Lenovo Yoga 720: My fan is buzzing.

Sun, 05 Apr 2020 20:10:18 -0700

Most likely, something is clogged, but before I open it up I'm asking for input. So the fan will buzz noisily at high speeds and if I put my ear up to it at normal speed I can hear the buzz. might not be dust because to my knowledge, dusty fans don't buzz. this started a week or two ago. Haven't opened it (yet)

either way, If I open it I'm making a guide.

I'm open to anyone, @paperboypaddy maybe one of you has ever had a buzzing fan? and @oldturkey03 any tips before I go about opening this soon?

Lenovo Yoga 720: How to reset the BIOS password?

Wed, 04 Dec 2024 11:14:57 -0700

I know this has been asked and answered for some other models but I can’t find any discussion for this specific model. I, like an idiot, set a BIOS password and forgot it after not using my laptop for a few months. I can still use it but I currently have Ubuntu installed, and I would like to return to Windows. Unfortunately I can’t do this because of the BIOS password.

I’ve popped off the back cover of the laptop but I don’t know where to go from here. I’m assuming I need to find the CMOS but I don’t even know where to begin, and I can’t find any pictures or guides regarding the CMOS on this model.

Lenovo Yoga 720: Touchscreen no longer functional after possible update?

Sat, 12 Sep 2020 22:05:14 -0700

I have had my laptop for about 5 months now, and the touchscreen stopped functioning after about 3 months. I searched this up on Google and tried all the solutions, but none of them worked. I don’t think this is a hardware issue, as this has occurred to many people after a software update? The screen on my laptop is still functioning, its just the touchscreen. My model is Yoga 720-12IKB.

Lenovo Yoga 720: Is replacing the power adapter jack possible?

Fri, 11 Dec 2020 08:15:34 -0700

Is replacing the power adapter jack possible? Would that mean unsoldering it from the mainboard, finding a replacement jack, and then soldering the jack into the mainboard? That sounds pretty adventurous.

Lenovo Yoga 720: After open bottom cover a Motherboard part attached to magnet in cover

Wed, 25 Nov 2020 19:15:00 -0700

While doing a SSD swap, I removed the Bottom Cover, when preparting to assembly I notice a part of the motherboard attached to a magnet in the cover

See where the item is missing

You can see in this picture how the part should be (but is actually loose already)

and how the cover has a magnet there (I assume is for cover detection)

After this happened the Laptop is not powering on. Can we repair/re-attached the component? If a new motherboard is required, how can we avoid from happen again? the loose component is almost in direct contact with the magnet once installed the cover

Lenovo Yoga 720: Audio just decided to die?

Thu, 15 Sep 2022 00:39:07 -0700

Okay. so today at school my audio just quit working. no explosions, no shutdowns, not even an error. I've been trying to get it to work for the past few hours with no luck.

some things I tried:

-rebooting

-disabling/re enabling audio drivers

-uninstalling/reinstalling audio drivers

-messing with settings/restore to default

any ideas? I'd rather not have to re-install windows on my laptop for the 3rd time this year.

Thanks!

(Can't watch jacksepticeye without audio; or much else.)

@oldturkey03 @pccheese @paperboypaddy @vehiclefreak409

@pccheese thanks, Heres some images. (FYI I never used the audio jack until when I tested it)

Lenovo Yoga 720: USB-A port stopped working. (USB xHCI Compliant Host Controller)

Tue, 14 Nov 2023 11:30:16 -0700

Hi - Unsure why USB-A is can't be detected anymore.

Tried reinstalling drivers
Even removed the drivers manually so that correct driver can be reinstalled
Reinstalled windows 11 from the scratch
Ran Lenovo softwares for diagnostic, no issue found, all drivers are Up-to-date
Tried to boot from USB, but port not detected

I think all possible combinations have been tried in BIOS

Tried turning switching 'Always ON' flag in BIOS
Disabling 'secure boot' to boot from the USB
Restoring BIOS to previous version
Upgrading BIOS
Resetting BIOS to default

No other option seems to be related to USB-A in the BIOS.

Also tried:

I tried "USB Root Hub - Properties - Power Management and check if the box that says "Allow the computer to turn off this device to save power" is unchecked."

Also tried:

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Did anybody else faced this issue?

Thanks

This device cannot start. (Code 10)

Lenovo Yoga 720: Changing from RAID to AHCI

Mon, 28 May 2018 08:50:39 -0700

I barely know anything about these to things except for that RAID is causing a problem with linux. I'm pretty sure you are supposed to use RAID with at least 2 storage devices while my laptop only has a single SSD. would I break something doing this? I know I lose my stuff doing this so beforehand I will backup.

@danj @nick

Can't call me out for taking a picture of my screen this time! you try taking a screenshot in the UEFI!

Lenovo Yoga 720: intermittent failure of keyboard & trackpad

Sat, 03 Jul 2021 11:53:26 -0700

The built-in keyboard and trackpad on my Yoga720 intermittently stop working. Rebooting makes no difference, and I tried installing latest drivers. Some minutes or hours after failure it spontaneously starts working again. I have opened up the computer and can’t see any obviously loose connectors or crushed cables. My guess is its a hardware fault and am contemplating buying a new keyboard & trackpad. Does anyone have other ideas?

Hi,

would it be possible to swap the 1080p screen that came with my Yoga 720 (15IKB) for a bigger resolution 4k screen ( bought from an official reseller)?

On this site it does not show hot to replace/ take off the screen.

Regers,
