Backup. Backup. Backup. (Just to be sure you hear me). According with datacent  this is the sound of a Toshiba laptop drive with bad heads making clicking or sweeping sound on boot up. [s2]. This one [s6] instead it is not the record of a motorbike but what you risk to listen in a near future. (see note). As spotted before the clicks you are ...
Clicking indicates a mechanical problem with the drive, or a faulty platter where the heads cannot align properly. They are seeking to the limit defined by the drive's firmware. The drive is defective; time to get a replacement.
Looking at your text and comments, I think you may misunderstand what a "hard drive is". The hard drive is the bit inside the computer which stores the information, not the laptop itself. You need to replace the hard drive in the laptop - which is probably worth about US$50-US$100 excluding labour - you don't need to replace the whole laptop. [ I get the ...
The Inspirons have a magnetic catch for when you close the laptop lid. They use the magnetic sensor to work out when the lid is closed so the screen no longer needs to be on. Your phone is triggering the sensor.
I’ve not tested the MacBook. The Dell XPS 13 I have in front of me right now appears not to even trickle charge on USB-C at 29W even when the laptop is turned off ... it wants 45W. I’m going to leave it overnight but I am not confident it will work at all.
I do not know how to do exactly what you're asking for, but I have a pretty good alternative. You can make custom shortcuts, omitting the need for using the mouse at all. The shortcuts I'm talking about would immediately set the setting to whichever you made the shortcut for. You can make shortcuts for all the power plans. Open cmd.exe and type: powercfg ...
Typical laptop LCD (without backlight) uses really low power (maybe 0.1W?). If you turn off LCD completely you will see latency after turning on. Graphics card and operating system has to reinitialize everything. I guess that reinitialization could use more energy than you could save by turning off LCD completely for a while and this may be the reason.
Where did you travel to? I don't think your laptop not charging had anything to do with the earth pin. My guess is the voltage or current you where getting through that outlet was below the specs of the charger and that's why it didn't charge. Another hipothesis is the two connected pins failed to properly come in contact with the outlet, or the adapter was ...
