I had this happen to my two iPhone 7’s, two different phones. Apple fixed it both times. Take it into the Apple Store, they should repair it under a recall. They will provide a loaner phone. The phone can’t get out of recovery mode because of a hardware failure.

The coffee more than likely damaged the micro switch. There are quite a few in there. If you are ok with taking it apart and trying to clean the button with alcohol. That would be my first step. If that didn’t work, you would have to replace the microswitch. That would require soldering. There is a ifixit guide to take your mouse apart: Remplacement de la molette de défilement du Logitech G502 Proteus Core

Let the phone charge over night or a minimum of 5 - 8 hours. If it still doesn’t turn on. Return it to Amazon. It would also help if you posted the phone type (Samsung/Apple/Google)

As mentioned earlier, there is a mechanical switch by near the break foot pedal arm. It could be disconnected/faulty/broken. The other option could be a fuse that needs to be replaced. Check your fuse box. The first thing you should do before you go changing fuses is to pull the light out of the brake light housing and check the brake lights with a multi-meter. You can also use a multi-meter to check the fuses to make sure they are still working.

You could have one of two possibilities. 1. Your power plug/jack in your laptop might be broken. I had a similar situation. The computer would only start with the battery. Switching batteries allowed the computer to work until it drained. I had two identical laptops and I would switch the batteries out to confirm that it wasnt the battery or power cable. After testing the power plug/jack inside the laptop while connected to the power adapter cable, I determined that the power plug/jack was damaged internally and wouldn't allow the battery to charge properly. 2nd possibility is that the charging/power section in the laptop motherboard might be toast. A motherboard swap would be required. A new/refurb motherboard is the last thing I would change. Just did a quick ebay search and found a few under $30 shipped. Again, last resort would be a motherboard swap.

Tire sensor is inside the tire attached to the rim. Unless you have the proper tools to remove a tire from the rim I suggest you take it to Americas Tire/Discount tire/ any tire place to replace the sensors/valve for you. You can purchase one from the tire shop. If you have figured out which sensor is broken you have done half of the job.

Sounds like your lense is dirty. There are three options for cleaning it. One is to take it apart using a guide from here. 2nd option is to buy an official cleaning disc from Nintendo. Third option is to make a cleaning disc using cardboard, an old CD, tape and a micro fiber/ cleaning cloth. If one lense cleaning doesn't work, try cleaning it again. As a last resort you might need to replace the reader head or the whole drive.

You need your serial number and follow the directions in the link. On most computers with Mac OS X, you can find the serial number in the About This Mac . https://support.apple.com/en-us/HT201300

It seems to be an issue with the operating system software. There are at least three ways to get your phone to turn off. One is to force restart it (home and power button) and let the software reset then shut it down. two, turn the phone to never auto lock and force the brightness to full power until the phone powers down. That's if you have access to the settings and your phone is not locked up because of a bad install. The third option is to force the phone into DFU mode after the restart and erase and restore all the software.

The tape you are referring to is not required to have your phone working. It acts as a shield or antenna depending on how your phone is setup to use it. I forgot what it is called, but it is usually made of copper. Edit: it's called copper foil tape/EMI tape. And the shielding properties of the foil prevent the phone from potentially messing with other electronics.
