Early 2013 13" MacBook Pro requires power cycle to boot
I left my 2013 13" MacBook Pro for a month and a half on my desk and did not use it, after trying to turn it on it wouldn't boot, when I put my ear on it to hear for any signs of life, I heard a weird fan noise, like something was jammed in one of them. I took my screw driver set and opened the computer, I pressed the power button and saw the fans spin, then stop, then start again, then stop. I unplugged the battery just in case it is a battery related issue, after attempting to boot without the battery connected I got the same results, I have never encountered anything like this, I google up and after gathering some information I perform something called a "power cycle", Hold power button for 10 seconds then plug the computer while holding the power button for another 10 seconds, adding up to a total of 20 seconds without letting go. The fans suddenly go at full blast and the computer turns on, the light on the magsafe power cable is off the power button. In MacOS using macs fan control it asked me to reset the SMC and no sensors were detected, in System Information no battery was detected, only the AC Power Adapter was showing up. I unplugged the laptop and it shut off immediately. After resetting the SMC the computer wouldn't boot normally and I had to perform another power cycle so it boots with the fans again at full blast. Is this an Issue with the SMC that no battery, fans and temperatures are detected or is it something else. I also wanted to mention that the computer was running much slower than usual while going through the menus and trying to operate it.
