Yesterday i thought it would be a good idea to take some underwater ab pics with my waterproof phone. After being...

I recently purchased a XS Max for $350, and after transferring from my old Sony XZ Premium, I have noticed a huge...

I was walking my dog when i dropped my phone. Upon later inspection I found the back glass to be shattered and it would...

I finally figured out the issue. The phone turns on completely fine and everything works when the flex cable for the touch digitizer and 3d touch is unplugged. I applied some isopropyl alcohol to the back of the screen, mostly around the areas where i could see components. After sitting for a while, I brushed it off and used a heat gun on it for about five minutes, and when i assembled the phone again everything was fully functional except the haptic feedback.

I had the exact same issue with my XS Max. It started to flicker green after being in the water for a couple seconds, then completely shut off. I left it in rice for two days, which i thought was complete bullshit but somehow actually worked. The phone would turn on and function but the screen was still plagued by the green hue and constant flickering. I held it vertical and used a hairdryer for about ten minutes, and the phone began working again, excepting Face ID. None of my water sensors were triggered. I first tried contacting apple support but apparently water damage is not covered by warranty.

when its booting up, hold command and R. a globe will appear and it will say internet recovery. then it will boot into mac os utilities. click reinstall mac os and follow the onscreen instructions.

This has happened to me as well. What you can do is replace the DC in power adapter (this is an internal circuit board) and you can order it from eBay for about 10 bucks.

shut it down and then hold the power button and volume down (or up) for fifteen seconds. it should vibrate three times. then you can use the volume keys to navigate to the restore to factory settings option

When it boots up hold command & R to boot into recovery mode. Open Disk Utility and reformat the drive you are using. Then quit Disk Utility and open Reinstall MacOS Sierra and follow the onscreen instructions. Also you can hold shift, control and option to reset the SMC.

Most probably your MagSafe board is dead. to remove it you must remove the logic board then unplug it from the logic board. They are very cheap, usually about 10 bucks on eBay. Hope that helped, looks like you spent a lot of money on logic boards.

open the bonnet and look at the carburettor. on the right side there should be a little lever that is pulled by a cable. if this is stuck on it shouldd be the problem

What could have happened was the keyboard cable got disconnected or cut. A similar thing happened to my MacBook Pro. What you can do is unscrew the bottom plate, and when the computer is plugged in, create a short between these two pads. This will basically be the same as pushing the power button. If you want to repair the keyboard and trackpad, unplug the battery and power adapter. The battery connecter is located on the far left beneath the power pads. Check the other cables next to the battery connector for breaks or if they're disconnected. and if they are fine that must mean that the cable has been broken further along the line. To find the break you have to remove the logic board. Just Google 'how to remove logic board on macbook air 13'. Hope that fixed your problem.

is it normal to have a clogging substance in between the heat sink and the chips?
