Hi. The fan in your computer works automatically to cool down the internal components to prevent them from overheating. To slow down the fan, you need to cool down your computer. You can do this by putting less strain on your computer, by doing things like deleting unwanted programs, removing viruses, and limiting the amounts of processes running on your computer. Here’s a guide: https://www.google.com/amp/s/www.pcmag.c...
To remove and clean the keys: To clean keys without removing them, just use a towel or rag with some isopropyl achohol and brush them over the keys. To clean under the keys, Use your finger or a flathead screwdriver and GENTLY lift them off the keyboard by rotating your finger/ screwdriver, and prying the key off. Now you can clean your keys individually. Hope this helped.
Okay..... um kinda a weird question but I'll try my best to answer it. Try taking the Etch a Sketch, turn it so the pure red part is facing you, otherwise, the one with no screen. Start shaking it and it should work. If this doesn't work... uh... shake harder?
If the menu and other things are in color, than it's probably not a hardware problem. My guess is that whoever had the TV before you inadvertently switched it to black and white. Look in the settings of the TV, (especially under display) and try to find an option that says "Color" or something like that and make sure it's switched on.
I found this on the internet for the J3. It's probably an identical (if not then very similar) process. From a Home screen, navigate: Apps > Samsung folder > My Files Select an option (e.g., Images, Audio, etc.). Tap MORE (located in the upper-right). Tap Edit then tap the desired file(s). Tap MORE. Tap Move. Tap SD card. Navigate to the preferred folder then tap DONE (located in the upper-right). (From : https://www.verizonwireless.com/support/...-base-204547/)
iPhones, unlike Samsung phones, are very hard to get into and repair. If you really wanted to give it a go yourself, you can buy a new antaenne on IFixit for 14.00 and try to replace it. The antaenne is located in the top of the phone. (The anatanne for wifi and cellular service are different parts) If you don't want to go through that and risk messing up your IPhone, you should probably take it to a professional repair place.
I don't know about that specific model, but most keys are fairly simple to remove. Before you remove them, just try to clean in and between the keys. This might help. If this doesn't work, you can remove the keys. To do this: 1. Turn your computer off 2. Slide your finger or a flathead screwdriver under the keys you want to remove. 3. Lift GENTLY until the key comes off. 4. Rinse and repeat. Now you can clean/ troubleshoot the troublesome keys. Keep in mind it may be a problem with your device and not the keyboard itself.
To troubleshoot this problem : Plug something else into the same outlet. If it doesn't work, than it's a problem with that outlet. It could also be a problem with the power chord. Make sure it's connected correctly. If you can, try to use a different one. Check the connectors on the power chord and the outlet on the PS4 itself for sign she of damage. If none of these work, it's probably a problem with the power supply. These are quite common, but you're probably have to take it in to a repair place. I personally sent mine in to TronicsFix and I would highly recommend them if you decide to send it in. If not, there are various guides in the internet to replace the power supply yourself.
