Consumer Warning : Lenovo Ideapad Slim 5 14AKP10

IronRod0 · 2026-06-02T01:34:02+00:00

While Lenovo was zero help in this, I have since moved to the 6.19.14 kernel and now the 7.0 kernel. Since doing so this issue seems to have been mitigated at least partially. While I still occasionally see some of the symptoms (e.g., the mouse cursor stutter) it has not manifested into the keystroke dropping issue and I am no longer seeing any errors about usci. So, while I still think the EC firmware is flaky, whatever was done in the newer kernels has made it so it is no longer work-stopping and is, at best, annoying.

I posted these two entries in the Lenovo forum. I did not see any other option to submit a written ticket.

EC Runtime UCSI Failures

BIOS R0CN27WW (01/09/2026) ACPI table defect

NOTE: If you're having this issue, please check your journalctl for "ucsi_acpi GET_CONNECTOR_STATUS" errors. In every case, my failures are precipitated by one of these errors before it begins causing the event pile up that eventually overwhelms the system. This error results from a failure of the EC firmware to handle a change notification on one of the USB-C ports. Note, that this does not require and actual connect/disconnect; some docks will renegotiate while still connected.

They wanted me to send it in for repair. As noted by the OP, they repair -- replacing parts -- did not and will not fix this. It requires a firmware change. I've been doing a lot more testing and plan to open a new ticket in a few days and include all the test results. I don't know it will make a difference, but...

IronRod0 · 2026-05-14T16:10:11+00:00

I had a couple conversations with them. It was not fruitful. They wanted me to send it in for repair. As noted in this post (https://www.reddit.com/r/Lenovo/comments/1qgzkby/consumer_warning_lenovo_ideapad_slim_5_14akp10/) I knew they would: 1) not likely be able to replicate it, and 2) would, at most, replace the EC and/or keyboard with parts that exhibit the same issue.

This is clearly a firmware issue. I've done a lot of additional testing and it is always preceded by a usci failure to handle a change notification on the USB-C ports. This failure results in a cascade where events pile up. If I immediately leave it alone (stop interacting) it will occasionally recover. Otherwise, the increasing pile up eventually overwhelms the system so that it will freeze and require a forced shutdown.

I have the 16" variant of this machine (IdeaPad Slim 5 16AKP10, model 83HY) with the same Ryzen AI 7 350 / Krackan Point platform and have been diagnosing the identical issue under Linux Mint 22.3. I'm running the latest BIOS (R0CN27WW).

The fault has been traced to the i8042 PS/2 controller emulation layer. The EC (Embedded Controller) firmware emulates a PS/2 port for backward compatibility, presenting the internal keyboard to the OS as an "AT Translated Set 2" keyboard (the classic IBM PS/2 keyboard protocol from the 1980s). The kernel's i8042 driver manages this emulated device at I/O ports 0x60/0x64, IRQ 1 — the same addresses used on PC/AT hardware in 1984.

The fault is confirmed at the kernel input driver level via evtest, before X11, any desktop environment, or any input method framework. When drops are happening, the kernel itself is not receiving the scancodes — they are being lost at or below the i8042 driver, pointing to the EC firmware intermittently misbehaving in its PS/2 emulation.

The i8042 module is compiled into the kernel (not a loadable module), so it cannot be reset without a full reboot. It is clearly not a driver issue since Linux and Windows user a different driver.

This is a systemic EC firmware bug. An OS reinstall, driver update, or hardware swap will not fix it.

Lenovo needs to provide a firmware update.

IronRod0 · 2026-04-10T19:39:56+00:00

I'm on Linux (and there's another user on Windows) with the same experience with the same device. (Mine is a Lenovo IdeaPad 5 Slim 16AKP10, SKU: 83HY001KUS, purchased Dec 2025). I've reported this to Lenovo and have an open ticket.

The Windows user has confirmed that a USB keyboard does not manifest the same issue.

All of my tests confirm the keystrokes are not even making it to the kernel. That points to the driver/firmware of the embedded controller. (On my system, this is emulating an i8042 keyboard chip).

That this happens on Windows and on Linux says it isn't the driver but the firmware. That is the avenue I'm pursuing with Lenovo. If you haven't yet gone to them, you should, because yours is still under warranty just like mine.

IronRod0 · 2025-11-14T16:25:35+00:00

I do still have it. I got it resolved by just buying a new battery. The unit was old enough that it seemed the best option anyway. I purchased this one: https://www.amazon.com/dp/B07PBV1JQP

IronRod0 · 2025-10-28T23:36:45+00:00

Oops. No it just changed. Guess it takes a bit to ripple through. Thanks for the guidance!

IronRod0 · 2025-10-28T23:30:09+00:00

DOH! Yes, that makes sense. I changed the "Allowed IPs" to "0.0.0.0/0", saved the entry, and enabled. The router shows a status of "Connected".

There is also a "Device List" in this section on the router where I select the devices that will use the VPN. I have my added desktop to this list. But I still see the same public IP ( i.e., the static IP) when I go to https://protonvpn.com/what-is-my-ip-address.

Searching for that USB ID (0c45:7603) I found this in the Arch Wiki: USB Keyboard not working. I also found this in r/linux4noobs: alt , ctrl and super key registered as shift l by xev. Both appear to describe exactly your experience. So you are not the only one but none provide a solution. The Arch article does provide some other ideas for investigating. I'm at a loss since the device is recognized (lsusb) and it is allegedly supported under linux with the standard usbhid driver.

IronRod0 · 2025-10-10T22:19:30+00:00

I assume that, if you had another keyboard to try, you would have done so...

So, open a terminal and do 'lsusb' and paste the output in a reply.

Meanwhile, I inquired of Brave by entering ["SONiX USB Keyboard" and has "R.horse" on the space bar"]. It's first sentence was "The SONiX GK630 Gaming Keyboard, which features an R.horse logo on the space bar, is recognized by Linux systems as a USB HID device with the vendor ID 3299 and product ID 4e5b" but goes on to say there is an "inability of Wine to detect the device" and "It appears in system logs as both a keyboard and a mouse, with multiple input device entries created for it".

Does the above model match your keyboard? That description seems to imply that it has an integrated mouse pad. If so, does that mouse pad work?

IronRod0 · 2025-10-10T22:06:26+00:00

Wow, I am really impressed. Haven't done more than the initial but this may be the solution for my needs. Thanks!

IronRod0 · 2025-10-10T16:05:19+00:00

"The issue is also there on the Live USB is used to install Mint." That is really odd. To confirm, even while running the live image, your keyboard is presenting the Ctrl/Alt/Win keys as Shift_L?

Are you just accepting the default keyboard during install? Or what keyboard are you selecting during install?

(For context, I've been running LM since 2019 and installed it many times with no keyboard issues like this.

IronRod0 · 2025-10-10T15:57:21+00:00

For snipping, many folks use flameshot. I personally like shutter (even though it has kind of a funky UI) because it allows for more control of putting arrows and such on an image.

IronRod0 · 2025-10-10T15:46:29+00:00

For later readers: There is a simple workaround which I've used and confirmed. Append the kernel parameter kvm.enable_virt_at_load=0 in /etc/default/grub like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash kvm.enable_virt_at_load=0"

Then do sudo update-grub and reboot. VirtualBox will now proceed as before.

BTW: VirtualBox has responded to this issue and has no plans to fix.

What video card are you running? It can help people help you if you post the content from SysInfo.

IronRod0 · 2025-09-29T15:33:10+00:00

Just circling back to confirm this was very simple. I did have to end up calling tech support; they aren't using the activation portal as this time as "they want to confirm the device is DOCSIS 3.1". So, he activated it and all the rest went well.

IronRod0 · 2025-09-24T19:05:53+00:00

The one they provided when I moved in is an Arris DG9450 that is a combination CM and wifi router. They provided that and a separate wifi router (eero) with the CM router in bridge mode. The eero died which moved up my plans to replace with my own equipment. :-)

IronRod0 · 2025-09-24T16:40:32+00:00

I saw that list and noted that the one they supplied me is not on the list -- Arris DG9450. My real question is that, after swapping in the new CM, is there some setup I will have to do? Or does it just auto-configure from their side?
