I have a feeling FS is the prob. Hope the prob is solved. Tried 1 more shutdown & started system after 20 mins & fine.
2 reasons I get the feeling FS is the prob. 1. System booting fine with 7-8 test shutdown/start & 2. No screen flicker. The screen use to flicker sometimes when I use to move shutter front back or lift the system but tried many times now & no screen flicker.
And FS disabled is good for my family members. Coz with FS enabled screen goes black instant but keyboard led takes time to shut off that means system is not completely shutdown, right? So I always close the shutter when led goes off but my family members the moment screen goes black they close the shutter. With FS disabled on shutdown when the screen goes black keyboard leds too go off that means complete shutdown...this is good for my family members.
Tomorrow will post the update here. If tomorrow system boots fine then couple days later will post the update here. If couple days later system is still fine then few days later will post the final update here.
Fingers crossed for tomorrow.
