them with no change in behavior. I have 10 days left to return this thing, so hopefully I can get this fixed before that because this form factor is great, but I won?t keep something that it obviously broken. Any help would be greatly appreciated!

My bluetooth stopped working yesterday. I ran troubleshooters etc. but they didn't fix it. I downloaded the driver from this site and installed it but that didn't work either. I couldn't see how to uninstall the original driver from device manager, when I right clicked on bluetooth I got a scan hardware option which did nothing and a properties option which brought up a small screen saying bluetooth and nothing else. Only reason I can think why it might have happened is I installed itunes the day before, I'm using windows 10, laptop is a year old. Out of ideas to fic it, any advice would be appreciated.

I recently purchased a Yoga 720-12IKB as a graduation gift. This model came with a 128GB SSD that I would like to upgrade. It would be greatly appreciated if someone could confirm the following: 1) I've found online documentation that this model takes M.2 SATA 6GB/sec SSDs. I am assuming that this means it can't take a M.2 NVMe drive? (Before looking into this upgrade, I didn't know the difference.) 2) Will this model take a 1TB drive? The sizes listed on the hardware manual go up to 512GB. But, that just could just be because that was the max offerred by Lenovo on this model. My question is can it be upgraded with a drive larger than that? 3) Assuming that this model only takes M.2 SATA drives and I can go to 1TB, this drive on Amazon seems like an excellent deal. Can anyone confirm if it will work or offer any downsides to it?  https://tinyurl.com/y4gy9zwp Thanks!

I am a very frustrated and angry customer at the moment as i keep running into Road Block and unacceptable answers.  This issue is enough to cause me to never buy another Lenovo laptop or any laptop at Best Buy!I bought my computer in July and in September i noticed a key had popped off-  the "< ," key next to the M key.  I have used the key board only when i was setting up-  now at my office and at customers i set it in downward dog mode ;-) and use a blue tooth key board.    So it is not from use that it broke.   I took the laptop into BEST BUY and was told that the key was missing a metal part on the back so they could not fix it onsite-  i would have to send it in and be without my laptop for a week to 10 days - unacceptable -  this was a month or more ago. I searched on the LENOVO website and could not find a way to purchase a single or the entire set of Keys!  I am self employed as a software consultant.   My life is pretty busy and i finally decided today to bite the bullet and ask for a call from Lenovo support.  Again i am told the only way to fix this is to send my laptop in for a repair.  I asked to just be able to buy a KEY - i am told that well they do not sell individual keys - they would replace the entire keyboard!  So sell me the keyboard and or send me one an i will take into best buy to have them replace it while i wait.  They cannot do that.   I live...

As the title says i cant boot into usb.  Via novo button i dont have the option and doing it from windows (shift + restart) yields in a message that i cant boot from USB and the only viable option is the bootloader.  The Bios is the newest one available on the lenovo homepage. But its hardly a bios.  Theres nothing i can do.  Cant change from ahci to raid (not that i wanted too) , cant change from uefi to legacy or both etc.  The only thing i can do (and have tried) is disable secure settings and fast boot.  Never seen such a restricted bios.  Does anyone have an idea how i can get it to work? Maybe a real bios with options or special drivers or settings ive to change?  Otherwise ill have to return this machine.

Hello, I've been reading up on the forums and trying to find answers. I have a Lenovo Yoga 720-12IKB model. I am trying to dual boot with Linux but I keep running into this issue where I can't change to Legacy mode. The option to change the sata controller does not appear. It is stuck on Ahci which is what I want, and when I want to change from UEFI to Legacy, the only option I have is UEFI. Does anyone have any help? thanks!,

A:Yoga 720-12IKB enabling legacy mode?

Hi,
 
I don't have a similar laptop and can't answer your questinon - but why do you need legacy mode?
 
If your SATA controller is in AHCI mode (and Windows is tolerating that) you should be able to install Linux along side. Several distros will happily boot in UEFI (and secure) mode.
 
Please explain.  Perhaps others will have suggestions.

When I took the laptop to one of the Lenovo agents in Kuala Lumpur he noticed (Which i did not notice before) that there is a Yellow box around the screen where the touch is working only out of the box and does not work inside this area.

A:Lenovo yoga 720-12ikb battery decline when charger is plugged in?

Define "decline." What percentage to what percentage. If it's 100-95, that's by design. If it's around 60, you may have battery conservation mode engaged. At least I THINK that's available on the 720.  If you're down to 20% and it's not charging, then there's a problem.

I have a new since Christmas Yoga 720-12IKB and find that the wifi is disconnecting/reconnecting numerous times per minute. It causes significant distruption trying to use the computer, with frequent errors about not being connected to the internet. Generally causes the device to operate very slow, nearly unusable. I'm not having disruption on any other computers/tablets/phones connected. I've tried a fair amount of troubleshooting but have yet to find a solution. The one workaround that I've found is that when I connect to power, the problem goes away. Remove power, issue returns. Suggests a problem with the power management (or possibly network adapter driver) but I can't figure it out. The network adapter is Qualcomm QCA61x4a. Here's what I've attempted: 1) Disable the power management feature of the adapter (uncheck allow computer to turn off)2) Run Lenovo System Update to make sure all drivers are up-to-date3) Manually updated the driver via device manager (went from .312 to .438)4) Switch roaming agressiveness to low Other than making it a desktop (needing to leave it plugged in to avoid the issue) any suggestions/resolution to this problem? Anyone else seeing the same behavior? Frustrating problem to an otherwise fantastic, fun, and fast Yoga!!! Looking for a light at the end of the tunnel....

Long list of items that have crept up on this laptop after using it for several months. . . . The touchscreen no longer works.   I have reinstalled drivers over and over again, deleted and let windows choose the driver, and have tried everything I can think of to get it working. Yet it no longer recognizes touch at all. Bamboo Ink styles works just fine, uninstalling the associated drivers did not change anything. It slowly started to work intermittently and then just quit all together. Keyboard keys just stop working  So far some seemingly random LOWERCASE letters stop working, if I hold shift I get an uppercase just fine, or if I hit capslock it will give me the uppercase of whatever letter is not working for that day, so the button itself is fine. This has happened on several different keys completely randomly for no apparent reason what so ever. The only way to fix the issue once it occurs is to stop what you are doing and restart the computer. . . Doing so might fix it for a week or an hour. In the middle of typing or clicking, or doing anything at all it decides to "sleep"    I can be in the middle of typing something, moving the mouse to click on something, or using the stylus to take notes and without warning it will enter sleep/hibernation mode. . .  I have updated the drivers to the latest that are available, I also updated the BIOS to the latest recommended to see if that might help solve some of the issues.

There are a bunch of threads in there about this issue.  Definitely look through.  I just had this issue and I managed to fix it.  GO into your device manager and see if you have an error in a driver.  I had one with the Wacom Driver.  I then uninstalled it, and had it deleted from the computer entirely (this is an option after you click delete driver.) Next, I uninstalled the Lenovo Vantage application.  Then I restarted.  Voila, my touchscreen works again.  We'll see if it lasts.  Not sure if this will work for you, but it did for me.

Specs: Lenovo IdeaPad Yoga 11.6" HD/Core i7-3689Y/4 GB/128 GB All is fine when the machine is on or in sleep mode. The problems start when it shuts down or goes to some deeper hibernation (whatever happens when the machine has been in sleep mode long enough). Then, the machine won't start up anymore, even if the power is connected. After some googling, we decided to try to disconnect the battery. This didn't help (and there was no BIOS update for this particular model) but while disassembling the machine we found out that when the front panel (power button + power light) motherboard connection was detached, the machine powered up. All was again fine until the machine shut down. So the machine can be jump-started by detaching the cable but either the front panel circuit or connection seems to be broken. Any ideas what to do? The following picture illustrates the issue: ?

Hello Have had some issues with my Lenovo Yoga 13 laptop recently. I installed AVG Tune up which was supposed to speed up my computer. Subsequently, found that it would rarely boot up properly after the log on screen. When it has rarely done so, I have managed to restore all the changes made by AVG Tune up, uninstall it and then run a defragmentation. This appears to have sped up the laptop slightly and I can now log on.  However, I have now noticed that when connected to the internet, no pages load. I do however have another laptop and phone connected to wifi where the internet does work without any problems. It says that the wifi is "connected" and sometimes "No internet" but usually appears to be connected but no pages loading.  Thanks

Hello, I have a pretty new Yoga 920-13IKB.  The USB Type A port just stopped working out of the blue yesterday.  I tried the normal stuff like deleting the usb entries in device manager, disabling fastboot and trying different devices, but nothing is recognized.  I have a USB C to USB A adapter and when I plug a USB A device into the laptop via the USB C port/adapter, that does work fine.  The USB A port does charge my phone though, so it's not totally dead. Anything else I can check on the software side?  It certainly seems like a hardware issue to me. As far as warranty support, I do have Microcenter nearby.  How does support with them work?  It looks like the USB A assembly is a separate board and is not part of the motherboard, so that should be easily replaceable.  Does Microcenter carry parts like that or do they still send it out for that? Thanks!
