Hi,
I have a Latitude E6430 laptop. It was working perfectly until recently, but started to show some issues with powering on.
After being shut down or on sleep mode for a long time (more than 3-4 hours), the laptop won't power on. When the power button is pressed, it lights up, and after few seconds, the LED turns off and does nothing. Not even the Dell screen splash is shown. I've tried removing the battery & AC power and pressing the power button for 30+ seconds and powering on, removing all drives and powering on, swapping RAM modules, and re-attaching the CMOS battery. None of them worked.
Only thing that worked is removing the main battery and AC power for couple of hours and then powering on. Then the laptop will power on and boot and function properly (until it is powered off or put into sleep mode again).
Now, being an old computer, I understand there can be hardware issues. Any suggestions to resolve this issue is welcome. Thank you in advance!
