The motherboard's manual should have the best instructions specific to it, but in general, use an antistatic mat and antistatic gloves to protect the components from electrostatic discharge. Use a pea-sized amount of thermal paste, and always use the spacers that came with the motherboard. That can help prevent a short.
There should be two buttons on either side of the duplexer. Press the buttons to release the auto duplexer and remove it from the printer. Then, press the button on the duplexer cover and open the cover.
First, try reseating the HDMI cable in the ports of both the laptop and the monitor. Then turn your monitor off and back on. Make sure that the monitor's brightness settings are turned all the way up. If these don't work, try using a different monitor, cable, or HDMI port. This can help pinpoint the source of the problem.
According to that product's documentation, there are some performance limitations. 1. For some devices, the HDMI Switch may not work when only one input device is powered on. In this case, please turn on two or all the three input source devices to provide enough power. 2. This HDMI Switch supports up to 4K/30Hz. If your input device (such as PS4 Pro) runs 4K/60Hz, it won't work. In this case, please lower the resolution on your input device. 3. This HDMI Switch can't switch automatically, only by manually pressing the SELECT button. 4. For PS4 Pro (and, presumably, PS5) this HDMI switch supports up to 2160P-YUV420. 2160P-RGB is not supported yet.
You can't reset a Chromebook without the login information needed to access it. You may, however, try to perform a clean installation of the Chrome OS. To perform a clean install, first create a bootable USB with the Chromebook Recovery Utility found at https://chrome.google.com/webstore/detai...-recovery-utili/jndclpdbaamdhonoechobihbbiimdgai Then, use the bootable USB to wipe the Chromebook clean and reinstall Chrome OS. Put your Chromebook into Recovery Mode by pressing and holding Esc + Refresh, then press the Power button. A prompt will appear that will ask you to insert the bootable USB drive.

In the Allowed Programs window, click the Change Settings button. Then, scroll down the list of apps until you see your gaming app. Check the “Home/Work (Private)” and “Public” boxes for the gaming app and click OK. Then, try your game again.
The device manufacturer tends to be the authority on the repair of their products. If Acer is saying that the keyboard needs to be replaced, there's a good chance that there is no other option. If both Linux and Windows show that the F keys are malfunctioning, then I also believe that the problem is hardware-related and the keyboard needs replacement. Please keep in mind, however, that laptop repairs can get steep in price, and the cost of the repairs may end up being more than the laptop itself worth.
Check to make sure all the phone's pending updates are installed. Then try turning off the phone, reseating the storage card, and turning the phone back on. If none of that works, a factory reset may stop the unusual behavior.
