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.

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!

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?

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.

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.

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!

I have a customer who has the above model Lenovo laptop. She hooked up an an external display via HDMI using a HDMI-mini HDMI adapter connected to the mini-HDMI port of the laptop which was working fine for more than a few months. She was using the Best Buy Insignia brand. All of a sudden, the external display no longer detected the laptop and the laptop didn't detect the second display. I remoted in and checked everything out and it seemed OK as far as drivers and such so, for simplicity sake (and after having her verify the external display was working wtih other devices), I had her pick up an Insignia HDMI-miniHDMI cable and just bypass the adapter. She tried that, no luck. So I remoted in again and uninstalled the Intel and Nvidia drivers and reisntalled them using the drivers from the Lenovo website. There was no change. I've done some extensive research about this issue in the forums and there have been other models with similar issues and the fixes were... using a different cable, different adapter, or both. These were mainly solutions to solve the problem of secondary displays not being detected at first, not fixing the issue of it working just fine for a while until one day... nothing. Has anyone come across an issue similar to this?

If i search for the Synaptics Pointing Device in the device manager of windows, the mouse is displayed with the error code 24: "This device is not present, is not working properly, or does not have all its drivers installed".
 
It is possible, that the mechanism for screen flipping disabled the Pointing device?
Or is it possible to deactivate the Pointing device with a secret key combination?

I have two most old laptop models, Dell Precision M6300 & Dell Latitude D630.
When laptops is docked to replicator potr dock stations D/APR (PR01X) or D/DOCK (PD01X) - bigger one model with DVD port,

headphone jack port not working under Windows 10 Pro x64 installed on both laptops.

On M6300 previously was installed Windows 7 Ultimate and on D630 was Windows 8.1.
On Dell  M6300 on Win 7 Ult. headphone jack port worked properly.
On Dell D630 on Win 8.1 I'm not sure due I do not used this on it (more years ago when it was on Win XP headphone jack port worked properly)
So when Ms start delivering updates do Win 10, I did it on doth laptops, everything on both models working fine, but only this headphone jack port in D/APR (PR01X) or D/DOCK (PD01X) wouldn't like to work when I'm dockind Dell M6300 (D630 I docked only
for test if on this one jack port will work or not) but not working too like on M6300.

Okay, so I got an error message a while ago stating that "Power Surge On Hub Port: A USB device has exceeded the power limits of its hub port", I ignored this message for a while until my USB, wireless mouse receiver stopped working completely (BTW at this point I had a WiFi adapter, Bluetooth receiver,wireless mouse receiver, wired keyboard, webcam and I had my phone and tablet both charging off of the PC), I then unplugged my phone and tablet from the computer (assuming that they were taking too much power) but this did not work, I restarted my computer with only a keyboard and mouse plugged in. After the restart neither of the device were working so I unplugged the mouse and tried it in a different computer, it didn't work here either but it gave the "USB device has malfunctioned and Windows does not recognize it" error message. After that problem, all of my USB device have slowly started to stop working in both of my computers and I can't figure out what the problem is. So far, as of this post my WiFi adapter has stopped working along with my wireless mouse, wired mouse, wired keyboard bluetooth adapter and webcam.

I have ASUS P8Z77 ?V motherboard and the front USB 3.0 headers are not working when I plug in a USB 3.0 device. When I plugged in my Kingston USB 3.0 Flash Drive into the front USB 3.0 header it didn't work. As in, when I tried to move a file into the flash drive, the drive disappears and it makes that USB unplugged sound. But if I connect it to any back USB 3.0 ports, it works fine.

But, if I plug in my Scandisk USB 2.0 Flash drive into the front USB 3.0 ports, it works without any errors.

This only happens with USB 3.0 devices and it has to be connected to front USB 3.0 ports.
I have installed all the latest drivers and updated my BIOS to the latest one. I have checked if USB 3.0 is enabled in BIOS.

I asked to my friend to help me. He has AMD rig with ASUS M5a99X EVO motherboard, which has a front USB 3.0 header. We installed all AMD drivers for his rig updated everything, the front USB 3.0 ports worked fine. We manage to transfer all the files at full-speed on to the Kingston 3.0 flash drive without any errors, so I know it?s not my PC case?s USB 3.0 cable at fault.

Hi dino1989,

I checked the motherboard manual and it talks about only 2 USB 3.0 ports; appears that it offers 2 USB 3.0 port connectors at the back panel:


Please take a glance at the motherboard layout. Connectors highlighted (11) are 10-1 pin USB56, USB78 & USB910. These connectors are used for USB 2.0 ports (9 ports) at the rear panel. If the 2 USB ports in front are also connected to there, they may comply with USB 2.0 specification and would support upto 480 Mbps connection speed. (Tried but could not find anything in the manual that gives a clue about the source of the USB ports in the front).
However, you may go to 'Onboard Devices Configuration' and try setting 'USB 3.0 Controller' as [Enabled] in 'BIOS' to see if that gets the USB 3.0 ports functional in the front panel. This 'Enables / Disables' the USB 3.0 controller.

To access 'motherboard BIOS', you may want to refer to this manual: http://dlcdnet.asus.com/pub/ASUS/mb/...5A78L-USB3.pdf

Hope this helps. Do reply with the findings.

Device Encryption option is not available for Windows 10 Home. (The option is absent when searching under settings. BitLocker is offered for Windows 10 Pro upgrade, which costs considerably more).According to internet (Microsoft, StackOverflow), Device encryption requires TPM 2.0 and InstantGo. Seems like Yoga 700 does not support InstantGo (checked settings with powercfg /a) Device Encryption is important for a lot of people who have security concerns, but prefer not to upgrade to Pro for BitLocker. I would love for you to help solve this issue for me. Thanks,
