    Fault RAM is by far the most common cause of no display issues in laptops, thats why before checking anything else on a no display laptop its wise to start with RAM. You must have good known working RAM around to easily diagnose these issues faster.

    Start by removing the and cleaning the RAM chip with motherboard cleaning chemical, focus on the RAM teminals and the slot pins, but remember not to use excessive force since this can damage or bend RAM slot pins.

    Then swap the RAM in the other slot, sometimes these slot pins get corroded or even break off from the motherboard, so changing the RAM slot is the best solution in this situation.

    If non of the above works then just getting another RAM chip is the best solution, and most times this fixes the problem.

    Note, dont waste your time fixing RAM chips when they fail they fail for good
