The RAM is not connected properly or it may have become damaged
you know it is useless to power up a battery powered computer without RAM so it blinks twice to tell you the situation then stays off.

try replacing the RAM with a new one

    if you get the led symptom then the motherboard / RAM slot has an issue and if there is no life without battery then the adaptor or its connector is bad

SOURCE: Battery light on my hp probook 6550b flashes when i try to charge it but it will not turn on!!! How do i fiix it?

flashing battery light is normal when the battery is empty ,and the orange led should become steady when you insert charger then it should turn to blue and after the battery is fully charged the led is turned off, i think the problem is that no charging happens check your adapter and the DC input

SOURCE: blinking white amber light above power cord

The power supply is the issue, or the DC jack in the laptop has developed bad connections, or ram issue. Remove 1 stick of ram and power on, if no! remove second one, and replace the first, power up, if no! test the power supply for proper voltage, if okay! it is a DC jack or motherboard problem.

SOURCE: hp probook 4530 ac connected indicator flashing. will not power up

Remove the battery, Plug in the AC charger. Push and hold the Power on button for 45secs. If this doens't reset. The fault is most likely the System/Motherboard. If the unit is under warranty, contact HP and arrange a repair.
