I have this Dell Latitude 5420 with ST: CMF62F3, board GDF40 LA-K491P REV 3.0 that does not power on, i already searched for some clues about this problem that happens on mine but no BIOS i downloaded and flashed did anything.
Only when the power brick is connected, when pressing the power button an amber light lights up at the front and slight decreases its brightness, the RAM and the CPU seem to heat up if the laptop is left connected but nothing else, other than USB devices getting powered.
Here is the original BIOS dump from the 25R256JVEN chip. -

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...10-13-2024, 10:29 AM -
