Acer 6930g-no power
Acer 6930 gr. I turn on the power. The lights come on for 1-2 seconds and the laptop shuts down. When the hard drive is disconnected, the laptop starts normally!!! I have done bios programming, NorthBridge refresh. Nothing changed. Maybe the hdd controller is at fault? Who is the controller? Motherboard da0zk2mb6e0 rev e

Re: Acer 6930g-no power
Have you checked with a second hdd too?
If not the hdd could have a short and it's shorting the power rails.
Also the hdd is connecting to the southbridge so do a visual check there and at hdd motherboard connector. -

I tried another hard drive,i checked the motherboard hdd slot.No result.
Where are the hard drives usually connected to the motherboard? To the southbridge or on some controller? Τhere is a short circuit somewhere...Comment

Re: Acer 6930g-no power
Your motherboard has 4 data lines from hdd to southbridge.
Also takes the 3,3V and the 5V.
You could measure if there is voltage drop at the two power lines when you have the hdd connected.
You could also try if you don't use the dvd drive to remove it and place a hdd caddy there to put the hdd there.Comment
