--- Comment #143 from chickengui...@protonmail.com ---
I am encountering the same issue on my **Ceptor N530-04** laptop, which shares
the same hardware characteristics as the MEDION laptops mentioned in this
thread. Here are the details of my setup:
```
$ sudo dmidecode | grep -A3 '^System Information'
System Information
Manufacturer: Cepter
Product Name: N530-04
Version: Default string
```
```
$ uname -r
6.11.10-300.fc41.x86_64
```
```
$ sudo dmidecode | grep -A3 '^BIOS Information'
BIOS Information
Vendor: American Megatrends International, LLC.
Version: 212
Release Date: 04/09/2021
```
### Problem Description
The internal keyboard does not function correctly under Linux, but it works
flawlessly in Windows. Some hotkeys, such as those for backlight and screen
control (Fn+F5/F6/F7), are functional, but the standard keyboard keys remain
unresponsive. This behavior is consistent with the issues described earlier in
this thread.
### Debugging and Testing Summary
I have thoroughly tested various kernel parameters, including:
- `i8042.dumbkbd=1`
- `i8042.nomux=1`
- `i8042.reset=1`
- `acpi=noirq`
None of these attempts resolved the problem.
#### i8042 and Interrupts
The following commands were executed to gather additional insights:
- **Serio Devices:**
```
$ sudo ls /sys/bus/serio/devices/
serio0
```
- **Interrupts:**
```
$ sudo cat /proc/interrupts | grep i8042
1: 0 0 0 0 0 0
0 0 IR-IO-APIC 1-edge i8042
```
- **i8042 Details:**
```
$ sudo ls /sys/devices/platform/i8042/
driver driver_override modalias power serio0 subsystem uevent
```

### Request
Since the affected hardware seems to align with the MEDION laptops referenced
in this report, I believe this could be a broader compatibility issue. I kindly
ask for guidance on further debugging steps or any patches that might resolve
the issue.
Thank you for your efforts and support!
