ProBook 640 G2 Windows 10 Pro (64 bit) i5 6th gen processor 8 gb ram 128 gb SSD
When I press the power button on my ProBook 640 G2, the backlit keyboard flashes but the laptop doesn't boot up. The keyboard continually flashes on, then goes off for a short time, and repeats until I press and hold the power button. When the keyboard flashes, the wi-fi and power lights on the front come on together, go off, and then the battery light comes on and goes off. This is repeated in sync with the keyboard lights.

Hi,
When you power on the laptop, the Caps Lock should blink in a specific pattern to indicate the source of problem. The blink codes are described in this HP Video: https://www.youtube.com/watch?v=5MNl-_uNOWM
Report back here with the error code and let's see if it can be repaired.
