I will forward you the info I found regarding this which I found on the Promark website. Did you download on your smartphone the Promark VR aerial photography app? Then HOW TO CONNECT 1-Download the Promark VR app for iPhone or Android. 2-Power on the drone. 3-Open the WiFi settings on your phone and connect to “P70-VR” WiFi. Tip: you may need to reset your WiFi by turning it off and then back on again. 4-Once connected, open the Promark VR app and press “Play” 5- For VR streaming, click the “3D” button on the screen and place your phone into the Promark VR 3D Goggles (included in the P70-VR drone). Shut down the drone and turn it back on if it is still does not show. Hope it is helpful
According to Apple "Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015. If you have experienced this issue, please use the serial number checker below to see if your iPhone 6s is eligible for a battery replacement, free of charge."
You may want to make sure the reason of your system sluggishness is not caused by malware. I will run first CCleaners & Malwarebytes Anti-Malwares first (you can download those for free in Cnet.com). Then if it looks good, you can go on www.crucial.com which will scan your system and tell you the proper upgrade for your system, so you don't buy or install the wrong one as it will destroy your system. Make sure you follow proper installation which you can find on ProfessorMesser.com Good luck!!
Few things you can try first, make sure your outlet is working by plugging another device in. Next, check your laptop power cord to make sure the two pieces are seriously plug in each other. Also if you got a spare power cord, this is the best option to find out if this is causing the issue. If everything is fine, put your laptop to charge for 1 hour. It may not display any light as it is charging even if the light is broken but it should not stop your laptop from turning on after sufficient charge. Now if you press the power button and still nothing, keep on pressing and holding to the power button until you get a reaction. If nothing happens, disconnect your power cord from your outlet or power supply, keep pressing on the starting button for at least 30 seconds to drain the power charge out, then removes the battery from the laptop, if no sign of unusual wear, put it back and try again. Let me know if you got result.
