Hi, My laptop is not booting, not even BIOS or manufacturer logo. I have checked the RAM,tried resetting CMOS battery,removed HDD.At first it worked for 2-3 times but after 5-6 hour when I turned on, it is not working. I don't think it is a display issue because windows key+B does not produce any beep. CPU fan is working okay.Please help.

No, there are no blinks. At first I tried without battery it worked for one night,next day I tried with RAM reset and after that with CMOS reset. It worked for one night of usage,the next morning it was not working again. I thought it may be display problem,but the BIOS reset key combo are not producing any beeping sound.

Can a faulty power connector cause black screen? The connector which connects the power button and mother board is in bad condition.

Yes. Very possible. There seems to be a loose connection between lcd and motherboard or dome issue with the motherboard itself
