Hi everyone!
I have a Dell Latitude 5591. It has a strange problem:
First, when the WLAN card is plug in, it will not power on when press power button, even all voltage is up (19v, 3v, 5v, 3valw, 5valw)
When I remove the WLAN card, it will start nomarlly. Then I power off and re-insert the WLAN card, it still work normally.
But, if I left it for 3 or 4 days without the battery and adapter plugged in, it will not power on, and I have to repeat the above sequence.
Sometime, when it not power on, I just unplugged the battery and adapter, wait for some minutes, and it will power on, but it is kind of random.
Please help me diagnose where the problem is.
Thank you!
