Latitude E6430 doesn't start after upgrading RAM
Hi.
I tried to upgrade the RAM, but after installing the new modules the laptop doesn't get to BIOS - it just powers on and the screen stays blank. I returned the original modules, but nothing changed. Sometimes it just keeps working for hours, sometimes it turns off by itself (in this case the indicators start blinking).
After several dozens of attempts I managed to get to BIOS with one original module installed. I ran diagnostics, it didn't show any issues. Then I installed the other one - the problem returned and stayed even after removing the second module. I tried both slots in different combinations.
I checked all the modules on other laptop, they are fully functional. Does anyone recognises this problem? Is there a procedure to solve this?

Unplug the system, remove the battery and hold the power button for 30 sec. Then retry the one module at a time - in each socket -- until you isolate the bad module or socket. If you can't get anything after doing this (or if it turns out one of the sockets is bad), it's replace the mainboard time.

Well, all the modules and sockets are okay, since the laptop managed to boot with both original modules.
The problem appears only when I change the RAM configuration.
Though I will try to hold the power button for 30 seconds (I thought 10 seconds is enough).

It isn't clear from your post that is the case. If it is, the answer: the new RAM is either faulty or incompatible.
Check with the supplier from whom you purchased the RAM.
