[FIXED] Closing Laptop lid causes CPU 100% usage in Linux

"Hey there! I hear you're having trouble with your Acer Aspire netbook. It sounds like you're experiencing a BIOS issue that's causing the internal lid switch to repeatedly send a "closed" message to the OS, which is maxing out y
our CPU.

The good news is that there's a simple fix. You can either update your BIOS or disable ACPI. Updating your BIOS is the preferred solution, but it's a bit more technical. If you're not comfortable doing that, you can disable ACPI instead.

To disable ACPI, open a terminal window and run the following commands:

sudo nano /etc/systemd/logind.conf

This will open the logind.conf file in a text editor. Find the line that says LidSwitchIgnoreInhibited=no and change it to LidSwitchIgnoreInhibited=yes. Save the file and close the text editor.

That's it! Once you've done that, the lid switch should no longer be sending a "closed" message to the OS, and your CPU should stop maxing out.

Just a few things to keep in mind: disabling ACPI may affect your ability to control the display backlight, and the operation of the (physical) power button may be different. Also, if you ever decide to update your BIOS, you'll need to re-enable ACPI.

I hope this helps! Let me know if you have any other questions."
