Re: Inspiron E7450 wierd Power on Issue

thank you for your reply, i got the boardview software and the cad file for this board.
Can you point me in a direction where to search? Maybe a hint where to find the rtc circuit? is this a dedicated part or part of a big asic?

than you very much.

I got a E7450 that was dead. First i removed accu and Bios Battery.
Then i pressed the power on button for 40 seconds.
After plugging in the power brick, it comes to live.
I plugged BIOS Battery and the accu back in to the computer in on state.
The laptop runs fine until i shut it down. Then dead again.
Now i have to repeat the precedure to get it runnig again over and over.
I was able to flash the latest A24 BIOS, no change of behavior.

At the Dell Forums is a rumor that this issue may be a engineering defect/design issue.
